Which group is best served by the development of a rigorous base of evidence for nursing practice?

A) Nursing administrators B) Practicing nurses C) Nurses’ clients D) Nurse researchers Ans: C Feedback: Nurse leaders have recognized the need to base specific nursing decisions on trustworthy evidence indicating that the decisions are clinically appropriate, costeffective, and result in positive outcomes for their clients. Nursing groups benefit from nursing studies, but it is nurses’ clients themselves who benefit most because research-based evidence can improve their health and health-related quality of life.

Ans: B Feedback:

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice The answers to clinical nursing research questions have the potential to improve the health and well-being of nurses’ clients. Clinical nursing research questions focus directly on clients’ needs, experiences, and health behaviors, and answers to such questions can inform nurses’ decisions or lead to strategies to improve nursing practice. Researchers also study nursing education, but questions about nursing education, as exemplified in the other questions, would not be considered clinical nursing research questions.

Which goal is the highest priority for research in the nursing profession?

A) To generate evidence to inform nurses’ decisions and actions B) To conduct research focused on the context of nursing practice C) To document the role that nurses serve in society D) To establish priorities for areas of study by nurse researchers Ans: A Feedback: Nurses are increasingly undertaking clinical research, and practicing nurses are expected to base their practice on evidence from research. Evidence-based practice involves the use of the best evidence in making patient care decisions and typically comes from research conducted by nurses and other health care professionals. The other answers are possible goals for the nursing profession, but none is as high a priority as developing rigorous evidence for practice.

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice B) credentialing and improving nurses’ status.

C) strengthening nurses’ bargaining power.

D) supporting better avenues for advanced degrees.

Ans: B Feedback: In the United States and in other countries, research plays an important role in nurses’ credentialing and status. In particular, research and efforts to promote evidence-based practice are key elements of the Magnet recognition program.

Changes to nursing practice now occur regularly because of EBP efforts, and these efforts enhance the status of the profession. The other answers are possible outcomes of increased research activity among nurses, but none is as important as the role of research in enhancing the visibility and credibility of the profession.Format: Multiple Choice Chapter: 1 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Analyze Difficulty: Easy Integrated Process: Nursing Process Objective: 01 Page and Header: 3, Roles of Nurses in Research 5. What is the role of consumers of nursing research?

A) Generating evidence by undertaking studies B) Gathering information from clients that can be used in research C) Coming up with ideas for studies D) Reading research reports to find evidence that is relevant to nursing practice Ans: D Feedback: Knowledge of nursing research enhances the professional practice of both consumers of research (who read and appraise studies) and producers of research (who design and undertake studies). Between these two points on the consumer– producer continuum lies a rich variety of research activities in which nurses may engage. These activities include contributing an idea for a study, advising clients about their participation in a study, and searching for research evidence.

A) Development of an idea for a journal article B) Presentation by the author of a research article about the article’s central ideas C) Testing of participants on their comprehension of selected journal articles D) Discussion of a research article regarding its merits and relevance to practice Ans: D Feedback: Journal clubs exist in many practice settings, as an opportunity to share and discuss new evidence of relevance to clinicians. Journal clubs sometimes involve face-toface group meetings but also can involve online discussions to accommodate diverse schedules. Participants in a journal club do not develop ideas for a journal article, hear a presentation by an author, or get tested on journal article content.

A) In the early 1900s, most nursing research focused on education, not nursing practice.

B) Clinical nursing research has made steady progress since the work of Florence Nightingale.

C) Several nursing research journals began publication in the late 1800s.

D) The National Institute of Nursing Research was established in the United States in 1943.

Ans: A Feedback: After Florence Nightingale’s research in the 1850s, nursing research did not progress for many years. Early in the 1900s, nurses began to engage in research, but the focus was mainly on education, not nursing practice. No nursing journals focused on research until the 1950s. The National Institute of Nursing Research was established in1993, not 1943.

Improving nurses’ attitudes toward research and students’ interest in doing research—and having better methods for doing research—are important objectives, but attending to the applicability of research findings is likely to become an increasingly important goal for nurses pursuing an evidence-based practice.

Format: Multiple Choice Chapter: 1 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Understand Difficulty: Easy Integrated Process: Nursing Process Objective: 03 Page and Header: 5, Knowledge Sources for Nursing Practice 10. Which is a compelling source for answering clinical questions in evidence-based nursing?

A) Input from an authorit B) Intuition C) Disciplined research D) Nurses’ clinical experience Ans: C Feedback: Nurses are increasingly expected to understand and undertake research and to base their practice on evidence from research—that is, to adopt an evidence-based practice (EBP). Experience, intuition, and authority are not wholly ignored in the EBP process, but research findings comprise a crucial source of evidence.

Format: Multiple Choice Chapter: 1 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Apply Difficulty: Moderate Integrated Process: Nursing Process Objective: 03 Page and Header: 5, Knowledge Sources for Nursing Practice 11. If nurses make clinical decisions by following “unit culture” practices, they are using which source of knowledge?

A) Tradition and authority B) Intuition C) Disciplined research D) Trial and error

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice Ans: A Feedback: Many decisions are made based on tradition or the guidance of an authority. These types of knowledge are so much a part of a common heritage that few people challenge their efficacy or seek verification. Such “sacred cows” are widely used to guide practice, but they are a weaker form of knowledge than disciplined research.

Clinical experience is a functional source of knowledge. It also has limitations as a source of evidence for practice because each nurse’s experience may be narrow.

Trial and error are alternatives tried successively until a solution to a problem is found. It can be practical, but the method tends to be haphazard and solutions may be idiosyncratic.

A) An assumption about the nature of the world B) An antecedent cause of reality C) A set of procedures for studying the world D) A worldview, a general perspective Ans: D Feedback: A paradigm is a broad worldview—a general perspective on the complexities of the real world. A paradigm is not an assumption, although alternative paradigms have assumptions. A paradigm is not an antecedent cause of reality, nor is it a set of procedures for understanding the world.

A) Reality is “out there” and can be objectively studied, known, and understood.

B) Phenomena do not necessarily have an antecedent cause.

C) Reality is not orderly but rather is haphazard.

D) Reality is not a fixed entity but rather is a construction of the human mind.

Ans: A Feedback: In the positivist paradigm, it is assumed that there is an objective reality, that natural phenomena are regular and orderly (not haphazard), and that phenomena have one or more antecedent cause that can be understood through research.

Positivists assume that reality exists and is independent of human observation.

Which is a central assumption in the constructivist paradigm?

A) A fixed reality exists in nature for humans to understand.

B) The nature of reality has changed over time.

C) Reality is multiply constructed and multiply interpreted by humans.

D) Phenomena are not haphazard and result from prior causes.

Ans: C Feedback: In the constructivist paradigm, it is assumed that reality is not a fixed entity but is rather a construction of human minds—and thus, “truth” is a composite of multiple constructions of reality. Constructivists do not assume that a fixed reality exists in nature for humans to understand, nor that all phenomena have antecedent causes.

Constructivists do not believe that the nature of reality has changed over time but rather that it has always been constructed by human minds.

The scientific method is associated with which paradigm?

A) The positivist paradigm B) The constructivist paradigm C) The naturalistic paradigm D) The empirical paradigm Ans: A Feedback: The traditional scientific method involves the use of systematic and orderly procedures that are high on objectivity, consistent with the assumptions of the positivist paradigm. An important assumption of this paradigm is that values and biases of researchers can be held in check through disciplined strategies with tight controls. Those who espouse the constructivist (naturalistic) paradigm do not adhere to the tenets of the scientific method. There is no such thing as an “empirical” paradigm.

A) A flexible, emergent design B) A holistic view of a phenomenon, studied in rich context C) An inductive reasoning process D) The systematic measurement of natural phenomena Ans: D Feedback: The scientific method refers to a set of orderly, disciplined procedures used to acquire information, and this includes the systematic measurement (quantification)

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice of natural phenomena. Investigators gather quantified data (make measurements) in a preplanned manner, using methods that are consistent across people participating in the study. Constructivist researchers tend to emphasize holistic and individual aspects of human life and use inductive reasoning and flexible designs.

Format: Multiple Choice Chapter: 1 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Understand Difficulty: Moderate Integrated Process: Nursing Process Objective: 04, 09 Page and Header: 7, The Scientific Method and Quantitative Research 17. What is empirical evidence?

A) Evidence derived from inductive reasoning B) Evidence derived from personal insights and beliefs C) Evidence rooted in the real world, gathered through the human senses D) Evidence based on custom or an expert/authority Ans: C Feedback: Researchers gather empirical evidence that is rooted in reality and gathered through their senses. The requirement to use empirical evidence means that findings are grounded in reality rather than in researchers’ personal beliefs.

Inductive reasoning is the process of developing generalizations from specific observations and is associated with the constructivist paradigm. Evidence from custom or authority is not typically empirical—based on information gathered through the human senses in a systematic manner.

Format: Multiple Choice Chapter: 1 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Understand Difficulty: Easy Integrated Process: Nursing Process Objective: 04 Page and Header: 7, The Scientific Method and Quantitative Research 18. What is a hallmark of the traditional scientific method?

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice A) Holistic strategies B) Systematic procedures C) Infallible methods D) Flexible procedures Ans: B Feedback: The scientific method refers to a set of disciplined, systematic procedures used to acquire knowledge. The investigator progresses logically and systematically through a series of steps, according to a prespecified plan of action. Constructivist researchers tend to emphasize the holistic and individual aspects of human experience using flexible designs and procedures. No method of inquiry is infallible.

Format: Multiple Choice Chapter: 1 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Understand Difficulty: Moderate Integrated Process: Nursing Process Objective: 04 Page and Header: 7, The Scientific Method and Quantitative Research 19. What is a limitation of the scientific method for answering questions about human experiences, characteristics, and health outcomes?

A) The difficulty of accurately measuring complex human traits B) The shortage of well-trained researchers C) The scarcity of ideas on what to study D) The shortage of theories about human behavior Ans: A Feedback: One important limitation of the scientific method for studying humans is that human beings are highly complex. Human characteristics are extremely difficult to measure (quantify) in an accurate, valid, and objective manner. At this moment in history, there is an abundance of ideas on what to study, many theories of human behavior, and thousands of well-trained researchers poised to make advances in understanding human health.

A researcher is investigating the effect of the bed angle of hospitalized patients (15 degrees, 30 degrees, 45 degrees) on the patients’ blood pressure. This is an example of what type of study?

A) A qualitative study B) A quantitative study C) A constructivist inquiry D) Cannot be determined—it depends on the researcher’s methods Ans: B Feedback: Quantitative research involves systematic measurement, and in this example, both bed angle and blood pressure would be carefully measured, recorded, and analyzed. The researchers chose the question to address, but the type of study (quantitative) is dictated by the question of whether bed angle affects heart rate.

Constructivist studies are heavily focused on understanding the human experience as it is lived, usually through the careful collection and analysis of qualitative materials that are narrative and subjective, which is not the case in this example.

A persistent criticism of the scientific method by those who espouse the constructivist paradigm is that it is: A) deductive.

B) laborious.

C) empirical.

D) reductionist.

Ans: D Feedback:

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice Researchers who reject the traditional scientific method believe that it is overly reductionist, in that the scientific method reduces human experience to the few concepts under investigation. Moreover, those concepts are defined in advance by the researcher rather than emerging from the experiences of the people under study. The scientific method is seldom criticized because it is deductive, laborious, or empirical.

Which statement is true about qualitative research?

A) It focuses on the idiosyncrasies of those being studied.

B) It attempts to have tight control over the research context.

C) It involves the gathering of narrative, subjective materials.

D) It focuses on the collection of numeric information.

Ans: C Feedback: Qualitative researchers attempt to understand human experience as it is lived through the collection and analysis of subjective, narrative materials, gathered using flexible procedures. Qualitative research does not impose controls on the research context, nor does it focus on the idiosyncrasies of those being studied.

Qualitative researchers do not emphasize numeric (quantitative) information, but rather collect in-depth narrative information.

Which is a potential limitation of qualitative research?

A) Qualitative research typically involves a small number of people, so the generalizability of findings can be a concern.

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice B) Qualitative researchers ask questions that tend to have limited significance in nursing.

C) Qualitative research is overly reductionist and tends to remove concepts from real-world contexts.

D) The quality of qualitative research is undermined because of difficulties in measuring phenomena.

Ans: A Feedback: Qualitative research usually involves a small number of people participating in a study, and it is sometimes difficult to know whether the findings would be true of a broader group of people. Qualitative researchers ask many questions of deep significance to nursing and other health care professionals. Quantitative research (not qualitative research) is sometimes accused of being reductionist because of its focus on a limited number of concepts. Qualitative researchers do not “measure” phenomena quantitatively.

Although the positivist and constructivist paradigms differ in many ways, the two paradigms have which feature in common?

A) Both rely on the cooperation of human beings to participate in a study.

B) Both have as a major goal the identification of the causes of phenomena.

C) Both involve the application of the scientific method.

D) In both, generalizability is a key objective.

Ans: A Feedback: Regardless of paradigm, nursing research most often involves the collection of information from human study participants. Without the cooperation of others, research would not be able to measure human attributes (quantitative research within the positivist paradigm) or gather in-depth narrative information (qualitative research within the constructivist paradigm). Unlike the constructivist paradigm, the positivist paradigm is associated with efforts to identify causes of phenomena, involves the scientific method, and strives for generalizability.

B) Does postpartum depression predict toddlers’ temperaments?

C) What is the experience of loneliness like among caregivers of patients with Alzheimer’s disease?

D) What is the prevalence of elevated salivary cortisol in adolescents?

Ans: D Feedback: Quantitative description focuses on the prevalence, size, and measurable aspects of phenomena, such as the prevalence of elevated salivary cortisol. Qualitative researchers ask descriptive questions about the nature of phenomena, such as sudden confusion and loneliness. Descriptive questions do not focus on predictions, such as the extent to which postpartum depression predicts toddlers’ temperaments.

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice B) Are students who use e-cigarettes at higher risk of respiratory infections than students who do not?

C) What are the characteristics of students who vape (use e-cigarettes)?

D) What is the process by which students initiate using e-cigarettes?

Ans: B Feedback: The question about the use of e-cigarettes in relation to respiratory infections basically concerns whether vaping might cause respiratory infection in some students. Two other questions are descriptive: the prevalence of vaping (quantitative description) and the process by which vaping is initiated (qualitative description). The question about student characteristics and vaping is not necessarily cause-probing—for example, one factor might be gender: Are males more likely than females to vape? This does not imply that gender might cause different rates of vaping.

Most definitions of evidence-based practice (EBP) call for the integration of best research evidence with: A) patient preferences and values.

B) well-worded clinical questions.

C) systematic reviews.

D) rankings on the evidence hierarchy.

Ans: A Feedback: Evidence-based practice, according to definitions offered by leaders in health care, calls for integrating best evidence from research with both patient preferences and clinical expertise. The evidence itself is often derived from (not integrated with) systematic reviews, which can be retrieved by asking well-worded clinical questions. The quality of evidence is sometimes ranked on evidence hierarchies according to the study’s methods.

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice B) To guide researchers in selecting a research design C) To rank order evidence according to the strength of evidence provided D) To provide an incentive structure for those undertaking research Ans: C Feedback: Evidence hierarchies provide a framework for understanding the strength of evidence of a study and its risk of bias. Every study can be ranked, usually based on its design, within an evidence hierarchy. Several evidence hierarchies have been published, but most are hierarchies for ranking evidence for Therapy questions.

Evidence hierarchies do not play a role in creating a systematic review, and they are not intended to serve as a guide for selecting a research design or to provide an incentive structure.

Most evidence hierarchies and level of evidence scales put which evidence source at the pinnacle?

A) Randomized clinical trials (RCTs) B) Systematic reviews C) In-depth qualitative studies D) It depends on the research question.

Ans: B Feedback: Regardless of the type of question being asked, systematic reviews are at the pinnacle of evidence hierarchies because such reviews are rigorous syntheses of all the available evidence on a topic, using information from multiple studies.

Randomized controlled trials are high on the hierarchy for Therapy/intervention questions, and in-depth qualitative studies are high for Meaning/process questions, but systematic reviews can be undertaken for all types of research questions.

In this study, the experience of living with IPF would most likely be called the: A) construct of interest.

B) variable of interest.

C) phenomenon of interest.

D) theory of interest.

Ans: C Feedback: Qualitative researchers refer to the abstractions in which they are interested as phenomena. Quantitative researchers are more likely than qualitative researchers to describe the key focus of their research as a construct or variable.

A) As a basis for developing hypotheses B) As a tool to direct the research project C) As a product of the research D) As a strategy to gain entrée into a research setting Ans: C Feedback: A theory is an explanation of some aspect of the real world. In qualitative studies, theory often is the product of the research—that is, a theory is developed based on what the qualitative researcher discovers. In qualitative studies, theory is not used to develop hypotheses, nor is it a tool to direct the study or to help gain entrée into a research setting.

A) An independent variable B) A dependent variable C) Not a variable D) The type of variable would depend on the research question.

Ans: C Feedback: A variable is a characteristic or quality that takes on different values (i.e., varies from one person or object to another). “Male” does not take on different values and so is not any type of variable; it is one of the values for the variable gender. In a study, the variable gender is most likely to be an independent variable—that is, the presumed influence on the dependent (outcome) variable.

B) Variables in a study can be intrinsic human traits or can be created by researchers.

C) Abstractions with a few categories are not considered variables.

D) In a study of older people in a nursing home, age would be a constant.

Ans: B Feedback: Variables (abstractions) are often intrinsic human traits (age, fatigue levels, blood type), but can also be created (e.g., when a researcher compares the effects of an innovative intervention versus standard care). By definition, the independent variable in a study would always vary. Variables can be on a continuum with many possible values (such as the variable body temperature) or can be categories with only a few values (such as blood type). In a study of older people in nursing homes, age would almost surely vary (e.g., from residents in their 60s to those in their 90s).

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice D) What amount of exercise is optimal for adolescents?

Ans: A Feedback: Rigorous daily exercise is a factor that can directly affect body weight and thus risk of obesity; amount of exercise can cause variation in weight. The relationship between gender and exercise, and between exercise and eating habits—if such relationships exist—are associative. Gender does not cause the amount of exercise, and eating habits do not cause exercise levels (or vice versa). The question about optimal amounts of exercise for adolescents does not ask about any type of relationship.

A) Qualitative researchers measure their variables with instruments of known accuracy and validity.

B) Qualitative data are not interpreted until all of the data have been analyzed.

C) Qualitative researchers carefully plan how many study participants will be included in the study.

D) The inductive analysis of qualitative data typically yields themes and categories.

Ans: D Feedback: The process of qualitative data analysis involves clustering together related narrative information into a coherent pattern. Through an inductive approach, researchers identify themes and categories, which are used to develop a rich description or theory of the phenomenon. Qualitative researchers do not “measure” variables, nor do they know in advance how many people will be needed in their studies. In qualitative research, analysis and interpretation occur concurrently and are used to guide “next steps” in the project.

In qualitative research, what does saturation indicate?

A) There are too many study participants.

B) Themes and categories in the data are becoming redundant.

C) Too many variables are included in a study.

D) The quality of the data is excellent.

Ans: B Feedback: In making sample size decisions, many qualitative researchers use the principle of saturation. Saturation occurs when themes and categories in the data become repetitive and redundant, such that no new information is likely to be gleaned by continuing to collect data. Saturation does not indicate that there are too many subjects or too many variables. Achieving saturation does not guarantee that the quality of the data is excellent.

What is the final step in both quantitative and qualitative research?

A) Assessing the trustworthiness of the data B) Undertaking a literature review C) Disseminating research results D) Addressing ethical issues Ans: C Feedback: In both quantitative and qualitative research, an important final step is to share research results with others, either at conferences or in publications. All researchers need to address ethical issues but not as the last step. Literature reviews are undertaken either early in the project or during the interpretation phase—not as the last step. Trustworthiness is assessed by qualitative researchers throughout the actual conduct of the study, not as a final step.

In which of the following are nurses most likely to find research evidence?

A) Wikipedia B) Journal articles C) Textbooks D) Dissertations Ans: B Feedback: Nurses are most likely to locate research evidence in professional journals, which publish articles that describe the background, methods, and results of studies. A textbook is not a primary source for research results but rather an overview of established knowledge in a field; textbooks can quickly become outdated.

Dissertations are lengthy documents that describe research completed by a graduate student. Wikipedia provides some research evidence for some entries, but it cannot be counted on to provide up-to-date, rigorous evidence on topics of interest to nurses.

Feedback: Usually, manuscripts are reviewed by two or more reviewers who make recommendations about whether to accept or reject the manuscript or to suggest revisions. Reviews are usually “blind”—reviewers are not told researchers’ names, and authors are not told reviewers’ names. Journal editors always know who submitted the article, and authors can easily learn online who the editor of the journal is. When an article is published, authorship is always indicated.

A) Peer reviewers are friends (peers) of a journal’s editor.

B) Journal articles are typically 40 to 50 double-spaced pages in length.

C) Poster sessions involve simultaneous visual displays of multiple research summaries at a conference.

D) Because journal articles are carefully reviewed, readers can assume the evidence in the article is strong and reliable.

Ans: C Feedback: Poster sessions at conferences involve having many researchers simultaneously present visual displays, and attendees can walk around perusing the displays. Peer reviewers may have a friendship with a journal’s editor, but most do not; the reviewers are other researchers and are considered “peers” of the researchers/authors, not the editor. Journal articles tend to be short—typically no more than 20 or so pages in length, double spaced. Even with peer review, studies often have some methodological deficiencies, and so the evidence cannot be accepted uncritically.

C) The use of research jargon in research articles can make the articles difficult to read and comprehend.

D) The stories described in quantitative research reports are easier to understand than the stories in qualitative reports.

Ans: C Feedback: Research has many terms and symbols that can seem esoteric, and this jargon can make research articles hard to read. Most quantitative research reports are written in the passive, not the active, voice. Because space in journals is limited, personalized aspects of a research inquiry are seldom reported. All research reports tell a “story,” but the stories in quantitative reports are more difficult to comprehend than the stories in qualitative reports.

A) Evidence-based practice B) Statistical testing C) Research critique D) Literature review Ans: C Feedback:

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice A research critique is an objective assessment of a research study’s strengths and limitations. Comprehensive critiques are often undertaken by peer reviewers who assess the merits of both the research and the report and make decisions about the publication of an article. When research evidence is being assessed for use in nursing practice, the term critical appraisal is likely to be used instead of critique.

An assessment of a study’s strengths and weaknesses is not called evidence-based practice, statistical testing, or a literature review.

Format: Multiple Choice Chapter: 3 Client Needs: Psychosocial Integrity Cognitive Level: Understand Difficulty: Moderate Integrated Process: Communication and Documentation Objective: 05 Page and Header: 51, Inference 18. A conclusion derived from the evidence presented in a study, taking into account the study methods, is called: A) statistical significance.

B) scientific merit.

C) triangulation.

D) an inference.

Ans: D Feedback: An inference is a conclusion drawn from the evidence presented in the research study, using logical reasoning and taking into account the methods used to generate the evidence. For example, the results of an intervention study might lead to the inference that the intervention caused improvements to patients’ health.

Statistical significance means that a result has a high probability of being “real.”

