11. Which units can provide high-quality and cost-effective care for

patients who are less complex, more stable, and have a decreased need for physiologic monitoring? a. Intensive care units b. Triage units c. Progressive care units d. Medical surgical units ANS: c

A growing trend in acute care settings is the designation of progressive care units, considered to be part of the continuum of critical care. These units can serve as a bridge between intensive care units and medical-surgical units, while providing high-quality and cost-effective care at the same time. Patients who are ideal candidates for progressive care are less complex, more stable, have a decreased need for physiologic monitoring, and more self-care capabilities.

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

b. Availability of staff and facility equipment c. Research evidence on the topic d. Patient knowledge of the disease e. Patient preference regarding care ANS: a,c,e

Evidence-based nursing practice considers the best research evidence on the care topic along with clinical expertise of the nurse and patient preferences. For instance, when determining the frequency of vital sign measurement, the nurse would use available research and nursing judgment (stability, complexity, predictability, vulnerability, and resilience of the patient). Availability of staff and facility equipment and the patient's knowledge of the disease do not factor into evidence-based nursing practices.

nurse wants to provide her with some basic information before going in the room to talk about her specific procedure. Which teaching strategy is most appropriate for this situation? a. Discussion b. Demonstration and practice c. Audiovisual media d. Written materials ANS: c

Media are used to educate patients on a variety of educational needs, such as medications, disease processes, procedures, symptom management, weight monitoring, laboratory tests, diet, surgery, and health maintenance issues. Patient education videos require the patient's attention for only a few minutes and supply the learner with "nice-to-know" and "need-to-know" information. Demonstration and practice is not appropriate for this procedure because the patient is not performing the cardiac catheterization.

care unit? a. Provide a variety of caregivers to enhance the availability of different

information. b. Allow frequent uninterrupted rest periods to enhance obtaining structured sleep. c. Provide the patient lists of facts that can enhance understanding of the disease. d. Teach according to a structured plan to enhance comprehension.

ANS: b

Sleep cycle alterations caused by sleep deprivation or sensory overload related to continuous noise from machines or people affect the patient's ability to concentrate and comprehend information. Allowing frequent uninterrupted rest periods assists the patient in obtaining structured sleep. Assignment of multiple caregivers may negatively affect the ability of the patient and family to form a trusting relationship with the nursing staff. Teach whatever the patient wants to learn and avoid lists of facts.

Behaviors such as handing a form to family member to complete, claiming to be too tired, or "forgetting" one's glasses are a few behaviors that may be used by individuals to hide their limitations or low health literacy. Word recognition tests consist of lists of health care terms that patients are asked to read. Reading comprehension tests assess understanding of health care information presented but do not demonstrate the individual's ability to apply this information. Functional health literacy tests assess the individual's level of comprehension and ability to put into action what he or she has learned.

weaned. As she begins to wake up for the first time, she becomes increasingly agitated, pulling at her gown, kicking her feet, and grimacing. What action should the nurse take next? a. Administer additional sedation until the patient stops kicking. b. Initiate wrist restraints to prevent the patient from pulling. c. Tell the patient to stop moving around to avoid accidental extubation. d. Provide the patient with simple facts to assist with understanding of

the situation.

ANS: d

The need for oxygen and survival predominates over all other human needs. According to Maslow's hierarchy of human needs, lower-level, physiologic needs must be satisfied before an individual can move on to higher-level issues.

medications? c. Do you take all your medications? d. Do you ever miss taking your medication?

ANS: b

Open-ended questions provide the nurse an opportunity to assess actual knowledge gaps rather than assume knowledge by obtaining a yes or no response. These types of questions also assist the patient and family to tell their story of the illness and communicate their perceptions of the experience. Questions that elicit only a yes or no response close off communication and do not provide for an interactive teaching-learning session.

do first when confronted by stress? a. Determines coping mechanisms to deal with the stress. b. Determines the perceived degree of threat imposed. c. Determines what the response will be to the stress. d. Denies the stress exists.

ANS: b

An alarm reaction is initiated by the hypothalamus, which, upon receiving sensory and chemical information regarding the presence of a stressor, signals the release of corticotrophin-releasing factor (CRF).

During the resistance stage, the person's systems fight back, leading to adaptation and a return of normal functioning. If the stressors continue, exhaustion occurs, a stage in which reserves have been depleted.

Reversal of stress exhaustion can be accomplished by restoration of one's reserves through the use of medications, nutrition, and other stress reduction measures.

After an exposure to a traumatic event, people may experience intrusive recall of the distressing event. This recall is often triggered by a noise, sound, sight, smell, event, or memory. Nightmares and distressing memories during which a trauma is reexperienced provoke intense psychological and physiologic distress.

ANS: a

Regression allows patients to give up their usual roles, autonomy, and privacy to become passive recipients of medical and nursing care.

Behaviors such as whining, clinging to staff, needing the nurse constantly at the bedside, and giving evidence of an inability to self-modulate feelings of anxiety or fear can interfere with patient recovery and negatively impact nurse-patient relationships.

5. Which concept supports patients and helps them endure the physical

and psychological insults of their critical illness? a. Regression b. Denial c. Hope d. Trust ANS: c

Hope is a subjective, dynamic internal process essential to life.

Considered to be a spiritual process, hope is an energy that arises out of a sense of being meaningfully connected to one's self, others, and powers greater than the self. With hope, a person is able to transition from a state of vulnerability to a point of being able to live as fully as possible. Regression is an unconscious defense mechanism characterized by a retreat, in the face of stress, to behaviors characteristic of an earlier developmental level. Denial is defined as the "conscious and unconscious attempts to disavow knowledge or the meaning of an event to reduce anxiety and fear." Trust manifests itself in critical care patients' belief that the people they depend on will get them through the illness and will be able to manage any untoward event that might occur.

A suicide attempt indicates, however, that the patient was experiencing personal and spiritual distress to the point of wanting to end his or her life. The critical care team should make every effort to continue medications for mental health conditions during the critical care stay unless medically contraindicated.

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

Pain triggers anxiety, and increased anxiety intensifies pain experiences.

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

This reciprocal relationship varies, depending on whether pain is produced by disease processes or invasive procedures, is acute or chronic in nature, or if the pain is anticipated. Medications such as theophylline, anticholinergics, dopamine, levodopa, salicylates, and steroids can also contribute to feelings of anxiety. Self-esteem refers to how well one's behavior correlates with a sense of the ideal self and is most closely linked to one's sense of self-worth.

