Chapter 01: The Patient Interview Des Jardins: Clinical Manifestations and Assessment of Respiratory Disease, 8th Edition MULTIPLE CHOICE 1. The respiratory therapist is conducting a patient interview. The main purpose of this interview

is to: a. review data with the patient. b. gather subjective data from the patient. c. gather objective data from the patient. d. fill out the history form or checklist.

ANS: B

During the interview, the patient provides his or her opinion (subjective data) on the situation. The history should be done before the interview. Although data can be reviewed, that is not the primary purpose of the interview.

REF: p. 2 2. For there to be a successful interview, the respiratory therapist must: a. provide leading questions to guide the patient. b. be an active listener. c. reassure the patient. d. use medical terminology to show knowledge of the subject matter.

ANS: B

The personal qualities that a respiratory therapist must have to conduct a successful interview include being an active listener, having a genuine concern for the patient, and having empathy.

Leading questions must be avoided. Reassurance may provide a false sense of comfort to the patient. Medical jargon can sound exclusionary and paternalistic to a patient.

REF: p. 2 3. Which of the following would NOT be found on a history form? a. Age b. Chief complaint c. Present health d. Family history e. Health insurance provider ANS: E

Age, chief complaint, present health, and family history are typically found on a health history form because each can impact the patient’s health. Health insurance provider information, while needed for billing purposes, would not be found on the history form.

REF: pp. 1- 2 4. The physical setting for the interview should provide for all of the following EXCEPT: a. minimize or prevent interruptions.

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins b. ensure privacy during discussions. c. interviewer is the same sex as the patient to prevent bias. d. be comfortable for the patient and interviewer.

ANS: C

An interviewer of either gender, who acts professionally, should be able to interview a patient of either gender. The other listed options are important to have a successful interview.

REF: p. 2 5. The respiratory therapist is conducting a patient interview. The therapist chooses to use

open- ended questions. Open-ended questions allow the therapist to do all of the following EXCEPT: a. gather information when a patient introduces a new topic. b. introduce a new subject area. c. begin the interview process. d. gather specific information.

ANS: D

An open-ended question should be used to start the interview, introduce a new section of questions, and gather more information from a patient’s topic. Closed or direct questions are used to gather specific information.

REF: p. 3 6. The direct question interview format is used to:

1. speed up the interview.

2. let the patient fully explain his or her situation.

3. help the respiratory therapist show empathy.

4. gather specific information. a. 1, 4 b. 2, 3 c. 3, 4 d. 1, 2, 3, 4 ANS: A

Direct or closed questions are best to gather specific information and speed up the interview. Open-ended questions are best suited to let the patient fully explain his or her situation and possibly help the respiratory therapist show empathy.

REF: pp. 3-4 7. During the interview the patient states, “Every time I climb the stairs I have to stop to catch

my breath.” Hearing this, the respiratory therapist replies, “So, it sounds like you get short of breath climbing stairs.” This interviewing technique is called: a. clarification. b. modeling. c. empathy. d. reflection.

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins ANS: D

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

With reflection, part of the patient’s statement is repeated. This lets the patient know that what he/she said was heard. It also encourages the patient to elaborate on the topic. Clarification, modeling, and empathy are other communication techniques.

REF: pp. 3-5 8. The respiratory therapist may choose to use the patient interview technique of silence in which

of the following situations?

To prompt the patient to ask a question After a direct question After an open-ended question To allow the patient to review his or her history

a. b. c. d.

ANS: C

After a patient has answered an open-ended question, the respiratory therapist should pause (use silence) before asking the next question. This pause allows the patient to add something else before moving on. The patient may also choose to ask a question.

REF: p. 4 9. To have the most productive interviewing session, the respiratory therapist must avoid all of

the following types of verbal messages EXCEPT: confrontation. giving advice. using avoidance language. distancing.

a. b. c. d.

ANS: A

With confrontation, the respiratory therapist focuses the patient’s attention on an action, feeling, or statement made by the patient. This may prompt a further discussion. The respiratory therapist should avoid giving advice, using avoidance language, and using distancing language.

REF: pp. 5-6 10. When closing the interview, the respiratory therapist should do which of the following?

1. Recheck the patient’s vital signs.

2. Thank the patient.

3. Ask if the patient has any questions.

4. Close the door behind himself or herself for patient privacy. a. 2 b. 2, 3 c. 1, 3, 4 d. 1, 2, 3, 4 ANS: B

To end the interview on a positive note, the respiratory therapist should thank the patient and ask if the patient has any questions. If there is no need for the vital signs to be checked, they should not be. The door may be left open or closed, depending on the situation.

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins 11. The respiratory therapist should be aware of a patient’s culture and religious beliefs for

which of the following reasons? a. To be able to engage in a meaningful conversation b. To change any misguided notions the patient has that may impact his or her health c. To explain to the patient how these beliefs will lead to discrimination and

stereotyping d. To better understand how the patient’s beliefs may impact how the patient thinks

and behaves ANS: D

Culture and religious beliefs may have a profound effect on how patients think and behave, and this may impact their health or health-care decisions. The role of the respiratory therapist is not to change the patient’s beliefs, engage in sensitive conversations, or discuss discrimination. Rather, the respiratory therapist needs to understand how these beliefs may impact the patient’s health-care decisions.

REF: pp. 2-3 12. Which of the following are the most important components of a successful interview? a. Communication and understanding b. Authority and the use of medical terminology c. Providing assurance and giving advice d. Asking leading questions and anticipating patient responses to questions ANS: A

Communication and understanding are the basis for a good patient interview. Authority, the use of medical jargon, providing assurance, giving advice, asking leading questions, and anticipating are all types of nonproductive communication forms and create barriers to patient communication.

REF: p. 2 13. The respiratory therapist is conducting a patient interview and recording responses in the

patient’s electronic health record. The respiratory therapist should take which of the following into account regarding the use of the computer to record responses? a. The therapist’s attention may be shifted from the patient to the computer. b. The patient will feel more important than if the information is recorded on paper. c. The therapist will be less likely to make spelling errors if using a spell-check program. d. The environment will be more professional and the patient will be more likely to open up if the interview is conducted with paper.

ANS: A

The therapist’s use of the computer can be threatening and may, in some cases, be a potential hazard to good patient communication. The patient can be intimidated to the point of “shutting down.” In addition, the therapist who has to shift focus from the patient to the computer can miss important verbal and nonverbal messages.

Chapter 02. The Physical Examination Des Jardins: Clinical Manifestations and Assessment of Respiratory Disease, 8th Edition MULTIPLE CHOICE 1. When would induced hypothermia be indicated? a. During brain surgery b. During bowel surgery c. To break a fever d. To treat carbon monoxide poisoning ANS: A

There are times during brain or cardiac surgery that hypothermia is induced to lower the patient’s metabolism so that less oxygen is needed by the body. If a patient has a high fever, measures are taken to lower it but not to the point of hypothermia. Carbon monoxide poisoning is not treated by hypothermia.

REF: pp. 11-12 2. A 50-year-old patient has a heart rate by palpation of 120 bpm. How should this

be interpreted?

Within the normal range for an adult An error since a stethoscope was not used Bradycardia Tachycardia

a. b. c. d.

ANS: D

In an adult, a heart rate of greater than 100/minute is considered to be tachycardia. A heart rate of less than 60/minute in an adult is considered to be bradycardia. Palpation and auscultation are both acceptable to check heart rate.

REF: p. 14 3. Tachypnea may be the result of:

1. hypoxemia.

2. hypothermia.

3. fever.

4. sedation. a. 2, 4 b. 1, 3 c. 2, 3, 4 d. 1, 2, 3, 4 ANS: B

Tachypnea may be the result of hypoxemia, fever, and other causes. Hypothermia and sedation will usually result in bradycardia.

REF: p. 15

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins 4. A 50-year-old patient would be said to have hypotension when her: a. blood pressure is 130/90 mm Hg. b. blood pressure is 85/55 mm Hg. c. heart rate is 55 bpm. d. pulse pressure is 40 mm Hg. ANS: B

In an adult, hypotension is defined as a blood pressure of 90/60 mm Hg. A heart rate of 55 bpm would be bradycardia. Pulse pressure is normally about 40 mm Hg. REF: p. 17 5. A dull percussion note would be heard in all of the following situations EXCEPT: a. atelectasis. b. pleural thickening. c. chronic obstructive pulmonary disease (COPD). d. consolidation.

ANS: C

Because of hyperinflation, a patient with COPD would have a hyperresonant percussion note.

All of the other listed options would result in a dull percussion note.

REF: p. 29 6. Coarse crackles are associated with:

1. inspiration typically.

2. air passing through an airway intermittently occluded by mucus.

3. bronchial asthma.

4. expiration typically. a. 2, 4 b. 3, 4 2. The Physical Examination 3. The Pathophysiologic Basis for Common Clinical Manifestations c. 2, 3, 4 d. 1, 2, 3 ANS: A

Coarse crackles are associated with air passing through an airway intermittently occluded by mucus; they are more typically heard during inspiration, not expiration. Wheezes are an expiratory sound associated with bronchial asthma.

REF: p. 30 7. While assessing an unconscious patient, the respiratory therapist observes that the

patient’s breathing becomes progressively faster and deeper and then progressively becomes slower and shallower. After that, there is a period of apnea before the cycle begins again. This breathing pattern would be identified as: a. Cheyne-Stokes. b. tachypnea. c. Kussmaul.

