Chapter 28 : Caring for Clients With Heart Failure Questions
Question 1 of 5
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 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.
Question 2 of 5
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 Answer: D
Rationale: Elevated blood urea nitrogen indicates impaired renal perfusion in a client with left-sided heart failure. Serum sodium levels may be elevated. Reduced urine output or elevated blood potassium levels do not indicate impaired renal perfusion in a client with left-sided heart failure.
Question 3 of 5
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 Answer: B
Rationale:
To evaluate response to diuretics, a urinary catheter is used. Mechanical ventilation helps maintain a normal breathing pattern. A pulmonary artery catheter helps estimate cardiac output. A biventricular pacemaker is used to sustain life.
Question 4 of 5
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 Answer: A
Rationale: Older adults receiving digitalis preparations are at increased risk for toxicity because of the decreased ability of the kidneys to excrete the drug due to age-related changes. The margin between a therapeutic and toxic effect of digitalis preparations is narrow. Using digitalis preparations does not increase the risk of cardiac arrests, hyperthyroidism, or asthma.
Question 5 of 5
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 Answer: C
Rationale: A procedure known as surgical ventricular restoration (SVR) decreases the size of the heart to a near normal size and shape by removing dysfunctional heart muscle that does not contract properly. Once the adynamic (nonfunctioning) area is removed, the ventricle is repaired with a patch. In the cases that were studied, 91% were free of congestive heart failure after surgery with an ejection fraction that increased from 30% to 40%. A cardiomyoplasty, placement of an external pacemaker, or a ventricular assist device are not considered curative for heart failure.