Stress management techniques help to restore energy and enjoyment in caring for patients. Nurses who practice self-care are more likely to experience professional and personal growth and find more meaning in their work. Maintain physical health by eating well, exercising, engaging in relaxing activities, laughing, and getting enough sleep. Promote emotional health by participating in calming activities, such as meditation, daily gratitude reflections, deep breathing, walking, or listening to music. Use self-transcendence (spiritual awareness) activities, such as journal writing, sharing stories, recognizing one's own positive contributions and unique gifts, and connecting with one's self.

Ignoring feelings of frustration and anger will only contribute to the problem.

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

d. Limit all nutrients to account for altered renal excretion.

ANS: c

Proteins and amino acids are removed during peritoneal dialysis, creating a greater nutritional requirement for protein. The renal patient must receive an adequate amount of protein to prevent catabolism of body tissues to meet energy needs. Approximately 1.5 to 2.0 g protein/kg/day is required. Certain nutrients such as potassium and phosphorus are restricted because they are excreted by the kidney. The patient has no specific requirement for the fat-soluble vitamins A, E, and K because they are not removed in appreciable amounts by dialysis, and restriction generally prevents development of toxicity.

Adding insulin to the TPN c. Weaning from the TPN over a 6-hour period d. Starting an infusion of 0.9% normal saline ANS: b

One method for controlling hyperglycemia in a patient receiving TPN is to add insulin to the infusion. Rapid cessation of TPN may not lead to hypoglycemia; however, tapering the infusion over 2 to 4 hours is recommended. Slow advancement of the rate of TPN (25 mL/hr) to the goal rate allows pancreatic adjustment to the dextrose load.

infarction (MI). The nurse knows that age-related changes in the cardiovascular system coupled with the MI place the patient at risk for what problem? a. Hypertension b. Heart failure c. Ventricular fibrillation d. Bradycardia ANS: b

Age-related MI is one of the most common causes of heart failure.

Age-associated changes in arterial structure and function cause large vessels to become less distensible, leading to prolonged systolic contraction, lengthened diastolic relaxation, increased myocardial oxygen demand, and diminished organ perfusion. Additionally, atherosclerotic coronary arteries may limit blood flow to the myocardium, creating a higher risk of developing myocardial ischemia or infarction.

ANS: d

Reduced drug-metabolizing capacity is caused by a decline in activity of the drug-metabolizing enzyme system, microsomal ethanol oxidizing system, and decrease in total liver blood flow. Medications that depend on the cytochrome P450 group of liver enzymes are most affected because age-associated changes cause as much as a 50% decline in enzymatic function.

the patient's skin integrity? a. There is thickening of the epidermal skin layer. b. There is a loss of sebaceous glands. c. The skin's upper layers become thin and blood flow is decreased. d. There is decreased melanocyte production.

ANS: c

Older adults are vulnerable to intrinsic and extrinsic dermatologic conditions resulting from degenerative and metabolic changes occurring throughout the skin layers. Intrinsic aging refers to the skin's natural, metabolic aging process where the skin's upper layers become thin and blood flow is decreased, which leads to a reduced ability to nourish and repair cells.

nursing intervention would be a priority? a. Encourage frequent deep breathing. b. Administer stool softeners. c. Perform neurologic checks. d. Frequently offer liquids to drink.

ANS: a

Although all the items are important, age-related changes in respiratory mechanics lead to airflow restrictions, which are reflected in decreased forced expiratory volume in 1 second (FEV1). Age-related decrease in dynamic lung volume is probably caused by decreased chest wall compliance, small airways closure during forced expiration, and decreased strength of expiratory muscles. Breathing exercises generate lung volumes of forced vital capacity, which is an untimed lung volume, and FEV1, which is a timed lung volume. These spirometry tests can assist in assessing restrictive respiratory patterns. Reduced timed lung volume is exhibited in chronic obstructive pulmonary disease, asthma, bronchiectasis, and cystic fibrosis.

b. Drug side effects experienced by the patient c. Kidney function tests d. Therapeutic drug levels ANS: b

Adverse drug effects and medication interactions may be related to pharmacokinetics or the manner in which the body absorbs, distributes, metabolizes, and excretes a drug. The aging process is associated with changes in gastric acid secretion, which can alter ionization or solubility of a drug and hence its absorption. Medication distribution depends on body composition and on physiochemical drug properties. With advancing age, a patient's fat content increases, lean body mass decreases, and total body water decreases, which can alter drug disposition.

nervous system b. An unpleasant experience accompanied by moaning, crying, and tachycardia c. Activation of the sympathetic nervous system from an injury d. Whatever the patient says it is, occurring when that patient says it does ANS: d

Pain is described as an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage. This definition emphasizes the subjective and multidimensional nature of pain. More specifically, the subjective characteristic implies that pain is whatever the person experiencing it says it is and that it exists whenever he or she says it does.

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

refers to mechanical (e.g., surgical incision), thermal (e.g., burn), or chemical (e.g., toxic substance) stimuli that damage tissues. As a result of transduction, an action potential is produced and is transmitted by nociceptive nerve fibers in the spinal cord that reach higher centers of the brain. This is called transmission, and it represents the second process of nociception. Pain sensation transmitted by the NS pathway reaches the thalamus, and the pain sensation transmitted by the PS pathway reaches brainstem, hypothalamus, and thalamus. These parts of the CNS contribute to the initial perception of pain.

instability and an allergy to morphine. The nurse anticipates that the practitioner will order which medication for severe pain? a. Hydromorphone b. Codeine c. Fentanyl d. Methadone ANS: c

Fentanyl is a synthetic opioid preferred for critically ill patients with hemodynamic instability or morphine allergy. Hydromorphone is a semisynthetic opioid that has an onset of action and a duration similar to those of morphine. It is more potent than morphine. Hydromorphone produces an inactive metabolite (i.e., hydromorphone-3-glucuronide), making it the opioid of choice for use in patients with end-stage renal disease. Codeine has limited use in the management of severe pain. It is rarely used in critical care units. It provides analgesia for mild to moderate pain. It is usually compounded with a nonopioid. Methadone is a synthetic opioid with morphine-like properties but less sedation. It is longer acting than morphine and has a long half-life. This makes it difficult to titrate in the critical care patient.

b. It focuses on the objective component of the assessment. c. It provides consistency of assessment and management. d. It provides a way to interpret physiologic indicators.

ANS: c

Many critical care units use a specific pain intensity scale because a single tool provides consistency of assessment, management, and documentation. A pain intensity scale is useful in the critical care environment. Asking the patient to grade his or her pain on a scale of 0 to 10 is a consistent method and aids the nurse in objectifying the subjective nature of the patient's pain. However, the patient's tool preference should be considered.

