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

A. Limit the intake of foods high in potassium: Spironolactone is a potassium-sparing diuretic, which means it can cause potassium levels to rise. Therefore, the nurse should advise the patient to limit the intake of potassium-rich foods to avoid hyperkalemia. B. Cover your skin before going outside: This instruction is not specifically related to the use of spironolactone. It is more relevant for medications that cause photosensitivity or skin reactions. C. Replace salt with a salt substitute: Many salt substitutes contain potassium, which could increase the risk of hyperkalemia when taking spironolactone. Therefore, replacing salt with a potassium-containing salt substitute is not recommended. D. Monitor skin for excessive bruising: While monitoring for bruising is important, it is more relevant for anticoagulants or medications that affect blood clotting, not specifically for spironolactone.
