The client with a history of heart failure is prescribed spironolactone (Aldactone). The nurse should monitor for which potential side effect?
Correct answer
B
Rationale
Spironolactone, a potassium-sparing diuretic, can cause hyperkalemia by reducing potassium excretion. Hypokalemia is caused by other diuretics, hypoglycemia is unrelated, and spironolactone lowers blood pressure.