Although no universal definition of respiratory depression exists, it is usually described in terms of decreased respiratory rate (fewer than 8 or 10 breaths/min), decreased SpO2 levels, or elevated ETCO2 levels. A change in the patient's level of consciousness is a warning sign. It can be a sign of respiratory depression associated with airway obstruction by the tongue, leading to hypoxemia and possibly to cardiorespiratory arrest.

Based on this statement, the nurse suspects that the patient has developed what problem? a. Addiction b. Tolerance c. Physical dependence d. Physical withdrawal ANS: b

The patient has developed a tolerance to the medication. Tolerance is defined as a diminution of opioid effects over time. Addiction is defined by a pattern of compulsive drug use that is characterized by an incessant longing for an opioid and the need to use it for effects other than pain relief. Physical dependence to opioids may develop if the medication is given over a long period. Physical dependence is manifested by withdrawal symptoms when the opioid is abruptly stopped.

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

a. "The method allows the patient to act preemptively by administering a

bolus of medication when pain begins." b. "This method allows the patient to choose between an opioid and a nonopioid medication to control pain." c. "This method decreases the risk of respiratory depression and other side effects." d. "This method allows for the rise and fall of the blood level of the opioid."

ANS: a

The patient can self-administer a bolus of medication the moment the pain begins, acting preemptively. Allowing the patient to self-administer opioid doses does not diminish the role of the critical care nurse in pain management. The nurse advises about necessary changes to the prescription and continues to monitor the effects of the medication and doses. The patient is closely monitored during the first 2 hours of therapy and after every change in the prescription. If the patient's pain does not respond within the first 2 hours of therapy, a total reassessment of the pain state is essential. If the patient is pressing the button to bolus medication more often than the prescription, the dose may be insufficient to maintain pain control. Naloxone must be readily available to reverse adverse opiate respiratory effects.

deep breaths. c. Repeat it as early as 5 minutes after the first dose if warranted. d. Mix 0.4 mg of naloxone with 5 mL normal saline.

ANS: b

Critical respiratory depression can be readily reversed with administration of the opioid antagonist naloxone. The usual dose is 0.4 mg, which is mixed with 10 mL of normal saline (for a concentration of 0.04 mg/mL). Naloxone is normally given intravenously very slowly (0.5 mL over 2 minutes) while the patient is carefully monitored for reversal of the respiratory signs. Naloxone administration can be discontinued as soon as the patient is responsive to physical stimulation and able to take deep breaths. However, the medication should be kept nearby. Because the duration of naloxone is shorter than most opioids, another dose may be needed 30 minutes after the first dose.

treatment. Because pain is recognized as a subjective experience, the patient's self-report is considered the most valid measure for pain and should be obtained as often as possible. Unfortunately, in critical care, many factors, such as the administration of sedative agents, the use of mechanical ventilation, and altered levels of consciousness, may impact communication with patients. These obstacles make pain assessment more complex. Meperidine (Demerol) is a less potent opioid with agonist effects similar to those of morphine. It is considered the weakest of the opioids, and it must be administered in large doses to be equivalent in action to morphine. Because the duration of action is short, dosing is frequent. Equianalgesic means approximately the same pain relief. Dosages in the equianalgesic chart for moderate to severe pain are not necessarily starting doses. The doses suggest a ratio for comparing the analgesia of one medication with another.

b. Hypoxemia c. Hypocalcemia d. Sedation withdrawal ANS: a

Delirium is represented by a global impairment of cognitive processes, usually of sudden onset, coupled with disorientation, impaired short-term memory, altered sensory perceptions (hallucinations), abnormal thought processes, and inappropriate behavior. There is no evidence provided that would indicate the patient is hypoxemic, hypocalcemic, or going through sedation withdrawal.

mechanical ventilation. The patient suddenly becomes confused, seeing nonexistent animals in the room and pulling at the bedding. What parameter should be monitored while the patient is haloperidol? a. Sedation level b. QTc-interval c. Oxygen saturation level d. Brain waves ANS: b

ECG monitoring is recommended because haloperidol use can produce dose-dependent QTc-interval prolongation, with an increased incidence of ventricular dysrhythmias. Brain wave monitoring is indicated for deep sedation use. The patient is no longer requiring sedation so sedation monitoring may not be necessary.

13. Which medication has a greater advantage for treatment of alcohol

withdrawal syndrome (AWS) because of its longer half-life and high lipid solubility? a. Lorazepam b. Midazolam c. Propofol d. Diazepam ANS: d

Management of alcohol withdrawal involves close monitoring of AWS-related agitation and administration of IV benzodiazepines, generally diazepam (Valium) or lorazepam (Ativan). Diazepam has the advantage of a longer half-life and high lipid solubility. Lipid-soluble medications quickly cross the blood–brain barrier and enter the central nervous system to rapidly produce a sedative effect. Midazolam is the recommended drug for use in alleviating acute agitation but is known to cause seizures with AWS because of rapid withdrawal. Propofol is indicated for sedation use.

incidence of delirium? a. Restriction of visitors b. Early nutritional support c. Clustering of nursing care activities d. Bed rest ANS: c

As lack of sleep is a major contributor to the development of delirium, interventions to promote sleep should help decrease the incidence of delirium. Some critical care units have initiated sleep protocols to increase the opportunity for patients to sleep at night, dimming lights at night, ensuring there are periods of time when tubes are not manipulated and clustering nursing care interventions to provide some uninterrupted rest periods. Early ambulation is also appropriate.

beats/min, idioventricular rhythm; blood pressure is 60/32 mm Hg; SpO2 is 90%; and respiratory rate is 14 breaths/min. Which intervention should the nurse do first? a. Notify the physician and hang normal saline wide open. b. Notify the physician and obtain the defibrillator. c. Notify the physician and obtain a temporary pacemaker. d. Notify the physician and obtain a 12-lead ECG. ANS: c

If the sinus node and the atrioventricular (AV) junction fail, the ventricles depolarize at their own intrinsic rate of 20 to 40 times/min.

This is called an idioventricular rhythm and is naturally protective mechanism. Rather than trying to abolish the ventricular beats, the aim of treatment is to increase the effective heart rate (HR) and reestablish dominance of a higher pacing site such as the sinus node or the AV junction. Usually, a temporary pacemaker is used to increase the HR until the underlying problems that caused failure of the other pacing sites can be resolved.

interval until ultimately the final P wave in the group fails to conduct? a. First-degree AV block b. Second-degree AV block, type II c. Second-degree AV block, type I d. Third-degree AV block ANS: c

In Mobitz type I block, the atrioventricular (AV) conduction times progressively lengthen until a P wave is not conducted. This typically occurs in a pattern of grouped beats and is observed on the electrocardiogram (ECG) by a gradually lengthening PR interval until ultimately the final P wave in the group fails to conduct. When all atrial impulses are conducted to the ventricles but the PR interval is greater than 0.20 seconds, a condition known as first-degree AV block exists.

