A nurse is assisting with a presentation about caring for clients who are receiving diuretic therapy. The nurse should explain that which of the following medications can put clients at risk for hyperkalemia?

A. Furosemide: Loop diuretics cause potassium loss (hypokalemia), not hyperkalemia. B. Spironolactone: Potassium-sparing aldosterone antagonist - it reduces K⁺ excretion and can cause hyperkalemia. C. Hydrochlorothiazide: Thiazide diuretic increases renal K⁺ excretion and typically causes hypokalemia, not hyperkalemia. D. Bumetadine: (Bumetanide) Loop diuretic like furosemide - causes K⁺ loss and risk of hypokalemia, not hyperkalemia.