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins d. hyperventilation.

ANS: A

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

The abnormal breathing pattern called Cheyne-Stokes is identified by progressively faster and deeper breathing that then progressively becomes slower and more shallow. After that there is a period of apnea before the cycle begins again. Tachypnea is rapid breathing.

Kussmaul breathing is consistently fast and deep breathing. Hyperventilation is confirmed by a low carbon dioxide level.

REF: p. 17 8. Benefits of pursed-lip breathing include that it:

1. stabilizes airways.

2. offsets air trapping on exhalation.

3. generates a better gas mixing breathing pattern.

4. slows the respiratory rate. a. 1 b. 2, 3 c. 1, 2, 3 d. 1, 2, 3, 4 ANS: D

All of the listed options are benefits of pursed-lip breathing in a patient with an airway obstruction problem such as asthma or COPD. REF: p. 29 9. A patient comes into the emergency department with a complaint of centrally located, constant

chest pain. What is his most likely problem? a. Pleurisy b. Myocardial ischemia c. Pneumothorax d. Fractured rib ANS: B

Often a patient with myocardial ischemia will complain of centrally located, constant chest pain. The pain may also radiate down an arm or up the neck.

REF: p. 37 10. A patient with bronchiectasis has a productive cough. Which of the following should the

respiratory therapist be evaluating about the patient’s sputum?

1. Color 2. Odor 3. Amount 4. Consistency a. 3 b. 3, 4 c. 1, 2 d. 1, 2, 3, 4 ANS: D

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

The respiratory therapist should evaluate a patient’s sputum for color, odor, amount, consistency, and any other significant factors. This could include time of greater or smaller amounts or a change in consistency after inhaling a mucolytic medication.

REF: p. 42 11. The respiratory therapist is monitoring the blood pressure of a patient in the

emergency department and notes that the blood pressure is 15 mm Hg less on inspiration than on expiration. Which of the following would most likely result in this finding? a. The patient is hypovolemic. b. The patient has a pulmonary embolism. c. The patient is having a myocardial infarction. d. The patient is having a severe exacerbation of asthma.

ANS: D

A change in blood pressure that is more than 10 mm Hg lower on inspiration than on expiration is known as pulsus paradoxus. This exaggerated waxing and waning of arterial blood pressure can be detected with a sphygmomanometer or, in severe cases, by palpating the pulse at the wrist or neck. Commonly associated with severe asthmatic episodes, pulsus paradoxus is believed to be caused by the major intrapleural pressure swings that occur during inspiration and expiration.

REF: p. 55 12. The respiratory therapist is examining a patient in the medical ward and notes that the

trachea is deviated to the left. All of the following may be causing the tracheal deviation to the left EXCEPT: a. a right-sided tension pneumothorax. b. a right-sided pleural effusion. c. a tumor mass on the right. d. atelectasis of the right upper lobe.

ANS: D

A number of abnormal pulmonary conditions can cause the trachea to deviate from its normal position. For example, a tension pneumothorax, pleural effusion, or tumor mass may push the trachea to the unaffected side (in this case to the left), whereas atelectasis pulls the trachea to the affected side (in this case to the right).

REF: pp. 52-53 13. The respiratory therapist is performing palpation on a patient recently admitted to the

medical ward. The therapist notes decreased tactile fremitus over the right lung. Which of the following could MOST likely be the cause for this physical exam finding? a. Right-sided atelectasis b. Right-sided pneumothorax c. Right-sided pleural effusion d. Right-sided pleural tumor ANS: A

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Tactile fremitus decreases when anything obstructs the transmission of vibration. Such conditions include tumors or thickening of the pleural cavity, pleural effusion, and pneumothorax. Tactile fremitus increases in patients with atelectasis.

Chapter 04. Pulmonary Function Testing Des Jardins: Clinical Manifestations and Assessment of Respiratory Disease, 8th Edition MULTIPLE CHOICE 1. Pulmonary function studies are done for all of the following measurements EXCEPT: a. the patient’s carbon monoxide level. b. lung volumes and capacities. c. pulmonary diffusion capacity. d. forced expiratory flow rates.

ANS: A

A blood sample must be analyzed by a cooximeter to determine a patient’s carbon monoxide level. All of the other listed options can be measured on a pulmonary function test.

REF: p. 45 2. In response to a restrictive lung disorder, which of the following is typically found?

1. Decreased lung compliance 2. Increased ventilatory rate 3. Decreased tidal volume 4. Decreased lung rigidity a. 1 b. 2, 3 c. 2, 3, 4 d. 1, 2, 3 ANS: D

With a restrictive lung disorder, there will be increased lung rigidity. This causes decreased lung compliance. As a result, the patient breathes faster and with a smaller tidal volume.

REF: p. 45 3. A special indirect measurement procedure must be done to find which of the following? a. Inspiratory reserve volume b. Residual volume c. Expiratory reserve volume d. Inspiratory capacity ANS: B

Because the residual volume cannot be measured by spirometry, special procedures and equipment must be used to indirectly measure it. The other listed options can be directly measured by spirometry.

REF: p. 45 4. Which of the following forced vital capacity test times should be interpreted as normal? a. Less than 4 seconds b. 4 to 6 seconds

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins c. 6 to 8 seconds d. 8 to 10 seconds ANS: B

A normal adult will exhale a forced vital capacity (FVC) within 4 to 6 seconds. Patients with restrictive lung diseases may blow out the FVC in less than 4 seconds. Patients with obstructive lung diseases will need more than 6 seconds to blow out the FVC. REF: p. 48 5. Overall characteristics of pulmonary function testing results on a patient with obstructive

lung disease include that the FEV1: is reduced and FEV1% is normal. and FEV1% are both increased. and FEV1% are both reduced. is increased and FEV1% is decreased.

a. b. c. d.

ANS: C

Because of airway narrowing problems, a patient with obstructive lung disease will have a reduced FEV1 volume and FEV1% flow. A patient with restrictive lung problems may have FEV1 reduced and FEV1% normal. The other combinations are not seen.

REF: p. 48 6. The FEF25%-75% is used to evaluate: a. flow in large airways. b. restrictive lung disease. c. maximum breathing effort. d. flow in medium-size to small airways.

ANS: D

Expiratory flow in medium-size to small airways is assessed by the FEF25%-75% test. Other tests would be needed to assess the other listed options.

REF: p. 49 7. All of the following are true of the peak expiratory flow rate test EXCEPT it: a. is effort dependent. b. is taken from the FVC test results. c. is taken from the MVV test results. d. assesses large upper airways.

ANS: C

The maximum voluntary ventilation (MVV) test is used to measure the maximum amount of air that can be breathed in a minute. The peak flow requires maximum effort from the patient, is taken from the FVC test, and assesses flow through the large upper airways.

REF: p. 51 8. A patient has restrictive lung disease. In response to this, which of the following are typically

found?

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

1. Decreased lung compliance

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

2. Increased ventilatory rate 3. Increased tidal volume 4. Decreased ventilatory rate a. 3, 4 b. 2, 3 c. 1, 2 d. 1, 3, 4 ANS: C

Restrictive lung disorders result in an increase in lung rigidity, which in turn decreases lung compliance. When lung compliance decreases, the ventilatory rate increases and the tidal volume decreases.

REF: p. 45 9. The pulmonary diffusion capacity of the carbon monoxide test is used to: a. assess the patient’s blood carbon monoxide level. b. remove carbon monoxide from the patient’s blood. c. measure the residual volume. d. assess the alveolar-capillary membrane.

ANS: D

Alveolar-capillary membrane function is measured by the pulmonary diffusion capacity of the carbon monoxide test. A very small amount of carbon monoxide (CO) is inhaled by the patient to perform the test. But the CO level is not measured in the blood, and CO is not removed from the blood.

REF: p. 52 10. Total lung capacity is composed of all of the following EXCEPT: a. IRV. b. IC. c. ERV. d. RV. ANS: A

Total lung capacity (TLC) can be calculated by adding IC, ERV, and RV. Also see Figure 3-1 for other ways to calculate the TLC. REF: p. 46 11. A respiratory therapist has just performed a pulmonary function study and notes that the

results show obstructive lung disease with a decreased DLCO value. Which of the following is the best interpretation of these results? a. The patient has pulmonary fibrosis. b. The patient has asthma. c. The patient has cystic fibrosis. d. The patient has emphysema. e. The patient has chronic bronchitis.

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins ANS: D

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

A decreased DLCO is a hallmark clinical manifestation in emphysema because of the destruction of the alveolar pulmonary capillaries and decreased surface area for gas diffusion associated with the disease. The DLCO is usually normal in all other obstructive lung disorders. Pulmonary fibrosis is a restrictive disease, not an obstructive disease.

REF: p. 55 12. The respiratory therapist is called to the neurologic care unit to assess the muscle strength of

a patient diagnosed with myasthenia gravis. Which of the following tests should the therapist recommend to assess respiratory muscle strength? a. Maximum inspiratory pressure (MIP) b. Maximum inspiratory flow rate (MIFR) c. Maximum expiratory flow rate (MEFR) d. Vital capacity (VC) ANS: A

The most commonly used tests to evaluate the patient’s respiratory muscle strength at the bedside are maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), forced vital capacity (FVC), and maximum voluntary ventilation (MVV).