Mobitz type II block is always anatomically located below the AV node in the bundle of His in the bundle branches or even in the Purkinje fibers. This results in an all-or-nothing situation with respect to AV conduction. Sinus P waves are or are not conducted. When conduction does occur, all PR intervals are the same. Because of the anatomic location of the block, on the surface, ECG the PR interval is constant and the QRS complexes are wide.

development of CAD? a. Total cholesterol level of 170 mg/dL b. HDL cholesterol level of 60 mg/dL c. Triglyceride level of 120 mg/dL d. LDL cholesterol level of 190 mg/dL ANS: d

Low-density lipoprotein (LDL) cholesterol is usually described as the "bad cholesterol" because high levels are associated with an increased risk of acute coronary syndrome (ACS), stroke, and peripheral arterial disease (PAD). High LDL levels initiate the atherosclerotic process by infiltrating the vessel wall and binding to the matrix of cells beneath the endothelium. Total cholesterol levels below 200 are considered normal.

High-density lipoprotein (HDL) cholesterol levels greater 40 are at low risk of coronary artery disease. Triglyceride levels below 150 are Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

pain. The patient is suddenly awakened with severe chest pain. Three nitroglycerin sublingual tablets are administered 5 minutes apart without relief. A 12-lead electrocardiograph (ECG) reveals nonspecific ST segment elevation. The nurse suspects the patient may have which disorder? a. Silent ischemia b. Stable angina c. Unstable angina d. Prinzmetal angina ANS: c

Unstable angina usually is more intense than stable angina, may awaken the person from sleep, or may necessitate more than nitrates for pain relief. A change in the level or frequency of symptoms requires immediate medical evaluation. Severe angina that persists for more than 5 minutes, worsens in intensity, and is not relieved by one nitroglycerin tablet is a medical emergency. Stable angina is predictable and caused by similar precipitating factors each time; typically, it is exercise induced. Pain control should be achieved within 5 minutes of rest and by taking sublingual nitroglycerin. Silent ischemia describes a situation in which objective evidence of ischemia is observed on an electrocardiographic monitor but the person does not complain of anginal symptoms. Variant unstable angina, or Prinzmetal angina, is caused by a dynamic obstruction from intense vasoconstriction of a coronary artery. Spasm can occur with or without atherosclerotic lesions.

9. Which mechanism is responsible for the augmentation of coronary

arterial blood flow and increased myocardial oxygen supply seen with the intra-aortic balloon pump? a. The vacuum created in the aorta as a result of balloon deflation b. Diastolic inflation with retrograde perfusion c. Forward flow to the peripheral circulation d. Inflation during systole to augment blood pressure ANS: b

The blood volume in the aorta below the level of the balloon is propelled forward toward the peripheral vascular system, which may enhance renal perfusion. Subsequently, the deflation of the balloon just before the opening of the aortic valve creates a potential space or vacuum in the aorta, toward which blood flows unimpeded during ventricular ejection.

This decreased resistance to left ventricular ejection, or decreased afterload, facilitates ventricular emptying and reduces myocardial oxygen demands.

One complication of intra-aortic balloon support is lower extremity ischemia resulting from occlusion of the femoral artery by the catheter itself or by emboli caused by thrombus formation on the balloon.

Although ischemic complications have decreased with sheathless insertion techniques and the introduction of smaller balloon catheters, evaluation of peripheral circulation remains an important nursing assessment. The presence and quality of peripheral pulses distal to the catheter insertion site are assessed frequently along with color, temperature, and capillary refill of the involved extremity. Signs of diminished perfusion must be reported immediately.

At low dosages of 1 to 2 mcg/kg/min, dopamine stimulates dopaminergic receptors, causing renal and mesenteric vasodilation.

Moderate dosages result in stimulation of beta1 receptors to increase myocardial contractility and improve cardiac output. At dosages greater than 10 mg/kg/min, dopamine predominantly stimulates alpha receptors, resulting in vasoconstriction that often negates both the beta-adrenergic and dopaminergic effects.

a. Direct arterial vasodilation. b. Block the conversion of angiotensin I to angiotensin II. c. Increase fluid excretion at the loop of Henle. d. Peripheral vasoconstriction and central vasodilation.

ANS: b

Enalapril is an angiotensin-converting enzyme (ACE) inhibitors which produces vasodilation by blocking the conversion of angiotensin I to angiotensin II. Because angiotensin is a potent vasoconstrictor, limiting its production decreases peripheral vascular resistance. In contrast to the direct vasodilators and nifedipine, ACE inhibitors do not cause reflex tachycardia or induce sodium and water retention.

Pacing artifact; the pacemaker is sensing and capturing c. Electrical artifact; the pacemaker is not sensing d. Patient movement; check electrodes ANS: b

The pacing artifact is the spike that is seen on the electrocardiographic tracing as the pacing stimulus is delivered to the heart. A P wave is visible after the pacing artifact if the atrium is being paced. Similarly, a QRS complex follows a ventricular pacing artifact. With dual-chamber pacing, a pacing artifact precedes both the P wave and the QRS complex.

cardiac care patients? a. They cause vasoconstriction of the smooth muscles. b. They cause vasodilation of the smooth muscles. c. They increase afterload. d. They decrease preload.

ANS: c

Vasopressors are not widely used in the treatment of critically ill cardiac patients because the dramatic increase in afterload is taxing to a damaged heart. Vasopressin, also known as antidiuretic hormone, has become popular in the critical care setting for its vasoconstrictive effects. At higher doses, vasopressin directly stimulates V1 receptors in vascular smooth muscle, resulting in vasoconstriction of capillaries and small arterioles.

endocarditis are the most devastating infectious complications, but leg wound infections, pneumonia, and urinary tract infections also can occur. A potentially lethal complication, cardiac tamponade may occur after surgery if blood accumulates in the mediastinal space, impairing the heart's ability to pump. Signs of tamponade include elevated and equalized filling pressures (e.g., central venous pressure, pulmonary artery diastolic pressure, pulmonary artery occlusion pressure), decreased cardiac output, decreased blood pressure, jugular venous distention, pulsus paradoxus, muffled heart sounds, sudden cessation of chest tube drainage, and a widened cardiac silhouette on radiographs.