Scientific merit is the overall soundness of a study. Triangulation is a strategy involving the use of multiple sources to conclude what constitutes the truth.

A) The rigor of a qualitative study is sometimes referred to as its scientific merit.

B) Bias is a concern in quantitative studies but not in qualitative studies.

C) A central feature of qualitative studies is research control.

D) Rigorous research methods facilitate researchers’ ability to make appropriate inferences.

Ans: D Feedback: Inference is an integral part of doing research, and the use of strong methods yields evidence that supports the desired inferences. Qualitative researchers avoid using research control in their studies, and do not use the term “scientific merit”— these are associated with quantitative researchers. Bias is of concern in both quantitative and qualitative research.

Which quality criterion is especially important for trustworthiness in a qualitative study?

A) Triangulation B) Reflexivity C) Reliability D) Credibility Ans: D Feedback: Credibility is a particularly important aspect of a study’s trustworthiness. Credibility is achieved when the methods engender confidence in the truth of the data.

Triangulation, the use of multiple sources to draw conclusions about what constitutes the truth, is a strategy used to enhance credibility. Reflexivity is another strategy for strengthening credibility, referring to the process of reflecting critically on the self and of scrutinizing personal values that could affect data collection and interpretation.

Which can be a source of bias in both quantitative and qualitative studies?

A) The absence of triangulation B) Participants’ desire to present themselves in the best light C) The use of research control D) The use of reflexivity Ans: B Feedback: Participants may provide biased or distorted information to protect their privacy, or to “look good” (or “normal”) to research staff, both in quantitative and qualitative studies. The absence of triangulation does not in itself result in bias. Using reflexivity does not contribute to bias. The use of research control can in some cases obscure meaning in a qualitative study but is a tool used by quantitative researchers to reduce bias.

A) Sampling bias

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice B) Random bias C) Systematic bias D) Reflexive bias Ans: C Feedback: Random bias occurs when error is random and the distortions are as likely to bias values in one direction as the other for different people. Systematic bias, on the other hand, is consistent and distorts values in a single direction for all people, as is the case in this example. The term “reflexive bias” is not used in research.

Sampling bias concerns a flawed research sample that does not reflect the characteristics of the population and is not a term related to bias in measurements.

Patient age in this study would be considered: A) the independent variable.

B) the dependent variable.

C) a mediating variable.

D) a confounding variable.

Ans: D Feedback: Researchers seek to control confounding (or extraneous) variables—variables that are extraneous to the purpose of a specific study but that might contaminate the results because they may influence the dependent variable. In this case, patients’ age could be the actual influence on stress levels (the dependent or outcome variable), rather than gender (the independent variable of interest), if women in the sample were either older or younger than the men.

What is a general strategy that researchers use to control a confounding variable?

A) Holding it constant in the study B) Being reflexive about it C) Strengthening its validity D) Being “blinded” about its presence Ans: A Feedback: A general strategy that researchers use to control confounding (extraneous) variables is to hold them constant in the context of the study. The confounding variable must be handled in a manner that makes it unrelated to the independent variable or the outcome variable. Being “reflexive” about a confounder would not control it, nor would efforts to strengthen its validity. Being blinded about the presence of a confounder could worsen its influence in a study and would not control it.

What is the term for the strategy of withholding information from participants, interventionists, or other research staff to enhance objectivity?

A) Randomizing B) Generalizing C) Blinding D) Triangulation Ans: C Feedback: Blinding (or masking) is the term used for the strategy of withholding information, which is used in some studies to prevent biases stemming from people’s awareness or expectations. Objectivity can often be enhanced if participants or staff are not aware of who is getting special treatment, for example. Randomizing and triangulation are not strategies that involve withholding information. Generalizing is not a strategy, it is a criterion used to evaluate quantitative studies.

33. What mechanism is used by qualitative researchers to think critically about themselves and to scrutinize personal values that could affect their decisions and interpretations?

A) Reflexivity B) Triangulation C) Research control D) Randomness Ans: A Feedback: Reflexivity, the process of reflecting critically on the self and of scrutinizing personal values that could affect the conduct of the study and the interpretation of the data, is an important tool to guard against personal biases in qualitative research.

Research control and randomness are strategies used to enhance quality in quantitative studies, not in qualitative studies. Triangulation is a strategy, used by both quantitative and qualitative researchers, involving the use of multiple sources; it does not involve scrutiny of personal values.

The study violated the ethical principle of freedom from harm. The other answers are not ethical principles—they are strategies for addressing ethical principles. In any event, there would be no need for a Certificate of Confidentiality, and (despite their illness) participants would not be considered a vulnerable group.

one in which:

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice A) Informed consent cannot be obtained from all study participants.

B) Participants’ rights and the demands for rigorous research are in conflict.

C) Researchers knowingly violate ethical principles to achieve personal goals.

D) An ethical transgression is unavoidable.

Ans: B Feedback: Ethical dilemmas arise because the codes of ethical conduct sometimes constrain the researchers’ ability to undertake a study rigorously, pitting the benefits of new research evidence against the well-being of study participants. Ethical dilemmas are usually resolved by using less rigorous methods, not by knowingly committing ethical transgressions. Problems with obtaining informed consent do not create ethical dilemmas. Violating ethical principles to achieve personal goals is not an ethical dilemma—it is an ethical transgression.

A) Researchers’ obligation to fully disclose aspects of the research to participants B) Participants’ right to self-determination C) Researchers’ obligation to protect participants’ privacy D) Researchers’ obligation to maximize benefits and minimize harms Ans: D Feedback: Beneficence involves the requirement that researchers minimize harm and maximize benefits—often, maximizing the potential for benefits to others rather than to participants themselves. Participants’ rights to full disclosure and selfdetermination are aspects of the broad principle of “Respect for human dignity.”

Privacy protections fall under the broad principle of justice.

Which statement about the protection of study participants is true?

A) The principle of beneficence involves protecting participants from minimal risks.

B) The right to self-determination means that participants could decide that a friend could take their place in the study.

C) It would be ethically commendable to offer a stipend of US$250 to homeless veterans to participate in a study.

D) Qualitative researchers are often in a better position than quantitative researchers to “do good” (and not just avoid harm) with study participants.

Ans: D Feedback: In qualitative studies, researchers may develop a strong (and possibly semitherapeutic) relationship with participants through their in-depth discussions.

Beneficence involves avoiding harms for participants during the study but not protecting them from minimal risks. The right to self-determination does not mean that a participant could select a replacement to be in the sample. The offer of a large monetary stipend to a severely disadvantaged group could be considered mildly coercive and not ethically commendable.

federal research grant in the United States required to do?

A) Include women and minorities in their studies B) Disclose the benefits of the research to participants C) Offer participants a stipend for participation in the study D) Obtain informed consent from participants Ans: A Feedback: Researchers seeking funding from the U.S. National Institutes of Health are required to include women and minorities in studies to ensure their right to fair treatment. Disclosing the benefits of research is an aspect of participants’ right to full disclosure. Offering participants a stipend for their participation in the study is often used as an incentive to cooperate, but it is not a requirement for a federal grant.

participants?

A) Perform a risk/benefit assessment to evaluate the costs and the benefits of participation.

B) Keep painful procedure information from study participants until the study is completed.

C) Prevent psychological discomfort during the study.

D) Collect data from participants without their knowledge to prevent any possibility of stress or embarrassment.

Ans: A Feedback: One strategy that researchers can use to protect participants is to carefully assess the risks and the benefits of study participation. Keeping painful procedure information from study participants would violate their right to full disclosure and should not be done. Collecting data covertly is ethically questionable, as it also violates participants’ rights to full disclosure and self-determination. Researchers are not always able to prevent psychological discomfort during a study, but efforts to address such discomfort can be devised in identifying this as a potential risk.

study, which of the following might the researchers identify as a potential benefit?

A) Researchers’ opportunity to publish in a prestigious journal B) Participants’ opportunity to take some time off from work C) Students’ opportunity to gain research experience D) Knowledge gains that could benefit patients in the future Ans: D Feedback: The benefit to society, in terms of knowledge gains that can lead to future improvements, is often the key reason for doing health research. Researchers might succeed in getting good publications, participants might get some time off, and students might gain research experience, but these are not part of the equation in deciding whether a study is ethically justified.

Ans: D Feedback: Informed consent procedures provide prospective participants with the information they need to decide whether or not to participate in a study. Informed consent is needed even when researchers pay participants a stipend or when the risk/benefit ratio is low. Researchers in the United States may obtain a Certificate of Confidentiality to protect them against the forced disclosure of confidential information in a civil, criminal, administrative, or legislative proceeding. However, such a Certificate does not negate the need to obtain informed consent from study participants.

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice In qualitative studies, consent may need to be continually renegotiated with participants as the study evolves, through procedures called process consent.

about their health-promoting activities. The researcher considered the completion of the questionnaire as an indicator of the students’ permission to use their data.

This is an example of: A) process consent.

B) implied consent.

C) confidentiality.

D) deception.

Ans: B Feedback: Researchers often assume that a completed and returned questionnaire is evidence of implied consent—that is, that people willingly returned the questionnaire, and thus, they implied their permission to use their responses to the questionnaire as research data. Process consent involves ongoing renegotiating of consent, primarily in qualitative studies. The situation described does not concern confidentiality; the returned questionnaire may or may not have information that could divulge the person’s identity.

to specific participants?

A) Confidentiality B) Anonymity C) Informed consent D) Covert data collection Ans: B Feedback: Privacy can be maintained through anonymity (wherein not even researchers know participants’ identities) or through formal confidentiality procedures. Formal confidentiality procedures involve a pledge to safeguard the information that participants provide, but the researcher can link participants to their data. Informed consent procedures provide prospective participants with the information needed to make a reasoned decision about participation, but they are not confidentiality procedures.

Which of the following constitutes an ethical transgression?

A) Breaching confidentiality B) Not performing a risk/benefit assessment C) Not collecting data anonymously D) Failing to obtain a Certificate of Confidentiality Ans: A Feedback: Study participants have the right to expect that their privacy is protected by assurances of confidentiality; it is a serious ethical transgression to have a breach in the confidentiality of participants’ data. Performing a risk/benefit assessment is desirable, but not performing such an assessment does not constitute an ethical transgression. In many studies, anonymity is not possible, but this does not necessarily create ethical problems. Relatively few studies gather sensitive data that require a Certificate of Confidentiality.

What action could a researcher take to increase the confidentiality of study participants?

A) Avoid collecting any of their identifying information.

B) Avoid introducing participants to other participants in the study.

C) Maintain all identifying information on computer files rather than in manual files.

D) Destroy all identifying information within 3 years of the end of the study.

Ans: A Feedback: The confidentiality of study participants is increased when no identifying information is obtained, although this is not always possible because it limits researchers’ ability to communicate with participants (e.g., to share study results with them). Study participants are rarely introduced to other participants, but a simple introduction need not undermine the confidentiality of the data provided.

Confidentiality is not necessarily increased by maintaining information on computer files or by destroying information at a certain time after the study has ended.

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice Feedback: To avoid the forced disclosure of sensitive research information (e.g., through a court order), researchers in the United States can apply for a Certificate of Confidentiality from the National Institutes of Health. Although sensitive information might be divulged in virtually any study (e.g., an incidence of child abuse among women with postpartum depression, elder abuse among caregivers of people with Alzheimer’s disease), a study of heroin abuse would almost surely reveal compromising information for many study participants because heroin addiction is the focus of the study.

Which type of research communication does the following represent? “For the thousands of patients on chemotherapy, nausea and vomiting are common side effects. To date, interventions have been only moderately successful in reducing these effects. New interventions that can reduce or prevent these side effects need to be identified to improve the quality of life of these patients.”

A) A hypothesis B) A research question C) A statement of purpose D) A portion of a problem statement Ans: D Feedback: Problem statements articulate the nature, severity, and scope of a problem, and indicate what information is lacking to solve the problem. The statement in question is not a statement of purpose, a hypothesis, or a research question. A statement of purpose summarizes the overall goal of a study and identifies the key variables and the population. A hypothesis is a statement of a predicted relationship between two or more variables. A research question is the specific query researchers want to answer in addressing the research problem.

B) portion of a problem statement.

C) statement of purpose.

D) hypothesis.

Ans: C Feedback: A statement of purpose for a qualitative study, which summarizes the overall study goal, identifies the key concept or phenomena (here, living with a colostomy) and the study group or population (patients who had surgery for colon cancer). The statement in question is not a hypothesis, a research question, or a portion of a problem statement. Research questions are the specific queries researchers want to answer in addressing the research problem—and the statement under consideration is not worded as a query. A problem statement articulates the nature, context, and significance of a problem to be studied. A hypothesis states predicted relationships between two or more variables, and qualitative studies do not test hypotheses.

In a statement of purpose, a researcher indicates that the goal of the study is to understand the lived experiences of family members caring for a terminally ill child with cancer. What type of study is this?

A) Ethnographic B) Grounded theory C) Phenomenological D) Experimental Ans: C Feedback: Phenomenology is concerned with the lived experiences of humans. Terms often associated with this tradition include experience, lived experience, meaning, and essence. The grounded theory tradition seeks to describe and understand the key social psychological processes that occur in a social setting, not lived experiences.

Ethnographic studies focus on the patterns and lifeways of a culture. The purpose statement in question is not for an experimental (quantitative) study.

Which of the following sentences is most likely to be a statement of purpose for a grounded theory study?

A) The aim is to describe the cultural behaviors of immigrant women going through menopause.

B) The aim is to explore the lived experience of immigrant women going through menopause.

C) The aim is to understand the process by which immigrant women adapt to transitions during menopause.

D) The aim is to describe the percentage of immigrant women who go through menopause and seek health care advice.

Ans:C Feedback: Grounded theory studies focus on processes and social interactions, such as major life transitions and adaptation to them. Cultural behaviors are studied in ethnographies, and phenomenologists focus on lived experiences. A quantitative study, rather than a qualitative one, would seek to learn the percentage of menopausal immigrant women who seek health care advice.

C) In a population, what is the relationship between the IV and the DV? D) In a population, what is the frequency of occurrence of the DV? Ans: A Feedback: Etiology/harm questions concern factors that cause or contribute to the risk of a health problem or a disease. The general question about the relationship between the IV and DV is the most generic question template—not specific to Etiology/harm questions. The question template that has an intervention as the IV is for a Therapy question. A question about frequency of occurrence of a research variable is simply descriptive, not about relationships between variables.

D) Qualitative researchers do not develop hypotheses prior to data collection.

Ans: D Feedback:

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Quantitative researchers make specific predictions about relationships between variables and then test those predictions, but qualitative researchers want to learn from participants without having a priori conjectures. Deduction (not induction) is the process of deriving hypotheses from general propositions, such as theories.

Hypotheses involve two variables at a minimum—the independent and the dependent variable. Researchers rarely state their hypotheses in the null form in a research report; the null hypothesis is used primarily as the basis for statistical tests.

22. Here is a research hypothesis: “Women with high levels of prenatal physical activity have infants of lower birth weight than sedentary women.” What is an alternative wording for this hypothesis?

A) Women’s levels of prenatal physical activity are unrelated to their infants’ weight at birth.

B) The greater the amount of maternal prenatal physical activity, the lower the infant’s birth weight.

C) There is a correlation between a woman’s prenatal physical activity and the birth weight of her infant.

D) Women who are sedentary during their pregnancies are as likely as physically active women to have infants that are of below-average weight.

Ans:B Feedback: The hypothesis in question is a directional hypothesis, predicting that women who are physically active during their pregnancies have infants with lower birth weight than women who are sedentary. The wording “The greater the amount of maternal prenatal physical activity, the lower the infant’s birth weight” also states a directional hypothesis. The other hypotheses are either null (“are unrelated” and “are as likely”) or nondirectional (“There is a correlation . . . ”).

D) Among patients with Parkinson’s disease, an outdoor fall is more likely to result in injury than an indoor fall.

Ans: A Feedback:

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

The null hypothesis states that there is no relationship between the independent variable (a person’s location—indoors versus outdoors) and the dependent variable (a fall); it is this hypothesis that would be subjected to statistical testing. All of the other answers are directional research hypotheses with a specific prediction.

Format: Multiple Choice Chapter: 5 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Analyze Difficulty: Difficult Integrated Process: Nursing Process Objective: 03 Page and Header: 84, Wording of Hypotheses 24. A null hypothesis is used: A) to avoid the appearance of bias.

B) when a researcher is uncertain what the findings will be.

C) in testing hypotheses statistically.

D) when the researcher predicts that the relationship between variables is complex.

Ans: C Feedback: The null hypothesis is stated in the form that is subjected to statistical testing—the researchers use statistics to assess whether the prediction of no relationship can be rejected. A null hypothesis is seldom stated in a research report, and so null hypotheses are not used to avoid the appearance of bias. Researchers are never certain about predicted relationships, but hypotheses represent their “best guess,” taking into consideration theory or other research. The complexity of a hypothesis concerns how many variables are involved in the prediction, not whether a hypothesis is stated in null form.

Here is a research hypothesis: “The greater the number of hours of watching television weekly, the greater a person’s body mass index (BMI).” Which wording for this hypothesis would make it nondirectional?

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

A) There is no relationship between weekly hours of television watching and a person’s BMI. B) Weekly hours of television watching are related to a person’s BMI. C) People who watch more television weekly are more likely to have a high BMI than those who do not.

D) Body mass index is higher among those who watch a lot of television.

Ans: B Feedback: Nondirectional hypotheses predict that two variables are related but do not predict whether higher or lower values on the independent variable (here, of TV watching) are associated with higher or lower values of the dependent variable (here, BMI).

The option that states “There is no relationship” is a null hypothesis. The other two options are directional—they predict that more TV watching is associated with higher BMI.

What type of hypothesis is represented by the following prediction? “The fewer social supports an older person has, the more likely the individual will be institutionalized when experiencing a health problem.”

A) Null B) Complex C) Nondirectional D) Directional Ans: D Feedback: Directional hypotheses predict the direction of a relationship, and in this case, there is an explicit prediction about how social supports and institutionalization are related. Nondirectional hypotheses predict the existence of relationships, not their direction. Null hypotheses, which express the absence of a relationship, are the hypotheses subjected to statistical testing.

C) School-aged boys differ from school-aged girls in attitudes toward physical activity.

D) A person’s health-related quality of life is related to that person’s income and marital status.

Ans: D Feedback: A complex hypothesis involves three or more variables.

A) Journal articles describing a quantitative study always state the researcher’s hypotheses.

B) Hypotheses are tested in qualitative study through an inductive process.

C) Hypotheses prove the existence of relationships between two or more variables.

D) Stating upfront hypotheses can reduce the possibility that spurious results will be misinterpreted.

Ans: D Feedback: Without stating their hypotheses upfront, researchers can readily interpret almost any result; hypotheses promote critical thinking and can lead to more thoughtful interpretations of study results. Researchers do not, however, always state their hypotheses, even when they have them. Hypotheses (and the tests of hypotheses) do not prove that variables are related.

A) The references are restricted to those published in nursing journals.

B) The references are restricted to those published after 2010.

C) There is an emphasis on interpretation and opinions.

D) The review is reproducible, with clear decision rules.

Ans: D Feedback: Research literature reviews should be systematic, with explicit guidelines about which studies to include; in this fashion, another diligent reviewer would be able to apply the same decision rules and come to similar conclusions about the state of evidence on the topic. High-quality reviews should include both very recent studies as well as older ones, and they can (depending on the topic) rely on studies in disciplines other than nursing.

A) Searching for articles that summarize prior research in a bibliographic database B) Reading abstracts to determine whether the article is pertinent to the topic C) Tracking down studies cited in the reference list of a relevant research report D) Using a pivotal study to search forward to subsequent studies that cited it Ans: C Feedback: The ancestry approach (also called “footnote chasing”) involves using citations from relevant studies to track down earlier research on which the studies are based (the “ancestors”). Other strategies for finding studies include the use of bibliographic databases and using a pivotal study to “search forward.” Reading abstracts, although necessary in conducting a literature review, is not a search strategy.

One of several strategies for locating completed studies on a research question is called the descendancy approach. What does this approach entail?

A) Searching for articles that summarize prior research in a bibliographic database B) Reading abstracts to determine whether the article is pertinent to the topic C) Tracking down earlier studies cited in the reference list of a relevant research report D) Using a pivotal study to search forward to subsequent studies that cited it Ans: D Feedback: The descendancy approach involves identifying a key early study and then using citation indexes to locate later studies that cite the original study. Other strategies for finding studies include the use of bibliographic databases and tracking down earlier studies cited in a reference list of a report (“footnote chasing”). Reading abstracts, although necessary in conducting a literature review, is not a search strategy.

In conducting a subject search in an electronic database, the researcher would most likely initiate the search by typing which of the following into the data field?

A) An author’s name B) The research question C) A keyword D) An ancestor or descendant Ans: C Feedback: Most searches involve undertaking a subject search, most often by inserting a keyword into the search field. You could conduct a search by entering an author’s name, but this would not be a subject search. Searchers do not enter an entire research question but rather the keywords than embody key elements of the question, such as key research variables or the population. An “ancestor” or “descendant” is a previously conducted study; neither is used as entries in the search field for a bibliographic subject search.

In electronic literature searches, bibliographic software usually has the capability of locating relevant references when the researcher does not know the precise subject codes used in the database. This software feature is called: A) searching.

B) mapping.

C) expanding.

D) delimiting.

Ans: B

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Feedback: Mapping is a “translation” feature that allows people to search for topics using their own keywords rather than needing to use a term that is exactly the same as a subject code in the database. Searching is a generic activity. Expanding a search involves placing fewer restrictions on a search, and delimiting can be used to restrict a search for certain features; these features are not a capability relating to translating keywords to subject codes.

What of the following would be a reasonable keyword for the question “Among patients with cancer, are men or women more likely to comply with dietary guidance?”?

A) Male B) Female C) Masculinity D) Gender Ans: D Feedback: In the research question, the independent variable is gender—that is, the question is whether gender is an influence on patients’ compliance with dietary guidance.

“Male” and “female” are not variables—they are two possible categories for the variable gender. “Masculinity” is not a factor that was under study in this example.

Which Boolean operator delimits a search in a bibliographic database?

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

A) BUT B) AND C) OR D) IF Ans: B Feedback: The Boolean operator AND delimits a search—both terms on either side of the “AND” must be present in the search fields of articles that are retrieved. Another Boolean operator is OR. BUT and IF are not Boolean operators.

Which Boolean operator expands a search in a bibliographic database?

A) OR B) AND C) IF D) NOT Ans: A Feedback: The Boolean operator OR expands a search—either of the terms on the two sides of the “OR” must be present in the search fields of articles that are retrieved. Two other Boolean operators are AND and NOT. IF is not a Boolean operator.

If a person entered “foli*” into the search field for an electronic bibliographic search, what would happen?

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

A) There would be an error message.

B) The search would retrieve all citations that have “folic” in the text fields of records.

C) The search would retrieve only citations having an author whose last name was Foli.

D) The search would turn on the mapping capabilities of the database software.

Ans: B Feedback: In electronic searches, the truncation symbol—in most cases an asterisk—expands a search term to include all forms of a root. In this example, the root is “foli,” and so the search would retrieve all records with such words as folic, foliate, folio, and folinic in text fields. The search would also retrieve papers written by authors with the name “Foli,” but such papers would not be the only records identified. The use of an asterisk would not result in an error message, but its use turns off mapping capabilities in some databases.