REF: p. 52 13. The respiratory therapist is performing a pulmonary function study on a patient who has

periodic symptoms of asthma. The pulmonary function results are within normal limits. What further testing can the therapist recommend to aid in either confirming or negating the possible diagnosis? a. Inhaled methacholine challenge testing b. Body plethysmography c. Inhaled digitalis d. Warm, humid air challenge ANS: A

Because some patients have clinical manifestations associated with asthma but normal lung function, measurements of airway responsiveness to inhaled methacholine or a cold air challenge may be useful in confirming a diagnosis of asthma. A warm, humid air challenge would not be effective in producing results consistent with airway reactiveness. Body plethysmography is used to determine functional residual capacity. This would not be helpful in establishing a diagnosis of asthma.

The normal PaCO2 range is 35 to 45 mm Hg; below this is hypocapnia, and above this is hypercapnia.

REF: p. 58 2. Which of the following would be a normal person’s venous oxygen pressure (PaO2)? a. 35 to 45 mm Hg b. 45 to 80 mm Hg c. 80 to 100 mm Hg d. 100 to 120 mm Hg ANS: A

A normal person’s PaO2 is 35 to 45 mm Hg. Higher values could only be achieved by giving the person supplemental oxygen.

REF: p. 58 3. All of the following will be seen in the arterial blood gas values of a patient with acute

ventilatory failure EXCEPT a(n): acidic pH. near-normal bicarbonate level. alkaline pH. high carbon dioxide level.

a. b. c. d.

ANS: C

An alkaline pH could be caused by hyperventilation. Ventilatory failure with a high CO2 level would cause an acidotic pH, with a near-normal bicarbonate level.

REF: p. 62 4. What causes stimulation of the peripheral chemoreceptors to increase the ventilatory rate? a. Pain or anxiety b. PaCO2 of about 40 mm Hg c. PaO2 of about 60 mm Hg d. Venous pH of 7.30 to 7.40 ANS: C

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

A lower than normal PaO2 of about 60 mm Hg or less will stimulate the peripheral chemoreceptors. These chemoreceptors will not be stimulated by pain or anxiety, normal PaCO2, or normal venous pH. REF: p. 62 5. A patient has had chronic ventilatory failure for several years. What is the primary factor

that determines her breathing pattern?

Muscle efficiency Ventilatory efficiency Heart function Work efficiency

a. b. c. d.

ANS: D

It is work efficiency (calories consumed) rather than ventilatory efficiency that determines a person’s breathing pattern. Muscle efficiency and heart function do not affect breathing pattern.

REF: p. 63 6. An anion gap of 15 would indicate: a. metabolic acidosis. b. respiratory alkalosis. c. respiratory acidosis. d. metabolic alkalosis.

ANS: A

An anion gap of 15 or higher would indicate a metabolic acidosis. The normal gap is 9 to 14 mEq/L. REF: p. 66 7. Common causes of metabolic acidosis include all of the following EXCEPT: a. diabetic ketoacidosis. b. shallow breathing from a sedative overdose. c. lactic acidosis. d. renal (kidney) failure.

ANS: B

Shallow breathing from a sedative overdose would cause a respiratory acidosis. All of the other options would cause a metabolic acidosis.

REF: p. 66 8. Which of the following would be found in a stable patient with long-standing obstructive lung

disease? a. Low bicarbonate level and low carbon dioxide level b. Low bicarbonate level and high carbon dioxide level c. High bicarbonate level and low carbon dioxide level d. High bicarbonate level and high carbon dioxide level Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins ANS: D

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

A high bicarbonate level and high carbon dioxide level are found in a stable patient with longstanding obstructive lung disease. The other options are associated with other acid-base disorders.

REF: p. 66 9. Common causes of metabolic alkalosis include:

1. diuretic therapy.

2. vomiting.

3. excessive sodium bicarbonate administration.

4. gastric suctioning. a. 1, 3 b. 2, 4 c. 2, 3, 4 d. 1, 2, 3, 4 ANS: D

All of the listed options can cause metabolic alkalosis.

REF: p. 66 10. The most common cause of acute alveolar hyperventilation is: a. hypoxemia. b. metabolic alkalosis. c. tachycardia. d. supplemental oxygen administration.

ANS: A

The most common cause of acute alveolar hyperventilation is hypoxemia. The decreased PaO2 seen during acute alveolar hyperventilation usually develops from a decreased ventilationperfusion ratio, capillary shunting, or venous admixture associated with a pulmonary disorder. The PaO2 continues to drop as the pathologic effects of the disease intensify.

Eventually the PaO2 may decline to a point low enough (a PaO2 of about 60 mm Hg) to significantly stimulate the peripheral chemoreceptors, which in turn causes the ventilatory rate to increase. The increased ventilatory response in turn causes the PaCO2 to decrease and the pH to increase.

REF: p. 62 11. Mechanical ventilation is indicated for which of the following ABG results? a. pH 7.56; PaCO2 27; HCO3 23; PaO2 63 b. pH 7.23; PaCO2 63; HCO3 26; PaO2 52 c. pH 7.36; PaCO2 79; HCO3 43; PaO2 61 d. pH 7.52; PaCO2 51; HCO3 40; PaO2 46 ANS: B

When an increased PaCO2 is accompanied by acidemia (decreased pH), acute ventilatory failure, or respiratory acidosis, is said to exist. Clinically, this is a medical emergency that may require mechanical ventilation.

in the ICU. The results show a pH and PaO2 that seem unreasonably high, while the PaCO2 seems unreasonably low. Which of the following would most likely cause these erroneous results? a. A venous sample was obtained. b. There was excessive heparin in the blood gas syringe. c. The sample was excessively delayed in analysis. d. There was an air bubble in the sample.

ANS: D

An air bubble in the sample would cause an increase in the pH and PaO2 while causing a decrease in PaCO2.

REF: p. 67 13. The respiratory therapist is assessing a patient with end-stage COPD who was admitted to

the medical ward for an exacerbation of COPD due to increasing sputum purulence. The therapist notes the following ABG results in the patient’s electronic medical record: pH 7.52, PaCO2 51; HCO3 40; PaO2 46. Which of the following is the best interpretation of these ABG results? a. Chronic ventilatory failure with hypoxemia b. Acute ventilatory failure with hypoxemia c. Partially compensated metabolic alkalosis with hypoxemia d. Partially compensated respiratory acidosis with hypoxemia e. Acute alveolar hyperventilation superimposed on chronic ventilatory failure ANS: E

An end-stage COPD patient would be expected to have chronic ventilatory failure for baseline ABG results. During an exacerbation, he or she may also experience acute periods of hyperventilation. If able, these patients have the mechanical reserve to increase their alveolar ventilation significantly in an attempt to maintain their baseline PaO2, which has decreased in relation to an acute pulmonary problem, in this case an increase in sputum purulence.

When excessive alveolar ventilation occurs, this action causes the patient’s PaCO2 to decrease from its normally “high baseline” level. As the PaCO2 decreases, the arterial pH increases. As this condition intensifies, the patient’s baseline ABG values can quickly change from chronic ventilatory failure to acute alveolar hyperventilation superimposed on chronic ventilatory failure. If the therapist does not know the past history of the patient with acute alveolar hyperventilation superimposed on chronic ventilatory failure, he or she might initially interpret the ABG values as signifying partially compensated metabolic alkalosis with severe hypoxemia. However, the clinical situation that offsets this interpretation is the presence of marked hypoxemia. A low oxygen level is not normally seen in patients with pure metabolic alkalosis. Thus, whenever the ABG values appear to reflect partially compensated metabolic alkalosis but the condition is accompanied by significant hypoxemia, the respiratory therapist should be alert to the possibility of acute alveolar hyperventilation superimposed on chronic ventilatory failure.

Chapter 06. Assessment of Oxygenation Des Jardins: Clinical Manifestations and Assessment of Respiratory Disease, 8th Edition MULTIPLE CHOICE 1. When a sample of arterial blood is analyzed for the pressure of oxygen (PaO2), the value

comes from the: a. blood plasma. b. leukocytes. c. hemoglobin. d. erythrocytes.

ANS: A

A blood gas analyzer measures the pressure of oxygen and carbon dioxide in the blood plasma. Oxygen is chemically bound to the hemoglobin in the erythrocytes and is measured by an oximeter as the saturation, not as a partial pressure. Leukocytes do not carry oxygen.

REF: p. 70 2. Oxygen consumption:

1. increases with exercise.

2. is the amount of oxygen used by the body.

3. is inversely related to carbon dioxide production.

4. is about 250 mL/min in the resting adult. a. 1, 2 b. 3, 4 c. 2, 4 d. 1, 2, 4 ANS: D

Oxygen consumption is the amount of oxygen used by the body and increases with exercise.

At rest, an adult consumes about 250 mL/min. Oxygen use is not inversely related to carbon dioxide production.

REF: p. 74 3. A patient has been exposed to carbon monoxide during a house fire. An ABG result shows a

normal PaO2. How should the patient’s PaO2 value be interpreted?

The PaO2 is being falsely elevated by the carbon monoxide.

The PaO2 is being falsely decreased by the carbon monoxide.

The PaO2 is accurate.

The PaO2 is a false measurement because the presence of carbon monoxide makes the analyzer unable to determine the PaO2.

a. b. c. d.

ANS: C

The patient’s plasma PaO2 value may be normal or high. This can mislead the respiratory therapist because the patient’s total oxygen value (CaO2) is low. Remember that carbon monoxide will prevent hemoglobin from carrying oxygen.

