The nurse is administering captopril to a patient with heart failure. Which assessment finding would prompt the nurse to withhold the next dose and notify the physician?
A) Hypertension
B) Third (S3) heart sound
C) Dyspnea and crackles
D) Hyperkalemia
Ans: D
Feedback: Captopril is an angiotensin-converting enzyme (ACE) inhibitor administered to patients with heart failure to improve functional capacity. Hyperkalemia is an adverse effect of ACE-inhibiting medications, which inhibit potassium excretion. If the patient is hyperkalemic, the nurse should notify the physician before administering the next dose. Hypertension is an indication for the use of captopril, not an adverse effect. If captopril causes hypotension, the physician should be notified. An S3, dyspnea, and crackles are signs of heart failure and indications for the use of ACE-inhibiting medications, not adverse effects.