With regard to a search for quantitative studies on a research question in a bibliographic database, which statement is most accurate?

A) The best place to begin a search is to use a search engine such as Yahoo or Bing.

B) The primary keyword to start the search typically would be the population of interest.

C) The primary keywords to start the search typically would be the independent and dependent variables.

D) Subject searches and textword searches yield the same results.

Ans: C Feedback:

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

For quantitative studies, the most productive keywords are usually the independent or dependent variables (i.e., the “I,” “C,” and “O” of the PICO components).

Searching for a specific population might limit the records retrieved too narrowly or expand it too broadly. Internet search engines such as Yahoo and Bing are not the best places to search for primary research evidence. Subject searches involve searches for citations that are specifically coded in a certain manner, and textword searches retrieve records with the designated words in their fields of text (e.g., in the abstract).

Format: Multiple Choice Chapter: 6 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Analyze Difficulty: Moderate Integrated Process: Teaching/Learning Objective: 02 Page and Header: 93, Getting Started with an Electronic Search 20. Which statement is true?

A) A search for brain tumor and “brain tumor” in a bibliographic database would likely yield different results.

B) A search for brain tumor would yield the same results in any bibliographic database.

C) A search for brain OR tumor would yield fewer results than brain AND tumor.

D) A search for brain tumor, because there are two words, would turn off the mapping feature in most databases.

Ans: A Feedback: Placing quotation marks around a phrase restricts the search to records where the words in quotes are used together, so the use of quotes would result in fewer (but perhaps more relevant) records. The use of the Boolean operator “OR” expands a search, whereas “AND” restricts a search. The use of a phrase, rather than a single word, does not turn off mapping capabilities.

21. The electronic database that focuses on the nursing and allied health literature is: A) CINAHL. B) EMBASE. C) Web of Knowledge.

D) MEDLINE. Ans: A Feedback: The CINAHL (Cumulative Index to Nursing and Allied Health Literature) database specifically focuses on literature of relevance to nurses and those in allied health professions. Other useful bibliographic databases include MEDLINE, Web of Knowledge, and EMBASE (the Excerpta Medica database), but these are all useful to broad audiences of health care professionals.

A) The CINAHL database includes only journal articles.

B) The CINAHL database includes about 26 million records.

C) The CINAHL database uses the controlled vocabulary called MeSH to index entries.

D) Subject headings in CINAHL include substantive topics and methodologic topics.

Ans: D Feedback: CINAHL covers references to hundreds of nursing and allied health journals as well as to books, book chapters, and dissertations. Records in the database are coded for both substantive topics (e.g., dementia) and methodologic topics (e.g., experimental studies). CINAHL contains more than 6 million records but not 26 million. It is MEDLINE, not CINAHL, that uses the controlled vocabulary called MeSH to index entries.

B) PubMed provides access to MEDLINE free of charge to Internet users.

C) PubMed does not allow users to find “Similar articles” for a previously identified record in MEDLINE. D) MEDLINE entries are translated into more than 20 languages.

Ans: B Feedback: MEDLINE can be accessed for free on the Internet through the PubMed website and does not require a paid subscription. After you have found a study that is a good exemplar of what you are looking for in MEDLINE, you can identify “similar articles” in the database in a panel of the screen for each record.

Which does the MEDLINE database use to provide a consistent way to retrieve information for which authors might have used different terms?

A) Textwords B) MeSH C) Boolean operators D) Scopus reviews Ans: B Feedback: MeSH (Medical Subject Headings) is the controlled vocabulary used in MEDLINE; it provides a means of retrieving records that may use different terminology for the same concepts. A textword search looks for keywords in the text fields of the records (e.g., in the title and abstract). Boolean operators (such as “AND” and “OR”) can be used to expand or restrict a search and is not unique to MEDLINE. Scopus is an alternative bibliographic database.

A) GS is accessed by paying an annual subscription fee.

B) GS is unlike other bibliographic databases in that Boolean operators cannot be used.

C) The GS database includes articles in journals in all disciplines as well as books and technical reports.

D) GS is the most widely respected bibliographic search engine for health research.

Ans: C

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Feedback: The Google Scholar database includes articles published in professional journals in a wide range of disciplines (not just health-related) as well as books and technical reports. Similar to MEDLINE and CINAHL, GS permits the use of Boolean operators.

It is available free of charge over the Internet. Although GS has been gaining in popularity in the field of medicine, GS remains somewhat controversial in academic circles.

Which of the following statements about open-access journal articles is true?

A) They can be downloaded for free over the Internet.

B) They are available for free to users from institutions that have paid a subscription fee.

C) They can be retrieved only by using the resource called Research Gate.

D) They are called “open” because they have not been peer-reviewed.

Ans: A Feedback: Open-access journal articles can be downloaded free of charge by anyone with an Internet connection. Open-access journals do not involve a subscription fee.

Research Gate is a resource for retrieving an article (often by communicating with researchers/authors to request a copy), but open-access articles do not require using Research Gate. Open-access articles are usually peer-reviewed.

The researcher has identified 66 potential references for a literature review through electronic database searches and a descendancy search. What would most likely be the next step?

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

A) Coding the characteristics of each study B) Entering information onto a literature review protocol C) Reading each article in detail D) Reviewing the abstracts for relevance Ans: D Feedback: After the initial identification of potential references, the researcher would need to screen the articles to make sure they are truly relevant to the research question.

Reading all articles in their entirety would allow the researcher to evaluate relevance but reviewing the abstracts first would be more efficient. Researchers sometimes enter information from each reference onto a protocol or code the attributes of the relevant studies, but these would be later steps, completed after the references are screened for relevance.

What is the primary purpose of documenting steps in the literature retrieval process?

A) To ensure approval by the Institutional Review Board (IRB) B) To minimize the risk of duplication of effort C) To provide a list of useful search words D) To simplify the preparation of the reference list Ans: B Feedback: Documentation helps reviewers to conduct a more efficient search by preventing unintended duplication and also helps them to assess what other search strategies need to be tried. Although documentation does provide a list of useful search words and may ultimately simplify the preparation of the reference list, neither of these is the primary purpose. Documentation is unrelated to approvals by an Institutional Review Board (IRB), who would seldom be concerned with the literature review aspects of a study.

Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Analyze Difficulty: Moderate Integrated Process: Nursing Process Objective: 04 Page and Header: 98, Appraising Studies for a Review 30. In evaluating primary studies for a literature review, what is the key question that a reviewer needs to consider?

A) Was the research question in the study appropriate?

B) Did the authors include an adequate literature review in their research report?

C) Did the authors cite appropriately from the previously published literature related to the problem under study?

D) To what extent are the study findings based on sound research methods and thus reflect the true state of affairs?

Ans: D Feedback: In literature reviews, an assessment of each study must be made with an eye to answering a broad question: To what extent do the findings reflect the truth (the true state of affairs)—that is, do flaws in the methods used undermine the believability of the evidence? A reviewer would not critique the appropriateness of the research question and would not focus primarily on the quality of the references or the literature review in each article under review because flaws are unlikely to have a bearing on the quality of the study’s evidence.

A) Substantive B) Ethical C) Methodologic D) Generalizability/transferability Ans: B

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Feedback: Reviewers would not look for ethical themes in the primary studies—unless the focus of the research was on research ethics, which would then make ethics a substantive issue. Substantive themes—the pattern of evidence for the research question under review—are the most commonly analyzed themes, but reviewers might examine methodologic themes (Which methods have been used to address the research question?) and generalizability/transferability themes (To which populations does the evidence apply?)

Which of the following statements about a written literature review is not true?

A) In a written review, it is useful to include a lot of direct quotes from the primary studies in the review.

B) In a review, studies with similar findings can often be summarized together (e.g., “Several studies have found ...... ”).

C) Literature reviews in the introduction of a research report usually conclude with a summary of why existing evidence supports the need for a new study.

D) Inconsistencies in the research evidence should be reported in the review and analyzed objectively.

Ans: A Feedback: The research evidence should be summarized in the reviewer’s own words rather than stringing together quotes from the primary studies. It is true that similar findings in several primary studies can often be summarized together. If the review is written as part of the introduction for an article reporting a new study, the review should conclude with a summary of how the evidence demonstrates the need for the new research. In an unbiased review, inconsistencies are reportedly candidly and analyzed objectively.

C) Research has consistently found that infants’ sleeping position is related to the risk of sudden infant death syndrome.

D) Nurses and physicians struggle with the decision about whether to work in environments where abortion services are offered.

Ans: C Feedback: Written research reviews should provide an objective, organized synthesis of current research findings (evidence) on a research question and should use language that suggests the absence of bias (e.g., “studies have found . . . ”). The sentence “The HIV epidemic has been the cause of considerable anxiety in the gay community” does not summarize evidence, nor does the sentence “Nurses and physicians struggle with the decision about whether to work in environments where abortion services are offered.” Studies cannot prove that men have more difficulty coping with widowhood than women.

B) descriptive theory.

C) grounded theory.

D) conceptual model.

Ans: A Feedback: As classically defined, a theory is an abstract generalization that explains how phenomena are interrelated. Descriptive theory thoroughly describes a phenomenon and does not involve interrelationships. Conceptual models involve loose organization among abstractions, but they do not involve a structured system of propositions that explain relationships among phenomena. A grounded theory, which is developed in the qualitative grounded theory tradition, does not explain interrelationships among phenomena.

A theory is an abstract generalization that purports to systematically explain relationships among phenomena, but a theory does not offer proof of these relationships. Theories are elaborated with words, but some theories can be summarized graphically in a schematic model. Theories do not provide guidance for testing hypotheses deduced from theory—researchers’ ingenuity must be used to deduce hypotheses and to develop research methods and analytic approaches for testing hypotheses.

Theories differ in their level of generality and abstraction. What term is used to designate a theory that attempts to explain specific phenomena, such as stress, adaptation, and unpleasant symptoms?

A) Descriptive theory B) Grand theory C) Middle-range theory D) Reinforcement theory Ans: C Feedback: Middle-range theories attempt to explain specific phenomena. In nursing, there are hundreds of examples of middle-range theories—such as middle-range theories of stress, comfort, health promotion, and unpleasant symptoms. Descriptive theories are not “explanatory” but may be a precursor to an explanatory middle-range theory. Grand theories purport to describe and explain large segments of the human experience.

A) They both use concepts as their building blocks.

B) They both involve a logically interrelated system of propositions.

C) They both can be either descriptive or explanatory.

D) They both can be classified as either grand or middle-range.

Ans: A Feedback: The basic components of both theories and conceptual models are concepts. Only traditional theories involve a logically interrelated system of propositions. Neither traditional theories nor conceptual models are purely descriptive—they involve relationships among phenomena. Conceptual models are not usually classified as grand; conceptual models more closely align with middle-range theories of specific phenomena (e.g., health promotion).

B) All nursing studies have a framework.

C) Nursing intervention studies do not require a conceptual model or theory.

D) Grand theories are a greater source of inspiration to researchers than middlerange theories.

Ans: B Feedback: All nursing studies have a framework—that is, a conceptual rationale—although the framework is not always made explicit. Not all studies are based on a theory or a conceptual model, but many intervention studies have a strong conceptual or theoretical basis. Middle-range theories are more likely than grand theories to inspire research about a phenomenon of interest.

A) develop a conceptual map.

B) search for a grand theory.

C) undertake a concept analysis.

D) undertake a deductive analysis.

Ans: C Feedback: A concept analysis can be useful for clarifying conceptual definitions of phenomena under study. Conceptual maps and grand theories would not be used to develop conceptual definitions of key concepts. Deductive analyses might lead to hypotheses to be tested but not to conceptual definitions.

A) They are invented or created, not discovered.

B) For nursing studies, they need to be borrowed from other disciplines.

C) They both contain a set of logically interrelated propositions.

D) They both can be proved or disproved through research.

Ans: A Feedback: Theories and conceptual models are invented or created—they are not “out there” awaiting discovery. A theory, but not a conceptual model, consists of concepts and a set of propositions that form a logically interrelated system. Nurses have developed theories and conceptual models and do not rely exclusively on those borrowed from other disciplines. Research cannot “prove” or “disprove” the validity of theories or conceptual models, but findings from research can lend support to them.

A) Systematic reviews of research findings are based on theories.

B) The relationship between theory and research is reciprocal.

C) Theories are proved when there is sufficient research evidence confirming them.

D) Theories, once there is sufficient research evidence, are considered fixed and enduring.

Ans: B Feedback: Theory and research have a reciprocal relationship. Theories are built inductively from research findings, and the theory in turn is tested by deducing research hypotheses that are then subjected to research inquiry. Systematic reviews of research are not based on theories. Theories are invented and are never proved.

Because theories cannot be “proved,” they are not fixed or “enduring.” Theories often evolve and are discarded as new research evidence comes to light or, as sometimes happens, there are changes in social or cultural values (e.g., Freudian theory came to be disputed with the rise of feminism).

The Health Promotion Model would best be described as which type of theory?

A) A descriptive theory B) A grand theory C) A grounded theory D) A middle-range theory Ans: D Feedback: Pender’s Health Promotion Model (HPM) is an example of a widely used middlerange theory (not a grand theory) developed by a nurse; middle-range theories are specific to certain phenomena, such as health-promoting behavior. Descriptive theory thoroughly describes a phenomenon, and the HPM goes beyond description.

Some qualitative researchers seek to develop grounded theories, explanations to account for phenomena that are grounded in actual observations—but the HPM is not a grounded theory.

A) Mishel’s Uncertainty in Illness Theory

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

B) Beck’s Theory of Postpartum Depression C) Pender’s Health Promotion Model D) Kolcaba’s Comfort Theory Ans: A Feedback: Mishel’s Uncertainty in Illness Theory focuses on uncertainty—the inability of a person to determine the meaning of illness-related events. Uncertainty and interpreting the meaning of illness-related events is not the central construct in the other middle-range theories, such as Beck’s Theory of Postpartum Depression, Pender’s Health Promotion Model, or Kolcaba’s Comfort Theory.

B) the Theory of Planned Behavior.

C) Social Cognitive Theory.

D) the Uncertainty in Illness Theory.

Ans: C Feedback: Bandura’s Social Cognitive Theory, which is sometimes called self-efficacy theory, offers an explanation of human behavior using the concepts of self-efficacy, outcome expectations, and incentives. The other three response options—Mishel’s Uncertainty in Illness Theory, Ajzen’s Theory of Planned Behavior, and Prochaska’s Transtheoretical Model—do not incorporate the concept of self-efficacy into their models/theories.

A) Stress and coping B) Stages of change C) Outcome expectations D) Health beliefs Ans: B Feedback: Prochaska and colleagues’ Transtheoretical Model has “stages of change” as its core construct, around which other dimensions are organized. The Transtheoretical Model does not focus on stress and coping, outcome expectations, or health beliefs—these are core constructs in other theories or models that nurse researchers have used.

Which of the following is a key construct in several health-related models and theories and is often conceptualized as an important mediating variable in behavior change interventions?

A) Health beliefs B) Motivational readiness C) Adaptation D) Self-efficacy Ans: D Feedback: Self-efficacy, a construct in Bandura’s Social Cognitive Theory, has been identified as a key mediating variable in several theories, such as Pender’s Health Promotion Model. Self-efficacy enhancement is often an intermediate goal in interventions designed to change people’s health-related behaviors. Health beliefs, adaptation, and motivational readiness are constructs in health-relevant models and theories but have not been found as broadly useful as self-efficacy.

Which is a prominent theoretical underpinning of grounded theory?

A) Substantive theory B) Ideational theory C) Materialistic theory D) Symbolic interactionism Ans: D Feedback: The most prominent theoretical system in grounded theory is symbolic interaction (or interactionism), which concerns how meaning arises in the context of human interactions. Grounded theory research may develop substantive theories (about specific phenomena), but they are not the broad theoretical underpinning of grounded theory studies. Ideational theory and materialistic theory are relevant in ethnography, not in grounded theory.

Format: Multiple Choice Chapter: 7 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Understand Difficulty: Moderate Integrated Process: Communication and Documentation Objective: 03 Page and Header: 110, Theories and Qualitative Research 27. Which of the following is a type of cultural theory that can help to shape an ethnographic inquiry?

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

A) Grand theories B) Materialistic theories C) Substantive theories D) Grounded theories Ans: B Feedback: Ethnographers adopt one of two cultural theories: ideational theories, which suggest that cultural conditions and adaptation stem from mental activity and ideas, or materialistic theories, which view material conditions as the source of cultural development. Substantive theory is a conceptualization of a specific phenomenon under study and does not help to shape ethnographic research.

Grounded theory is a qualitative research tradition and is not related to ethnographic theories. “Grand theory” is a theory that purports to explain large segments of human experience and is not an ethnographic term.

Which of the following statements about using theory in quantitative studies is true?

A) Theory testing relies on inductive processes.

B) Intervention studies do not involve testing hypotheses deduced from a theory.

C) Fitting a research question to a theory after the fact is often a productive approach.

D) Theories are often not tested directly in a study but rather are used as an organizing structure.

Ans: D Feedback: Many researchers use theories and models as an organizational or interpretive tool rather than testing the theory directly. Intervention studies are increasingly theorybased. Testing a theory involves a deductive process, not an inductive one— hypotheses that can be tested with research data are deduced from the theoretical propositions. It is rarely productive to attempt to create an after-the-fact linkage between a research question and a theory or model.

Which of the following statements about appraising frameworks in research reports is not true?

A) In a critical appraisal of quantitative studies, one question to ask is whether stated hypotheses truly flow from the theory that was specified.

B) Quantitative studies that do not mention a theoretical framework are inherently flawed and cannot yield useful evidence.

C) Some researchers present a theoretical rationale in their reports that seems contrived.

D) In grounded theory studies, one question to ask concerns whether the raw data (e.g., excerpts from interviews) provides convincing evidence of the grounded theory.

Ans: B Feedback: Although many studies benefit from an explicit theoretical or conceptual framework, some research questions are so pragmatic that the absence of an explicit framework would not be considered a flaw. Ideally, hypotheses would flow from the theory or model that was stated as the inspiration, and it is important to examine whether this is true in critically appraising a study. Another important question in grounded theory studies is whether sufficient supporting evidence in support of the grounded theory has been provided. It is true that sometimes the connection between a theoy rand the research question seems contrived and artificial.

B) whether there will be an intervention.

C) what types of comparisons will be made.

D) how many times data will be collected.

Ans: A Feedback: The research design is the overall plan for answering research questions. In quantitative studies, the design incorporates decisions about whether there will be an intervention, what type of comparisons will be made, and how many times data will be collected.

This strategy is an example of: A) randomization.

B) attrition.

C) crossing over.

D) blinding.

Ans: D

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Feedback: Blinding involves concealing information from participants (here, the parents) and research staff (those administering the sucrose or sterile water) to enhance objectivity and minimize the risk of bias. Randomization is a strategy designed to control confounding variables, as is the use of a crossover design. There is no indication that these strategies were used in this example.

When researchers withhold information from the people collecting research data (e.g., information about who received an intervention and who did not), the researchers are taking steps to minimize which type of bias?

A) Selection bias B) Attrition bias C) Expectation bias D) History bias Ans: C Feedback: Blinding (masking) involves concealing information from participants and staff to minimize the risk of biases stemming from people’s expectations about the study outcomes. Research staff’s expectations can result in changes in what they see, what they hear, and what they say to participants. Selection bias (or selection threat) refers to preexisting differences between groups being compared. Attrition bias results from the differential loss of participants from study groups. A history bias occurs when an external event co-occurs with an intervention and obscures the intervention’s effect.

B) where the study will take place.

C) how confounding variables will be controlled.

D) when and how often the data will be collected.

Ans: A Feedback: A counterfactual is what would happen if people are simultaneously exposed and not exposed to an intervention. When evaluating an intervention, researchers must select a comparison strategy to represent the “not exposed” situation. Other design decisions concern where to conduct the study, how confounders will be controlled, and how often data will be collected, but these are unrelated to designing a suitable counterfactual.

A) From whom should information about the design be withheld?

B) When will the research data be collected?

C) What factors, other than the independent variable, could affect the outcome?

D) Where and how often will data collection occur?

Ans: C Feedback: When developing a plan to control confounding variables, researchers often need to answer the question “What other variables could influence the outcomes?” The other options, which all relate to important design decisions, are not relevant to the issue of controlling confounding variables.

A) The absence of ambiguity about how outcomes will be measured B) The absence of ambiguity about which variable occurred first C) The ability to randomly assign study participants to groups D) The ability to blind study participants and research staff Ans: B Feedback: A key criterion for establishing causality is ensuring that the cause (the independent variable) preceded the effect (the outcome). A causal inference does not depend on blinding or on how outcomes will be measured. Randomization is a strategy for facilitating causal inference, but it is not a criterion for the inference.

B) deterministic.

C) prognostic.

D) counterfactual.

An important function of research design strategies in a quantitative study is to exert control over: A) outcome variables.

B) mediating variables.

C) carryover variables.

D) confounding variables.

Ans: D Feedback: Confounding variables can obscure the relationship between the independent and dependent variables; they need to be controlled to enhance causal inferences.

Outcome variables and mediating variables are variables in which researchers are interested and do not need to be controlled. There is no such thing as a “carryover variable.”

A hypothetical condition embodying what would have happened to people if they were simultaneously exposed and not exposed to a causal factor is: A) a cause.

B) an effect.

C) a confounder.

D) a counterfactual.

Ans: D Feedback:

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

In a research context, a counterfactual is what would have happened to the same people exposed and not exposed simultaneously to a causal factor. A counterfactual can never be realized, but it is a good model to keep in mind in designing a study to address cause-probing questions. An effect is the difference between what actually did happen with the exposure (the cause) and what would have happened without it. A confounder is a variable or influence that is extraneous to the research question and that needs to be controlled.

There are three well-established criteria for inferring a causal relationship, attributed to John Stuart Mill. Which is one of those criteria?

A) A cause and effect must occur simultaneously.

B) A counterfactual must be known and controlled for in the research design.

C) The relationship between the cause and the effect cannot be explained as being caused by a third factor.

D) The relationship between the cause and the effect must be deterministic.

Ans: C Feedback: One of the criteria for a causal relationship is that the effect cannot be caused by a third variable, i.e., a confounder. Confounding variables must be controlled and ruled out. A cause must precede the effect (not occur simultaneously).

Counterfactuals are not controlled, confounders are. Causes are almost always probabilistic, not deterministic (i.e., they increase the likelihood that the effect will occur).

The use of randomization for assigning participants to conditions eliminates: A) systematic bias.

B) ethical problems.

C) the need for a control group.

D) the need for manipulation.

Ans: A Feedback: Random assignment is done using methods that give every participant an equal chance of being in any group, such as by flipping a coin. In this fashion, the risk of systematic bias is eliminated. Randomization is the most reliable method for equating groups on all characteristics that could affect study outcomes—that is, for approximating the ideal but impossible counterfactual. Randomization does not eliminate ethical problems, the need for a control group, or the need to manipulate the independent variable.

B) Grouping participants with similar features together is the best way to achieve random assignment.

C) The assignment of participants to different conditions at random is a signature of a true experiment.

D) Recruiting participants from different neighborhoods results in random assignment.

