A client with heart failure (HF) develops hyperaldosteronism and spironolactone is prescribed. Which instruction should the nurse include in the client's plan of care?

A. Spironolactone is a potassium-sparing diuretic; therefore, it is important to limit potassium intake to prevent hyperkalemia. B. Skin protection is not a specific concern related to spironolactone use. C. Spironolactone does not commonly cause excessive bruising; monitoring for signs of hyperkalemia is more relevant. D. Using a salt substitute may increase potassium intake, which is contraindicated with spironolactone.
