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?
- A. Avoid any activity at least 2 hours before the test.
- B. Drink plenty of fluids during the test.
- C. Avoid dairy products a day before and a day after the test.
- D. Lie very still at intermittent times during the test.
Correct Answer: D
Rationale: The nurse should instruct the client, who is to undergo a MUGA scan, to lie very still at intermittent times during the 45-minute test. The client need not drink plenty of fluids, avoid activities before/after the test, or avoid dairy products during the test.

What disease process(es) contributes to chronic heart failure? Select all that apply.
- A. Tachyarrhythmias
- B. Valvular disease
- C. Pancreatic disease
- D. Renal failure
- E. Pulmonary insufficiency
Correct Answer: A,B,D
Rationale: Hypertension, tachyarrhythmias, valvular disease, cardiomyopathy, and renal failure can contribute to chronic heart failure. Pancreatic disease and pulmonary insufficiency do not contribute to chronic heart failure.
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?
- A. An angiotensin converting enzyme inhibitor (ACE) inhibitor
- B. A thiazide diuretic
- C. An angiotensin receptor blocker (ARB)
- D. A calcium channel blocker
Correct Answer: A
Rationale: Captopril is an ACE inhibitor. Although the other medications may be used alone or in conjunction with other medications, the ACE inhibitor is a standard medication used in heart failure unless not tolerated by the client.
A client is awaiting the availability of a heart for transplant. What option may be available to the client as a bridge to transplant?
- A. Implanted cardioverter-defibrillator (ICD)
- B. Pacemaker
- C. Intra-aortic balloon pump (IABP)
- D. Ventricular assist device (VAD)
Correct Answer: D
Rationale: VADs may be used for one of three purposes: (1) a bridge to recovery, (2) a bridge to transport, or (3) destination therapy (mechanical circulatory support when there is no option for a heart transplant). An implanted cardioverter-defibrillator or pacemaker is not a bridge to transplant and will only correct the conduction disturbance and not the pumping efficiency. An IABP is a temporary, secondary mechanical circulatory pump to supplement the ineffectual contraction of the left ventricle. The IABP is intended for only a few days.
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?
- A. BNP of 100
- B. Sodium level of 135
- C. Hemoglobin of 12
- D. Potassium level of 3.1
Correct Answer: D
Rationale: Severe heart failure usually requires a loop diuretic such as furosemide (Lasix). These drugs increase sodium and therefore water excretion, but they also increase potassium excretion. If a client becomes hypokalemic, digitalis toxicity is more likely. The BNP does not demonstrate a severe heart failure. Sodium level of 135 is within normal range, as is the hemoglobin level.
The nurse is caring for a client in the hospital with chronic heart failure that has marked limitations in his physical activity. The client is comfortable when resting in the bed or chair, but when ambulating in the room or hall, he becomes short of breath and fatigued easily. What type of heart failure is this considered according to the New York Heart Association (NYHA)?
- A. Class I (Mild)
- B. Class II (Mild)
- C. Class III (Moderate)
- D. Class IV (Severe)
Correct Answer: C
Rationale: Class III (Moderate) is when there is marked limitation of physical activity. The client is comfortable at rest, but less than ordinary activity causes fatigue, heart palpitations, or dyspnea. Class I is ordinary physical activity does not cause undue fatigue, palpitations, or dyspnea. The client does not experience any limitation of activity. Class II (Mild) is when the client is comfortable at rest, but ordinary physical activity results in fatigue, heart palpitations, or dyspnea. Class IV (Severe), the client is unable to carry out any physical activity without discomfort. Symptoms of cardiac insufficiency occur at rest. Discomfort is increased if any physical activity is undertaken.
