1. JoAnn Smith is a 72-year-old woman with a
history of myocardial infarction four years ago
and systolic heart failure. Her current ejection
fraction is 15%. Which classification of heart
failure does she have?
A. HFpEF
B. HFmrEF
C. HFrEF
D. HFimpEF
Rationale: HFrEF is defined as an LVEF of 40%
or less. JoAnn's EF of 15% places her in the
severely reduced category.
, 2. Which underlying pathophysiologic process
most directly explains JoAnn's development of
heart failure?
A. Ischemic cardiomyopathy
B. Valvular stenosis
C. Pericardial tamponade
D. Hypertrophic obstructive cardiomyopathy
Rationale: JoAnn's history of MI led to ischemic
damage to the myocardium, resulting in ischemic
cardiomyopathy and systolic dysfunction.
3. JoAnn presents with coarse crackles scattered
throughout both lung fields and labored
respiratory effort. These findings are most
consistent with which type of heart failure?
A. Right-sided heart failure
B. Left-sided heart failure
C. Isolated right ventricular failure
D. Cor pulmonale
Rationale: Left-sided heart failure causes
pulmonary congestion, leading to crackles,
dyspnea, and orthopnea.
, 4. Which assessment finding would the nurse
expect to observe in JoAnn due to her right-
sided heart failure component?
A. Pink frothy sputum
B. Bibasilar crackles
C. 3+ pitting edema in lower extremities
D. Orthopnea
Rationale: Right-sided heart failure leads to
systemic venous congestion, manifesting as
peripheral edema, JVD, and weight gain.
5. JoAnn's heart rhythm is irregular, and she has a
history of atrial fibrillation. Which medication
would the nurse anticipate being prescribed for
rate control?
A. Furosemide
B. Metoprolol
C. Digoxin
D. Nitroglycerin
Rationale: Beta-blockers such as metoprolol are
used for rate control in atrial fibrillation and to
reduce myocardial workload in heart failure.
, 6. The nurse is reviewing JoAnn's medication
orders. Furosemide 40 mg IV push is ordered.
Which laboratory value should the nurse
monitor most closely after administration?
A. Hemoglobin
B. Potassium
C. Calcium
D. Magnesium
Rationale: Furosemide is a loop diuretic that
causes potassium loss, increasing the risk for
hypokalemia and dysrhythmias.
7. Which assessment finding indicates that JoAnn's
furosemide therapy is effective?
A. Increased jugular venous distention
B. Increased urine output
C. Weight gain of 2 kg
D. Development of S3 heart sound
Rationale: Effective diuresis is evidenced by
increased urine output and subsequent reduction
in fluid overload.
