A nurse is reinforcing teaching with a client about nutrition.The client has hypertension and is taking a potassium-wasting diuretic.Which of the following dietary instructions should the nurse include in the teaching?
Explanation & Rationale
Choice A rationaleCanned tuna and salmon, while sources of protein and omega-3 fatty acids, are not particularly high in potassium. Clients taking potassium-wasting diuretics need foods rich in potassium to replace the electrolytes lost through increased urination.Choice B rationaleOranges and bananas are excellent sources of potassium. Potassium is an essential electrolyte that is often depleted by potassium-wasting diuretics like furosemide or hydrochlorothiazide. Consuming these fruits helps maintain adequate potassium levels, which are crucial for cardiac function and muscle contraction. The normal range for serum potassium is typically 3.5-5.0 mEq/L.Choice C rationaleDried fruits, such as apricots and raisins, are high in potassium. However, the question asks what the nurse *should* include, and while dried fruits are beneficial, fresh fruits like oranges and bananas are often more readily available and consumed in larger quantities.Choice D rationaleCow's milk contains potassium but is not specifically emphasized for clients on potassium-wasting diuretics. Other food sources like fruits and vegetables generally provide a more direct and often higher concentration of potassium without the added phosphorus and calcium found in milk, which may be considerations for some individuals.