Ans: C Feedback: A true experiment requires randomly assigning participants to different groups or conditions; randomization is a signature of a true experimental design. Random sampling is a method of selecting people for a study and is not used to accomplish randomization to groups. Grouping participants with similar features and recruiting participants from different neighborhoods are not random methods; they are flawed methods for achieving comparable groups.

Ans: B

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Feedback: In pretest–posttest designs, data on the dependent variable are collected both before the intervention (a baseline measure) and after it (an outcome measure). In an experimental study, the independent variable typically is not “measured”; it is the variable manipulated by the researcher (e.g., receipt vs. nonreceipt of an intervention). Researchers do not often measure attitudes toward an intervention, and in any event, they would not be measured at the pretest stage of the project.

A) A crossover design allows participants to choose the intervention they will receive.

B) A crossover design is useful for eliminating crossover effects.

C) A crossover design is not a true experimental design.

D) A crossover design achieves the highest possible equivalence among participants exposed to different conditions.

Ans: D Feedback: In crossover designs, people are exposed to more than one condition and serve as their own controls—resulting in the highest possible equivalence among those being compared. Crossover designs, which are true experimental designs, do not allow participants to choose interventions they will receive. Crossover designs can be susceptible to carryover effects—that is, being influenced in the second condition by what participants experienced in the first.

What type of design was used?

A) Crossover B) Pretest–posttest design C) Delay of treatment D) Time series Ans: A Feedback: In this crossover design, all patients received both treatment conditions, in a randomized order. In a delay of treatment design, control group members are offered the intervention after being put on a wait-list, which did not occur in this example. Pretest–posttest designs involve multiple groups of participants randomized to different treatment conditions, which is not the case in this example.

B) The control group condition is a proxy for an ideal counterfactual.

C) Control groups never receive the experimental intervention.

D) The most common control group condition in nursing research is a “no treatment” control group.

Ans: B Feedback: In a true experiment or RCT, researchers use the control group as a proxy for an ideal (but physically impossible) counterfactual.

To test the effect of a Hatha yoga intervention on blood pressure, 100 prehypertensive adolescents were randomly assigned to either Hatha yoga classes or to an art class. This control group strategy is called: A) a “usual care” control group.

B) an attention control group.

C) a wait-listed control group.

D) an alternative treatment control group.

Ans: B Feedback: In this example, the art class was offered to students as a way of giving adolescents the same amount of special attention as those in the treatment group, without any of the hypothesized active ingredients of Hatha yoga. The art class was not “care as usual,” and there is no indication that the control group eventually received the yoga intervention. The art class is not especially likely to affect the adolescents’ blood pressure and so is not an alternative treatment.

Ans: D Feedback: The great strength of experimental studies lies in the confidence with which causeand-effect relationships can be inferred. Through the controls imposed by manipulation, control, and randomization, alternative explanations for group differences on the outcomes can usually be discredited. Limitations of experimental designs include that they may be more (not less) artificial than other designs, and they are often quite costly. Not all experimental studies are undertaken with a guiding theoretical framework.

A) RCTs are in the middle of most evidence hierarchies for Therapy questions.

B) RCTs are more susceptible to confounding variables than quasi-experiments.

C) Many variables of interest to nurse researchers cannot be experimentally manipulated.

D) RCTs are the most often used design for studying the effect of cigarette smoking on lung cancer.

Ans:C Feedback: A large number of human attributes cannot be randomly assigned to people (e.g., blood pressure, age, fatigue), and so experiments are not always feasible.

Nevertheless, RCTs are near the top of evidence hierarchies for Therapy questions, only one rung down from systematic reviews of RCTs. Quasi-experiments are lower down on evidence hierarchies for Therapy questions because they are more susceptible to confounding influences than RCTs. The link between lung cancer and smoking has never been studied in an RCT because it would be unethical to randomize people to a smoking or nonsmoking group.

Which of the following is invariably a feature of quasi-experimental research?

A) A control group B) An intervention C) Matching D) Randomization Ans: B Feedback: Quasi-experiments (trials without randomization) involve an intervention but lack randomization and, sometimes, lack a control group. Matching of subjects is a method of controlling confounding variables by consciously forming comparable groups; this strategy is used in some, but not all, quasi-experiments.

D) In a nonequivalent control group design, it cannot be assumed that any groups being compared are equivalent at the outset.

Ans: D Feedback:

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

One weakness of a nonequivalent control group design is that researchers cannot assume that groups being compared in terms of outcomes at the end of the study are comparable at the outset—there could potentially be many confounding variables. Quasi-experiments never involve randomization, and some do not involve a comparison group, but they do always involve an intervention.

A researcher initiated an innovative cigarette cessation intervention. Seventy participants received the intervention, and their cigarette smoking 3 months later was compared to smoking at baseline. What type of design is this?

A) A crossover design B) A nonequivalent control group pretest–posttest design C) A one-group pretest–posttest design D) A time-series design Ans: C Feedback: The researcher in this example used a very weak one-group pretest–posttest design. There was no repeated collection of data (so, not a time-series design), and no comparison group (thus, not a nonequivalent control group design). A crossover design is an experimental design that involves randomly assigning people to orderings of alternative treatments, which did not occur in this example.

A) A crossover design B) A nonequivalent control group pretest–posttest design C) A one-group pretest–posttest design D) A time-series design Ans: D Feedback: A time-series design involves the collection of outcome data over an extended period, during which time an intervention is introduced, as in this example. In a one-group pretest–posttest design, data are collected twice, whereas in this example, data were collected 24 times. There is no comparison group, so this is not an example of a nonequivalent control group design.

Compared to true experiments, quasi-experiments are more susceptible to: A) rival hypotheses about causality.

B) ethical transgressions.

C) feasibility problems.

D) recruitment difficulties.

Ans: A Feedback: A major disadvantage of quasi-experiments is that they are susceptible to rival hypotheses—that is, alternative plausible explanations for what caused the outcomes, rather than the intervention of interest. Quasi-experimental research is not more prone to ethical transgressions than true experiments, and in most cases, quasi-experiments are more feasible (not less feasible) than RCTs. Some people are reluctant to be randomized, and so it is often easier to recruit participants for a quasi-experimental study than for an RCT.

A) Researchers do not manipulate the independent variable.

B) Researchers do not manipulate the dependent variable.

C) Data are collected through the observation of participants’ behaviors.

D) Their ability to elucidate cause-and-effect relationships is unparalleled.

A weakness of correlational studies is that they can harbor biases due to selfselection into groups being compared, which in turn hinders causal inferences.

Correlational studies can be costly, but often they are not. They are less artificial than studies involving interventions and are often practical to implement.

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

The careful development of standard protocols is an important strategy for enhancing constancy of conditions in implementing an intervention. In carefully controlled quantitative research, steps are taken to achieve constancy in the study conditions so that researchers can be confident that outcomes reflect the influence of the independent variable and not the study context. All intervention research is prospective and not retrospective. The use of a homogeneous sample is used to control participant factors, not the study context, and maximizing statistical power enhances statistical conclusion validity, not constancy of conditions.

There are several alternative strategies for controlling confounding participant characteristics. Which method is the most effective?

A) Using a homogeneous sample B) Statistically controlling confounders C) Matching participants on confounding variables D) Randomizing participants to conditions Ans: D Feedback: Randomization is the most effective method of controlling participant characteristics because it controls all possible confounding variables.

A) Intervention effects B) Carryover effects C) Rival hypothesis effects D) Causal effects Ans: B Feedback: Crossover designs are often susceptible to the risk of carryover effects, which occur when the people who are exposed to two different conditions are influenced in the second condition by their experience in the first condition. Intervention effects are what researchers hope to find, they are not a problem. The terms “rival hypothesis effects” and “causal effects” are not research terms.

A) Randomly assigning participants to homogeneous groups B) Not allowing important confounders to vary in the research sample C) Making the treatment conditions as homogeneous as possible D) Creating homogeneous groups of participants through matching Ans: B Feedback: One way to control confounding participant characteristics is to not allow them to vary—that is, to select participants who are homogeneous with respect to confounders. Participants are not randomized to homogeneous groups, and homogeneity of treatment conditions is the opposite of what needs to occur to make the design powerful. The use of matching is unrelated to the strategy of minimizing variation in the sample with respect to confounders.

Matching is a common control procedure in case-control studies. In this example, the researcher would match patients with and without a herniated disc with respect to gender. Randomization is not used in case-control studies, and participants are used as their own controls only in crossover designs. Homogeneity could have been used to control gender by restricting the sample to either men or to women, but this was not done in this example.

A) Statistical control B) Matching C) Randomization D) Homogeneity Ans: A Feedback: Analysis of covariance is a method of statistical control that could be used to remove the effect of age on the residents’ quality of life—which would be desirable if those getting versus not getting the intervention were of different ages. In this quasi-experimental study, the groups were not formed through randomization.

Feedback: The history threat involves the occurrence of events concurrent with the independent variable that can affect the outcome.

A) Mortality B) Selection C) Maturation D) History Ans: A Feedback: Mortality is the threat that arises from differential attrition in groups being compared. RCTs avoid the selection threat through random assignment to groups, but people drop out of the study in a nonrandom manner, which can result in groups that are no longer equivalent. RCTs are not typically susceptible to history threats (co-occurring events) or maturation threats (the effects of the passage of time) because both treatment and control group subjects are equally exposed to both.

58. Using homogeneity as a strategy for controlling confounding variables can reduce which type of validity?

A) Statistical conclusion validity B) Internal validity C) External validity D) Construct validity Ans: C Feedback: External validity concerns inferences about whether relationships found for study participants might hold true for different people, conditions, and settings—in other words, generalizability. Using a homogeneous sample is easy, but one problem is that this strategy limits the generalizability of the results. Homogeneity usually helps to increase, not decrease, internal validity because confounders are controlled.

A) External validity is reduced in multisite studies.

B) The goals of internal validity and external validity can sometimes conflict.

C) External validity is higher in quasi-experimental than in experimental studies.

D) Internal validity is more important to EBP than external validity.

Ans: B Feedback: There is often tension between the demands required to achieve internal validity (where tight control enhance causal inferences) and external validity (where tight controls might introduce artificial circumstances that can limit generalizability).

External validity is often enhanced in multisite studies if results are replicated in diverse settings. For EBP, external validity—the ability to generalize evidence to new settings—is very important. External validity is not necessarily higher in quasiexperimental studies.

The accessible population is the aggregate of cases that conform to designated criteria and that are accessible—in this case, women with high-risk pregnancies in the state of New York. The target population is a broader group meeting the same eligibility criteria—the aggregate of cases about which the researcher would like to generalize the findings. In this case, the broader group would be women with highrisk pregnancies in the United States. Women who do not have high-risk pregnancies would not meet the criterion for being in the study. Women with highrisk pregnancies in a specific city (Albany) are not a broader group than those in the entire state.

Which would be a reasonable exclusion criterion?

A) People age 65 years or younger B) People who live in their own homes C) People who have periods of dizziness D) People who are married Ans: A Feedback: The study is focused on community-dwelling elders, and so it would be important to exclude people below a certain age limit (here, age 65 years). The researcher is thus defining “elder” as someone older than 65 years. One inclusion (rather than exclusion) criterion might be living independently in one’s own home. There would be no apparent reason to exclude married people or people who experience dizziness (which could contribute to fear of falling).

A) Identifying a set of criteria for selecting study participants B) Determining who is eligible to participate in a study C) Selecting a subset of the population to represent the entire population D) Ensuring that every element in the population has an equal chance of being included in the study Ans: C Feedback: Sampling is the process of selecting a portion of an entire population. Eligibility criteria are used to define population characteristics, and the application of those criteria is used to identify people who could participate in a study. Some sampling strategies (probability sampling) ensure that every element in the population has a chance to be sampled, but most strategies used by nurse researchers do not.

If a population was defined as military veterans in Texas, an element would be: A) An Army veteran hospitalized in Houston B) All residents of Texas C) Texans who are military veterans D) A soldier currently serving in the Army Ans: A Feedback: An element is the basic unit in the population—in this case, a person who previously served in the army and is hospitalized in a city in Texas, Houston. A soldier currently in the Army would not meet the criterion stipulated for the population— i.e., not a veteran. “All residents of Texas” is neither an element (a basic population unit) and is missing the eligibility criterion of being a military veteran. “Texans who are military veterans” is a restatement of the population and is not an element.

A) Lack of variability in the population on the attribute of interest B) Sample selection using probability sampling methods C) The margin of error in the data obtained from samples D) Systematic overrepresentation or underrepresentation of a key attribute vis-àvis the population Ans: D Feedback: Sampling bias is the systematic overrepresentation or underrepresentation of some segment of the population. Sampling bias is unrelated to how varied (heterogeneous) the population is and is not the margin of error in data from a sample. Probability sampling (in which elements are selected by random methods) is not as susceptible to sampling bias as nonprobability methods.

A) How representative the sample is of the population B) How easy it is to recruit sample members C) How convenient it is to the researchers D) How ethically sound the recruitment strategy is Ans: A Feedback: A key consideration in assessing the quality of a sample in a quantitative study is its representativeness of the population; another is the size of the sample. Ease of recruitment, convenience, and ethical appropriateness are important factors in a sampling strategy, but they do not contribute to the quality of the sample itself.

A nurse researcher is studying medication compliance in hypertensive patients.

Among those recruited to participate in the study, 50% of the women and 20% of the men agreed to participate. This situation is likely to lead to: A) revised eligibility criteria.

B) a power analysis.

C) a revised definition of the target population.

D) sampling bias.

Ans: D Feedback: Sampling bias is the systematic overrepresentation or underrepresentation of a population segment on a characteristic relevant to the research question. In this case, it appears that men will be systematically underrepresented, and a person’s gender might play a role in medication compliance. The situation described would not lead to revisions of the eligibility criteria or in how the target population is defined. A power analysis is used to identify sample size needs, not to address imbalances in the sample.

B) Strata are a means of equating the accessible population with the target population.

C) In a population of geriatric patients, those with and without a diagnosis of dementia would comprise two strata.

D) The use of strata in a sampling strategy can reduce the representativeness of the sample.

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Ans: C Feedback: Strata are subpopulations, such as older patients with and without dementia. The use of strata in sampling can improve (not reduce) the sample’s representativeness. The most basic unit of a population is not called a stratum—it is called an element. Strata have no role in equating accessible and target populations.

Which nonprobability sampling design would be most likely to yield a representative sample?

A) Consecutive sampling B) Convenience sampling C) Purposive sampling D) Quota sampling Ans: A Feedback: Consecutive samples are least likely to result in biased samples because all eligible people over a certain time period are invited to participate. Quota sampling is an improvement over convenience sampling in terms of yielding a representative sample, but sampling bias remains a problem. Purposive sampling is seldom representative of the population because subjective judgment is used to select participants—not every expert, for example, would have an equal chance of being selected from a population of experts on a topic.

A) Consecutive B) Purposive C) Quota D) Convenience Ans: C Feedback: Quota sampling divides the population into homogeneous strata (subpopulations) to ensure representation of different subgroups in the sample; within each stratum, people are sampled by convenience. Purposive sampling involves “handpicking” participants; there could be strata in purposive sampling, but this does not typically happen.

Which is the weakest form of sampling for quantitative studies?

A) Convenience sampling B) Quota sampling C) Purposive sampling D) Consecutive sampling Ans: A Feedback: Convenience sampling uses the most readily available or convenient group of people—people who may be atypical of the population; the price of convenience is the risk of bias. The other answers are also forms of nonprobability sampling; they are weaker than methods of probability sampling but are stronger than convenience sampling.

A) A stratum B) A sampling network C) A sampling frame D) A sampling quota

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Ans: C Feedback: Researchers can sometimes establish a sampling frame (a list of all elements in the population) for the purposes of random sampling. A stratum is a subdivision of a population, not a listing of elements. “Quota” is a term used for a type of sampling, not the name of a listing. The term “sampling network” is not a research term.

A) Lack of control over confounding variables B) Insufficient power to detect differences in groups being compared C) Lack of ability to stratify the sample D) Sampling bias Ans: B Feedback: When a sample is too small, the study may lack sufficient power to detect group differences in the sample at a statistically significant level, even if the differences exist in the population. Sample size does not affect control over confounding variables, nor does it limit stratification. Sampling bias is not necessarily a consequence of sample size but rather a consequence of the method used to select a sample (e.g., a nonprobability method).

What procedure do researchers use to estimate how large a sample they need?

A) Randomization B) Screening C) Power analysis D) Stratification Ans: C Feedback: In quantitative studies, researchers often use a power analysis to estimate sample size needs, which is a strategy for avoiding problems with statistical conclusion validity. Screening (e.g., for eligibility) and stratification (to enhance representativeness) are not relevant to sample size estimation. Randomization is not a sampling term—it refers to a strategy used to achieve comparable groups in experimental studies.

Questionnaires can be distributed and collected without knowing the identity (or characteristics) of individual respondents, but the same is not true of interviews.

Compared to questionnaires, interviews can be used with broader populations (e.g., people who cannot read or cannot see). However, interviews tend to be more costly than questionnaires because of the expense of hiring interviewers, and such expenses are magnified if the sample is geographically dispersed. Questionnaires can be distributed to people in wide geographic areas at low costs, especially over the Internet.

What is the name of a brief self-report method used to measure subjective experiences such as pain and fatigue?

A) Composite scales B) Dichotomous questions C) Visual analog scales D) Likert scales Ans: C Feedback: A visual analog scale (VAS) is used to measure subjective experiences (e.g., pain, fatigue) along a 100-mm line designating a bipolar continuum (e.g., no pain at all, pain as bad as it could be). Likert scales involve multiple items, scored together; these are sometimes called composite scales.

What is the name of the response bias that results when people consistently select the “strongly agree” or “strongly disagree” response alternatives?

A) Social desirability B) Extreme response C) Naysayers D) Acquiescence Ans: B Feedback: Extreme responses are a bias reflecting the consistent selection of extreme alternatives (e.g., “strongly agree”). These extreme responses do not necessarily signify the most intense feelings about a phenomenon but rather capture a personality trait of the respondent. Other types of response bias include social desirability, acquiescence, and naysayers bias, but these do not concern the systematic selection of the most extreme response options.

A) reactivity.

B) ethical problems.

C) lack of mobility.

D) acquiescence bias.

Ans: A Feedback: When data are obtained through direct observation, awareness of being observed may cause people to behave atypically, and this problem is called reactivity. When observers are not concealed, there is no ethical problem (as long as informed consent has been obtained). Mobility of observers or study participants is not an issue when observers are not concealed.

A researcher studying interactions among nursing home residents schedules 5minute observations, with six periods of observation per hour. What sampling strategy is the researcher using?

A) Event sampling B) Quota sampling C) Time sampling D) Consecutive sampling Ans: C Feedback: With time sampling, researchers select time periods during which observations will occur—in this case, there would be six observational sessions of 5 minutes (30 minutes of observation) each hour. Event sampling focuses on a specific type of event (e.g., episodes of severe agitation). Quota sampling and consecutive sampling are terms used primarily with regard to the sampling of participants, not observational periods.

Ans: D Feedback:

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Observation directly captures human behaviors and provides access to data that is often unattainable through self-reports. Participants seldom “enjoy” being observed and may in fact be nervous during observations. Because observation is laborintensive, it tends to be expensive. People are not anonymous when they are being observed.

B) Biomarkers are more likely to provide valid measures of the target variables than self-reports.

C) Biomarkers are less accurate and precise than composite scales.

D) Oxygen saturation is an example of an in vitro measurement.

Ans: B Feedback: Biophysiological instruments provide valid measures of targeted variables: Thermometers can be counted on to measure temperature and not oxygen saturation, for example. It is often more difficult to be certain that self-report instruments are really measuring the target concept. In vitro (not in vivo) measurements are performed outside a human body. Oxygen saturation is an example of an in vivo measurement. Composite scales are almost invariably less accurate and precise than biomarkers.

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

B) When researchers develop a new measure, they must learn what measurement rules apply to it.

C) Most measures of attributes of interest to nurse researchers are free from measurement error.

D) Evaluation of a new measure involves an assessment of 10 distinct measurement properties.

Ans: A Feedback: Measurement involves assigning numbers to represent the amount of an attribute present in an object/person using a specified set of rules—and for many attributes of interest (e.g., resilience, self-efficacy), the rules must be invented. When researchers develop a new measure, they must create the rules, not learn what they are. Virtually all measures are susceptible to measurement error. New measures are typically evaluated using 2 (not 10) measurement properties; 2 additional measurement properties relating to change scores may sometimes be assessed.

A nurse researcher developed a new 10-item scale to measure resilience. The researchers evaluated whether all 10 items were measuring the same trait. Which of the following was being assessed?

A) Interrater reliability B) Internal consistency C) Test–retest reliability D) Content reliability Ans: B Feedback: Internal consistency concerns the extent to which all the items on a composite scale are consistently measuring the same attribute. Test–retest reliability assessments concern the stability of a measure over time and involve two administrations of the measure to the same people. Interrater reliability involves comparing the scores of two people assigning scores (e.g., scores from an observational rating scale). There is no such thing as content reliability.

A) Content validity B) Face validity C) Criterion validity D) Construct validity Ans: A Feedback: Content validity is the extent to which a multi-item scale’s content (the items) adequately captures the focal construct. Content validity, unlike criterion or construct validity, is usually assessed with feedback from a panel of experts. Face validity refers to whether the scale looks like it is measuring the target construct and is often assessed by getting feedback from the population for whom the scale is intended.

Quantitative researchers specify a research design before collecting their data and rarely depart from that design once the study is underway: They design and then they do. In qualitative research, by contrast, the study design typically evolves during the project: Qualitative researchers design as they do. Qualitative researchers do not attempt to control any aspect of the study context, and internal validity is not a concern to qualitative researchers.

Ethnography is a discipline that focuses on the culture of a group of people and relies on extensive, in-depth fieldwork. Ethnographers strive to acquire an emic (insider’s) perspective of a culture rather than an etic (outsider’s) perspective, and they do not seek to link the etic and the emic perspectives. Phenomenologists seek to discover the essence and meaning of a phenomenon as it is experienced by people.

B) An etic perspective of a culture C) A focused perspective D) An ethnonursing perspective Ans: A Feedback: Ethnographers strive to acquire an emic perspective of a culture—an insider’s view that is the way members of the culture envision their world. An etic perspective is the outsiders’ interpretation of the experiences of that culture. Focused ethnography focuses on narrowly defined cultures, but it is not a “perspective,” nor is ethnonursing a perspective, but rather an approach to studying people’s viewpoints, beliefs, and practices related to health.

D) A case study design can be cross-sectional or longitudinal.

Ans: D Feedback: Case studies can involve the collection of data from a single point in time but can also be longitudinal to understand how circumstances and conditions evolve. Case studies are not merely anecdotal descriptions. A limitation of case studies is that the findings may not be generalizable. The entity for a case study could be a person, family, institution, or another social unit.

A researcher collected stories about how 16 suicide survivors felt when they learned their suicide attempts had failed. What type of qualitative study is this likely to be?

A) Historical research B) Qualitative description C) A case study D) A narrative analysis Ans: D Feedback: Narrative analysis focuses on story in studies in which the purpose is to determine how individuals make sense of events in their lives—here, the stories of those with an unsuccessful suicide attempt. Historical research is the systematic collection and critical evaluation of data relating to past occurrences. Descriptive qualitative studies are not embedded in a disciplinary tradition but use qualitative approaches to describe a phenomenon. Case studies are intensive investigations of a single entity or a small number of entities (e.g., individuals, families).

