Question 1
Regular
The nurse is preparing a client for a multiple gated acquisition (MUGA) scan. What would be an important instruction for the nurse to give a client who is to undergo a MUGA scan?
Correct!
Incorrect
The correct answer is: D
Rationale
Lie very still at intermittent times during the test.
Maintaining stillness is crucial during a MUGA scan as movement can interfere with the accuracy of the images. The nurse must instruct the client to stay still to ensure optimal visualization of heart function and blood flow, leading to precise diagnostic results.
A: Avoid any activity at least 2 hours before the test. Stopping activity is not specifically emphasized for a MUGA scan, as the primary concern is remaining still during the procedure itself.
B: Drink plenty of fluids during the test. Hydration is generally important, but excessive fluid intake may not be recommended during the scan due to potential discomfort or interference with the imaging process.
C: Avoid dairy products a day before and a day after the test. There is no specific dietary restriction related to dairy for a MUGA scan, making this instruction unnecessary and irrelevant for the procedure.

Question 2
Regular
A client with left-sided heart failure is in danger of impaired renal perfusion. How would the nurse assess this client for impaired renal perfusion?
Correct!
Incorrect
The correct answer is: D
Rationale
Assess for elevated blood urea nitrogen levels. Elevated blood urea nitrogen (BUN) indicates impaired renal perfusion, as the kidneys struggle to filter waste effectively due to decreased blood flow, common in left-sided heart failure.
A: Assess for reduced urine output. Reduced urine output may suggest renal issues, but it does not specifically indicate impaired perfusion compared to elevated BUN levels.
B: Assess for reduced blood sodium levels. Low sodium levels do not directly reflect renal perfusion status and can result from various factors unrelated to heart function.
C: Assess for elevated blood potassium levels. Elevated potassium may indicate renal impairment but is not a definitive measure of perfusion issues specifically related to left-sided heart failure.

Question 3
Regular
The student nurse is caring for a client with heart failure. Diuretics have been prescribed. What method might be used with a debilitated client to help the nurse evaluate the client's response to diuretics?
Correct!
Incorrect
The correct answer is: B
Rationale
Using a urinary catheter. This method provides accurate and timely measurement of urine output, allowing the nurse to assess the diuretic's effectiveness and the client's fluid balance in heart failure management.
A: Using mechanical ventilation. This approach is not relevant for evaluating diuretic response; it focuses on respiratory support rather than monitoring fluid elimination or renal function in heart failure.
C: Using a pulmonary artery catheter. While this device can provide hemodynamic data, it is invasive and not the primary method for assessing urinary output or direct diuretic response.
D: Using a biventricular pacemaker. This intervention addresses heart rhythm issues rather than fluid management, making it unsuitable for evaluating the effectiveness of diuretic therapy in this context.

Question 4
Regular
The nurse is working in a long-term care facility with a group of older adults with cardiac disorders. Why would it be important for the nurse to closely monitor an older adult receiving digitalis preparations for cardiac disorders?
Correct!
Incorrect
The correct answer is: A
Rationale
Older adults are at increased risk for toxicity. This demographic often has altered drug metabolism and excretion, making them more susceptible to the side effects and toxicity of digitalis preparations, necessitating close monitoring.
B: Older adults are at increased risk for cardiac arrests. While older adults may face cardiac issues, this option does not directly relate to the specific risks associated with digitalis preparations.
C: Older adults are at increased risk for hyperthyroidism. Hyperthyroidism is not directly influenced by digitalis; thus, this option does not pertain to the monitoring requirements for those receiving digitalis therapy.
D: Older adults are at increased risk for asthma. Asthma is unrelated to digitalis use; this option fails to connect with the key concerns regarding toxicity and cardiac management in older adults.

Question 5
Regular
A client diagnosed with heart failure has been admitted to the ICU prior to invasive treatment. What treatment could be considered curative for this client?
Correct!
Incorrect
The correct answer is: C
Rationale
Surgical ventricular restoration is a treatment option that directly addresses the structural abnormalities of the heart caused by heart failure, potentially restoring normal function and improving the client’s prognosis significantly.
A: Cardiomyoplasty This procedure involves wrapping muscle around the heart, which may help but does not fundamentally correct the underlying heart failure condition or restore normal heart function.
B: External pacemaker placement This method aids in regulating heart rhythms but does not address the fundamental issues associated with heart failure or provide a curative effect on the heart's structure.
D: Ventricular assist device This device supports heart function temporarily and is not a permanent solution, thus failing to provide a definitive correction of the underlying causes of heart failure.

