A nurse is caring for a group of clients. The nurse should monitor which of the following clients for manifestations of hypokalemia? (Select all tha apply.)

A. "A client taking prednisone": Prednisone is a corticosteroid that can cause potassium depletion, increasing the risk of hypokalemia. Monitoring for signs of low potassium, such as muscle weakness or arrhythmias, is important. B. "A client taking torsemide": Torsemide is a loop diuretic, which increases potassium excretion in the urine. This can lead to hypokalemia, so clients on this medication should be closely monitored for symptoms of low potassium. C. "A client taking polystyrene sulfonate": This medication treats hyperkalemia by binding potassium in the gut and removing it from the body, which can lead to hypokalemia. D. "A client taking spironolactone": Spironolactone is a potassium-sparing diuretic. It works to retain potassium, and therefore, it is unlikely to cause hypokalemia. It may actually increase potassium levels. E. "A client taking hydrochlorothiazide": Hydrochlorothiazide is a thiazide diuretic, which can lead to potassium loss through increased urinary excretion. This increases the risk for hypokalemia, so monitoring potassium levels is necessary.