Objective: 05 Page and Header: 168, Descriptive Qualitative Studies 32. The terms “content analysis” and “thematic analysis” are usually associated with which of the following?

A) Descriptive phenomenology B) Descriptive qualitative research C) Ethnography D) Hermeneutics Ans: B Feedback: Many qualitative studies are not embedded in a research tradition. When researchers undertake a descriptive qualitative study, they often say that they have undertaken a content analysis or a thematic analysis. These terms are not associated with descriptive phenomenology, ethnography, or hermeneutics—all of which are qualitative research traditions.

Critical research differs from traditional qualitative research in its: A) goal to be transformative.

B) use of interviews as a data source.

C) use of reflexivity.

D) desire to gain an in-depth understanding of phenomena.

Ans: A Feedback: Critical theory is concerned with a critique of existing social structures. Critical researchers conduct studies that involve collaboration with participants and that foster enlightened self-knowledge and transformation. This differs from traditional qualitative research, although critical research also uses qualitative methods. All of the other answers are true of qualitative research in general.

What is the central concern of a critical researcher?

A) A critique of the research methods of a completed study B) A critique of society and social practices C) A critique of existing theories D) A critique of self Ans: B Feedback: A critical researcher is concerned with a critique of society and with envisioning new possibilities. The broad aim of critical social science is to integrate theory and practice such that people become aware of contradictions and disparities in their beliefs and social practices and become inspired to change them. Critical research does not involve a critique of the self, existing theories, or research methods.

Page 20

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Constructivist grounded theory is not an approach that is linked to ideological perspectives; all of the other answers are types of research with an ideological perspective. Critical ethnography focuses on raising consciousness in the hope of effecting social change. Feminist research aims at being transformative, with a focus on how gender domination and discrimination shape women’s lives.

Participatory action research (PAR) produces knowledge through close collaboration with groups that are vulnerable to control or oppression by a dominant culture.

Which statement about ideologically based research is true?

A) Critical researchers and feminist researchers interact with participants in collaborative ways that emphasize participants’ expertise.

B) Critical theory has played an especially important role in phenomenology (critical phenomenology).

C) Critical research has often been criticized for being exploitative.

D) Participatory action research is typically undertaken in the organization with which the researcher is affiliated.

Ans: A Feedback: Critical and feminist researchers, as well as participatory action researchers, seek to establish collaborative and nonexploitative relationships with their informants and to conduct research that is transformative. Critical theory has played an especially important role among ethnographers, not phenomenologists.

Participatory action research is conducted with disadvantaged groups or communities that are oppressed by a dominant group, which is not typically the case in organizations with which researchers are affiliated.

A) Critical ethnography B) Participatory action research C) Feminist research D) Critical grounded theory Ans: B Feedback: In participatory action research (PAR), the researchers and study participants— often residents in vulnerable communities—collaborate on a wide range of research activities, including the definition of the problem and various methodological and interpretive decisions. Critical ethnography and feminist research are two other types of research with an ideological perspective, but full collaboration between researchers and participants is not typical.

A) How many people do I need to achieve adequate power?

B) Who would be a rich information source for my study?

C) Will my sample be representative of the target population?

D) To which group will I be able to generalize my findings?

Ans: B Feedback: Qualitative researchers seek a relatively small number of study participants who will be rich sources of information about the phenomenon of interest. Large, representative samples that provide adequate power and permit generalizability are desirable in quantitative studies.

A) Both involve the development of eligibility criteria before recruiting study participants.

B) Both involve the use of random samples whenever possible.

C) Both rely on power analysis to estimate sample size needs.

D) Generalizability is a major quality criterion in both types of research.

Ans: A Feedback: Both quantitative and qualitative researchers specify the criteria for a population of interest—that is, the characteristics of people would be eligible to participate in the study. Only in quantitative research do researchers use power analysis and select participants randomly if possible. Generalizability is not a quality criterion in qualitative research—although qualitative researchers do attend to the transferability of findings to other settings.

Feedback: Snowball sampling involves asking early participants to refer other study participants who meet the eligibility criteria and have experienced the phenomenon of interest. Convenience sampling (also called volunteer sampling) involves selecting the most readily available persons to participate. Purposive sampling is selecting cases based on the researcher’s judgment about who will be most informative.

A) Convenience sampling is only useful at the end of the sampling process.

B) Convenience sampling is too expensive.

C) Convenience sampling is inefficient.

D) Convenience sampling may not yield the most information-rich sources.

Ans: D Feedback: Sampling by convenience is efficient and relatively inexpensive but is not a preferred approach, even in qualitative studies because it is not the best way to recruit participants who can maximize the quality of the data. Convenience sampling, if used at all, is best used as a starting point for sampling at the beginning of a study, not at the end of sampling.

B) Quantitative researchers establish eligibility criteria, but qualitative researchers do not.

C) Another name for snowball sampling is volunteer sampling.

D) Qualitative researchers do not need to be as concerned as quantitative researchers about the quality of their samples.

Ans: A Feedback: Convenience sampling is used by both quantitative and qualitative researchers, but it is not the preferred approach by either group. Both quantitative and qualitative researchers identify eligibility criteria for their studies, and both are concerned about the quality of their samples (although they use different criteria for deciding what a “good” sample is). Another name for snowball sampling is network sampling, not volunteer sampling.

What is the name of that broad strategy?

A) Convenience sampling B) Consecutive sampling C) Snowball sampling D) Purposive sampling Ans: D Feedback: Purposive sampling is a broad category of sampling that is a purposeful approach— that is, it is focused on the selection of cases that will best meet the substantive demands of the study. Convenience sampling and snowball sampling are methods that do not rely on the researcher’s judgments about whom to sample next.

Consecutive sampling is used in quantitative studies, not qualitative ones.

A nurse researcher studied barriers to smoking cessation among pregnant women. The study involved in-depth interviews with 22 women who were selected to be different in terms of their parity, education, and length of time as a smoker.

Which sampling method was used?

A) Maximum variation sampling B) Typical case sampling C) Extreme case sampling D) Criterion sampling Ans: A Feedback: There are several types of purposive sampling, one of which (maximum variation sampling) involves purposefully selecting participants with variation on several key dimensions. In this example, the researcher deliberately included participants with a wide range of traits, who presumably would face diverse barriers to smoking cessation during their pregnancy. The other answers are for other forms of purposive sampling, but these methods were not used in this example.

There are several types of purposive sampling, one of which (extreme case sampling) involves an effort to learn from the most unusual or extreme cases. In this example, the researcher selected cases that had experienced severe bullying and studied them in depth. The other answers are for other forms of purposive sampling, but these methods were not used in this example.

A nurse researcher studied how men coped with a diagnosis of prostate cancer.

The researcher concluded that early adjustment to the diagnosis involved a process provisionally described as “reframing.” The researcher then deliberately tried to sample people for whom reframing was not apparent. Which sampling method was used toward the end of this study?

A) Criterion sampling B) Sampling disconfirming cases C) Extreme case sampling D) Maximum variation sampling Ans: B Feedback: Sampling disconfirming cases, which tends to be used toward the end of data collection, is a purposive approach that involves searching for cases that challenge researchers’ interpretations. The negative cases may be exceptions that refute earlier conceptualizations and suggest rival explanations about the phenomenon.

The other answers are for other forms of purposive sampling, but these sampling strategies do not involve a search for “disconfirming” cases.

B) Larger samples are considered more useful than smaller samples.

C) Using randomness in the sampling process is desirable, especially at the beginning of the study.

D) The type of sampling approach can change and evolve over the course of data collection.

Ans: D Feedback: In qualitative studies, the sampling strategy can change over the course of a study.

Qualitative sampling may begin with a convenience sample, but many studies evolve to a purposive strategy in which researchers choose the types of cases that will best contribute to the conceptualization. Sampling by convenience is not a preferred approach, even in qualitative studies. Qualitative researchers avoid random samples because they are not the best method of selecting people who will make good informants. Small samples are preferred because sample members can be studied intensively.

A) Ethnography B) Descriptive phenomenology C) Interpretive phenomenology D) Grounded theory Ans: D Feedback: Theoretical sampling is a sampling approach used primarily by grounded theory researchers, not by ethnographers or phenomenologists. The goal in a grounded theory study is to select informants who can best contribute to the evolving theory.

Format: Multiple Choice Chapter: 11 Client Needs: Physiological Integrity: Physiological Adaptation Cognitive Level: Understand Difficulty: Moderate Integrated Process: Nursing Process Objective: 02 Page and Header: 177, Theoretical Sampling 14.

Theoretical sampling involves making decisions about where to find the best data to develop and refine an emerging theory or conceptualization. Sampling that involves studying cases that meet a predetermined criterion of importance is called criterion sampling. Extreme (deviant) case sampling provides opportunities for learning from the most unusual or extreme informants. The purposive strategy designed to ensure diversity on important characteristics is called maximum variation sampling.

A) Sampling to the point at which new information continues to be obtained B) Sampling to the point at which the target population is saturated with requests for data C) Sampling to the point at which redundancy of information is achieved D) Sampling to the point at which maximum variation is achieved Ans: C Feedback: Data saturation occurs at the point at which no new information is obtained by adding new study participants and when redundancy is achieved (not when new information is still being gathered). Data saturation does not concern maximum variation or saturating the population with data requests.

B) If the quality of data being collected is exceptionally strong, a smaller sample may suffice than when data quality is mediocre.

C) Typical case sampling requires more participants than maximum variation sampling.

D) Sampling for qualitative studies should stop before information becomes redundant.

Ans: B Feedback: With rich, high-quality data, fewer cases may be needed to achieve a good understanding of the phenomenon of interest. New researchers usually need a larger (not a smaller) sample than experienced researchers, who are likely to be more adept at eliciting high-quality data. Maximum variation samples are typically larger than typical case samples. Qualitative researchers need to achieve redundancy of information to recognize when sampling can stop.

A) Ethnographers sample not only people but also events, records, artifacts, and other features of a culture.

B) Ethnographers usually have at least 100 key informants in their samples.

C) Ethnographers avoid conversing with many people, restricting their sample to a few expert cultural consultants.

D) Ethnographers select key informants using convenience sampling.

Ans: A Feedback: To fully understand a culture, ethnographers sample not only people but also other things to observe, such as activities and products of the culture. Ethnographers typically work with a relatively small sample of key informants, but they often begin by having conversations with dozens of members of the culture. Key informants are then selected purposively, using a framework that helps the researchers understand the types of people needed to understand the culture.

B) Phenomenological researchers sample not only people but also events, activities, diaries, and records relating to the target phenomenon.

C) The sample size in phenomenological studies is typically 15 or fewer participants.

D) An eligibility criterion for a phenomenological study is that participants must belong to a particular culture or social group.

Ans: C Feedback: In a phenomenological study, the sample is typically very small (15 or fewer). A key eligibility criterion is that the participants must be people who have experienced the phenomenon of interest. Unlike ethnographers, phenomenologists primarily sample people, with whom they have in-depth discussions rather than activities, events, or artifacts. Participants do not have to be members of a particular culture or social group in a phenomenological study.

Which is a key criterion for being included in a sample for a phenomenological study?

A) The person must belong to a particular culture or social group.

B) The person must have considerable factual knowledge about the phenomenon being studied.

C) The person must be willing to be exposed to the phenomenon under study.

D) The person must have experienced the phenomenon being studied.

Ans: D Feedback: Two principles guide the selection of a sample for a phenomenological study: (1) All participants must have experienced the phenomenon and (2) they must be able to articulate what it is like to have lived that experience. Having considerable factual knowledge about the phenomenon is not a key criterion, nor is being a member of a particular social or cultural group. Willingness to experience the phenomenon is not relevant—the experience must already have happened.

Which statement about sampling in grounded theory studies is true?

A) Grounded theory researchers start with theoretical sampling and then later evolve to a snowballing approach.

B) In a grounded theory study, sampling, data collection, data analysis, and theory construction occur concurrently and iteratively.

C) Grounded theory researchers do not use the principle of data saturation in their sampling approach.

D) Grounded theory studies typically involve samples of 50 to 60 people.

Ans: B Feedback: In a grounded theory study, researchers typically move through several sampling strategies—while collecting and analyzing their data—to find people who best contribute to an evolving theory. They may start with convenience sampling, but they eventually use theoretical sampling as the theory emerges. Grounded theory studies typically involve 20 to 30 participants. Saturation is the principle used in grounded theory studies (and other qualitative studies) to guide decisions about when to stop sampling new participants.

Feedback: Thick description is a term that refers to richly thorough depictions of research settings and the sample of study participants (or events); thick description is needed in qualitative reports to support transferability of findings to other settings or groups. Data saturation, key informants, and disconfirming cases are not strategies that support transferability.

B) The use of random or consecutive sampling is especially desirable.

C) Sampling plans are specified before the study gets underway.

D) Sample selection is driven by conceptual requirements, not by a desire for representativeness.

Ans: D Feedback: Qualitative researchers strive to meet conceptual requirements in selecting informants; representativeness is not a goal, and so qualitative samples are rarely randomly or consecutively selected. Qualitative sampling is emergent, not specified in advance of the study. Some qualitative studies have 15 or fewer participants, but many have 20 or more.

A) Qualitative researchers are as likely as quantitative researchers to gather biophysiological data.

B) Qualitative researchers typically incorporate scales into their data collection protocols.

C) The main source of data for qualitative studies is in-depth interviews.

D) The research tradition that uses the greatest diversity of data sources is phenomenology.

Ans: C Feedback: In all qualitative traditions, in-depth interviews are used to gather data and are a leading data source. Qualitative researchers rarely collect biophysiological data or use psychosocial scales. Ethnographers rather than phenomenological researchers rely on a great diversity of data sources—they use interviews and participant observation and also gather information from records, photographs, and other cultural artifacts.

The researcher began the interview by asking “Can you tell me what it was like when you first learned that your child had leukemia?” This is an example of which type of question?

A) A focused question B) A grand tour question C) A brainstorming question D) A topical question Ans: B Feedback: The question in this example is a broad, unstructured question designed to launch an in-depth discussion of the parents’ feelings and experiences relating to their child’s diagnosis. Such a question is called a “grand tour” question and would be followed by more focused questions. It is not a “brainstorming question” or a “topical question”—these are not research terms.

A) At what point did you evacuate the area?

B) What kind of damage did your home sustain?

C) What was it like to live through an earthquake?

D) Where were you at the time the earthquake occurred?

Ans: C Feedback: A grand tour question is a broad question asked early in an unstructured interview to gain a general overview of a phenomenon, from which more focused questions are asked—here, a question about what it was like to experience an earthquake.

The other questions are much more focused and in some cases would be more appropriate in a structured interview for a quantitative study (e.g., the question about where the person was when the earthquake occurred, for which response options could be created).

Focus group interviews are discussions among group members and do not involve asking everyone in the room the same question. Focus groups are more efficient than individual interviews because data from many people are gathered simultaneously. Most focus group sessions involve groups of 5 to 10 people.

An ethnographer is studying the culture of a refugee community in Toronto. The interviews take place in the participants’ homes, and the interviewer asks participants to talk about family pictures and souvenirs that are on display. What type of interview is this?

A) A focus group interview B) Photovoice interview C) A photo elicitation interview D) A structured interview Ans: C Feedback: Photo elicitation involves an interview stimulated and guided by existing photographic images, as is the case in this example. It is not an example of photovoice, which involves the researcher asking participants to take photographs of their world and interpreting those pictures for the researcher. This is not a focus group interview or structured interview.

Which statement about collecting self-report data in qualitative research is true?

A) Most qualitative researchers audiorecord their interviews for later transcription.

B) The most common method of conducting in-depth qualitative interviews is over the telephone.

C) Interviews for qualitative studies are conversational, so researchers avoid doing any preparation that could reduce spontaneity.

D) When interviewing participants, qualitative researchers ask their questions in a predetermined order to avoid bias.

Ans: A Feedback: The best way to have a good record of what participants say in an in-depth interview is to record the interview and then have the recording transcribed.

Qualitative researchers do not have a set of questions that must be asked in a specific order. Although qualitative interviews are conversational, interviewers benefit from advance planning, such as learning how best to word questions to match participants’ world view and language. Qualitative interviews are seldom conducted over the telephone because it is more difficult to establish rapport and trust over the telephone than in person.

Which statement about unstructured observation is true?

A) Unstructured observation is synonymous with participant observation.

B) Participant observation involves prolonged periods of social interaction between researchers and participants.

C) Researchers seek to gain “front stage” knowledge of the group or culture under study.

D) Participant observation is a technique unique to ethnographers.

Page 19

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Ans: B Feedback: Participant observation can only be successful when researchers spend prolonged periods of time in the field and gain the trust of members of the group being studied. Not all observation for qualitative studies involves participation, and so unstructured observation is not synonymous with participant observation.

Observers seek not to be restricted to “front stage” knowledge, which typically involves a protective façade against outsiders. Qualitative traditions other than ethnography (e.g., grounded theory) sometimes use participant observation as a method of data collection.

Which statement about participant observation is true?

A) Participant observers usually maintain the same level of participation throughout the study.

B) In a participant observation study, participants are observed but not questioned.

C) Participant observers typically use a combination of strategies for positioning themselves during observations.

D) Participant observers most commonly record their observations by videotaping the events and transactions they observe.

Ans: C Feedback: Participant observers often use a combination of positioning approaches, such as staying in a single location (single positioning), moving around the site (multiple positioning ), or following a person (mobile positioning). The level of participation usually evolves over the course of a study, with growing levels of participation as trust is gained. Participant observers seldom video record their observations, as this would undermine their status as a participating member. Participant observation almost always involves gathering self-report as well as observational data.

On 10 consecutive days, the researcher shadows a different staff member and observes his or her behavior and actions. This is an example of which type of positioning?

A) Single positioning B) Multiple positioning C) Mobile positioning D) Selective positioning Ans: C Feedback: Mobile positioning involves following a person throughout a given activity or period—in this example, a different member of the ICU staff each day. Single positioning involves staying in a single spot to observe behaviors in that location.

Multiple positioning involves moving around the site to observe behaviors from different locations. The term selective positioning is not used in connection with participant observation.

Researchers address various questions of substantive interest in their observations of a group or community under study, such as how communication is patterned, what the group’s activities are, and what roles people play in the group. Being able to charge one’s electronic devices may well affect the study, but it is not a substantive concern.

A) Reflective notes about the observer’s personal experiences and reflections B) An interpretation of what the observer witnessed C) Notes on what the observer would like to pursue the next day D) A record of what the observer did in the field each day Ans: D Feedback: A log (or field diary) is a daily record of events and conversations in the field. It is a chronological listing of how researchers spent their time. The other answers are recorded in field notes. Field notes are broader and more interpretive than logs— they represent the observer’s efforts to record information and to synthesize and understand the data as well as to make note of suggested strategies for future data collection.

Mixed methods research offers several advantages. Which is one of those advantages?

A) The potential for enhanced validity B) The cost-effectiveness of using two methods simultaneously C) The opportunity for multiple publications D) The ability to complete the study fairly quickly Ans: A Feedback: When a hypothesis is supported by complementary types of data in a mixed methods (MM) study, researchers can be more confident about the validity of their conclusions. MM studies are typically time-consuming and expensive. MM research might lead to many publications, but this is not a specific advantage; single-strand studies can also lead to numerous publications.

D) methodological research.

Ans: C Feedback:

Page 1

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Triangulation involves the use of multiple approaches to converge on the truth, and that is what occurs in mixed methods research. When a hypothesis or model is supported by multiple and complementary types of data, researchers can be more confident about their inferences. Hypothesis testing and theory generation do not require the integration of quantitative and qualitative approaches. Methodological research entails investigations of the methods for conducting rigorous research; most methodological research is quantitative.

Which of the following statements is true of mixed methods research?

A) Quantitative and qualitative methods are complementary and can help researchers avoid the limitations of a single approach.

B) A mix of qualitative and quantitative research should be used in all research studies.

C) Using mixed methods is not as popular as a research strategy as it was a decade ago.

D) An advantage of mixed methods research is that people are more likely to participate because the experience is enjoyable.

Ans: A Feedback: Quantitative and qualitative approaches are complementary. By using mixed methods, researchers might avoid the limitations of a single approach. Mixed methods research can be useful but is not needed or appropriate for all studies.

Mixed methods research is growing, not waning, in popularity. It is no easier to recruit participants for a mixed methods study than for other studies—and it may be more difficult if the time demands are greater.

4. What paradigm has most often been associated with mixed methods research?

A) Positivism B) Constructivism C) Pragmatism D) Postpositivism Ans: C Feedback: The paradigm called pragmatism is most often associated with mixed methods research. Pragmatist researchers consider that the questions in which researchers are interested should drive the inquiry and that the questions are more important than the methods needed to answer them. Positivism and postpositivism are the paradigms associated with quantitative research, and constructivism is the paradigm associated with qualitative research.

Which of the following is an important application of mixed methods research?

A) Measuring costs and benefits of an intervention B) Instrument development C) Planning a pilot study D) Assessing the reliability of a new instrument Ans: B Feedback: New instruments are often developed by combining qualitative and quantitative data collection approaches. Mixed methods research is often used in developing an intervention but not for undertaking a cost/benefit analysis, which relies on quantitative methods. Mixed methods may be used in a pilot study but not in planning for one. Assessing the reliability of an instrument relies on quantitative methods.

A) An intervention needs to be developed with input from stakeholders, and then a rigorous, formal evaluation will be needed.

B) The complexity of the problem makes a single approach inadequate.

C) The creation of a formal instrument is desired, but first, the concepts need to be better understood.

D) The qualitative results are puzzling, and quantitative results will help to explain them.

Which of the following is a key design decision in mixed methods studies?

A) Whether to collect both quantitative and qualitative data B) How the quantitative and qualitative strands should be sequenced C) How to combine sequential and concurrent strands D) Whether to tell participants that the study is mixed methods Ans: B Feedback: The sequencing of strands is a major design decision—i.e., whether to collect quantitative and qualitative data simultaneously or in a specified sequence. By definition, a mixed methods study involves collecting both quantitative and qualitative data. There is no such thing as a sequential or a concurrent “strand.”

Telling people about the study design is not a design decision—and most laypeople would not understand the “mixed methods” terminology.

B) The two strands occur prior to informing the third and fourth strands.

C) The first strand occurs prior to the second strand.

D) The sequencing of strands is selected at random.

Ans: C Feedback: In terms of sequencing, mixed method designs are either concurrent (wherein the quantitative and qualitative strands are undertaken in one simultaneous phase) or sequential (wherein one strand occurs prior to the second strand and informs that second strand). There are only two strands—qualitative and quantitative—not three or four, although there may be three or more phases in a sequential design.

Using the Creswell and Plano Clark design terminology, which specific design did the researcher use?

A) Explanatory design B) Convergent design C) Exploratory design D) Embedded design Ans: B Feedback: In a convergent design, researchers obtain different, but complementary, data about the central phenomenon under study. In this design, qualitative and quantitative data are collected simultaneously and with equal priority. Explanatory and exploratory designs are not concurrent. “Embedded” is a term used to designate a design in which the second strand is subservient to the dominant strand, but it is no longer considered a type of design in the Creswell and Plano Clark typology.

