護理師照顧一位剛確診慢性腎臟病的病人，哪項飲食衛教最重要？
A nurse is caring for a client with a new diagnosis of chronic kidney disease. Which dietary instruction is most important?
- AConsume unlimited water無限制飲用水
- BIncrease potassium-rich food intake增加富含鉀的食物攝取
- CMonitor protein intake as prescribed✓ 正解遵照指示監測蛋白質攝取量
- DAdd extra salt to improve food palatability添加額外鹽分以提升食物風味
慢性腎臟病（Chronic Kidney Disease, CKD）的飲食管理目標在於減輕腎臟負擔並延緩腎功能惡化。蛋白質代謝產生的含氮廢物需經由腎臟排泄，因此限制蛋白質攝取可減少尿毒素堆積。正確的臨床思路是依據病人的腎絲球過濾率（GFR）來調整蛋白質攝取量，過多會增加腎臟負擔，過少則會導致營養不良，必須精確執行醫囑。
The dietary goals for chronic kidney disease (CKD) are to reduce renal workload and slow the decline in kidney function. Nitrogenous waste products from protein metabolism must be excreted by the kidneys, so limiting protein intake decreases uremic toxin accumulation. Clinically, protein intake should be titrated based on the client's glomerular filtration rate (GFR): too much increases renal burden, while too little leads to malnutrition, so the prescription must be followed precisely.
美國臨床更依賴註冊營養師（Registered Dietitian, RD）與腎臟科團隊合作，透過專業評估制定個別化飲食計畫，護理師的角色為落實與監測病人的依從性。
