護理師照護一位血清鉀離子濃度為 3.2 mEq/L 的病人。護理師應建議病人食用下列哪種食物？
A nurse is caring for a client with a serum potassium level of 3.2 mEq/L. Which food item should the nurse suggest the client consume?
- ABananas✓ 正解香蕉
- BBoiled eggs水煮蛋
- CApple juice蘋果汁
- DWhite rice白米飯
低血鉀（血鉀 < 3.5 mEq/L）的核心概念是透過飲食或藥物補充來維持神經肌肉與心肌的正常生理功能。香蕉是眾所周知的高鉀食物，適合輕度低血鉀病人的日常補充。選項 D、C、B 雖然也是健康的食物，但其鉀含量相對較低。在臨床思路上，對於使用排鉀利尿劑的病人，護理師應主動衛教含鉀量高的食物清單，如深綠色蔬菜、馬鈴薯與柑橘類，這屬於基礎的生理適應照護範疇，旨在預防潛在的心律不整風險。
The core concept of hypokalemia (serum potassium < 3.5 mEq/L) is to maintain normal neuromuscular and cardiac function through dietary or pharmacological potassium replacement. Bananas are a well-known high-potassium food and are appropriate for routine dietary supplementation in clients with mild hypokalemia. Options D, C, and B are healthy foods but have relatively low potassium content. Clinically, for clients taking potassium-wasting diuretics, the nurse should proactively teach about high-potassium foods, such as dark leafy greens, potatoes, and citrus fruits, which fall under basic physiological adaptation care aimed at preventing potential cardiac dysrhythmias.
美國護理師常直接依據衛教手冊建議病人攝取高鉀食物；台灣則多由護理師初步指導後，若血鉀持續偏低，會轉介營養師進行更詳細的限鈉高鉀飲食衛教。