Question 6
Regular
A client with pulmonary edema has been admitted to the ICU. What would be the standard care for this client?
Correct!
Incorrect
The correct answer is: B
Rationale
Continuous monitoring of blood pressure and pulse is crucial for clients with pulmonary edema, as it helps assess cardiac function and fluid status. This standard care allows for timely interventions and adjustments in treatment based on vital signs, ensuring patient safety in the ICU setting.
A: Intubation of the airway This procedure is not a standard care for pulmonary edema unless respiratory failure occurs, which is not indicated in all cases of the condition.
C: Insertion of a central venous catheter This intervention is typically reserved for specific scenarios, such as severe heart failure or shock, rather than for routine management of pulmonary edema.
D: Hourly administration of a fluid bolus Excess fluid administration contradicts the management of pulmonary edema, where fluid overload is the primary concern, necessitating careful fluid restriction instead.

Question 7
Regular
The nurse documents pitting edema in the bilateral lower extremities of the client. What does this documentation mean?
Correct!
Incorrect
The correct answer is: A
Rationale
There is excess fluid volume in the interstitial space in areas affected by gravity.
This documentation indicates that fluid has accumulated in the spaces between cells, particularly in the lower extremities where gravity influences fluid distribution. Pitting edema signifies that the excess fluid can be displaced when pressure is applied, highlighting an underlying issue related to fluid balance in the body.
B: There is excess fluid volume in the venous system of the lower extremities. This option misinterprets the location of fluid accumulation; pitting edema specifically points to interstitial spaces rather than venous vessels.
C: There is excess fluid volume in the arterial system of the lower extremities. This choice is inaccurate as arterial systems do not exhibit pitting edema; such swelling pertains to interstitial fluid, not arterial flow.
D: There is excess fluid volume in the hepatic system. This option is unrelated; pitting edema specifically describes a condition in lower extremities, not involving the liver or its functions.

Question 8
Regular
A client with severe mitral valve insufficiency has been admitted to the unit. The client has heart failure and has developed pulmonary edema. What would be the best course of treatment for this client?
Correct!
Incorrect
The correct answer is: C
Rationale
Surgery. In cases of severe mitral valve insufficiency, surgical intervention is the most effective treatment to repair or replace the valve, thereby alleviating heart failure symptoms and pulmonary edema.
A: Cardiac glycosides. While these medications can improve heart contractility, they do not address the underlying valvular issue causing the severe heart failure and pulmonary edema.
B: Beta-blockers. Although they can manage heart rate and reduce workload, beta-blockers do not correct the structural problem of the mitral valve insufficiency and the resultant heart failure.
D: Palliative care. This approach focuses on comfort rather than treating the underlying condition, making it unsuitable for a client needing urgent surgical intervention to resolve the severe symptoms.

Question 12
Regular
A client has a myocardial infarction in the left ventricle and develops crackles bilaterally; 3-pillow orthopnea; an S3 heart sound; and a cough with pink, frothy sputum. The nurse obtains a pulse oximetry reading of 88%. What do these signs and symptoms indicate for this client?
Correct!
Incorrect
The correct answer is: B
Rationale
The development of left-sided heart failure. The signs and symptoms, including bilateral crackles, orthopnea, an S3 heart sound, and pink, frothy sputum, indicate pulmonary congestion due to impaired left ventricular function, typical of left-sided heart failure following a myocardial infarction. The low pulse oximetry reading further supports this condition due to inadequate oxygenation.
A: The development of chronic obstructive pulmonary disease (COPD) Symptoms like crackles and orthopnea suggest fluid overload, not the airflow limitation characteristic of COPD, which typically features wheezing rather than these specific signs.
C: The development of right-sided heart failure Right-sided heart failure manifests with peripheral edema and jugular venous distension, which are absent in this case, making it an unlikely diagnosis in this context.
D: The development of cor pulmonale Cor pulmonale arises from chronic lung disease leading to right heart failure, while the current symptoms point towards acute left-sided heart failure, following the myocardial infarction.