ANS: B

Peripheral shunting decreases the C(a-v)O2 because less oxygen is extracted by the tissues. All of the other listed options increase oxygen extraction and so will increase the C(a-v)O2.

REF: p. 76 5. A sample of blood has been taken from a patient’s pulmonary artery. What mixed venous

oxygen saturation value (SvO2) would indicate that the patient is normal?

40 mm Hg 95 mm Hg 75% 97%

a. b. c. d.

ANS: C

A normal SvO2 is 75%. Normal PvO2 is 40 mm Hg. Normal arterial blood values for oxygen are SaO2 of 97% and PaO2 of 95 mm Hg. REF: p. 74 6. Polycythemia is:

a. b. c. d.

1. a condition of too many red blood cells.

2. a condition of too few red blood cells.

3. caused by lack of iron in the diet.

4. the body’s response to chronic hypoxemia.

1, 2 2, 3 1, 4 2, 4

ANS: C

The body’s response to chronic hypoxemia is to produce too many red blood cells; this is polycythemia. Lack of iron in the diet could lead to anemia.

REF: pp. 77-78 7. A patient has a chronic respiratory disorder and vasoconstriction of her pulmonary

vascular system. What is the chief control over this vasoconstriction?

Low PAO2 Low PaO2 High PaCO2 High pH

a. b. c. d.

ANS: A Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

A low PAO2 (pressure of alveolar oxygen) is primarily responsible for pulmonary vasoconstriction. Arterial oxygen and carbon dioxide values and pH are not causes.

REF: pp. 77-78 8. An increased cardiac output causes the:

a. b. c. d.

1. C(a-v)O2 to decrease.

2. SvO2 to increase.

3. total O2 delivery to decrease.

4. O2ER to increase.

1 2, 3 3, 4 1, 2

ANS: D

As cardiac output increases, less oxygen is extracted from the blood. Because of this, the C(av)O2 decreases and SvO2 increases. Increased cardiac output would also increase total oxygen delivery and decrease the oxygen extraction ratio.

REF: p. 76 9. A condition that will cause hypoxic hypoxia is: a. cyanosis. b. decreased cardiac output or heart failure. c. hypoventilation from an overdose of a sedative medication. d. carbon monoxide poisoning.

ANS: C

Hypoventilation from any cause will cause hypoxic hypoxia because an inadequate amount of oxygen is breathed in. Cyanide poisoning will cause histotoxic hypoxia because the tissue cells will not be able to metabolize oxygen. Decreased cardiac output or heart failure will cause circulatory hypoxia because the heart will not deliver enough blood and oxygen to the tissues. Carbon monoxide poisoning will cause anemic hypoxia because the hemoglobin cannot carry oxygen.

REF: pp. 77-78 10. A condition that will cause anemic hypoxia is: a. cyanide poisoning. b. decreased cardiac output or heart failure. c. polycythemia. d. carbon monoxide poisoning.

ANS: D

Carbon monoxide poisoning will cause anemic hypoxia because the hemoglobin cannot carry oxygen. Cyanide poisoning will cause histotoxic hypoxia because the tissue cells will not be able to metabolize oxygen. Decreased cardiac output or heart failure will cause circulatory hypoxia because the heart will not deliver enough blood and oxygen to the tissues.

Polycythemia does not cause hypoxia.

of tissue hypoxia. Laboratory results reveal the following: HgB 14.8 grams, CaO2 19.6 vol. %, PaO2 102 mm Hg, a-v difference 9.8 vol. %, PvO2 24 mm Hg. Based on these results, which of the following types of hypoxia does this patient have? a. Hypoxic hypoxia b. Anemic hypoxia c. Circulatory hypoxia d. Histotoxic hypoxia ANS: C

An increase in the a-v difference is due to a decrease in cardiac output (circulatory hypoxia).

The cardiac output and a-v difference are inversely related, and an a-v difference of 9.9 vol. % is evidence of the inadequacy of the cardiac output.

REF: pp. 77-78 12. The respiratory therapist is reviewing a patient’s electronic medical record to try to verify

if the patient has tissue hypoxia. Which of the following laboratory values is MOST likely to correlate with tissue hypoxia? a. Metabolic acidosis b. Thrombocytopenia c. Hypokalemia d. Bilirubinemia ANS: A

When hypoxia exists, alternate anaerobic mechanisms are activated in the tissues that produce dangerous metabolites—such as lactic acid—as waste products. Lactic acid is a nonvolatile acid and causes the pH to decrease, resulting in metabolic acidosis.

REF: p. 77 13. A patient is mildly hypoxemic. Which of the following signs would the respiratory therapist

expect to find in this patient?

An increase in the patient’s breathing rate and heart rate A decrease in systemic blood pressure Cardiac dysrhythmias on an EKG Anemia

a. b. c. d.

ANS: A

Clinically, the presence of mild hypoxemia generally stimulates the oxygen peripheral chemoreceptors to increase the patient’s breathing rate and heart rate; consequently blood pressure may slightly increase, not decrease. Cardiac dysrhythmias would not be expected with mild hypoxemia. Anemia is unrelated to mild hypoxemia.

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Patients with pulmonary edema (hypervolemia) will have an increased pulmonary capillary wedge pressure (PCWP) and decreased cardiac output (CO). The lung damage caused by COPD leads to increased pulmonary vascular resistance (PVR). The PA pressure will be increased with pulmonary edema.

REF: pp. 86-87 11. The respiratory therapist is assessing a patient with sinus tachycardia. Which of the

following would LEAST likely be a cause of the sinus tachycardia? hypoxemia severe anemia hyperthermia massive hemorrhage beta blocker medications

a. b. c. d. e.

ANS: E

Common abnormal causes of sinus tachycardia include hypoxemia, severe anemia, hyperthermia, massive hemorrhage, pain, fear, anxiety, hyperthyroidism, and sympathomimetic or parasympatholytic drug administration. Beta blocker medication may lead to sinus bradycardia, not sinus tachycardia.

REF: pp. 81-82 12. The respiratory therapist is monitoring a patient in the medical ICU and notes multiple

premature ventricular complexes (PVCs) on the cardiac monitor. The respiratory therapist elects to review the patient’s medication administration record (MAR) for medications the patient is receiving to rule out medication toxicity as a cause of the PVCs. Which of the following medications should the therapist evaluate as a possibility of inducing PVCs? a. Theophylline b. Beta blockers c. Vitamin D d. Acetaminophen ANS: A

PVCs may be a sign of theophylline or alpha-stimulate or beta-agonist toxicity. Beta blockers may lead to sinus bradycardia. Vitamin D and acetaminophen would not cause PVCs. REF: pp. 83-84 13. The respiratory therapist is called to a patient’s room as part of the rapid response team

ANS: B

The vast majority of chest radiographs are taken at full inspiration when the breath is held. A patient with obstructive lung disease may also have an expiratory film taken to compare the position of the hemidiaphragms. Panting should not be done because the movement would blur the image on the film.

The respiratory therapist would MOST likely recommend which of the following chest radiographic views to help determine if the patient has a pleural effusion? a. An AP film b. A PA film c. A left lateral film d. A lordotic film e. A lateral decubitus film ANS: E

The lateral decubitus radiograph is useful in the diagnosis of a suspected or known fluid accumulation in the pleural space (i.e., a pleural effusion) that is not easily seen in the PA radiograph. A pleural effusion, which is usually more thinly spread out over the diaphragm in the upright position, collects in the gravity-dependent areas while the patient is in the lateral decubitus position, allowing the fluid to be more readily seen.

embolus. The respiratory therapist would MOST likely recommend which of the following diagnostic procedures to help determine if the patient has a pulmonary embolus? a. CTPA b. Fluoroscopy c. PET scan d. MRI scan e. CT scan ANS: A

Computed tomography pulmonary angiogram (CTPA) (also called a CT pulmonary angiography) with intravenous contrast has largely replaced pulmonary angiography and is fast becoming the first-line test for diagnosing suspected pulmonary embolism. The CTPA is now a preferred choice of imaging in the diagnosis of a pulmonary embolism because the only invasive requirement for the scan is an intravenous line.

REF: pp. 100-101 13. The respiratory therapist is reviewing the electronic medical record of a patient in the

medical ICU. In reading the most recent chest radiograph interpretation, the therapist notes that the cardiothoracic ratio is stated to be less than 1:2 on the PA view. How should the therapist interpret this information? a. This is a normal cardiothoracic ratio. b. This is a decreased cardiothoracic ratio. c. This ratio shows hyperinflation of the lung fields with subsequent air trapping. d. This interpretation should be ignored because it is inaccurate in the PA view.

ANS: A

On the PA projection the ratio of the width of the heart to the thorax (the cardiothoracic ratio) is normally less than 1:2. In other words, normally the width of the heart should be less than 50% of the width of the thorax.

old child with cystic fibrosis?

High-dose ibuprofen High-dose acetaminophen High-dose naproxen High-dose corticosteroids

a. b. c. d.

ANS: A

High-dose ibuprofen is recommended in children and young adolescents with mild CF who have good lung function (an FEV1 >60% predicted) and no contraindications (e.g., gastrointestinal bleeding or renal impairment). Ibuprofen has been shown to reduce bronchial inflammation without hindering bacterial clearance—resulting in the decline of the patient’s FEV1 per year—with no remarkable side effects except painless gastrointestinal bleeding in 1% to 2% of patients. High-dose ibuprofen is thought to work by decreasing neutrophil migration and inflammation in the lungs. The initiation of ibuprofen is not recommended after the age of 13 years.

should be recommended by the respiratory therapist?