The construct validity of a new intervention is enhanced through efforts to develop an intervention theory that articulates what must be done to achieve desired outcomes. Intervention can sometimes yield data for secondary analysis, but this is not necessarily the case. Some intervention research could involve a methodological component (e.g., developing a new scale), but this is not typical.

Outcomes research (a subset of health services research) is undertaken to document the quality and effectiveness of health care and nursing services. Process analyses describe the process by which a particular program gets implemented and how it functions in practice. Economic analyses involve assessments of whether the benefits of a particular program or intervention outweigh the monetary costs. In methodological research, investigators focus on the development and assessment of methodological strategies.

B) The American Academy of Nursing rejected Donabedian’s framework and created the Nursing Outcomes Model as an alternative.

C) Nursing-sensitive outcomes are patient outcomes that are affected by the quality and quantity of nursing care.

D) In the Donabedian’s framework, nursing process variables include nursing skill mix and nursing experience.

Ans: C Feedback: Nursing-sensitive outcomes are patient outcomes that improve if there is a greater quantity or quality of nurses’ care (e.g., patient falls, pressure ulcer incidence). The attribution of patient outcomes to nursing outcomes is difficult because of the complexity of actions by the health care team. The American Academy of Nursing modified (but did not reject) Donabedian’s framework and developed the Quality Health Outcomes Model. Nursing skill mix and nursing experience are structural variables, not process variables.

A) They tend to be more expensive than other methods of doing surveys.

B) They involve a lot of personnel time.

C) They are not appropriate for longitudinal studies.

D) They tend to have low response rates.

Ans: D Feedback: Internet surveys are economical and do not require a lot of personnel time, but a major drawback is that response rates tend to be low, which in turn means that there is likely to be sampling bias. Internet surveys can be used for both crosssectional and longitudinal studies.

D) methodological study.

Ans: C Feedback: A Delphi survey involves asking a panel of experts to complete several rounds of questionnaires focusing on their judgments, in this case about nurses’ roles vis-àvis patients with Parkinson’s disease. In a Delphi survey, multiple iterations of questioning are used to achieve consensus. This is not an example of a secondary analysis (data were newly gathered for the study), or a process analysis, which involves a study of how a program gets implemented.

In a study on patients’ fear of falling, a nurse researcher administered a questionnaire; one question asked about the participants’ educational attainment (1 = high school, 2 = some college, 3 = college degree, 4 = graduate degree). In this example, what is the level of measurement of the variable educational attainment?

A) Nominal B) Ordinal C) Interval D) Ratio Ans: B Feedback: The researcher operationalized educational attainment as an ordinal-level variable.

Respondents were asked to choose one of several categories that were rank ordered according to the amount of education attained. The numbers associated with the categories do not indicate how much greater one category is than the other (i.e., this is not interval and ratio measurement). Unlike nominal measurement, however, the numbers (1, 2, 3, and 4) do convey quantitative information.

Which measure exemplifies ratio-level measurement?

A) Scores on a depression scale B) Apgar scores C) Urine output in milliliters per hour D) Employment status Ans: C Feedback: Urine output in milliliters per hour is measured on a ratio-level scale; it has a rational zero, and values would be equidistant. Scores on a depression scale would likely be considered interval-level, Apgar scores are ordinal, and employment status could be nominal (e.g., working/not working) or ordinal (e.g., not working, working part-time, working full-time).

Page 2

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

A) Nominal B) Ordinal C) Interval D) Ratio Ans: C Feedback: Scores on a psychosocial scale are considered to be interval-level measures. The scores are ordered to indicate increasing amounts of caregiver burden in equal intervals (and so, not ordinal measurement), but there is no rational zero point (and so, not ratio measurement). Unlike nominal measurement, the numbers in this example (scores) would convey quantitative information.

A) The average B) The mode C) The median D) The mean Ans: C Feedback: When a distribution is skewed, as it would be for the residents’ age at onset in this sample, the preferred index is the median—the value that divides the cases is half.

The mean, which is the same as the average, is the sum of all values divided by the number of people; the mean would distort what is a “typical” age at onset because there would be a negative skew, with some having an early age at onset but most having a later age.

A) The older the patient, the much greater the pain score.

B) Older patients had pain scores 2% higher than younger patients.

C) Older patients had pain scores similar to younger patients.

D) The relationship between pain scores and age was perfect.

Ans: C Feedback: A correlation coefficient communicates both magnitude and direction of a relationship. A correlation of .02 is very small—signifying virtually no relationship at all. Thus, in this analysis, younger and older patients had similar scores. A correlation of 1.00 (or –1.00) signifies a perfect relationship.

The absolute risk reduction index is an estimate of the proportion of people in the control group who could have been spared an undesirable outcome (here, continued smoking) had they been exposed to the intervention. Absolute risk is the proportion of people who experience an undesirable outcome in each group. The odds ratio measures the proportion of subjects who experienced an undesirable outcome relative to those who experienced a desirable outcome.

Which of the following is the standard deviation of a sampling distribution of means?

A) Sampling error B) Standard error of the mean C) Mean difference D) Square of the standard deviation Ans: B Feedback: The standard error of the mean (SEM)—the standard deviation of a theoretical sampling distribution of means—indicates the degree of average error of a sample mean. Sampling error occurs when sample values differ from population values. A mean difference is the difference between two group means and is unrelated to sampling distributions. The square of an SD is another index of variability (known as the variance) and is also unrelated to sampling distributions.

B) measurement error.

C) a sampling bias.

D) a sampling error.

Ans: D Feedback: Statistics are rarely exactly the same values as population parameters; the fluctuations in sample values result in sampling error. Sample bias concerns how well the sample reflects population characteristics, and measurement error concerns the reliability of measures used to collect data. A Type I error is one of two broad classes of errors in statistical decision making.

The standard error of the mean (SEM) gets smaller as which occurs?

A) The mean gets smaller B) The sample size gets smaller C) The mean gets larger D) The sample size gets larger Ans: D Feedback: Larger samples increase the precision of estimates of the population mean, and so larger samples are associated with smaller standard errors of the mean (SEMs).

The value of the SEM is unrelated to the value of the means.

Chapter: 13 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Analyze Difficulty: Moderate Integrated Process: Teaching/Learning Objective: 03 Page and Header: 219, Sampling Distributions 34. Which statement about standard errors of the mean (SEM) and sampling distributions is true?

A) One component in the formula for estimating SEMs is the standard deviation for the sample.

B) Researchers construct sampling distributions from their study data.

C) A sampling distribution of the mean is positively skewed.

D) The larger the SEM, the more accurate are sample means as estimation of population means.

Ans: A Feedback: The formula for estimating SEMs involves two pieces of information—the SD for the sample and sample size. Sampling distributions are theoretical and are not based on actual data. The accuracy of parameter estimates is enhanced when SEMs are smaller, not larger. Sampling distributions are unimodal and normal; they are not skewed.

Confidence intervals provide an estimate of how precise estimates of effects are— they indicate the range of values within which the “true” effect probably lies, with a given probability. The smaller the interval, the more precise the estimates. CIs do not answer questions about the quality of evidence, the magnitude of effects, or costs of applying evidence.

A) .05% B) 520 C) 18.0 to 22.0 D) .95 Ans: C Feedback: A point estimate is a single statistic that is used to estimate a population parameter—it is not a range of values. The values of 520 and .95 could be point estimates of population means, and .05% could be a point estimate of a population percentage.

Ans: B Feedback: In a normal distribution, 95% of the scores lie within about 2 SDs (more precisely, 1.96 SDs) from the mean. To calculate a 95% CI, the value of 1.96 is multiplied to the standard error of the mean, and that value is added to and subtracted from the sample mean to arrive at a range of scores within which the population value has a 95% probability of lying. For a 99% CI, the value is 2.58 SDs. The CI calculation does not depend on the sample size.

Consider the following hypothesis: The amount of daily daylight is unrelated to levels of depression in older adults. What type of hypothesis is this?

A) Research hypothesis B) Alternative hypothesis C) Parametric hypothesis D) Null hypothesis Ans: D Feedback: A null hypothesis predicts the absence of a relationship between variables, as in this example (“unrelated”). The research (or alternative) hypothesis for this example might be as follows: The greater the amount of daily daylight, the lower the levels of depression among older adults.

A) A Type I error occurs when a researcher concludes that there is no relationship between variables when there is one.

B) A Type II error occurs when a researcher concludes that there is no relationship between variables when there is none.

C) A Type II error occurs when a researcher concludes that there is no relationship between variables when there is one.

D) A Type I error occurs when a researcher concludes that there is a relationship between variables when there is one.

Ans: C Feedback: Researchers make a Type II error (not a Type I error) by accepting a null hypothesis that is, in fact, not true—i.e., concluding that there is no relationship when a relationship does exist between variables. Two of the response alternatives to this question are not errors at all—the researcher came to the correct conclusion.

A) .10 B) .05 C) .01 D) .001 Ans: D Feedback: For hypothesis testing, researchers select a level of significance, which is the probability of making a Type I error. The smaller the probability, the lower the risk, and in this example, the smallest value is .001.

A) .10 B) .05 C) .01 D) .001 Ans: B Feedback: An alpha of .05 is considered a minimum threshold acceptable in most situations for declaring that a result is statistically significant. An alpha of .10 is not sufficiently stringent (a 1 in 10 chance of a Type I error) and both .01 and .001 are more conservative than .05.

Ans: B Feedback:

Page 24

Setting the significance level (alpha) allows researchers to decide how much risk they are willing to accept that there will be a Type I error. Sample size affects the risk of Type II (not Type I) errors. Type I and Type II errors can occur with confidence intervals as well as with hypothesis tests. Researchers do not select sampling distributions; this is a function of which statistical test is used.

A 95% CI in parameter estimation corresponds to which alpha value in a hypothesis testing framework?

A) An alpha of .95 B) An alpha of .05 C) An alpha of .99 D) An alpha of .01 Ans: B Feedback: Levels of significance are analogous to the CI values—an alpha of .05 is analogous to the 95% CI, and an alpha of .01 is analogous to the 99% CI. By convention, the minimal acceptable alpha level is .05. An alpha of .01 is more stringent than an alpha of .05—just as a CI of .99 is more stringent than a CI of .95.

C) The 95% CI would have a range of 50 points.

Page 25

D) The risk of a Type I error would be 50%.

Ans: A Feedback: The probability of committing a Type II error can be estimated through power analysis. When power equals .80 (the standard criterion), the risk for a Type II error is 20%. For a given sample size, if the power was estimated to be .50, there would be a 50% probability of a Type II (not a Type I) error—that is, wrongly concluding that the null hypothesis was correct. A power analysis is not related to particular CI values or to the probability that results would be significant a specified percentage of the time.

A) The result is clinically meaningful.

B) The result does not contain a Type I or Type II error.

C) The result was consistent with the null hypothesis.

D) The obtained result likely was not the result of chance.

Ans: D Feedback: The term “statistically significant” means that results are not likely to have been due to chance at some specified level of probability. In this context, “significant” does not mean important or clinically meaningful. Any results could contain Type I or Type II errors—there is always some possibility of a statistical error. Statistically significant results indicate that the null hypothesis was rejected as probably being wrong.

46. Which of the following is not one of the steps involved in hypothesis testing?

A) Selecting the appropriate statistic to be used B) Specifying a level of significance C) Computing a test statistic D) Calculating the theoretical distribution for the test statistic Ans: D Feedback: Each statistical test can be used with specific kinds of data, but the overall hypothesis-testing process is similar for all tests: (1) selecting a test statistic, (2) specifying the level of significance, (3) computing a test statistic, (4) determining degrees of freedom, and (5) comparing the test statistic to a theoretical value.

B) values for the 95% CI. C) specified value of alpha.

D) specified value of the power criterion.

Ans: C Feedback: The value of alpha is the researcher’s criterion for statistical significance. The p value is the actual probability that the null hypothesis is false, and so the p value is compared to alpha. The p value is not compared to a theoretical distribution, CI values, or the power criterion.

Which of the following statistical tests would the researcher likely use?

A) An independent groups t-test B) A chi-squared test C) A dependent groups t-test D) A paired t-test Ans: A Feedback: In this example, the outcome variable is measured on a ratio scale; the mean number of weekly hours of exercise would be computed for men and women. The means of two separate groups of people are being compared, so an independent groups t-test would be appropriate. Paired (dependent groups) t-tests are used when the means for the same people are compared over time (e.g., before and after an exercise intervention).

B) accept the null hypothesis.

C) reject the null hypothesis.

D) use a different level of significance.

Ans: C Feedback:

Page 28

The absolute value of the calculated t (–2.50) is larger than the theoretical value of t (2.00). Thus, the null hypothesis can be rejected—that is, the group means are significantly different at p < .05. The value of the test statistic indicates that the null hypothesis is “improbable.” A different level of significance does not need to be selected—nor would that be appropriate once the results are “in.” Given the significant results, a Type II error (false negative) was not made.

Which of the following statistical tests was likely used to test group differences in anxiety scores?

A) t-Test B) ANOVA C) ANCOVA D) Chi-squared test Ans: B Feedback: Analysis of variance (ANOVA) is the statistical procedure used to test mean group differences for three or more groups.

A) Paired t-test B) Chi-squared test C) Analysis of variance (ANOVA) D) Repeated measures ANOVA Ans: D Feedback: Repeated measures ANOVA compares means for one or more groups at three or more different points in time. A paired t-test can be used to test mean differences for a group at two different points of data collection.

Which statistical test would the researcher likely use?

A) A chi-squared test B) A paired t-test C) ANOVA D) An independent groups t-test Ans: A Feedback: The chi-square (□2) test is used to test hypotheses about group differences in proportions or percentages. In this example, there are two groups (those with and without the dressing), and the dependent variable (dermatitis vs. no dermatitis) is a nominal-level variable for which percentages would be computed.

Pearson’s r, the most widely used correlation coefficient, is used to test whether there is a relationship between the two variables that are measured on an interval or ratio scale, as is the case in this example (here, both ratio-level variables). The chi-squared test and ANOVA involve comparisons of groups (proportions and means, respectively), and there are no groups in this example.

B) The alpha level was too conservative.

Page 32

C) The test had inadequate power.

D) A researcher did not use an appropriate conceptual framework.

Ans: C Feedback: When a researcher uses too small a sample, statistical tests are underpowered, and there is a risk of a Type II error (falsely concluding there is no relationship when there is one), as is likely to be the case in this example. There can never be too many degrees of freedom, as it is a function of sample size and a large sample improves statistical power. The α level of .05 is the least conservative level considered appropriate. A conceptual framework is unlikely to affect the results of a statistical test.

A) 4% B) 16% C) 40% D) Cannot be determined Ans: B Feedback: R, when squared, can be interpreted as the proportion of the variability in the outcome variable that is explained by the predictors. In predicting dental caries by candy intake, age, and income, an R of .40 results in an R2 = .16. Thus, the predictors accounted for 16% (not 4% or 40%) of the variation in dental caries.

C) Smoking status (smoker vs. nonsmoker) is measured at an acceptable level for use as either a predictor or a dependent variable in multiple regression.

D) The dependent variable in multiple regression can be measured at any measurement level.

Ans: B Feedback: Infant birth weight is on a ratio scale and could be used as either a predictor or a dependent variable in multiple regression. Dependent variables in multiple regression analysis should be measured on an interval or ratio scale, not on a nominal scale (e.g., smoking status).

Content validity is the extent to which the content of the items on a multi-item scale adequately captures the construct. Content validity, unlike criterion or construct validity, can be assessed with feedback from a panel of experts, who rate the relevance of items; the ratings are used to compute a content validity index (CVI).

What type of validity is being assessed?

A) Content validity B) Internal validity C) Criterion validity D) Construct validity Ans: C Feedback: Criterion validity is the extent to which the scores on a measure are a good reflection of a “gold standard,” which in this example is a biophysiological indicator of stress, wake-up salivary free cortisol levels. When scores on both measures are continuous, as in this example, Pearson’s r is the statistic used to evaluate criterion validity. Content validity and construct validity do not rely on a “gold standard” criterion. Internal validity concerns the adequacy of the research design for making causal inferences and is unrelated to measurement validity.

A) sensitivity.

B) specificity.

C) content validity.

D) ROC curve.

Ans: A Feedback: Sensitivity is a measure’s ability to identify a “case” correctly, that is, to screen in or diagnose a condition or trait correctly (the true positive rate). Specificity is the measure’s ability to identify non-cases correctly, that is, to screen out those without the condition (the true negative rate). ROC curves are sometimes used to plot sensitivity against specificity. Content validity is unrelated to an instrument’s ability to correctly identify a case.

Ans: B Feedback: Study results from statistical analyses are summarized in the results section of research articles that report quantitative studies. Researchers present their interpretations of the results (and their conclusions) in the discussion section.

Measures used in quantitative studies are described in the method section of the report. Even if researchers computed reliability statistics for measures they used, this would not usually be considered a “result” and would most often be reported in the method section (unless the study was a methodological one).

One of the most important interpretive tasks is to assess whether the results are correct—that is whether the results are credible and accurate. If the results are not credible, the remaining interpretive issues (meaning, magnitude, and so on) are not likely to be relevant.

Format: Multiple Choice Chapter: 14 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Analyze Difficulty: Moderate Integrated Process: Nursing Process Objective: 01 Page and Header: 242, Proxies and Interpretation 3. Which statement about interpretation is true?

A) In interpreting findings, researchers can assume that their inferences are accurate.

B) One aspect of the credibility of the results concerns their meaning.

C) Researchers use proxies to “stand in for” the constructs in which they are interested.

D) If results are deemed not to be credible, it is still important to understand their generalizability.

Ans: C Feedback: Constructs are linked to reality in a series of approximations, and each proxy affects the interpretation of the results. Researchers should not “assume” that their inferences are accurate—they must search for evidence in support of their inferences. Credibility and meaning are two separate interpretive issues. If results are not credible, there is little point in asking whether they are generalizable.

A) Admiring

Page 2

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

B) Accepting C) Skeptical D) Deferential Ans:C Feedback: It is prudent to approach the interpretation of results with a skeptical mindset, which involves critically scrutinizing and challenging the results until a conclusion about whether the results are “real” can be reached with confidence. A careful reader should think critically in reading a research report and demand methodological evidence that the results reflect the truth. Readers might admire a skillfully done study, and they might come to accept that the research evidence is valid, but should first carefully scrutinize how the study was done. Deference is never needed—readers should not “defer” to the researchers without thinking critically about how they addressed their research questions.

B) Evaluating the credibility of a study involves a careful assessment of methodological decisions.

C) Support of a researcher’s hypothesis through statistical testing offers proof of its veracity.

D) A correlation between two variables indicates that the independent variable caused the outcome.

Ans: B Feedback: A credibility assessment requires a careful analysis of the study’s methodological and conceptual limitations and strengths. Statistical results do not always have direct meaning but, rather, require interpretation. Empirical evidence supporting research hypotheses never constitutes proof of their veracity. Correlation between two variables does not prove causation.

A) To document the flow of people into and out of a study sample B) To summarize results from statistical analyses C) To document the progression of research activities in a study D) To chart the flow of the researcher’s methodological decisions Ans: A Feedback: Publication guidelines called the Consolidated Standards of Reporting Trials (CONSORT) are used by major medical and nursing journals. CONSORT flow charts are used to help readers understand the results of researchers’ efforts to recruit, enroll, and retain study participants. CONSORT flow charts do not summarize study findings, the progression of research activities, or the flow of researchers’ methodological decisions.

The population construct would be college students in the United States. The construct involves students, not universities. There is nothing to suggest that the population construct was nursing students. “Cooperative students at the University of Connecticut” is the actual sample, not the population construct.

B) Inappropriate eligibility criteria could affect a study’s construct validity.

C) Attrition would have no effect on a study’s generalizability.

D) Attrition would have no effect on a study’s internal validity.

Ans: B Feedback: Construct validity is not simply about measurements; it is about making inferences about all types of constructs, and so researchers must make sure that the eligibility criteria are appropriate for the population construct—that is, the target population of interest. Attrition could have negative effects on both the internal validity and the external validity (generalizability) of a study.

Ans: D Feedback: An important job for researchers is to eliminate, reduce, or control biases through the use of rigorous study methods. Researchers do not adopt rigorous study methods to prevent inferences or eliminate the need for a CONSORT flow chart.

Strong methods are used in the hopes of rejecting the null hypothesis.

Which of the following is an important concept that links efforts at corroboration to the credibility of research results?

A) Replication B) Confidence intervals C) Nonresponse D) The null hypothesis Ans: A Feedback: Credibility is enhanced when results can be corroborated, and replication is a key concept. If results replicate earlier findings, that is an important form of corroboration. In multisite studies, the replication of results across different sites also offers corroboration. Confidence intervals, nonresponse, and the null hypothesis are unrelated to efforts to support credibility through corroboration.

A) The range of the measured values in the sample reported in the research report B) The probability that the results were obtained in error C) The range of values within which the population value probably lies D) The likelihood that the results will be useful in practice Ans: C Feedback: A p value offers information about whether the study results are “real” and replicable, but confidence intervals (CIs) communicate information about the range of values within which the population parameter probably lies. CIs provide no information about the range of measured values in the sample, nor about the practical utility of the results.

A) Correlation does not prove causation.

B) Causation does not prove a correlation.

C) Study results can prove that hypotheses are correct.

A) The Relationship Between Infant Birth Weight and Subsequent Behavior Problems B) Factors Associated With Medication Adherence in Children C) The Impact of Parenting Style on Adolescents’ Sexual Risk-Taking Behavior D) The Association Between Spiritual Well-Being and Quality of Life in the Elderly Ans: C Feedback: The word impact is a “loaded” word that implies a causal relationship. In this example, it suggests that parenting style causes different risk-taking behavior in adolescents. There may be a causal relationship, but it would be difficult to mount a persuasive argument in this study, which is necessarily nonexperimental: Parenting style could not be randomized to different children to assess the impact on subsequent risk-taking behavior.

A positive result is one in which a hypothesis was supported by the data, as in the case where the researcher predicted a negative relationship between two variables.

A positive correlation does not mean that the researcher hypothesized that the relationship would be positive. In some cases, a positive correlation could reflect a result opposite to what the researcher hypothesized.

A) A nonsignificant result indicates that the sample size was too small.

B) A nonsignificant result indicates that the null hypothesis was correct.

C) A nonsignificant result means that a Type II error occurred.

D) A nonsignificant result is inconclusive.

Ans: D Feedback: Failure to reject a null hypothesis can occur for many reasons, and the real reason is usually impossible to discern—thus, a nonsignificant result is inconclusive. One possibility is that the sample was too small; another is that the null hypothesis was correct—but this cannot be known with certainty. If the null hypothesis was correct, then a Type II error would not have been committed.

C) Statistically significant results that are the opposite of what was hypothesized are likely the result of a Type II error.

D) Statistically significant results that are the opposite of what was hypothesized are likely wrong.

Ans: B Feedback: When significant findings are opposite to what was hypothesized, researchers need to carefully consider their own methods, findings from earlier studies, and alternative theoretical perspectives. The findings should not be ignored—they need to be carefully interpreted. The results are not especially likely to be “wrong,” and they cannot reflect a Type II error, which only occurs when the results are not significant.