The risk of delirium is increased in cardiac surgery patients, especially elderly patients, and is associated with increased mortality rates and reduced quality of life and cognitive function. Nursing staff can play a critical role in the prevention and recognition of delirium.

a. Undersensing from a pacemaker b. Oversensing from a pacemaker c. ICD firing caused by VF d. Atrial pacing failure to capture ANS: a

Undersensing is the inability of the pacemaker to sense spontaneous myocardial depolarizations. Undersensing results in competition between paced complexes and the heart's intrinsic rhythm. This malfunction is manifested on the electrocardiogram by pacing artifacts that occur after or are unrelated to spontaneous complexes. Oversensing occurs as a result of inappropriate sensing of extraneous electrical signals that leads to unnecessary triggering or inhibition of stimulus Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D.

output, depending on the pacer mode. The source of these electrical signals can range from tall, peaked T waves to external electromagmetic interference in the critical care environment. The implantable cardioverter defibrillator system consists of leads and a generator and is similar to a pacemaker but with some key differences. The leads contain not only electrodes for sensing and pacing but also integrated defibrillator coils capable of delivering a shock. If the pacing stimulus fires but fails to initiate a myocardial depolarization, a pacing artifact will be present but will not be followed by the expected P wave.

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

b. Enoxaparin c. Bivalirudin d. Argatroban ANS: b

Enoxaparin (Lovenox) enhances activity of antithrombin III, a more predictable response than heparin, because enoxaparin is not largely bound to protein. There is no need for activated partial thromboplastin time (aPTT) or ACT monitoring, and there is a lower risk of heparin-induced thrombocytopenia (HIT) than with unfractionated heparin (UFH). Heparin sodium enhances activity of antithrombin III, a natural anticoagulant, to prevent clot formation. The effectiveness of treatment may be monitored by aPTT or ACT. Response is variable because of binding with plasma proteins effects may be reversed with protamine sulfate. Bivalirudin (Angiomax) directly inhibits thrombin. It may be administered alone or in combination with glycoprotein IIb/IIIa inhibitors and produces a dose-dependent increase in aPTT and ACT. It may be used instead of UFH for patients with HIT. Argatroban (Argatroban) directly inhibits thrombin. It may be used instead of UFH for patients with HIT.

15. On admission, a patient presents with a respiratory rate of 24

breaths/min, pursed-lip breathing, heart rate of 96 beats/min in sinus tachycardia, and a blood pressure of 110/68 mm Hg. The patient's arterial blood gas (ABG) values on room air are PaO2, 70 mm Hg; pH, 7.38; PaCO2, 52 mm Hg; and HCO3–, 34 mEq/L. Which diagnoses would be most consistent with the above arterial blood gas values? a. Acute pulmonary embolism b. Acute myocardial infarction c. Acute heart failure d. Chronic obstructive pulmonary disease ANS: d

The fact that the HCO3– level has increased enough to compensate for the increased pCO2 level indicates that this is not an acute condition because the kidneys can take several days to adjust. The other choices would present with a lower HCO3– level. The values indicate respiratory acidosis, and one of the potential causes is chronic obstructive pulmonary disease. Potential causes for respiratory alkalosis are pulmonary embolism, acute myocardial infarction, and acute heart failure.

bronchodilator? a. Excessive secretions b. Bronchospasms c. Thick secretions d. Fighting the ventilator ANS: b

Bronchodilators aid in smooth muscle relaxation and are of particular benefit to patients with airflow limitations. Bronchospasms are a form of airflow limitation. The patient with excessive secretions requires suctioning. The patient with thick secretions requires increased hydration. The patient fighting the ventilator needs further assessment and possibly an anxiolytic or sedative.

5. Which nursing intervention should be used to optimize oxygenation

and ventilation in the patient with acute lung failure? a. Provide adequate rest time between procedures. b. Position the patient with the good lung up. c. Suction the patient every hour. d. Avoid preoxygenating the patient before suctioning.

ANS: a

Providing adequate rest and recovery time between various procedures prevents desaturation and optimizes oxygenation. In acute lung failure, the goal of positioning is to place the least affected area of the patient's lung in the most dependent position. Patients with unilateral lung disease should be positioned with the healthy lung in a dependent position.

Preoxygenate the patient before suctioning and suction the patient only as needed.

indicative of the patient's current condition? a. Elevated pH and decreased PaCO2 b. Elevated pH and elevated PaCO2 c. Decreased pH and decreased PaCO2 d. Decreased pH and elevated PaCO2 ANS: d

Arterial blood gas analysis reveals a low PaO2 despite increases in supplemental oxygen administration (refractory hypoxemia). Initially, the PaCO2 is low as a result of hyperventilation, but eventually the PaCO2 increases as the patient fatigues. The pH is high initially but decreases as respiratory acidosis develops.

Radiologic evidence of bibasilar atelectasis b. PaO2/FiO2 ratio of 220 mm Hg c. Pulmonary artery occlusion pressure greater than 18 mm Hg d. Oxygen saturation of 92% ANS: b

According to the definition, ARDS is characterized by: • Lung injury of acute onset, within 1 week of an apparent clinical insult and with progression of respiratory symptoms • Bilateral opacities on chest imaging (chest radiograph or CT) not explained by other lung pathology (e.g. effusion, lobar/lung collapse, or nodules) • Respiratory failure not explained by heart failure or volume overload Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

• Decreased PaO2/FiO2 ratio (mild: 201 to 300 mmHg, moderate: 101 to 200 mmHg; severe ARDS: ≤ 100 mmHg) • Note that the Berlin definition requires a minimum positive end expiratory pressure (PEEP) of 5 cm H2O for consideration of the PaO2/FiO2 ratio.

Increasing the FiO2 on the ventilator c. Administering positive-end expiratory pressure (PEEP) d. Restricting fluids to 500 mL per shift ANS: c

The purpose of using positive-end expiratory pressure (PEEP) in a patient with acute respiratory distress syndrome is to improve oxygenation while reducing FiO2 to less toxic levels. PEEP has several positive effects on the lungs, including opening collapsed alveoli, stabilizing flooded alveoli, and increasing functional residual capacity.

Thus, PEEP decreases intrapulmonary shunting and increases compliance.

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

a. Reverse Trendelenburg b. Supine c. On the left side d. On the right side ANS: d

Patients with unilateral lung disease should be positioned with the healthy lung in a dependent position. Because gravity normally facilitates preferential ventilation and perfusion to the dependent areas of the lungs, the best gas exchange would take place in the dependent areas of the lungs. Thus, the goal of positioning is to place the least affected area of the patient's lung in the most dependent position.