Provide supplemental oxygen.

Begin mechanical ventilation.

Have the patient use pursed-lip breathing.

Begin bronchopulmonary hygiene therapy.

a. b. c. d.

ANS: A

Cyanosis indicates hypoxemia. Giving supplemental oxygen will help to correct the hypoxemia and decrease the patient’s work of breathing. Mechanical ventilation is not yet indicated. Pursed-lip breathing may help the breathing of a patient with an obstructive lung problem. Bronchopulmonary hygiene therapy is not indicated because there is no sign of a secretion problem.

REF: p. 299 12. Mask CPAP is used with pulmonary edema patients because it does all of the following

EXCEPT: decrease vascular congestion. reduce work of breathing. it is less expensive than mechanical ventilation. improve lung compliance.

a. b. c. d.

ANS: C

Although CPAP may be less expensive than mechanical ventilation, that is not why it is used.

Mask CPAP is used because it decreases vascular congestion, reduces work of breathing, and improves lung compliance. These things improve oxygenation and may preclude the need for mechanical ventilation.

REF: p. 299 13. A patient with cardiogenic pulmonary edema has had intravascular catheters placed

chest radiograph findings EXCEPT: depressed diaphragms. pleural effusion. cardiomegaly. bilateral “butterfly” pattern fluffy infiltrates.

a. b. c. d.

ANS: A

The position of the diaphragms will not be changed by pulmonary edema. The chest radiograph will often show pleural effusion, cardiomegaly, and bilateral “butterfly” pattern fluffy infiltrates, among other findings.

REF: p. 297 15. A patient has noncardiogenic pulmonary edema. What chest radiograph findings would be

expected?

1. “Bat’s wings” pattern fluffy infiltrates 2. Normal cardiac silhouette 3. Fluffy densities near the hilum 4. Pleural effusion a. 1 b. 2, 3 c. 3, 4 d. 1, 2, 4 ANS: B

A person with noncardiogenic pulmonary edema will have a normal cardiac silhouette and fluffy densities near the hilum. The chest radiograph of a person with cardiogenic pulmonary edema will show “bat’s wings” pattern fluffy infiltrates and pleural effusion.

REF: p. 297 16. The respiratory therapist is asked to evaluate a patient with suspected congestive heart

failure. Which of the following laboratory tests should the respiratory therapist recommend to evaluate the patient for possible congestive heart failure? a. Brain natriuretic peptide (BNP) b. Lactic dehydrogenase (LDH) c. Aspartate aminotransferase (AST) d. Alanine aminotransferase (ALT) ANS: A

The brain natriuretic peptide (BNP), also known as B-type natriuretic peptide or ventricular natriuretic peptide (still BNP) is an important biomarker used to help establish the diagnosis of congestive heart failure (CHF). The BNP hormone is produced by the heart and reflects how well the heart is functioning. Normally, only a low amount of BNP (<100 pg/mL) is found in blood. However, when the heart is working harder than normal over a long period of time, it releases more BNP, increasing the blood level of BNP. The other laboratory tests are not used for congestive heart failure.

All of the following may be causes of cardiogenic pulmonary edema EXCEPT: a. dysrhythmias. b. systemic hypertension. c. congenital heart defects. d. excessive fluid administration. e. pulmonary embolism.

ANS: E

Pulmonary embolism may cause noncardiogenic pulmonary edema. All of the other listed options may cause cardiogenic pulmonary edema.

REF: p. 295 18. The respiratory therapist is asked to recommend a medication to reduce afterload for a

patient with cardiogenic pulmonary edema. The therapist could recommend all of the following EXCEPT: a. captopril. b. norepinephrine (Levophed). c. enalapril (Vasotec). d. nitroprusside (Nitropress).

ANS: B

Afterload reducers include the following: • captopril—prevents the conversion of angiotensin I to angiotensin II. It is a potent vasodilator. Afterload and cardiac output usually improve in 10 to 15 minutes.

• enalapril (Vasotec)—is a competitive ACE inhibitor and reduces angiotensin II levels.

• nitroprusside (Nitropress)—is a potent, direct smooth muscle-relaxing agent that primarily reduces afterload.

Norepinephrine (Levophed) may be used in the management of cardiogenic pulmonary edema; however, it is a positive inotropic agent, not an afterload reducer.

a: a. b. c. d.

pulmonary embolism. pleural effusion. pulmonary infarction. pulmonary empyema.

ANS: C

A pulmonary infarction causes the death of lung tissue. This can happen when a pulmonary embolism (a clot that moves from another part of the body to the lung) significantly disrupts pulmonary blood flow. A pleural effusion is the leakage of fluid into the pleural space around a lung. An empyema is the accumulation of pus in the pleural space.

REF: p. 303 2. Bronchospasm may happen after a pulmonary embolism. Which of the following can lead to

this bronchospasm?

1. Localized hypoxemia 2. Localized hypercapnia 3. Localized hypocapnia 4. Release of cellular mediators from platelets a. 1, 2 b. 2, 4 c. 1, 3 d. 1, 3, 4 ANS: D

A pulmonary embolism can result in hypocapnia and hypoxemia in the local alveoli. In addition, there is the release of cellular mediators from platelets. All of these can cause bronchospasm.

REF: p. 303 3. A pulmonary embolism causes which of the following major pathologic and structural

changes in the lungs?

1. Alveolar consolidation 2. Mucosal edema 3. Alveolar atelectasis 4. Pleural friction rub a. 1, 3 b. 2, 4 c. 2, 3, 4 Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins d. 1, 2, 3, 4 ANS: A

After a pulmonary embolism, alveolar consolidation and atelectasis can occur. Mucosal edema is associated with asthma. Pleural friction rub is associated with an empyema.

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins REF: p. 304 7. The best test for diagnosing a suspected pulmonary embolism is a(n): a. spiral computerized tomography scan. b. pulmonary function test. c. electrocardiogram. d. chest radiograph.

ANS: A

A spiral computerized tomography scan can quickly identify a pulmonary embolism because it makes a three-dimensional image of the lungs and pulmonary circulation. Pulmonary function testing, electrocardiogram, and chest radiograph are not helpful because they do not provide specific indicators of a pulmonary embolism.

REF: p. 305 8. A pulmonary angiogram is usually ordered: a. as the first test to identify a pulmonary embolism. b. when other tests for a pulmonary embolism are inconclusive. c. in conjunction with a magnetic resonance image to identify a pulmonary

embolism. d. in conjunction with an extremity venogram to identify a pulmonary embolism.

ANS: B

If other, simpler tests are inconclusive, a pulmonary angiogram is usually ordered to accurately identify a pulmonary embolism. It is not combined with any other testing.

REF: p. 306 9. A patient’s D-dimer blood test results show a value of 250 ng/mL. How should these results

be interpreted? a. The patient does not have a pulmonary embolism. b. The patient’s anticoagulant level is acceptable. c. The patient has a pulmonary embolism. d. The patient has a deep vein thrombosis.

ANS: A

With this low D-dimer value, a pulmonary embolism can be ruled out. A D-dimer value of greater than 500 ng/mL is considered positive for a pulmonary embolism.

REF: p. 305 10. The duplex venous ultrasonography test is used to: a. diagnose a blood clot below the knee. b. identify a saddle embolism. c. diagnose a blood clot behind the knee or thigh. d. identify a pulmonary infarction.

1. Urokinase 2. Vitamin K 3. Heparin 4. Streptokinase a. 1, 4 b. 2, 3 c. 1, 3, 4 d. 1, 2, 3, 4 ANS: A

Fibrinolytic agents such as streptokinase (Streptase), urokinase (Abbokinase), alteplase (Activase), and reteplase (Retavase) actually dissolve blood clots. These agents (commonly referred to as “clot-busters”) have proved beneficial in treating acute pulmonary embolism.

Heparin is an anticoagulant, not a fibrinolytic. Vitamin K does affect clotting time but is not given therapeutically to break up an existing blood clot.

REF: p. 311 12. All of the following are preventive measures taken with patients at high risk for

thromboembolic disease EXCEPT: Drink lots of water.

Dangle your legs over the edge of the bed before getting up.

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Three things can lead to pulmonary hypertension after a pulmonary embolism: less area for blood to flow through, alveolar hypoxia, and released humoral agents (serotonin and prostaglandin). Baroreceptors are stimulated by hypotension and cause the heart rate to increase.

REF: pp. 309-310 14. The respiratory therapist is listening to the heart sounds of a patient with a

suspected pulmonary embolus. The therapist could expect to hear all of the following EXCEPT: a. increased second heart Sound (S2). b. increased splitting of the second heart sound (S2). c. third heart sound (S3). d. fourth heart sound (S4).

ANS: D

As a result of the pulmonary embolus and the increase in pulmonary vascular resistance, the following heart sounds could be expected: increased second heart sound (S2), increased splitting of the second heart sound (S2), and third heart sound (ventricular gallop). The fourth heart sound would not be an expected finding.

REF: pp. 308-309 15. In order to prevent pulmonary emboli, a filter may be placed into which of the following

vessels to prevent clots from being carried into the pulmonary circulation?

Subclavian vein Pulmonary artery Thoracic duct Inferior vena cava Femoral artery

a. b. c. d. e.