A nurse researcher tested the effectiveness of a foot massage on geriatric patients’ pain levels. One study participant, Mr. Evans, had a pain score of 80 (on a scale from 0 to 100) before the massage and a pain score of 65 at follow-up. What would a score of 15 for Mr. Evans be called?

A) His targeted score B) His score at the next follow-up C) His baseline score D) His change score Ans: D Feedback: A change score is the difference between a baseline score (here, 80) and a followup score (here, 65), and so Mr. Evan’s change score is 15, indicating some improvement in his pain level. There is no way to know what Mr. Evan’s next follow-up score would be. A pain score of 15 is very low and is perhaps lower than could be considered realistic for a targeted score if the patient’s baseline pain score was 80.

Ans: A Feedback:

Page 12

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Dozens of approaches to operationalizing clinical significance at the individual level exist, but they all involve establishing a benchmark (a threshold) that designates a value that would be considered clinically important. Some approaches involve scores based on distributional characteristics of a measure and yet others involve assessments of change score reliability, but these are not true of all approaches to operationalizing clinical significance at the individual level. Effect size indexes are used primarily for group-level clinical significance.

Which of the following is often used to create a threshold in evaluating clinical significance at the individual level?

A) Confidence intervals (CIs) B) Number needed to treat (NNT) C) d values D) Minimal important change (MIC) Ans: D Feedback: The minimal important change (MIC) is a benchmark for the smallest amount of change in a person’s score on an outcome that would be considered clinically important. Values of d, confidence intervals (CIs), and number needed to treat (NNT) are often used to interpret clinical significance at the group level.

Which of the following statements about the minimal important change (MIC) is true?

Page 13

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

A) The traditional approach to establishing the MIC is to use the recommendation of a consensus panel of experts.

B) The value of the MIC usually is 3 points on a change score.

C) The distributional approach to establishing the MIC uses a threshold of p values in a distribution of change scores.

D) The MIC can be useful in interpreting clinical significance at the group level.

Ans: A Feedback: Consensus panels are the traditional approach to establishing the MIC, although other methods have become more popular in recent years. Another approach is based on distributional characteristics, but this approach does not use p values for a distribution of change scores to establish a threshold. The actual value of the MIC varies from outcome to outcome and is not a fixed value of 3.0 (or anything else).

MICs are useful for interpreting individuals’ change scores, not for interpreting average change scores of a group.

For outcomes that have an established MIC threshold, what type of analysis is possible for detecting group differences in clinically significant change for individuals in the group?

A) A power analysis B) A distributional analysis C) A responder analysis D) An effect size analysis Ans: C Feedback: Study participants can be classified as responders or nonresponders to an intervention or an influence based on their change scores relative to an established MIC threshold. Researchers can then undertake a responder analysis that compares the percentage of responders in study groups (e.g., those in the intervention and those in the control group).

A) Mastering the standard procedures for analyzing qualitative data B) Dealing with the shortage of narrative materials to analyze C) Reducing extensive amounts of data for reporting purposes D) Deducing particulars from general concepts Ans: C Feedback: Qualitative data analysis is challenging, for several reasons. One challenge concerns the fact that qualitative analysts must organize and make sense of hundreds or even thousands of pages of narrative materials (there is usually no shortage of data)—and the information must be reduced to essentials for reporting purposes.

There are no standard procedures for qualitative analysis. Qualitative analysis is an inductive (not deductive) process that involves inducing general concepts and theories from the particular details in the data.

A) Narrative materials tend to be linear, which simplifies the coding process.

B) Qualitative researchers typically develop a coding scheme before they collect their data.

C) CAQDAS is used to organize and retrieve qualitative data.

D) CAQDAS is preferred by virtually all qualitative researchers because it allows analysts to get closer to their data.

Ans: C Feedback: Computer-assisted qualitative data analysis software (CAQDAS) removes the work of cutting and pasting pages of narrative material and is used to organize and retrieve coded data; the software cannot actually do the coding. Some qualitative researchers avoid CAQDAS, believing that manual methods allow them to get closer to their data. Narrative materials usually are not linear, a fact that complicates coding. A preliminary coding system is sometimes drafted before data collection, but typically qualitative analysts develop coding schemes based on a scrutiny of actual data.

A) Qualitative data analysis is reductionist in nature.

B) To be valid, a theme identified in the data must be universal across participants.

C) Qualitative analysts search for commonalities across participants but also look for variation and patterns.

D) The underlying process of qualitative data analysis is deduction.

A) Content analysis is used by grounded theory researchers.

B) In purely descriptive qualitative studies, the focus is typically on the latent content of the text.

C) In a qualitative content analysis, the data do not have to be coded.

D) In a content analysis, a meaning unit is the smallest segment of a text that contains usable information.

Ans: D Feedback: A meaning unit consists of the words, sentences, or paragraphs that have meaningful and recognizable information. To manage and gain access to qualitative data, content analysts, like other qualitative analysts, usually code their data. In descriptive qualitative studies, researchers typically focus on manifest content (what the text actually says), although they may also be interested in the latent content (what the text talks about, which requires interpretation). Content analysis is not associated with grounded theory.

Ans: D Feedback:

Page 10

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

The basic outcome of the various approaches to descriptive phenomenology is the description of the essential nature of an experience, often through the identification of essential themes. The use of artistic sources for inspiration is sometimes a feature of interpretive, but not descriptive, phenomenology. Identifying core categories occurs in grounded theory, not phenomenological, data analysis.

Intersubjective agreement among judges is advocated by one phenomenologist (van Kaam), but it is not the fundamental feature in descriptive phenomenology.

According to the viewpoint of one leading phenomenologist, it is inappropriate to go back to study participants to validate a preliminary thematic analysis. Which phenomenologist had this view?

A) Colaizzi B) Giorgi C) Glaser D) Strauss Ans: B Feedback: Phenomenologists differ in their views on validating themes by asking study participants to provide feedback about preliminary results. Giorgi’s view is that it is inappropriate either to return to participants to validate findings or to use external judges to review the analysis. Colaizzi’s method calls for a validation of results by querying study participants. Glaser and Strauss are not phenomenologists.

A leading phenomenologist held the view that qualitative researchers should glean experiential information about a phenomenon from artistic sources (e.g., poetry, paintings). Which phenomenologist had this view?

A) Colaizzi B) Van Kaam C) Giorgi D) Van Manen Ans: D Feedback: In addition to identifying themes from participants’ words, van Manen called for gleaning information from artistic sources. He believed that literature, music, painting, and other art forms offer a wealth of experiential information that can increase researchers’ insights. Colaizzi, van Kaam, and Giorgi were descriptive phenomenologists who did not explicitly promote the use of artistic sources to supplement text from interviews.

A researcher conducted a phenomenological study about the experience of losing one’s eyesight to macular degeneration, using one of van Manen’s analytic approaches. The researcher pulled out significant statements from interview transcripts that seemed essential to the participants’ experience. Which of van Manen’s methods did the researcher use?

A) Holistic B) Selective C) Detailed D) Interpretive Ans: B Feedback: Van Manen’s analytic method included three approaches. In the selective approach, researchers highlight or pull out statements or phrases that seem essential to the experience under study, as in this example. In the holistic approach, researchers view the text as a whole and try to capture its meanings. In the detailed approach, researchers analyze every sentence. Van Manen’s method does not include an “interpretive” approach.

Benner’s approach, which is sometimes used in hermeneutic analysis, involves a search for “strong instances of concerns or ways of being in the world.” Which term is associated with these “strong instances”?

A) A hermeneutic circle B) A holistic approach C) A paradigm case D) An exemplar Ans: C Feedback: Benner’s approach for hermeneutic analysis involves three interrelated processes: the search for paradigm cases, thematic analysis, and analysis of exemplars. As defined by Benner, paradigm cases are “strong instances of concerns or ways of being in the world;” these cases are used early in the analytic process to gain understanding. Van Manen’s analytic method (not Benner’s) included a holistic approach. A hermeneutic circle is a term used in hermeneutics regarding a broad process used to reach understanding.

In Glaserian grounded theory, substantive coding involves open and selective coding. What are open codes?

A) Codes that capture a basic social process B) Codes that capture what is going on in the data C) Codes that encapsulate relationships among the substantive codes D) Codes that focus on a core category Ans: B Feedback: Substantive coding includes open coding, which is designed to capture what is going on in the data. Open coding is used in the first stage of constant comparison and may be the actual words used by the study participants. Open codes do not focus on a core category, nor do they encapsulate relationships among substantive codes. A basic social process is one type of core category and is not captured in preliminary open coding.

B) Level I code.

C) theoretical code.

D) BSP. Ans: A Feedback: In Glaserian grounded theory, the core category is a pattern of behavior that is relevant and/or problematic for participants. One type of core category is a basic social process (BSP) that evolves over time in two or more phases. All BSPs are core variables, but not all core variables are BSPs.

C) The debate about using the term “validity” among qualitative researchers has been resolved.

D) There is a broad consensus among qualitative researchers regarding what the quality criteria for evaluating qualitative research should be.

Ans: A Feedback: There are many debates about quality nomenclature and criteria for qualitative research, one of which is whether generic standards or tradition-specific standards should be adopted. No consensus on quality criteria has been achieved. The views about “validity” have not been resolved; differences of opinion remain and are likely to persist.

4. Which of the following statements about quality criteria in qualitative research is true?

A) Compared to quantitative researchers, qualitative researchers are less focused on assessing quality in their research designs and methods.

B) No criterion in qualitative research is comparable to the positivists’ criterion of internal validity.

C) With regard to qualitative research criteria, nothing is considered the “gold standard.”

D) There is no common vocabulary for quality criteria in qualitative inquiry.

Ans: D Feedback: Debates about quality criteria for qualitative research abound, and one result is that there is no common, universally accepted vocabulary about what criteria to use, or how to define those criteria. Lincoln and Guba established criteria that are considered the “gold standard” for qualitative research, but not all qualitative researchers agree with their recommendations. Nevertheless, qualitative researchers are as eager as quantitative researchers to produce high-quality research. One of Lincoln and Guba’s criteria (credibility) is a parallel to internal validity.

A) Method triangulation B) Investigator triangulation C) Theory triangulation D) Data triangulation Ans: A Feedback: Triangulation is the process of using multiple referents to draw conclusions about what constitutes the truth. Method triangulation involves using multiple methods of data collection about the same phenomenon—here, the use of both interviews and diaries as data sources. This example does not illustrate investigator, data, or theory triangulation.

A nurse researcher conducted a qualitative study on contraceptive decision making among youth. She interviewed youth in adolescent health clinics in four different communities. Which quality-enhancement strategy is described in this example?

A) Persistent observation B) Prolonged engagement C) Data triangulation D) Reflexivity Ans: C Feedback: Data triangulation refers to the use of multiple data sources for the purpose of validating conclusions. In this example, the nurse researcher used a type of data triangulation called space triangulation, which involves collecting data on the same phenomenon in multiple sites to assess cross-site consistency. This example does not illustrate reflexivity, persistent observation, or prolonged engagement— although these strategies may also have been used in the study.

Which quality-enhancement strategy was the researcher using?

A) Maintaining an audit trail B) Undertaking a member check C) Enhancing persistent observation D) Ensuring adequate triangulation Ans: A Feedback: In this example, the researcher was developing an audit trail—a systematic collection of materials and documentation that would allow an independent auditor to come to conclusions about the data. The researcher may also have used other quality-enhancement strategies, such as persistent observation, triangulation, and member checking, but these strategies were not described in the example.

Which quality-enhancement strategy was the researcher using?

A) Data triangulation B) Person triangulation C) Space triangulation D) Investigator triangulation Ans: D Feedback: Investigator triangulation refers to the use of two or more researchers to make coding, analysis, and interpretation decisions. Other forms of triangulation may have been used in this study, but such strategies were not described in the example.

In qualitative research, investigator triangulation is comparable to which quantitative research concept?

A) Content validity B) Construct validity C) Interrater reliability D) Internal consistency Ans: C Feedback:

Page 13

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Investigator triangulation is conceptually analogous to interrater (or intercoder/interobserver) reliability in quantitative studies; in both cases, two independent people draw conclusions about the data, which are then compared.

Content validity refers to the degree to which items in an instrument actually measure the intended concept. Construct validity is the extent to which evidence about study particulars supports inferences about higher order constructs. Internal consistency in quantitative research refers to the degree to which subparts of a scale or instrument (the items) measure the same attribute. Investigator triangulation is unrelated to content validity, construct validity, or internal consistency.

Why do researchers search for and incorporate disconfirming evidence in a qualitative analysis?

A) To eliminate negative cases from data analysis B) To refine a conceptualization or theory C) To confirm saturation of the data D) To formulate a conclusion based on multiple sources of data Ans: B Feedback: Searching for disconfirming evidence is a verification procedure that involves challenging an explanation or category that has emerged early in data analysis. It occurs concurrently with data collection and analysis and its goal to continuously refine a conceptualization, hypothesis, or theory. Eliminating negative cases is the opposite of incorporating disconfirming evidence. Saturation of data occurs when data collection yields redundant information. Triangulation is the process of using multiple referents to draw conclusions about what constitutes the truth.

A) Are there coding errors?

B) Are there possible errors of interpreting the data?

C) Is the description sufficiently thick?

D) Were interviews accurately transcribed?

Ans: B Feedback: In peer debriefing sessions, researchers are exposed to the searching questions of other experts. A major issue in peer debriefings is whether the researchers have developed a powerful and compelling interpretation of their data. Peer debriefings do not focus on coding or the accuracy of transcriptions, and “thick description” is not yet an issue because a report on the findings has typically not yet been written.

Format: Multiple Choice Chapter: 16 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Understand Difficulty: Moderate Integrated Process: Teaching/Learning Objective: 03 Page and Header: 283, Inquiry Audits 25. The maintenance of good, thorough documentation and a decision trail is especially critical for: A) member checks.

B) thick description.

C) negative case analyses.

D) inquiry audits.

Ans: D Feedback: An inquiry audit involves a formal scrutiny of actual data and relevant supporting documents by an independent auditor. Thick description, member checks, and negative case analyses are all strategies for enhancing the quality of qualitative inquiries, but they are not a component in inquiry audits, and they do not involve the maintenance of an audit trail.

Several strategies can be used to enhance transferability in qualitative studies.

Which is one of those strategies?

A) Inquiry audits B) Member checking C) Thick description D) Method triangulation Ans: C Feedback: Thick description refers to a rich, thorough, and vivid description of the research context and the people who participated in the study. Transferability cannot occur unless investigators provide detailed information to permit judgments about contextual similarity. Member checking, inquiry audits, and method triangulation are all strategies for enhancing the quality of qualitative inquiries, but they are not strategies that specifically address transferability.

Which of the following is not an interpretive dimension for qualitative studies?

A) The meaning of qualitative results B) The precision of qualitative results C) The importance of qualitative results D) The implications of qualitative results Ans: B Feedback: Precision is an important interpretive dimension in quantitative—but not qualitative—research. Interpretation in qualitative studies encompass such dimensions as the meaning of the results, their importance, and their implications.

A) Investigator triangulation in qualitative research provides proof that interpretations are correct.

B) Qualitative analyses test hypotheses generated from quantitative research.

Page 17

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

C) Interpretation and analysis of qualitative data typically occur simultaneously.

D) Qualitative researchers should resist the temptation of being creative in analyzing their data.

Ans: C Feedback: Interpretation and analysis of qualitative data typically occur virtually simultaneously, in an iterative and reciprocal process. Interpretation in qualitative studies sometimes yields hypotheses that can be tested in more controlled quantitative studies—not the other way around. Creativity can play an important role in uncovering meaning in the analysis of qualitative data. Investigator triangulation strengthens credibility, but it does not provide “proof” that interpretations are correct.

Which barrier do qualitative researchers face in demonstrating the trustworthiness of their studies to readers?

A) Page restrictions in journals B) Readers’ lack of skills in understanding trustworthiness C) Peer reviewers’ focus on study findings rather than methods D) Absence of disconfirming evidence Ans: A Feedback: Adhering to page limitations imposed by journals inevitably reduces the amount of thick description and verbatim accounts that can be reported in qualitative research reports, and so both authenticity and transferability can be affected. Failure to find disconfirming evidence enhances, rather than diminishes, trustworthiness. Readers’ skills do not constitute a barrier to demonstrating trustworthiness, and peer reviewers are typically very focused on critically appraising methodological decisions, including decisions affecting trustworthiness.

Which statement about systematic reviews is true?

A) “Systematic review” is another name for a literature review.

B) Systematic reviews follow many of the same “rules” as those for primary studies.

C) All systematic reviews of quantitative studies involve a meta-analysis.

D) All systematic reviews of quantitative studies involve a metasynthesis.

Ans: B Feedback: What distinguishes a systematic review from a literature review is that systematic reviews follow orderly sampling, data collection, and data analysis procedures, much as is true in a primary study (an original research investigation). Not all quantitative systematic reviews involve a meta-analysis, and none of them would involve a metasynthesis.

Ans: A Feedback:

Page 1

Systematic reviews are a cornerstone of evidence-based practice (EBP), which relies on rigorous integration of research evidence on a topic. Meta-analyses (a particular method of analyzing data from a systematic review) of randomized controlled trials (RCTs) are at the pinnacle of traditional evidence hierarchies but are not a “cornerstone.” Primary studies play a role in EBP, but when several similar studies are integrated, the evidence is typically stronger.

B) results from primary qualitative studies.

C) results from primary quantitative studies.

D) prior systematic reviews.

Ans: C Feedback: The unit of analysis in a meta-analysis is a result from a primary quantitative study (not a primary qualitative study). The unit of analysis in a primary study is an individual study participant. Prior systematic reviews are not the unit of analysis in a meta-analysis.

A) Meta-analysis is less work than a narrative systematic review.

B) Meta-analysis is feasible with a wider range of research questions than a narrative systematic review.

Page 2

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

C) Meta-analysis integrates information in a more objective manner than in a narrative integration.

D) Meta-analysis requires a smaller sample of primary studies than a narrative systematic review.

Ans: C Feedback: For systematic integration of quantitative evidence, meta-analysis offers the advantage of objectivity. Decision rules are made explicit, and the actual integration is statistical, not based on the researchers’ judgments. It is not true that meta-analyses are less work than a narrative systematic review or that they require smaller samples. Narrative reviews can be undertaken for any research question, but this is not the case for meta-analyses.

In the evolving field of evidence integration, special types of review are emerging. Which of the following is a type of review that integrates findings from two or more systematic reviews?

A) Scoping reviews B) Rapid reviews C) Mixed studies reviews D) Umbrella reviews Ans: D Feedback: When multiple systematic reviews on a topic have been conducted, an umbrella review that integrates studies from the previous systematic reviews can be conducted. A rapid review is a streamlined and less rigorous type of systematic review. A mixed studies review integrates findings from qualitative, quantitative, and mixed method studies. A scoping review is often undertaken to assess the feasibility of conducting a systematic review for a specific research question.

A) All of the primary studies must have statistically significant results.

B) All of the primary studies must have clinically significant results.

C) The results among the primary studies in a meta-analysis must all be consistent.

D) There needs to be a sufficiently large number of relevant primary studies.

Ans: D Feedback: One criterion for a meta-analysis concerns whether there is a sufficient base of knowledge for statistical integration. If there are only a few studies, it is not sensible to compute an “average” effect. The results from a primary study do not have to be statistically or clinically significant to be included in a meta-analysis. The results from primary studies do not have to be totally consistent—although highly conflicting results may suggest that a meta-analysis is inappropriate.

A) Results among studies are highly conflicting.

B) Research questions across studies are nearly identical.

C) There is a large pool of primary studies.

D) The independent variable is consistent across studies.

Ans: A Feedback: When the same hypothesis has been tested in multiple studies and the results are highly conflicting, meta-analysis is likely inappropriate. Another basic criterion is that the research question being addressed should be nearly identical across studies (including the independent and dependent variables). Finally, there must be

B) “What is the experience of caring for a patient with dementia?”

C) “What factors put people at risk for dementia?”

D) “What percentage of adults aged 60 years and older have dementia?”

Ans: A Feedback: Only one question among the four options specifies PICO components for a systematic review: What is the effect of music (the influence or intervention, I), compared to no music (the comparator or C) on agitation (the outcome, O), in patients with dementia (the population or P).

Ans: B Feedback: A scoping review is a preliminary investigation that clarifies the range and nature of the evidence base. Scoping reviews can suggest strategies for a full systematic review and can also indicate whether statistical integration (a meta-analysis) is feasible. The other responses have no relevance to efforts to refine a research question for a systematic review.

A) The primary studies must have had funding.

B) The primary study reports must be written in English or Spanish.

C) The primary studies must have been based on pilot studies.

D) The primary studies must be within the grounded theory tradition.

Ans: B Feedback: Studies are often excluded from a systematic review if they are written in a language that the review team cannot read. There is no legitimate reason (in normal circumstances) to exclude unfunded studies or studies that are not based on a pilot study. Grounded theory studies are qualitative and would not be included in a quantitative systematic review.

A) Statistical heterogeneity of results across primary studies is rare.

B) Only published research reports are included in meta-analyses.

C) Low-quality studies are excluded from meta-analyses.

D) If statistical heterogeneity is anticipated, subgroup analyses to explore variation in effects are often planned.

Ans: D Feedback: If it is expected that there will be variation in effects (statistical heterogeneity) associated with patient characteristics, site characteristics, or study methodology, subgroup analyses are often planned during the design phase of the project.

Statistical heterogeneity is almost inevitable—it is certainly not rare. Low-quality studies and unpublished studies are often (but not always) included in metaanalyses. The effects of study quality are, however, often explored in the analyses.

B) studies not published in English will be underrepresented.

C) studies with weak effects will be overrepresented.

D) studies with biases will be overrepresented.

Ans: A Feedback: The grey literature—studies that have not been published—is disproportionately composed of studies with nonsignificant findings. This publication bias means that when the grey literature is excluded, effect size estimates tend to be inflated. The risk is not that non-English reports will be underrepresented or that studies with biases or weak effects will be overrepresented.

A) The best way to measure primary study quality is to rate each study on a scale from 0 to 10.

B) The Cochrane Handbook recommends coding primary studies for the presence/absence of key features relating to the risk of bias.

C) Researchers who are experts do not need to do an interrater reliability assessment for evaluations of primary study quality.

Ans: B Feedback:

Page 8

The authors of the Cochrane Handbook recommend a domain approach, as opposed to a scale approach. Individual methodological features are given a separate rating or code for each study (e.g., whether or not blinding was used). There are dozens of different scales for assessing study quality, and no consensus about which is preferred. Interrater reliability is strongly recommended regardless of the metaanalysts’ expertise. If two raters disagree, there should be a discussion until consensus is achieved, or a third rater should help to resolve the disagreement.

C) Pearson’s correlation coefficient (r) D) The odds ratio (OR) Ans: B Feedback: An intensity effect size can be developed in metasyntheses, not in meta-analyses.

Meta-analyses depend on the calculation of an effect size index that encapsulates the relationship between the independent variable and the outcome variable in each study. The most common effect size index is Cohen’s d; others include the odds ratio (OR), and (in nonexperimental studies) Pearson’s r.

A meta-analyst sought to estimate the effectiveness of interventions designed to improve mental health outcomes for family members who have a relative in palliative care. The primary studies compared participants in an intervention group with those in a control group in terms of their level of depression, as measured on multi-item self-report scales. Which effect size index would be used?