Which pathophysiologic hemodynamic consequence should the nurse anticipate the patient may develop? a. Increased systemic vascular resistance leading to left heart failure b. Pulmonary hypertension leading to right heart failure c. Portal vein blockage leading to ascites d. Embolism to the internal carotids leading to a stroke ANS: b

The major hemodynamic consequence of a pulmonary embolus is the development of pulmonary hypertension, which is part of the effect of a mechanical obstruction when more than 50% of the vascular bed is occluded. In addition, the mediators released at the injury site and the development of hypoxia cause pulmonary vasoconstriction, which further exacerbates pulmonary hypertension.

(Select all that apply.) a. SIMV with CPAP b. SIMV with PSV c. CPAP with PSV d. T-piece and PSV e. PEEP with CPAP ANS: a,b,c,d

A variety of weaning methods are available, but no one method has consistently proven to be superior to the others. These methods include T-tube (T-piece), continuous positive airway pressure (CPAP), pressure support ventilation (PSV), and synchronized intermittent mandatory ventilation (SIMV). One recent multicenter study lends evidence to support the use of PSV for weaning over T-tube or SIMV weaning.

Often these weaning methods are used in combination with each other, such as SIMV with PSV, CPAP with PSV, or SIMV with CPAP.

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

education is needed? a. "The cuff should be deflated every hour to minimize pressure on the

trachea." b. "A small leak should be heard on inspiration if the cuff has been inflated using the minimal leak technique." c. "Cuff pressures should be kept between 20 and 30 cm H2O." d. "Cuff pressure monitoring should be done once every 24 hours."

ANS: c

Cuff pressures are monitored at a minimum of every shift and are maintained within 20 to 30 cm H2O because greater pressures decrease blood flow to the capillaries in the tracheal wall and lesser pressures increase the risk of aspiration. Pressures greater than 30 cm H2O should be reported to the practitioner. Cuffs are not routinely deflated because this increases the risk of aspiration.

Which device should the nurse anticipate an order for? a. Nasal cannula b. Simple face mask c. Reservoir cannula d. Air-entrainment nebulizer ANS: a

A low-flow oxygen delivery system provides supplemental oxygen directly into the patient's airway at a flow of 8 L/min or less. Because this flow is insufficient to meet the patient's inspiratory volume requirements, it results in a variable FiO2 as the supplemental oxygen is mixed with room air.

Confirmation of the diagnosis of ischemic stroke is the first step in the emergent evaluation of these patients. Differentiation from intracranial hemorrhage is vital. Noncontrast computed tomography (CT) scanning is the method of choice for this purpose, and it is considered the most important initial diagnostic study. Magnetic resonance imaging (MRI) can demonstrate infarction of cerebral tissue earlier than can CT but is less useful in the emergent differential diagnosis.

includes which intervention? a. Placing the patient in the Trendelenburg position b. Administering an antihypertensive agent c. Initiating hemodynamic augmentation therapy d. Intubating and ventilating the patient ANS: d

Intracerebral hemorrhage is a medical emergency. Initial management requires attention to airway, breathing, and circulation. Intubation is usually necessary. Blood pressure management must be based on individual factors. Reduction in blood pressure is usually necessary to decrease ongoing bleeding, but lowering blood pressure too much or too rapidly may compromise cerebral perfusion pressure, especially in a patient with elevated intracranial pressure. National guidelines recommend keeping the mean arterial blood pressure below 130 mm Hg in patients with a history of hypertension by moderate blood pressure reduction to a mean arterial pressure below 110 mm Hg.

focal deficits for several days. The initial noncontract CT findings are negative. The patient is being prepared for a lumbar puncture. Which CSF appearance finding should the nurse expect? a. Cloudy b. Bloody c. Xanthochromic d. Clear ANS: b

If the initial computed tomography findings are negative, a lumbar puncture is performed to obtain cerebrospinal fluid (CSF) for analysis.

CSF after subarachnoid hemorrhage (SAH) appears bloody and has a red blood cell count greater than 1000 cells/mm3. If the lumbar puncture is performed more than 5 days after the SAH, the CSF fluid is xanthochromic (dark amber) because the blood products have broken down. Cloudy CSF usually indicates some type of infectious process such as bacterial meningitis, not SAH.

c. Resolving cerebral d. Excessive dehydration ANS: b

Herniation of intracerebral contents results in the shifting of tissue from one compartment of the brain to another and places pressure on cerebral vessels and vital function centers of the brain. If unchecked, herniation rapidly causes death as a result of the cessation of cerebral blood flow and respirations. Signs of brain herniation include fixed and dilated pupils, flaccidity, and respiratory arrest. The intracranial pressure drops as the pressure is relieved by shifting the intracranial components downward.

Intravenous pyelography (IVP) c. Renal ultrasonography (ECHO) d. Renal angiography ANS: b

Intravenous pyelography allows visualization of the internal kidney parenchyma, calyces, pelvis, ureters, and bladder.

Kidney–ureter–bladder flat-plate radiography of the abdomen determines the position, size, and structure of the kidneys, urinary tract, and pelvis. It is useful for evaluating the presence of calculi and masses and is usually followed by additional tests. In ultrasonography, Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

high-frequency sound waves are transmitted to the kidneys and urinary tract, and the image is viewed on an oscilloscope. This noninvasive procedure identifies fluid accumulation or obstruction, cysts, stones or calculi, and masses. It is useful for evaluating the kidneys before biopsy.

Angiography is injection of contrast into arterial blood perfusing the kidneys. It allows for visualization of renal blood flow and may also visualize stenosis, cysts, clots, trauma, and infarctions.

expect to see elevated values in which laboratory results? (Select all that apply.) a. Blood urea nitrogen (BUN) b. Creatinine c. Glucose d. Hemoglobin and hematocrit e. Protein ANS: a,b,d

With kidney dysfunction, the blood urea nitrogen (BUN) is elevated because of a decrease in the glomerular filtration rate and resulting decrease in urea excretion. Elevations in the BUN can be correlated with the clinical manifestations of uremia; as the BUN rises, symptoms of uremia become more pronounced. Creatinine levels are fairly constant and are affected by fewer factors than BUN. As a result, the serum creatinine level is a more sensitive and specific indicator of kidney function than BUN. Creatinine excess occurs most often in persons with acute kidney injury resulting from impaired excretion. Decreased hematocrit value can indicate fluid volume excess because of the Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

a. Ultrafiltration b. Hemodialysis c. Reverse osmosis d. Colloid extraction ANS: a

To remove fluid, a positive hydrostatic pressure is applied to the blood, and a negative hydrostatic pressure is applied to the dialysate bath. The two forces together, called transmembrane pressure, pull and squeeze the excess fluid from the blood. The difference between the two values (expressed in millimeters of mercury [mm Hg]) represents the transmembrane pressure and results in fluid extraction, known as ultrafiltration, from the vascular space.