Question 13
Regular
A client is admitted to the hospital with a diagnosis of heart failure, and the health care provider prescribes a BNP level. What results would indicate to the nurse that the client is in moderate heart failure?
Correct!
Incorrect
The correct answer is: C
Rationale
C: 780 pg/mL indicates moderate heart failure as BNP levels between 300 to 900 pg/mL are typically associated with this stage, reflecting the heart's struggle to manage fluid overload effectively.
A: 120 pg/mL suggests a normal BNP level, indicating that heart failure is unlikely and the heart's function is within a healthy range.
B: 400 pg/mL indicates mild heart failure, as it falls below the threshold for moderate classification, signaling less severe cardiac strain.
D: 980 pg/mL exceeds moderate heart failure levels, suggesting severe heart failure and significant cardiovascular stress, requiring more intensive management.
Correct Answer: C

Question 14
Regular
A client in the hospital informs the nurse he 'feels like his heart is racing and can't catch his breath.' What does the nurse understand occurs as a result of a tachyarrhythmia?
Correct!
Incorrect
The correct answer is: B
Rationale
B: It reduces ventricular ejection volume. Tachyarrhythmia leads to rapid heartbeats that impair the heart's ability to fill properly during diastole, ultimately diminishing the volume of blood ejected during systole, affecting overall cardiac output.
A: It causes a loss of elasticity in the myocardium. While tachyarrhythmias can stress the heart, they do not directly result in loss of myocardial elasticity, which is more related to chronic conditions.
C: It increases afterload. Afterload refers to the resistance the heart must overcome to pump blood. Tachyarrhythmia primarily affects heart rate and filling rather than directly increasing vascular resistance.
D: It increases preload. Preload is determined by venous return to the heart. Although tachyarrhythmia affects cardiac function, it does not inherently increase preload, which depends on volume status and venous return dynamics.

Question 15
Regular
A client with heart failure is having a decrease in cardiac output. What indication does the nurse have that this is occurring?
Correct!
Incorrect
The correct answer is: C
Rationale
Decreased blood pressure, such as 80/46 mm Hg, indicates inadequate cardiac output, as the heart fails to effectively pump sufficient blood, leading to poor perfusion and potential organ dysfunction.
A: Heart rate of 72 beats/minute signifies a normal resting heart rate, which does not imply decreased cardiac output, as the heart can still function effectively at this rate.
B: Respiratory rate of 20 breaths/minute reflects a mildly elevated rate but does not directly connect to cardiac output; it may indicate anxiety or mild distress rather than heart failure.
D: Oxygen saturation of 94% indicates reasonable oxygenation, suggesting that the client is not critically hypoxic, which does not correlate with decreased cardiac output in this context.

Question 21
Regular
The nurse observes a client with an onset of heart failure having rapid, shallow breathing at a rate of 32 breaths/minute. What blood gas analysis does the nurse anticipate finding initially?
Correct!
Incorrect
The correct answer is: D
Rationale
Rapid, shallow breathing indicates hyperventilation, which leads to a decrease in carbon dioxide levels in the blood. This process often results in respiratory alkalosis, as the body expels CO2 faster than it is produced.
A: Metabolic acidosis Excessive acid accumulation in the body is not indicated by hyperventilation; instead, this condition typically presents with deep, slow breathing patterns.
B: Metabolic alkalosis While respiratory alkalosis involves decreased CO2, metabolic alkalosis relates to increased bicarbonate levels and does not directly stem from the observed rapid, shallow breathing.
C: Respiratory acidosis Shallow breathing typically causes CO2 retention, leading to acidosis, but the rapid nature of the breathing suggests CO2 is being expelled rather than retained.

Question 22
Regular
The nurse is providing discharge instructions to a client with heart failure preparing to leave the following day. What type of diet should the nurse request the dietitian to discuss with the client?
Correct!
Incorrect
The correct answer is: D
Rationale
A low-sodium diet should be requested for the client. Reducing sodium intake is crucial for individuals with heart failure as it helps to decrease fluid retention and lower blood pressure, enhancing overall heart function.
A: Low-fat diet This diet may benefit heart health but does not specifically address the fluid retention issues common in heart failure patients. Sodium reduction is more critical.
B: Low-potassium diet Limiting potassium is unnecessary for most heart failure patients unless they are on certain medications. Many require potassium to maintain proper heart function and overall health.
C: Low-cholesterol diet While beneficial for overall cardiovascular health, this diet does not directly target the fluid retention and blood pressure concerns associated with heart failure management.

