Final answer:
Aldosterone and spironolactone both cause the kidneys to retain potassium. It is important for the nurse to teach the patient to limit high potassium foods.
Step-by-step explanation:
OALDOSTERONE is a hormone that increases the reabsorption of sodium and the excretion of potassium in the distal tubules of the kidneys. This hormone is released in response to high levels of potassium in the blood. Spironolactone, a potassium-sparing diuretic, also helps the kidneys retain potassium. Therefore, it is important for the nurse to teach the patient to limit foods that are high in potassium.