The fluid that is removed each hour is not called urine; it is known as ultrafiltrate. Typically, some of the ultrafiltrate is replaced through the continuous renal replacement therapy circuit by a sterile replacement fluid. Diffusion is the movement of solutes along a concentration gradient from a high concentration to a low concentration across a semipermeable membrane. Convection occurs when a pressure gradient is set up so that the water is pushed or pumped across the dialysis filter and carries the solutes from the bloodstream with it.

esophagogastric varices. The nurse knows that varices are caused by which pathophysiologic mechanism? a. Portal hypertension b. Superficial mucosal erosions c. Breakdown the mucosal resistance d. Inflammation and ulceration ANS: a

Esophagogastric varices are engorged and distended blood vessels of the esophagus and proximal stomach that develop as a result of portal hypertension secondary to hepatic cirrhosis, a chronic disease of the liver that results in damage to the liver sinusoids. Without adequate sinusoid function, resistance to portal blood flow is increased, and pressures within the liver are elevated. This leads to a rise in portal Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

ANS: c

Bariatric procedures are divided into three broad types: (1) restrictive, (2) malabsorptive, and (3) combined restrictive and malabsorptive. The Roux-en-Y gastric bypass combines both strategies by creating a small gastric pouch and anastomosing the jejunum to the pouch. Food then bypasses the lower stomach and duodenum, resulting in decreased absorption of digestive materials. The standard operation for pancreatic cancer is a pancreaticoduodenectomy, also called the Whipple Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M.

ANS: b,d,e

The patient may experience a variety of other complications, including cerebral edema, cardiac dysrhythmias, acute respiratory failure, sepsis, and acute kidney injury. Cerebral edema and increased intracranial pressure develop as a result of breakdown of the blood–brain barrier and astrocyte swelling. Circulatory failure that mimics sepsis is common in acute liver failure and may exacerbate low cerebral perfusion pressure.

Hypoxemia, acidosis, electrolyte imbalances, and cerebral edema can precipitate the development of cardiac dysrhythmias. Acute respiratory failure, progressing to acute respiratory distress syndrome, intrapulmonary shunting, ventilation-perfusion mismatch, sepsis, and aspiration may be attributed to the universal arterial hypoxemia.

The antidiuretic hormone test is used to differentiate between neurogenic diabetes insipidus (DI) (central) and nephrogenic (kidney) DI. In severe central DI, in which the pituitary is affected, the urine osmolality shows a significant increase (becomes more concentrated), which indicates that the cell receptor sites on the kidney tubules are responsive to vasopressin. Test results in which urine osmolality remains unchanged indicate nephrogenic DI, suggesting kidney dysfunction because the kidneys are no longer responsive to ADH.

membrane c. Associated with a permanent loss of consciousness d. Signs and symptoms include bilateral pupil dilation ANS: a

Epidural hematoma (EDH) is a collection of blood between the inner table of the skull and the outermost layer of the dura. EDHs are most often associated with skull fractures and middle meningeal artery lacerations (two-thirds of patients). The classic clinical manifestations of EDH include brief loss of consciousness followed by a period of lucidity. Rapid deterioration in the level of consciousness should be anticipated, because arterial bleeding into the epidural space can occur quickly. The patient may complain of a severe, localized headache and may be sleepy. A dilated and fixed pupil on the same side as the impact area is a hallmark of EDH.

secondary to a motor vehicle crash. The patient's plan of care would involve which nursing action? a. Perform neurologic assessments once a shift. b. Obtain a computed tomography (CT) scan every day. c. Monitor blood pressure and temperature every hour. d. Initiate warming measures to keep temperature greater than 37.5°C. ANS: c

Severe DAI usually manifests as a prolonged, deep coma with periods of hypertension, hyperthermia, and excessive diaphoresis. Treatment of DAI includes support of vital functions. Neurologic assessment is performed every hour. DAI may not be visible on CT scan. Warming measures are generally not needed but cooling measure may be needed.

move his legs better than he can move his arms. The nurse suspects the patient may have which type of injury? a. Posterior cord syndrome b. Brown- Séquard syndrome c. Diffuse axonal injury d. Central cord syndrome ANS: d

Central cord syndrome is associated with cervical hyperextension/flexion injury and hematoma formation in the center of the cervical cord. This injury produces a motor and sensory deficit more Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

pronounced in the upper extremities than in the lower extremities.

Posterior cord syndrome is associated with cervical hyperextension injury with damage to the posterior column. This results in the loss of position sense, pressure, and vibration below the level of injury.

Brown-Séquard syndrome is associated with damage to only one side of the cord. This produces loss of voluntary motor movement on the same side as the injury, with loss of pain, temperature, and sensation on the opposite side. Diffuse axonal injury (DAI) is a term used to describe prolonged posttraumatic coma that is not caused by a mass lesion, although DAI with mass lesions has been reported.

6. A patient has been admitted with a flail chest. What findings would

the nurse expect to observe supporting this diagnosis? a. Tracheal deviation toward the unaffected side b. Jugular venous distention c. Paradoxical respiratory movement d. Respiratory alkalosis ANS: c

Tracheal deviation and jugular venous distention are findings associated with tension pneumothorax. Respiratory acidosis is usually present because of the ineffective breathing pattern. In a flail chest, a free-floating segment of the chest wall moves independently from the rest of the thorax and results in paradoxical chest wall movement during the respiratory cycle. During inspiration, the intact portion of the chest wall expands while the injured part is sucked in. During expiration, the chest wall moves in, and the flail segment moves out.

finding will cause a nurse to suspect that the patient's condition is deteriorating? a. Increased bruising on the chest wall b. Increased need for pain medication c. The development of respiratory alkalosis d. Increased work of breathing ANS: d

A contusion manifests initially as a hemorrhage followed by alveolar and interstitial edema. Patients with severe contusions may continue to show decompensation, such as respiratory acidosis and increased work of breathing, despite aggressive nursing management. Increased bruising and the need for pain medication are not signs of deterioration.

Monitor serial biomarkers for evidence of further damage. d. Do not administer antidysrhythmic medications as they are

ineffective.