Question 23
Regular
The nurse is preparing to administer digoxin to a client with heart failure. The nurse obtains an apical pulse rate for 1 minute and determines a rate of 52 beats/minute. What is the first action by the nurse?
Correct!
Incorrect
The correct answer is: B
Rationale
Withholding the medication and notifying the health care provider of the heart rate is the first action. An apical pulse of 52 beats/minute indicates bradycardia, which is a potential contraindication for digoxin administration, necessitating immediate communication with the provider for further evaluation and guidance on the patient's safety.
A: Administer the medication and inform the charge nurse about the rate. Giving digoxin without addressing bradycardia could lead to serious complications, making this choice unsafe and inappropriate.
C: Administer atropine to speed the heart rate and then administer the digoxin. Atropine usage is not standard practice in this scenario and could introduce unnecessary risk before assessing the patient's condition.
D: Administer the medications and then notify the health care provider. Prioritizing medication administration over patient safety disregards vital signs, risking adverse reactions or complications from digoxin in a bradycardic patient.

Question 24
Regular
The nurse is preparing to administer furosemide to a client with severe heart failure. What lab study should be of most concern for this client while taking furosemide?
Correct!
Incorrect
The correct answer is: D
Rationale
A potassium level of 3.1 is of most concern for this client while taking furosemide. Low potassium levels can lead to serious cardiac complications, especially in patients with heart failure, as furosemide is a diuretic that can further deplete potassium, increasing the risk of arrhythmias and other health issues.
A: BNP of 100 This level indicates mild heart failure and does not pose an immediate risk associated with furosemide administration, which primarily affects electrolyte balance rather than BNP levels.
B: Sodium level of 135 A sodium level of 135 is within a generally acceptable range for clients on furosemide, indicating no significant risk regarding sodium depletion or related complications at this level.
C: Hemoglobin of 12 This hemoglobin level falls within normal limits for adults, and while monitoring is essential, it does not indicate an immediate concern when administering furosemide.

Question 25
Regular
The nurse is administering captopril to a client with a diagnosis of heart failure. What type of medication does the nurse infer the client is taking?
Correct!
Incorrect
The correct answer is: A
Rationale
Captopril is an angiotensin converting enzyme (ACE) inhibitor, commonly prescribed to manage heart failure by relaxing blood vessels, which helps to reduce the heart's workload and improve blood flow.
B: A thiazide diuretic This option refers to a class of medications primarily used to treat hypertension and fluid retention, not specifically indicated for heart failure management like captopril.
C: An angiotensin receptor blocker (ARB) While related to heart failure treatment, ARBs function differently than ACE inhibitors, blocking angiotensin II receptors instead of inhibiting its production as captopril does.
D: A calcium channel blocker This type of medication primarily treats hypertension and certain arrhythmias by inhibiting calcium influx in cardiac and vascular smooth muscle, differing fundamentally from captopril’s mechanism.

Question 26
Regular
A client is awaiting the availability of a heart for transplant. What option may be available to the client as a bridge to transplant?
Correct!
Incorrect
The correct answer is: D
Rationale
A ventricular assist device (VAD) may be available to the client as a bridge to transplant. VADs are mechanical pumps that help circulate blood, supporting heart function until a suitable donor heart becomes available, effectively prolonging the patient's life and improving their condition while awaiting surgery.
A: Implanted cardioverter-defibrillator (ICD) provides electrical shocks to correct dangerous heart rhythms but does not assist in blood circulation, making it unsuitable as a temporary bridge.
B: Pacemaker regulates heartbeats by sending electrical signals but does not provide hemodynamic support, which is essential for patients awaiting a heart transplant.
C: Intra-aortic balloon pump (IABP) supports the heart by improving blood flow and reducing workload but is typically used for short-term stabilization rather than as a bridge to transplant.