A) Cohen’s d (standardized mean difference) B) The relative risk (RR) index C) Pearson’s r D) The odds ratio (OR) Ans: A Feedback: This is a two-group situation with a continuous outcome variable (level of depression), which calls for the calculation of Cohen’s d (sometimes called the standardized mean difference). The other indexes are used to estimate effect size in different situations. If the outcome is dichotomous rather than continuous, the OR or RR could be used; if the independent variable is continuous rather than nominal level, Pearson’s r might be appropriate.

A meta-analyst addressed the question of whether mindfulness-based interventions were effective in reducing anxiety in patients with cancer and found high levels of statistical heterogeneity (i.e., significant variation of effects across studies). What should the meta-analyst do?

A) Abandon efforts to undertake a meta-analysis.

B) Use a fixed effects analytic model.

C) Use a random effects analytic model.

D) Ignore the heterogeneity.

Ans: C Feedback: Statistical heterogeneity (diversity in effects across studies) is a major issue in meta-analysis. When results are varied, meta-analysts should use a random effects statistical model rather than a fixed-effects model. Heterogeneity should not be ignored, but it does not necessarily lead to an abandonment of the meta-analysis unless heterogeneity is extreme.

D) Using a forest plot to plot study quality against the effect size index Ans: B Feedback: Quality assessments are sometimes used to exclude weak studies from systematic reviews, but they can also be used in sensitivity analyses to evaluate whether including or excluding weaker studies changes conclusions. Quality of the studies should not be ignored because primary study rigor affects the quality of the evidence.

Which of the following statements about GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) is true?

A) GRADE is used to summarize reviewers’ conclusions about how much confidence can be placed in results for some outcomes in a review.

B) GRADE ratings are done for all of the outcomes in a systematic review, taken cumulatively.

C) GRADE ratings are on a 10-point scale, from 1 = low confidence to 10 = high confidence.

D) Systematic reviewers using GRADE first rate their level of confidence and then make recommendations in clinical guidelines.

Ans: A Feedback: Systematic reviewers use GRADE to summarize how much confidence can be placed in the in results of the systematic review, for a select number of clinically important outcomes evaluated one at a time. Reviewers do not use GRADE to make clinical guideline recommendations—groups of clinicians do that. GRADE ratings are high, moderate, low, or very low and are not on a 10-point scale.

A) Qualitative systematic reviews do not include studies from multiple qualitative traditions.

B) Aggregative qualitative reviews are usually referred to as metasyntheses.

C) Interpretive qualitative reviews are more likely to be called qualitative evidence syntheses than aggregative reviews.

D) Most systematic qualitative reviews have elements of both aggregation and interpretation.

Ans: D Feedback: Qualitative systematic reviews can often be considered either “interpretive” or “aggregative,” but most such reviews have elements of both aggregation and interpretation. Many qualitative systematic reviews combine findings from diverse qualitative traditions. Interpretive, not aggregative, reviews are usually referred to as metasyntheses, and aggregative, not interpretive, reviews are increasingly called qualitative evidence syntheses (QES).

Most metasyntheses involve an evolving and transformational process, and so the specific research question might not be known at the outset. It is prudent to have at least two reviewers involved in a metasynthesis, to enhance the trustworthiness of the findings. Dissertations are an excellent source of data for a metasynthesis because they often have richer and more detailed information than a journal article.

Metasynthesis is not akin to concept analysis.

Which is true about researchers conducting metasyntheses?

A) They use only primary studies from peer-reviewed journals in the analysis.

B) They perform little advance planning, as it is not needed in qualitative research.

C) They sample primary studies at random.

D) They often evaluate study quality using a 10-question assessment tool from the Critical Appraisal Skills Programme (CASP) from the United Kingdom.

Page 15

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Ans: D Feedback: Many metasynthesists use the CASP quality appraisal tool in evaluating primary study quality. Like a quantitative systematic review, a metasynthesis requires considerable advance planning. Metasynthesists include both published and unpublished primary studies—and sometimes prefer unpublished studies (e.g., dissertations) because they provide richer detail. Metasynthesists do not sample primary studies at random. They may sample exhaustively (all the studies they can find) or may sample purposively.

28. In the Noblit and Hare approach to integrating qualitative findings, one phase involves: A) computing an intensity effect size.

B) computing a frequency effect size.

C) doing a reciprocal translation analysis.

D) undertaking a meta-summary.

Ans: C Feedback: The fifth phase in the Noblit and Hare approach involves translating the qualitative studies into one another. Reciprocal translation analysis involves exploring and explaining similarities and contradictions between studies and is not unlike a constant comparative process. Noblit and Hare’s meta-ethnographic approach does not involve computing intensity or frequency effect sizes, nor does it involve doing a meta-summary.

One approach to systematically integrating qualitative findings distinguished qualitative reports that are “summaries” and ones that are “syntheses;” the researchers argued for including only “syntheses” as the primary studies in a metasynthesis. Which scholars are associated with this approach?

A) Sandelowski and Barroso B) Glaser and Strauss C) Thorne and Morse D) Noblit and Hare Ans: A Feedback: Sandelowski and Barroso describe qualitative reports as summaries if the findings are descriptive synopses of the qualitative data, without conceptual reframing.

Syntheses are findings that are more interpretive and explanatory and that involve conceptual or metaphorical reframing. Sandelowski and Barroso have argued that only syntheses should be used in a metasynthesis. Thorne and Morse, Glaser and Strauss, and Noblit and Hare are all notable qualitative researchers, but they are not associated with the distinction between summaries and syntheses.

A metasynthesist calculated manifest effect sizes in a meta-summary of qualitative studies on adolescent mothers’ experience of being homeless. The researcher divided the number of unduplicated reports that contained the theme of “enduring abuse” by all unduplicated reports in the analysis. What type of effect size is this?

A) An intensity effect size B) A frequency effect size C) A reciprocal effect size D) A refutational effect size Ans: B Feedback: A frequency effect size, which indicates the magnitude of the findings, is the number of reports with unduplicated information that contain a given finding, divided by all unduplicated reports. Another type of manifest effect size is the intensity effect size, which indicates the concentration of findings within each report. There are no effect sizes called “reciprocal” or “refutational.”

A) Rating confidence in the findings using ConQual B) Integrating findings using reciprocal translation analysis C) Collapsing two or more categories into synthesized findings D) Collapsing findings to compute frequency effect sizes Ans: C Feedback: The JBI approach to data analysis is a three-step process, the third of which is to develop synthesized findings that encompass two or more categories. Frequency effect sizes are not computed in meta-aggregation, nor is reciprocal translation analysis used to integrate findings. ConQual is used after the data analysis and synthesis stage is completed to assess confidence in the findings.

Most definitions of evidence-based practice (EBP) call for the integration of best research evidence with clinical expertise and: A) patient preferences and values.

B) well-worded clinical questions.

C) systematic reviews.

D) rankings on evidence hierarchies.

Ans: A Feedback: Evidence-based practice, according to most definitions, call for integrating best evidence from research with clinical expertise and patient preferences and values.

The evidence itself is often derived from systematic reviews, which can be retrieved by asking well-worded clinical questions. The rigor of evidence is sometimes graded according to a ranking system on evidence hierarchies.

Research utilization is a process that begins with which of the following?

A) A clinical problem that needs to be solved B) A problem-focused trigger C) A finding from existing research D) A well-worded clinical question Ans: C Feedback:

Page 1

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Research utilization (RU) is the use of an existing finding from research in a practical application that is unrelated to the original research. Evidence-based practice (EBP) is a broader concept than RU, and EBP efforts can begin with an existing finding (also called a knowledge-focused trigger in some EBP models), or with a problem to be solved (a problem-focused trigger). Asking a well-worded clinical question is often the first step in the EBP process.

Format: Multiple Choice Chapter: 18 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Understand Difficulty: Moderate Integrated Process: Nursing Process Objective: 01 Page and Header: 311, Evidence-Based Practice and Related Concepts 3. Which of the following statements is true?

A) The learning strategy called evidence-based medicine was initiated in the United States by an epidemiologist.

B) The Cochrane Collaboration, with centers around the world, plays a major role in preparing and disseminating systematic reviews.

C) Research utilization (RU) currently is a more prominent concept than evidencebased practice (EBP).

D) EBP activities in nursing are always undertaken by teams of nurses.

Ans: B Feedback: The international Cochrane Collaboration was founded in the United Kingdom based on the work of epidemiologist Archie Cochrane. The collaboration aims to support health care providers by disseminating systematic reviews of the effects of health care interventions. The learning strategy called evidence-based medicine was developed at the McMaster Medical School in Canada by Dr. David Sackett.

Research utilization efforts have largely been superseded by EBP. Individual nurses as well as teams of nurses (and interdisciplinary teams) can engage in EBP activities.

Which argument is used by advocates of EBP? Page 2

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

A) EBP provides an excellent basis for lobbying for health research funding.

B) EBP offers a good framework for self-directed lifelong learning.

C) EBP activity helps to build professional credentials.

D) EBP promotes the elimination of health disparities.

Ans: B Feedback: EBP encourages ongoing learning to discover “best evidence”—and new evidence is constantly emerging through expanded research efforts. Thus, EBP promotes the idea that knowledge is not fixed. High-quality clinical work requires ongoing inquiry about best evidence throughout clinicians’ careers. EBP is not usually linked to efforts to lobby for funding. EBP activity might be professionally advantageous, but it is not an argument for undertaking it. Although evidence about health disparities may lead to innovative strategies to combat health disparities, EBP per se does not promote their elimination.

B) the use of evidence by individual clinicians in their practice.

C) the adaptation of innovations for diverse cultural groups.

D) system-wide efforts to apply new evidence in practice settings.

Ans: D Feedback: The term knowledge translation (KT), a term coined by the Canadian Institutes of Health Research, generally refers to institutional, system-wide projects to make changes based on emerging evidence. KT is not specifically aimed at international efforts to translate evidence into diverse languages or at adapting innovations for diverse cultural groups. EBP, and not KT, is focused on the use of evidence by individual clinicians.

Clinical practice guidelines give specific recommendations for evidence-based decision making, often based on experts’ analysis of systematic reviews. Their intent is to influence what clinicians do in specific situations, not in the general use of EBP. Guidelines are often context-specific, and so different guidelines may be used in different countries or for different populations. The purpose of the guidelines is to guide clinicians, not to guide researchers regarding what areas are in need of further study.

Which of the following can be used to critically appraise clinical practice guidelines?

A) The PRECIS-2 instrument B) The Iowa model C) The AGREE II instrument D) GRADE Ans: C Feedback: Evidence-based clinical practice guidelines distill a body of evidence into a usable form. Several appraisal instruments are available to evaluate clinical practice guidelines, but one with broad support is the Appraisal of Guidelines Research and Evaluation (AGREE II) Instrument. The Iowa model is used as a framework for an evidence-based project. The PRECIS-2 instrument is used to assess the degree to which a trial design is pragmatic or explanatory. GRADE is used to evaluate degree of confidence in the results of systematic reviews, and these evaluations are sometimes taken into account in developing clinical practice guidelines.

9. Which model was explicitly developed with the idea that individual nurses could engage in research utilization?

A) Iowa Model of EBP B) Johns Hopkins Nursing EBP Model C) Cochrane Model D) Stetler Model Ans: D Feedback: Some models focus on the use of research from the perspective of individual clinicians such as the Stetler Model, one of the oldest models that originated as a research utilization (RU) model. Most models, however, focus on institutional or team-based EBP efforts, such as the John Hopkins Nursing EBP Model and the Iowa Model of EBP.

Several models of EBP, including the Iowa Model, distinguish problem-focused and knowledge-focused triggers. Which of the following is a problem-focused trigger?

A) A paper published about a patient fall intervention in a nursing journal B) A new clinical guideline on strategies to reduce patient falls C) An observed increase in patient falls among patients on a neurological unit D) A journal club discussion of a paper on patient falls Ans: C Feedback: Several models of EBP, such as the Iowa Model, have distinguished two types of stimulus (“triggers”) for an EBP endeavor: (1) problem-focused triggers—the identification of a clinical practice problem in need of solution, or (2) knowledgefocused triggers—findings discovered in the research literature. The observance of an increase in patient falls in a neurologic unit could be the problem “trigger” for an EBP project on that unit. All other alternatives would be knowledge-focused triggers, coming from outside the organization.

A) A report in Journal of Advanced Nursing regarding predictors of pressure injuries among hospitalized older adults B) Increases in the readmission rate of heart failure patients C) Poor patient satisfaction survey results D) Increase in medication errors Ans: A Feedback: Several models of EBP have distinguished two types “triggers” for an EBP endeavor: (1) problem-focused triggers—the identification of a clinical practice problem in need of solution, or (2) knowledge-focused triggers—information from the research literature. A report in a nursing journal regarding factors that affect pressure injuries in hospitalized older adults is an example of a knowledge-focused trigger.

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Feedback: Individual nurses can put research into practice using five basic steps, in this order: (1) asking a clinical question for which research evidence is relevant, (2) searching for and acquiring relevant research evidence, (3) appraising and synthesizing the evidence, (4) integrating evidence with other factors and applying it to clinical practice, and (5) assessing effectiveness.

Format: Multiple Choice Chapter: 18 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Understand Difficulty: Moderate Integrated Process: Nursing Process Objective: 04 Page and Header: 315, Major Steps in Evidence-Based Practice 13. Which of the following is a question that would be asked in appraising research evidence in an individual EBP effort?

A) What are the P, I, C, and O components?

B) How valid and unbiased is the evidence?

C) With what other information should I integrate the evidence?

D) Is a relevant systematic review available?

Ans: B Feedback: In appraising the quality of research evidence, which is the third step in many EBP endeavors, a key question is, “To what extent is the evidence valid? How serious is the risk of biases?” The first step is asking well-worded questions, guided by the PICO question format. The second step is locating and acquiring evidence, which might involve asking whether a relevant systematic review is available. The fourth step is to apply the evidence in making evidence-based decisions or providing evidence-based advice.

A) the precision of evidence estimates.

B) the quality and rigor of the evidence.

C) the magnitude of effects of an intervention.

D) the consistency of the evidence.

Ans: C Feedback: Clinicians assessing relevant evidence in an EBP effort need to understand not only whether the evidence is valid (the quality of the evidence) but also how powerful any effects are—that is, their magnitude. Indexes such as effect size indexes quantify the magnitude of effects of an intervention on outcomes. Such indexes do not provide information about precision or consistency.

Which statement about practice-based evidence is true?

A) Practice-based evidence is an alternative name for evidence-based practice.

B) Practice-based evidence is the kind of evidence most often used in evidencebased practice.

C) Practice-based evidence is evidence developed in real-world contexts, responsive to the needs of clients with varying health challenges.

D) Intervention studies using a randomized design do not yield practice-based evidence.

Ans: C Feedback: Practice-based evidence—which is not an alternative name for evidence-based practice (EBP)—is evidence that has been developed in real-world settings with the aim of being responsive to the needs and circumstances of specific patients. EBP has not traditionally relied on practice-based evidence. Intervention studies using a randomized design can be designed to yield evidence that is more practice-based than has traditionally been the case.

Traditionally, evidence-based practice (EBP) has relied on evidence about: A) patients’ contexts.

B) populations.

C) subgroups of patients.

D) individual patients.

Ans: B Feedback: Traditionally, EBP has been based on evidence about populations of people, not about individual clients, subgroups of clients, or client contexts. EBP relies heavily on evidence from randomized controlled trials about the “average” effects of an intervention on a population of people—the population implied by the eligibility criteria for the trial.

Which of the following statements is true?

A) Randomized controlled trials yield information about average treatment effects for a specified population.

B) Heterogeneity of treatment effects (HTE) is synonymous with average treatment effects.

C) Average treatment effects are avoided in traditional models of evidence-based practice.

D) Individual patients can always benefit from knowledge of average treatment effects from a rigorous randomized trial.

Ans: A Feedback: Page 10

Test Bank for Essentials of Nursing Research, Appraising Evidence for Nursing Practice

Findings from randomized controlled trials (RCTs) are in the form of treatment effects for “average” clients in a specified population. Average treatment effects are usually the evidence used as the basis for EBP. Heterogeneity of treatment effects results when “average” effects do not capture the full range of effects of an intervention. No matter how rigorous the trial, individual patients may not benefit from knowledge of “average” treatment effects because they may not be an “average” member of the specified population.

In a randomized controlled trial of a stress-reducing intervention for family caregivers, the mean effect was an improvement of 3 points on a depression scale.

Some participants improved by 6 or more points and others deteriorated by 3 or more points. This situation reflects: A) universal effects.

B) average treatment effects.

C) subgroup effects.

D) heterogeneity of treatment effects.

Ans: D Feedback: In this situation, the average treatment effect of a 3-point improvement for the population masked considerable diversity in effects, which is referred to as heterogeneity of treatment effects (HTE).

Which of the following is often a constraint on generalizability in traditional (explanatory) randomized controlled trials (RCTs)?

A) Sample sizes in RCTs are usually too small to safely generalize.

B) High rates of participation in the RCT are atypical of what occurs in clinical settings.

C) RCTs are often undertaken in atypical, tightly controlled settings.

D) The follow-up period in the RCTs is too long.

Ans: C Feedback: Traditional explanatory RCTs impose tight controls over many aspects of RCTs— they are often undertaken in tightly controlled and resource-rich settings with highly skilled health care staff that are not “typical.” RCTs typically have shorter follow-up periods than is offered in clinical care, and rates of participation tend to be low. Rigorous RCTs are adequately powered (have a sufficiently large sample size); sample size per se seldom factors into the generalizability of RCT results.

A) Eligibility criteria for RCTs often exclude patients with comorbidities.

B) RCTs are held in such high esteem that rates of participation are typically high.

C) Clinical patients are generally very similar to ones included in traditional RCTs. D) RCTs often select as participants older patients, who might especially benefit from innovative treatments.

Ans: A Feedback: Trialists typically exclude clients with potentially confounding characteristics, such as comorbidities and older age. As a result, study participants may be very different from those in average clinical caseloads. Rates of participation in RCTs tend to be low.

C) Which stakeholders should be involved? When should an intervention be initiated? Who will conduct the research?

D) Which outcomes should be assessed? What design should be used? Who should study participants be?

Ans: A

Feedback: The evolving comparative effectiveness research (CER) model calls for innovations that address three fundamental questions: What works? For whom? and In whose hands? These questions focus squarely on the issue of the applicability of research evidence to individuals, groups of individuals, and to local contexts. All of the other questions are likely to be addressed during the design of a CER study, but they are not fundamental questions about its goals.

Comparative effectiveness research (CER) gives special weight to which type of outcomes?

A) Nursing sensitive outcomes B) Short-term outcomes C) Patient-reported outcomes D) Administrative outcomes Ans: C Feedback: CER prioritizes outcomes that are important to patients and gives weight to patientreported outcomes (e.g., pain, anxiety). CER is interested in long-term (not shortterm) outcomes of health care interventions. CER projects may involve nursingsensitive outcomes (as well as administrative outcomes such as efficiency), but these are not outcomes that are specifically prioritized.

Concern about the disproportionate focus on internal validity in traditional randomized controlled trial designs has led to interest in designs called:

A) efficacy trials.

B) superiority trials.

C) explanatory trials.

D) pragmatic clinical trials.

Ans: D Feedback: Concerns about the applicability and generalizability of evidence from traditional (explanatory) trials has led to interest in pragmatic clinical trials (PCTs), which have features designed to enhance external validity. Traditional explanatory trials are usually superiority trials (the hypothesis is that an intervention is better than a comparator), and the term “efficacy trial” is often used for “Phase III” trials that focus on internal validity using traditional designs.

Which statement about the PRECIS-2 tool is true?

A) The PRECIS-2 tool is used to critically appraise pragmatic clinical trials.

B) The PRECIS-2 tool encompasses three domains.

C) The lower the score on PRECIS-2, the more pragmatic the trial design is.

D) One of the domains that is scored on the PRECIS-2 tool is participant eligibility.

Ans: D Feedback: The PRECIS-2 tool scores from 1 to 5 on the nine domains in the instrument. One domain is for participant eligibility—i.e., how similar study participants are to clients in usual care. Higher (not lower) scores on PRECIS-2 indicate a more pragmatic design. The instrument is not used to critically appraise pragmatic clinical trials.

28. Which research design has been found to be especially useful for pragmatic clinical trials?

A) A cluster randomized design B) A time series design C) A crossover design D) A case-control design Ans: A Feedback: One of the most widely used designs in pragmatic clinical trials is cluster randomized designs that involves randomization of groups of participants (e.g., hospital units) rather than individuals. Such a design protects against contamination of treatments. A crossover design is not especially “pragmatic” and the other two designs are either quasi-experimental (time series) or observational (case-control) that expose them to threats to internal validity and are less useful in pragmatic trials than randomized designs.

Researchers conducting a randomized controlled trial can take several steps with regard to their sampling plan to enhance patient-centered evidence. One of these steps is to: A) exclude patients who have characteristics that could confound the results.

B) make efforts to ensure that research samples reflect the full range of people who could benefit from (or be harmed by) the intervention.

C) sample patients from a single site so that confounding contextual factors will be controlled.

D) make efforts to sample in a manner that avoids heterogeneity of effects.

Ans: B Feedback: For developing practice-based evidence, it is important to sample the full range of people who could benefit from (or be harmed by) the intervention—including people with comorbidities who are often excluded. The other options—excluding clients with potentially confounding characteristics, sampling from a single site, and taking steps to avoid heterogeneity of effects—would undermine practice-based evidence.

Format: Multiple Choice Chapter: 18 Client Needs: Safe and Effective Care Environment: Management of Care Cognitive Level: Apply Difficulty: Moderate Integrated Process: Nursing Process Objective: 07 Page and Header: 322, Subgroup Analyses 30. Epidemiologist Alvan Feinstein described the challenges of subgroup analysis as a “clinicostatistical tragedy.” The challenge to which he was referring was the high risk of: A) making both Type I and Type II errors.

B) focusing on the wrong subgroups.

C) using an inappropriate statistical analysis.

D) having low replicability across studies.

Ans: A Feedback: Feinstein recognized that subgroup analyses are fraught with a high risk of both Type II errors (because of small sample sizes) as well as a high risk of Type I errors (because often too many subgroup analyses are undertaken). It is true that statistical analyses are often performed incorrectly, but this is not the statistical issue to which Feinstein was referring. There is not necessarily a high risk of low replicability (true subgroup effects are replicable) nor a high risk of focusing on the wrong subgroups.

Experts have provided considerable advice about subgroup analysis. Which statement about the appropriate conduct of subgroup analyses is true?

A) For the sake of efficiency, it is prudent to test subgroup treatment effects for 5 to 10 subgroups.

B) If power for the analysis of overall treatment effects is 80%, then the power for each subgroup analysis would also be 80%.

C) Subgroup analyses should be undertaken based on well-grounded hypotheses specified in advance.

D) The subgroups in a subgroup analysis should be defined on the basis of variables measured at follow-up.

Ans: C Feedback: Subgroup analyses should be a hypothesis-testing effort based on hypotheses articulated in advance. Statistical experts advise that only one or two primary subgroup analyses should be conducted. If the power for the overall study is 80%, power for the subgroup analyses would be lower because the sample size for subgroups is necessarily lower than that for the entire sample. Subgroup analyses should be based on variables defined at baseline, not at follow-up.