ANS: D

An inferior vena cava vein filter may be surgically placed in the inferior vena cava to prevent clots from being carried into the pulmonary circulation. The effectiveness and safety of these filters are not well established and, in general, they are only recommended in some high-risk patients. Edema distal to the filters is a complicating factor.

REF: p. 311 16. All of the following medications may be used to prevent pulmonary emboli EXCEPT: a. enoxaparin. b. dalteparin. c. tinzaparin. d. reteplase.

ANS: D

Enoxaparin, dalteparin, and tinzaparin are all low–molecular weight heparins that are anticoagulants used in the prevention of pulmonary emboli. Reteplase is a thrombolytic used in the treatment, not prevention, of pulmonary emboli.

respiratory therapist should advise the patient to avoid eating all of the following EXCEPT: a. broccoli. b. spinach. c. liver. d. grapefruit. e. orange juice.

ANS: E

Patients on warfarin should be advised to avoid foods that are high in vitamin K (which affects blood clotting), such as broccoli, spinach and other leafy green vegetables, liver, grapefruit, and grapefruit juice. Green tea may also need to be avoided. Orange juice is high in potassium, but this is unrelated to warfarin therapy.

REF: p. 311 18. A pulmonary embolus produces which of the following a. True shunting b. Shunt effect c. Dead space effect d. True dead space

/ abnormalities?

ANS: D

When an embolus lodges in the pulmonary vascular system, blood flow is reduced or completely absent distal to the obstruction. Consequently the alveolar ventilation beyond the obstruction is wasted, or dead space, ventilation, and no carbon dioxide–oxygen exchange occurs. The ventilation-perfusion distal to the pulmonary embolus is high and may even be infinite if there is no perfusion at all.

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins b. Hemorrhage c. Pulmonary edema d. Alveolar atelectasis ANS: D

Compression of the lung tissue occurs beneath the flail section and atelectasis results. The atelectasis then results in a decreased ventilation/perfusion ratio leading to increased venous admixture. Hypoxemia will occur.

REF: p. 324 9. Which of the following statements is TRUE regarding paradoxical chest movement? a. With inspiration, the flail section moves outward. b. The trachea deviates away from the flail side of the chest. c. During inspiration, the flail section moves inward. d. During exhalation, the flail area moves inward.

ANS: C

Paradoxical chest movement means that the flail area moves in the opposite direction from which it normally would. So, with inspiration, the flail area moves inward, and with exhalation, the flail area moves outward. The tracheal position is not affected by broken ribs.

REF: p. 322 10. When a patient has a flail chest, what happens during the ventilatory cycle? a. The I:E ratio becomes inverse. b. Air leaks out through the flail area. c. Air leaks in through the flail area. d. Air is shunted from one lung to the other.

ANS: D

Because of the instability of the flail area, the ribs and lung tissue will move in the opposite direction than normal during a breath. This can cause air to be shunted from one lung to the other during the ventilatory cycle.

REF: p. 432 8. A CPAP titration polysomnogram is performed to: a. find the maximum CPAP level for the functional residual capacity. b. determine the lowest possible CPAP level. c. find the CPAP level to maintain an open airway. d. determine the pressure needed for negative-pressure ventilation.

ANS: C

A CPAP titration polysomnogram is performed to find the CPAP level to maintain an open airway. The CPAP is delivered to the patient through a nasal (or full face) mask. If the CPAP level is too low, the airway will tend to still collapse. Too high a CPAP level puts unnecessary pressure on the lungs and heart. The CPAP level is not used to set the pressure for negativepressure ventilation.

REF: p. 425 |p. 428 9. First-line treatment for the management of hyperventilation-related central sleep

apnea includes: CPAP. adaptive servo-ventilation (VPAP). mechanical ventilation. palatopharyngoplasty.

a. b. c. d.

ANS: A

Similar to OSA, continuous positive airway pressure (CPAP) has customarily been the firstline therapy for patients with hyperventilation-related CSA. Patients who do not respond well to CPAP should receive a trial of adaptive servo-ventilation (ASV) with the variable positive airway pressure adapt (VPAP Adapt).

REF: pp. 434-435 10. Which of the following may be used in the management of a patient with central sleep apnea?

1. Acetazolamide 2. Oxygen therapy 3. Inhaled bronchodilator medications 4. Adaptive servo-ventilation (VPAP) a. 1, 3 Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins c. 1, 2, 4 d. 1, 2, 3, 4 ANS: C

Respiratory stimulants (like acetazolamide), supplemental oxygen, and adaptive servoventilation may be used in the management of a patient with central sleep apnea. Inhaled bronchodilator medications are not helpful because the patient’s problem is not caused by bronchospasm.

REF: p. 434 11. During a pulmonary function study, it was found that a patient has a sawtooth pattern on

his flow-volume loop. What is this finding associated with? a. Central sleep apnea b. COPD c. Obstructive sleep apnea d. Laryngeal edema (epiglottitis) ANS: C

An inspiratory sawtooth pattern on the flow-volume loop is associated with obstructive sleep apnea. The sawtooth pattern is caused by loose tissues in the throat moving during the rapid inspiration. Patients with COPD have a distinctively slow expiratory flow pattern. A patient with laryngeal edema (epiglottitis) will often have a distinctive inspiratory stridor sound.

REF: p. 430 12. Sleep apnea is associated with:

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins REF: p. 431 14. The respiratory therapist is evaluating a patient for risk of obstructive sleep apnea. All of

the following are risk factors for obstructive sleep apnea EXCEPT: a. excess weight. b. neck size. c. hypertension. d. hypoglycemia. e. chronic nasal congestion.

ANS: D

More than 50% of the patients diagnosed with obstructive sleep apnea are overweight. It is suggested that fat deposits around the upper airway may obstruct breathing. Obstructive sleep apnea is often seen in the patients with large neck size. A neck circumference greater than 17 inches in males and greater than 16 inches in females increases the risk for obstructive sleep apnea. Obstructive sleep apnea is commonly seen in patients with high blood pressure.

Obstructive sleep apnea occurs twice as often in patients with chronic nasal congestion from any cause. Patients with diabetes, not hypoglycemia, are three times more likely to have obstructive sleep apnea than healthy individuals.

REF: p. 424 15. All of the following may be an advantage of in-home portable sleep testing EXCEPT: a. convenience. b. patient acceptance. c. can be easily performed over multiple nights. d. decreased cost. e. published standards for scoring or interpretation.

ANS: E

Advantages of in-home portable monitoring include: it can be done in the patient’s home and/or in areas without ready access to sleep centers, convenience, patient acceptance, and decreased cost. A disadvantage is that there are no published standards for scoring or interpretation.

REF: pp. 428-429 16. The rationale behind the use of supplemental oxygen in the treatment of sleep apnea is to: a. preoxygenate the airway prior to the apneic episodes. b. stimulate the central chemoreceptors and prevent apneic episodes. c. increase the respiratory drive in the medulla. d. blow off carbon dioxide in the alveolus.

ANS: A

Because of the hypoxemia-related cardiopulmonary complications of sleep apnea (arrhythmias and pulmonary hypertension), nocturnal low-flow oxygen therapy is sometimes used alone to offset or minimize the oxygen desaturation. The reasoning behind the use of nasal oxygen therapy’s effectiveness is that the airway is continually “flooded” with oxygen, which will be inspired during the nonapneic episodes—in effect, “preoxygenating” the patient in anticipation of the apnea events. Usually, no improvement in sleep fragmentation or Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

2. substernal retractions.

3. expiratory grunting.

4. apnea. a. 1, 3 b. 2, 4 c. 2, 3, 4 d. 1, 2, 3 ANS: D

Early on, when an infant is having respiratory distress, he or she will show cyanosis, sternal retractions, expiratory grunting, and other signs. He or she will have apnea and other signs later on.

REF: p. 446 2. Late clinical manifestations of an infant with respiratory distress include:

1. elevated diaphragm.

2. decreased respiratory rate.

3. CO2 retention.

4. lethargy. a. 2, 3 b. 1, 4 c. 1, 2, 3 d. 1, 2, 3, 4 ANS: A

Late clinical manifestations that an infant is having respiratory distress include decreased respiratory rate, CO2 retention, and other signs. He or she will have lethargy and other signs early on. Elevated diaphragm is not an early or late sign of respiratory distress.

REF: p. 446 3. An infant in respiratory distress will often generate a high negative intrapleural pressure

during inspiration. In comparison to an adult, this will result in all of the following EXCEPT: cyanosis of dependent thoracic areas. “seesaw” breathing pattern. alveolar hyperinflation. intercostal retractions.

a. b. c. d.

ANS: C

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Alveolar hyperinflation is associated with air trapping. A high negative intrapleural pressure can result in cyanosis of dependent thoracic areas, “seesaw” breathing pattern, and intercostal retractions.

REF: p. 447 4. A neonate in respiratory distress will often dilate his or her nostrils to: a. facilitate inspiration. b. nurse more easily. c. sneeze out amniotic fluid. d. raise the intrapleural pressure.

ANS: A

Dilation of the nostrils will make inspiration easier in the premature neonate. None of the other listed options are affected by dilated nostrils.

REF: p. 447 5. A neonatal patient is found to have grunting on expiration. What physiologic effect does this

produce?

Increased vital capacity Increased PAO2 Decreased PaCO2 Closes the ductus arteriosus

a. b. c. d.