Question 27
Regular
A client with heart failure reports not having had a bowel movement in 2 days. Why would it be important for the nurse to obtain a prescription for a stool softener?
Correct!
Incorrect
The correct answer is: A
Rationale
Straining engages the Valsalva maneuver, which can cause dangerous effects. In clients with heart failure, this maneuver increases intrathoracic pressure, potentially leading to arrhythmias or decreased cardiac output, making stool softeners crucial for safe bowel movements.
B: The client should not develop hemorrhoids. While avoiding hemorrhoids is important, it does not address the immediate risks associated with straining in heart failure patients.
C: The client can develop a rectal fissure, which will increase pain levels. Although painful, the risk of a fissure does not directly relate to the cardiovascular complications associated with straining.
D: The client should have a bowel movement every day to avoid development of an intestinal obstruction. Daily bowel movements are ideal, but the focus should be on preventing the strain that endangers heart function.

Question 28
Regular
A client diagnosed with pulmonary edema has a PaCO2 of 72 mm Hg and an oxygen saturation of 84%. What method of oxygen delivery would best meet the needs of this client?
Correct!
Incorrect
The correct answer is: A
Rationale
Intubation and mechanical ventilation would best meet the needs of this client. Given the high PaCO2 of 72 mm Hg and severely low oxygen saturation of 84%, invasive support is crucial for adequate gas exchange and respiratory stabilization in pulmonary edema.
B: Face mask with nonrebreather offers higher oxygen flow but may not sufficiently manage severe hypercapnia and hypoxemia, which require more intensive respiratory support than a nonrebreather can provide.
C: Oxygen cannula at 6 L/minute does not deliver enough oxygen to address the client’s critical hypoxemia and high carbon dioxide levels, making it inadequate for this situation.
D: Venturi mask at 35% provides controlled oxygen delivery, yet it cannot adequately address the severe respiratory failure indicated by the client's significantly elevated PaCO2 and low oxygen saturation.

Question 29
Regular
A client develops cardiogenic pulmonary edema and is extremely apprehensive. What medication can the nurse administer with a health care provider's prescription that will relieve anxiety and slow respiratory rate?
Correct!
Incorrect
The correct answer is: D
Rationale
Morphine sulfate can be administered to relieve anxiety and reduce respiratory rate in patients with cardiogenic pulmonary edema. It provides sedation and alleviates discomfort, which is crucial in managing their condition.
A: Furosemide primarily functions as a diuretic, which helps reduce fluid overload but does not address anxiety or respiratory rate effectively in this context.
B: Nitroglycerin is used to relieve chest pain and decrease cardiac workload but does not have sedative properties to manage anxiety and respiratory rate.
C: Dopamine primarily supports cardiac output and blood pressure but lacks the anxiolytic effects necessary for alleviating anxiety in this patient scenario.

Question 30
Regular
A client is taking furosemide for the treatment of heart failure. What food should the nurse suggest that is rich in potassium?
Correct!
Incorrect
The correct answer is: B
Rationale
Peanut butter. This food is a good source of potassium, which is essential for clients on furosemide, as this diuretic can lead to potassium depletion, increasing the risk of hypokalemia.
A: Pasta. While pasta is a staple carbohydrate, it does not have a significant potassium content compared to other food sources, making it less suitable for supplementation.
C: Coffee. Although coffee contains some potassium, its levels are relatively low and insufficient for addressing the potassium needs of patients taking furosemide.
D: Angel food cake. This dessert primarily consists of sugar and egg whites, offering minimal potassium and failing to provide the necessary nutrients to counteract the effects of furosemide.

Question 31
Regular
The nurse instructs the client with heart failure to check weight at the same time each day using the same scale. When should the client contact the health care provider?
Correct!
Incorrect
The correct answer is: C
Rationale
If the weight gain is more than 2 lb in 24 hours. Rapid weight gain can indicate fluid retention, a critical concern for clients with heart failure, necessitating prompt medical evaluation to prevent complications.
A: If the weight gain is more than 3 lb in 1 week. This timeframe is too extended; immediate action is essential for daily fluctuations that could signal worsening heart failure.
B: If the weight gain is more than 4 lb in 1 month. A month is a long interval for monitoring; significant changes should be addressed within a much shorter time frame.
D: If the weight gain is more than 1 lb in 48 hours. Although concerning, this threshold is not as urgent as the 2 lb in 24 hours guideline, which indicates immediate risk.
