An adult who has hypertension is taking furosemide (Lasix). The client has been placed on a low-sodium, high-potassium diet. What is the reason for the potassium alteration?

ExplanationFurosemide (Lasix) is a potassium-depleting diuretic. Persons taking furosemide should increase their intake of potassium to replace the potassium lost in the urine. A high-potassium diet does not prevent sodium loss from the renal tubules. Sodium loss from the renal tubules is the mechanism by which furosemide works. Potassium in the diet does not prevent osteoporosis secondary to diuresis. Dietary potassium is not increased to maintain acid-base balance.