ANS: B

An expiratory grunt is the sound generated when expired air is moving through a partially closed glottis. This partial closing of the glottis applies positive pressure against the alveoli.

An increased PAO2 should result. Glottis closure will not increase vital capacity, decrease PaCO2, or close the ductus arteriosus.

REF: p. 447 6. Apnea of prematurity can be defined as:

1. respiratory pause causing bradycardia.

2. cycles of short breathing pauses followed by faster breathing.

3. no breathing for >20 seconds.

4. sudden apnea and death (crib death). a. 4 b. 2 c. 1, 3 d. 3, 4 ANS: C

Apnea has two possible definitions: (1) respiratory pause causing bradycardia (or cyanosis or both) and (2) no breathing for less than 20 seconds. Apnea is usually found in a baby of less than 37 weeks’ gestation. Period breathing is described as cycles of short breathing pauses followed by faster breathing. Sudden apnea and death (crib death) cases are usually associated with upper airway obstruction in an infant lying on its stomach or entangled with bed linens.

4. Ductus arteriosus a. 2 b. 1, 3 c. 2, 4 d. 1, 2, 4 ANS: C

During PPHN, blood will flow through the foramen ovale and ductus arteriosus to bypass the lungs. Fetal circulation involves blood passing through the foramen ovale, ductus arteriosus, ductus venosus, and hypogastric arteries. See Figure 31-3.

REF: p. 444 11. PPHN usually appears: a. in utero during the last trimester. b. within 1 hour of birth. c. within the first 12 hours of birth. d. between the 1st and 6th days of life.

Normal adjustment to being born Moderate distress; intubate the airway and suction the lungs Moderate distress; administer supplemental oxygen Severe distress; begin bag-mask resuscitation

ANS: A

A 5-minute Apgar score of 7 to 10 indicates no difficulty in adjusting to extrauterine life. A score of less than 7 indicates some difficulty. Additional steps will need to be taken to resuscitate the neonate depending on the severity of the situation.

REF: pp. 449-450 15. A premature infant is found to be “bobbing” her head. This is important because it can be

a sign of which of the following?

Hypoxemia Renal failure Intracranial hemorrhage Respiratory distress Septic shock

a. b. c. d. e.

ANS: D

Head bobbing is a sign of respiratory distress in an infant. When in respiratory distress, the infant often uses the scalene and sternocleidomastoid accessory muscles of inspiration to assist in ventilation. When these muscles contract, the infant’s head moves (“bobs”) back and forth because the neck extensor muscles are not strong enough to stabilize the head.

REF: p. 447 16. A premature infant has two pulse oximeters placed: one on the right hand and one on the left

foot. The respiratory therapist notes that the reading on the right hand is consistently 12% greater than the reading on the left foot. Which of the following is the best interpretation of this finding? a. The infant has left-sided intra-pulmonary shunting. b. The infant likely has pneumonia. c. The infant is in septic shock with systemic capillary shunting. d. The infant has persistent pulmonary hypertension of the newborn. e. The infant has shunting across the ductus venosus.

ANS: D

For the newborn in respiratory distress, pulse oximetry is often used to monitor both the preductal SpO2 and the postductal SpO2. To measure the preductal SpO2, the oximeter probe is placed on the right hand or wrist; to measure the postductal SpO2, the probe is placed on either foot. A large difference between the two readings (>10%) indicates a right-to-left shunt, and persistent pulmonary hypertension of the newborn (PPHN) is likely.

REF: p. 445 17. A premature infant is suspected of having persistent pulmonary hypertension of the newborn.

How is this diagnosis confirmed? a. Arterial blood gas analysis

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins c. Pulmonary angiography d. Echocardiography e. Cardiac catheterization ANS: D

The diagnosis of PPHN should always be suspected in any infant with nonresponsive or ongoing hypoxemia and cyanosis that is out of proportion to the degree of pulmonary disease, oxygen requirement, and mean airway pressure support. The diagnosis of PPHN is confirmed by echocardiography. When PPHN is present, echocardiography demonstrates normal structural cardiac anatomy with evidence of pulmonary hypertension (e.g., flattened or displaced ventricular septum). Doppler studies show right-to-left shunting through the patent ductus arteriosus and/or foramen ovale.

Chapter 35. Meconium Aspiration Syndrome Des Jardins: Clinical Manifestations and Assessment of Respiratory Disease, 8th Edition MULTIPLE CHOICE 1. How may a fetus respond when he or she becomes hypoxemic? a. The fetus stops making breathing efforts. b. The fetus makes rapid, shallow chest movements. c. The fetus makes very deep, gasping inspiratory movements. d. The fetus shows Kussmaul respirations.

ANS: C

When a fetus is experiencing hypoxemia, he or she will make very deep, gasping inspiratory movements. As a result, the fetus will inhale amniotic fluid or meconium. Kussmaul respirations are related to diabetic ketoacidosis.

airways?

Air trapping on exhalation Apnea of prematurity Air trapping on inhalation Bronchiectasis

a. b. c. d.

ANS: A

A “ball-valve” effect in the small airways will cause air trapping on exhalation. In other words, air will be inhaled but cannot be fully exhaled. Apnea of prematurity and bronchiectasis are not related to the “ball-valve” effect.

REF: pp. 463-464 3. A patient has meconium aspiration syndrome (MAS) and a chemical pneumonitis as a result.

this?

Status asthmaticus Persistent pulmonary hypertension of the newborn (PPHN) Bronchopulmonary dysplasia (BPD) Pulmonary fibrosis

a. b. c. d.

ANS: B

MAS can cause hypoxemia, which, in turn, can lead to PPHN. Hypoxemia will not cause status asthmaticus, BPD, or pulmonary fibrosis.

Risk factors for the development of MAS include, but are not limited to, the fetus being postterm (or full-term) and the mother being hypertensive or toxemic. MAS is not directly related to the first twin (or second twin) born.

REF: p. 464 8. Indications that a newborn has aspirated meconium include all of the following EXCEPT: a. high Apgar score. b. meconium in amniotic fluid. c. newborn is not actively breathing. d. meconium staining on skin.

ANS: A

A high Apgar score indicates that the infant is adapting well to being born. A low Apgar score indicates the infant is having difficulty without being specific about the cause. An apneic newborn with obvious signs of meconium would give a strong indication of meconium aspiration.

REF: p. 466 9. It is highly suspected that a newborn has aspirated meconium. What actions should be

immediately undertaken?

1. Instill exogenous surfactant.

2. Suction out the meconium.

3. Begin mechanical ventilation.

4. Intubate the infant. a. 2, 4 b. 1, 2 c. 2, 3, 4 d. 1, 2, 3, 4 ANS: A

If a newborn has aspirated meconium, it must be immediately removed. This is best done by inserting an oral endotracheal tube into the newborn’s trachea and passing a suction catheter through the tube to suction out the meconium. In most cases, this will eliminate the need for mechanical ventilation. Some infants with severe meconium aspiration will need to be mechanically ventilated and given exogenous surfactant.

REF: pp. 466-467 10. What risk(s) is (are) there in positive-pressure ventilation before all meconium has been

removed from the airways?

1. Forcing meconium into the lower airways 2. Pneumothorax 3. Triggering persistent pulmonary hypertension of the neonate (PPHN) 4. Triggering an asthma attack a. 2 b. 3 c. 1, 2 Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins ANS: C

Positive-pressure ventilation can force any meconium from the upper airway down into the smaller airways. This can result in a “ball-valve” type of obstruction to exhalation. The trapped air can cause hyperinflation that can lead to a pneumothorax. PPHN and asthma are not linked to positive-pressure ventilation.

REF: pp. 466-467 11. If mechanical ventilation is needed to support a neonate with MAS, which of the following

settings is especially important? a. High positive end-expiratory pressure (PEEP) level b. Long exhalation time c. High humidity level d. Give no more than 50% oxygen ANS: B

Because of the risk of incomplete exhalation with MAS, the infant receiving mechanical ventilation must have a long exhalation time. It is important to confirm that there is complete exhalation of the delivered tidal volume. PEEP is not usually needed with the MAS patient.

All patients receiving mechanical ventilation should be given a fully humidified tidal volume.

Follow the oxygen therapy protocol to guide delivery of the necessary oxygen percentage.

More than 50% oxygen may be needed until the infant’s airways are open.

REF: p. 467 12. A common finding in a neonate with MAS is a respiratory rate that is: a. under 40/min. b. between 40 and 60/min. c. well over 60/min. d. cyclical with faster and then slower breaths.

ANS: C

It is common to find an infant with MAS to have a respiratory rate of well over 60/min. A normal infant will have a respiratory rate between 40 and 60/min. A cyclical breathing pattern would be seen in an infant with periodic breathing.

REF: p. 465 13. An infant with MAS will show what clinical manifestations associated with the more negative

intrapleural pressures needed during inspiration?

1. Seesaw breathing movement 2. Breath sounds reveal rhonchi and crackles 3. Expiratory grunting 4. Cyanosis of the dependent thoracic areas a. 1, 4 b. 2, 3 c. 2, 3, 4 d. 1, 2, 3, 4 ANS: A

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Clinical manifestations associated with the more negative intrapleural pressures needed during inspiration include, but are not limited to, seesaw breathing movement and cyanosis of the dependent thoracic areas. Chest assessment findings may include rhonchi and crackles for breath sounds because of meconium in the airways. If the neonate is hypoxic, he or she may display expiratory grunting. However, these last two findings are not directly associated with the more negative intrapleural pressures needed during inspiration.