ANS: b

The patient should be monitored for new onset of dysrhythmias. The patient may complain of chest pain that is similar to anginal pain, but it is not typically relieved with nitroglycerin. Chest pain is usually caused by associated injuries. Use of biomarkers, such as troponin, offers very little diagnostic help for BCI. Medical management is aimed at preventing and treating complications. This approach includes hemodynamic monitoring in a critical care unit and possible administration of antidysrhythmic medications.

a. Emergency surgery b. Diagnostic peritoneal lavage (DPL) c. Computed tomography scan d. Intra-abdominal pressure monitoring ANS: a

Hemodynamically unstable patients with a positive FAST scan generally undergo emergency surgery to achieve hemostasis. Diagnostic peritoneal lavage (DPL) is undertaken less frequently in many trauma centers. CT scanning is the mainstay of diagnostic evaluation in the hemodynamically stable patient with abdominal trauma; however, when the patient is hemodynamically unstable, the patient is taken to surgery.

Intra-abdominal pressure monitoring is done in the presence of intra-abdominal hypertension.

The patient's vital signs include: BP-92/66 mm Hg; HR-118 beats/min; T-38.7°C; and CVP-5 mm Hg. What is the most likely cause of this hemodynamic picture? a. Septic shock b. Hemorrhagic shock c. Cardiogenic shock d. Neurogenic shock ANS: a

The patient with multiple injuries is at risk for overwhelming infections and sepsis. The source of sepsis in the trauma patient can be invasive therapeutic and diagnostic catheters or wound contamination with exogenous or endogenous bacteria. The source of the septic nidus must be promptly evaluated. Gram stain and cultures of blood, urine, sputum, invasive catheters, and wounds are obtained.

physiologic change? a. Deterioration of cerebral and motor skills b. Poor vision and hearing c. Diminished pain perception d. Limited physiologic reserve ANS: d

Older adults have limited ability to increase their heart rate in response to blood loss, obscuring one of the earliest signs of hypovolemia-tachycardia. Loss of physiologic reserve and the presence of preexisting medical conditions are likely to produce further conflicting hemodynamic data. An older patient's lack of physiologic reserve makes it imperative that early nutritional support is initiated.

Older persons experience most of the falls that result in injuries, and these falls are likely to occur from level surfaces or steps. Because many of the falls may be caused by an underlying medical condition (e.g., syncope, myocardial infarction, dysrhythmias), management of an older patient who has fallen must include an evaluation of events and conditions immediately preceding the fall.

Over-resuscitation related to overestimation of the burn area involved. d. Under-resuscitation because of probable wound conversion.

ANS: d

The rate of fluid administration is adjusted according to the individual's response, which is determined by monitoring urine output, heart rate, blood pressure, and level of consciousness. Meticulous attention to the patient's intake and output is imperative to ensure that he or she is appropriately resuscitated. Under-resuscitation may result in inadequate cardiac output, leading to inadequate organ perfusion and the potential for wound conversion from a partial-thickness to full-thickness injury.

Over-resuscitation may lead to moderate to severe pulmonary edema; to excessive wound edema causing a decrease in perfusion of unburned tissue in the distal portions of the extremities; or to edema inhibiting perfusion of the zone of stasis, resulting in wound conversion.

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

c. Proliferative phase d. Maturation phase ANS: c

The proliferative phase of healing occurs approximately 4 to 20 days after injury. The key cell in this phase of healing, the fibroblast, rapidly synthesizes collagen. Collagen synthesis provides the needed strength for a healing wound. The inflammatory phase begins immediately after injury. Vascular changes and cellular activity characterize this period.

Changes in the severed vessels occur in an attempt to wall off the wound from the external environment. The maturation phase, or remodeling phase, of healing occurs from approximately 20 days after injury to longer than 1 year after injury. During this period, the wound develops tensile strength as collagen deposits form scar tissue.

Chapter_26.bnk MULTIPLE CHOICE 1. A nurse is discussing the concept of shock with a new graduate nurse.

Which statement indicates the new graduate nurse understood the information? a. Shock is a physiologic state resulting in hypotension and tachycardia. b. Shock is an acute wide spread process of inadequate tissue perfusion. c. Shock is a degenerative condition leading to organ failure and death. d. Shock is a condition occurring with hypovolemia that results in

hypotension.

ANS: b

Shock is an acute, widespread process of impaired tissue perfusion that results in cellular, metabolic, and hemodynamic alterations. It is a complex pathophysiologic process that often results in multiple organ dysfunction syndrome and death. All types of shock eventually result in ineffective tissue perfusion and the development of acute circulatory failure.

Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D. Urden, Kathleen M. Stacy, Mary E. Lough

Absolute hypovolemia occurs when there is a loss of fluid from the intravascular space. This can result from an external loss of fluid from the body or from internal shifting of fluid from the intravascular space to the extravascular space. Fluid shifts can result from a loss of intravascular integrity, increased capillary membrane permeability, or decreased colloidal osmotic pressure. Relative hypovolemia occurs when vasodilation produces an increase in vascular capacitance relative to circulating volume.

immunoglobulin E (IgE) mediated response as a result of what physiologic mechanism? a. Direct activation of mast cells and basophils b. Nonimmunologic stimulation of biochemical mediators c. Repeat exposure to an antigen in the presence of preformed IgE

antibodies d. Activation of the systemic inflammatory response ANS: c

IgE is an antibody that is formed as part of the immune response. The first time an antigen enters the body, an antibody IgE, specific for the antigen, is formed. The antigen-specific IgE antibody is then stored by attachment to mast cells and basophils. This initial contact with the antigen is known as a primary immune response. The next time the antigen enters the body, the preformed IgE antibody reacts with it, and a secondary immune response occurs.

which are metabolized into uric acid. Metabolic acidosis ensues, resulting in crystallization of the uric acid in the distal tubules of the kidneys and leading to obstruction of urine flow. Glomerular filtration rates drop as the kidneys are unable to clear the increasing amounts of uric acid. Consequently, acute kidney injury eventually occurs.

Which intervention would be incorporated into the plan of care to prevent the metabolic imbalances associated with this disorder? a. Give sodium polystyrene sulfonate for hypokalemia. b. Keep urine pH below 7.0. c. Restrict all oral fluids. d. Restrict foods containing potassium.

ANS: d

Dietary restrictions of potassium and phosphorus may be necessary. The goals in treating hyperuricemia are to inhibit uric acid formation and to increase renal clearance. These can be accomplished through the administration of sodium bicarbonate to increase the pH of the urine to above 7.0, which increases the solubility of uric acid, preventing subsequent crystallization. Administration of intravenous fluids may be necessary early in the course of treatment if inadequate hydration exists.

If potassium levels rise dangerously, Kayexalate (sodium polystyrene sulfonate) may be given orally, or if the patient is unable to tolerate oral medications because of nausea and vomiting, rectal instillation may be Test Bank for Priorities in Critical Care Nursing 8th Edition by Linda D.