REF: p. 465 14. A patient with MAS has had a chest radiograph taken. What findings can be expected? a. Elevated diaphragms b. Mediastinal shift c. Irregular densities throughout the lungs d. Air bronchograms ANS: C

Meconium in the airways will be seen on the chest radiograph as irregular densities throughout the lungs. An infant with MAS is more likely to have depressed diaphragms due to air trapping. There should not be any mediastinal shift with MAS. Air bronchograms are associated with diffuse atelectasis, not MAS. REF: p. 466 15. Hyperinflation is noted on the chest radiograph of a patient with MAS. What sudden

Chapter 37. Respiratory Distress Syndrome Des Jardins: Clinical Manifestations and Assessment of Respiratory Disease, 8th Edition MULTIPLE CHOICE 1. Respiratory distress syndrome (RDS) primarily affects infants who are: a. preterm with insufficient surfactant. b. full-term. c. postterm with too much surfactant. d. preterm with too much surfactant.

ANS: A

RDS is found in preterm neonates with insufficient surfactant. Surfactant is produced by the alveolar type II cells in the lungs of a full-term (or near-term) neonate.

REF: p. 476 2. Which of the following is usually seen in the lungs of a neonate with RDS? a. Alveolar collapse (atelectasis) b. Segmental atelectasis c. Lobar atelectasis d. Pulmonary fibrosis ANS: A

RDS is caused by the lack of surfactant within the alveoli of the neonate. This leads to alveolar collapse (atelectasis). Segmental or lobar atelectasis is associated with a bronchial obstruction by a foreign body. Pulmonary fibrosis is not associated with RDS. REF: p. 477 3. The hyaline membrane seen in the alveoli of a neonate with RDS is similar to the anatomic

alteration found in what other pulmonary disease?

Bacterial pneumonia Pulmonary fibrosis Acute respiratory distress syndrome (ARDS) Meconium aspiration syndrome (MAS)

a. b. c. d.

ANS: C

The hyaline membrane containing fibrin and cellular debris is the same in RDS and ARDS. Bacterial pneumonia, pulmonary fibrosis, and MAS will have other types of pulmonary changes.

REF: p. 476 4. What vascular anatomic alteration could occur as a consequence of hypoxia in a patient

with RDS? a. Closure of the ductus arteriosus b. Transient pulmonary hypertension c. Increased flow through the ductus venosus Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins d. Airway mucosal edema ANS: B

Hypoxia can induce arterial vasoconstriction leading to transient pulmonary hypertension.

This can lead to blood shunting through an open ductus arteriosus. Because the neonate has been born, the ductus venosus will remain closed. Hypoxia will not cause airway mucosal edema.

REF: p. 476 5. What is the primary cause of RDS in the newborn? a. Underdevelopment of alveolar type I cells b. Deficiency or abnormality of pulmonary surfactant c. Hypoxia causing pulmonary hypoperfusion d. Excessive amniotic fluid in the lungs ANS: B

RDS is caused by the abnormality or deficiency of pulmonary surfactant from the alveolar type II cells. It is most likely that pulmonary hypoperfusion is a secondary response to the surfactant abnormality and related hypoxia. Alveolar type I cells allow for easy gas exchange and do not produce surfactant. Transient tachypnea of the newborn (TTN) is caused by the delayed absorption of fetal amniotic lung fluid.

REF: p. 476 6. A patient with RDS has alveolar hypoxia and pulmonary vasoconstriction. How will this

affect his blood flow?

1. Blood shunts through the foramen ovale 2. Increased systemic blood flow 3. Blood shunts through the ductus arteriosus 4. Decreased blood flow to the gut a. 2, 4 b. 1, 3 c. 1, 2, 3 d. 1, 2, 3, 4 ANS: B

As a consequence of alveolar hypoxia, the neonate can develop pulmonary vasoconstriction and transient pulmonary hypertension. This will lead to a right-to-left shunt as blood flows through the foramen ovale and ductus arteriosus. This results in a partial return to fetal circulation. There is no change in systemic blood flow and flow to the gut.

REF: p. 476 7. Which of the following are associated with an increased risk of developing RDS?

1. Low–birth weight infant 2. Prenatal asphyxia 3. Maternal bleeding 4. Second-born twin a. 1, 2 Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins c. 2, 3, 4 d. 1, 2, 3, 4 ANS: D

All of the listed conditions, and others, increase the risk of the neonate developing RDS. REF: p. 478 8. All of the following amniotic fluid lab findings would indicate mature fetal lungs EXCEPT: a. S:A ratio is >55. b. PG is present. c. L:S ratio is 2:1. d. L:S ratio is 1:2.

ANS: D

An L:S ratio of 1:2 (anything less than a 2:1 ratio) would indicate immature lungs and increased risk of RDS. Mature fetal lungs are indicated by an S:A ratio of >55, the presence of PG, and an L:S ratio of 2:1 or greater.

REF: p. 478 9. The neonate with RDS would have a phosphatidylglycerol (PG) level that is: a. present. b. absent. c. above normal. d. below normal.

ANS: B

PG is the second most abundant phospholipid in surfactant. The absence of PG in amniotic fluid would indicate immature lungs, as would be the case in a neonate with RDS. The presence of PG would indicate mature lungs with surfactant.

REF: p. 478 10. What special environmental concerns are there with a neonate with RDS in order to

avoid compromising his or her oxygenation?

Keeping a normal body temperature Placing a bilirubin light on the neonate Keeping the infant cool Humidifying the inhaled oxygen

a. b. c. d.

ANS: A

Maintain the neonate’s normal body temperature to avoid compromising its oxygenation.

Avoid having the neonate either too cool or too warm. Bilirubin lights have no effect on oxygenation. Inhaled oxygen should be humidified to avoid the drying of secretions.

REF: p. 580 11. A mother is about to deliver a 25-weeks’ gestation infant. What therapeutic intervention

should the respiratory therapist be prepared to give to minimize the risk of RDS? a. Mask CPAP Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins c. Exogenous surfactant d. Mechanical ventilation ANS: C

It is very likely that a 25-weeks’ gestation age infant will develop RDS. In this situation, exogenous surfactant should be given as soon as possible to prevent pulmonary complications.

Airway suctioning will be performed to remove airway fluids but will not prevent RDS. Giving exogenous surfactant should help to minimize the need for CPAP or mechanical ventilation.

REF: p. 580 12. Management of a neonate with RDS may include:

1. CPAP. 2. instilling surfactant into the lungs.

3. mechanical ventilation.

REF: p. 479 14. A patient has RDS. What clinical manifestations are associated with the more negative

intrapleural pressures needed during inspiration?

1. Seesaw breathing movement 2. Vesicular breath sounds 3. Pulmonary edema 4. Dependent thoracic areas are cyanotic a. 1, 4 b. 2, 4 Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins c. 1, 2, 3 d. 1, 2, 3, 4 ANS: A

Clinical manifestations associated with the more negative intrapleural pressures needed during inspiration include, but are not limited to, seesaw breathing movement and cyanosis of the dependent thoracic areas. It is unlikely that your patient will have normal, vesicular breath sounds. Pulmonary edema is not associated with RDS. REF: p. 479 15. It is likely that a neonate with RDS will have which of the following chest radiograph

findings? a. Airway dilation and distortion b. Fluffy infiltrates in the bases of the lungs c. Ground-glass appearance d. Cardiomegaly ANS: C

RDS causes alveolar atelectasis. This will be seen on the chest radiograph as a white density of the lung fields that will appear as a fine ground-glass appearance. Airway dilation and distortion are associated with bronchiectasis. Fluffy infiltrates in the bases of the lungs are commonly seen in a patient with pulmonary edema. Cardiomegaly is an enlarged heart and is associated with right- or left-sided heart failure.

REF: p. 580 16. A premature infant with RDS is receiving mechanical ventilation. In managing the patient’s

oxygenation, the respiratory therapist should strive to keep the PaO2 at: between 25 and 50. between 40 and 70. between 80 and 100.

95 or greater.

a. b. c. d.

REF: p. 580 17. In assessing a patient with RDS, the respiratory therapist would expect to find all of the

following EXCEPT: a. intercostal retractions. b. acrocyanosis. c. flaring nostrils. d. wheezing. e. cyanosis.

ANS: D

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

Test Bank for Clinical Manifestations and Assessment of Respiratory Disease 8th Edition Jardins

The following signs may be found in an infant with RDS: intercostal retractions, substernal retraction and abdominal distention (seesaw movement), acrocyanosis mottling and cyanosis of the dependent portions of the thoracic and abdominal areas, flaring nostrils, bronchial (or harsh) breath sounds, fine crackles, and cyanosis. Wheezing would not be expected because bronchospasm is not part of the pathophysiology of RDS. REF: p. 479 18. The standard of care to evaluate the oxygenation status of a premature infant with RDS is by: a. capillary blood gas (CBG). b. arterial blood gas (ABG). c. capnography. d. pulse oximetry. e. transcutaneous monitoring.

ANS: D

Because of the difficulty of obtaining arterial blood gas (ABG) samples from newborn and pediatric patients, capillary blood gas (CBG) samples are usually used to determine the pH, PaCO2, and HCO3 - (i.e., the acid-base and ventilation status only). Capillary PO2 values are unreliable and should not be used for clinical analysis. The standard practice of care to evaluate the oxygenation status in these young patients is pulse oximetry (SpO2).
