護理師評估一名慢性腎臟病 (CKD) 病人。哪項實驗室數值顯示需要執行低蛋白飲食？

慢性腎臟病 (CKD) 病人由於腎功能受損，無法有效過濾和排出體內的代謝廢物。其中，血尿素氮 (BUN) 是蛋白質代謝的最終產物，主要經由腎臟排出。當腎功能下降時，BUN 會在體內堆積，導致尿毒症狀。因此，監測 BUN 數值對於評估 CKD 病人的蛋白質攝取量至關重要。若 BUN 升高，則表示病人體內蛋白質代謝產物過多，需要限制飲食中的蛋白質攝取，以減輕腎臟負擔，延緩疾病進展並緩解尿毒症狀。護理師應根據病人的腎功能階段和實驗室數值，與醫師及營養師協同合作，提供個別化的低蛋白飲食衛教，確保病人獲得足夠的熱量且不會過度消耗自身蛋白質。

Clients with chronic kidney disease (CKD) have impaired renal function and cannot effectively filter or excrete metabolic waste. Among these waste products, blood urea nitrogen (BUN) is the end product of protein metabolism, which is excreted primarily through the kidneys. When renal function declines, BUN accumulates in the body and causes uremic symptoms. Therefore, monitoring BUN is essential for evaluating protein intake in clients with CKD. Elevated BUN indicates excess protein metabolic byproducts in the body, requiring restriction of dietary protein to reduce renal workload, slow disease progression, and relieve uremic symptoms. The nurse should collaborate with the physician and dietitian based on the client's stage of renal function and laboratory values to provide individualized low-protein dietary education, ensuring the client receives adequate calories without excessive depletion of body protein.

在美國，CKD 病人的飲食管理非常強調與註冊營養師 (Registered Dietitian, RD) 合作，護理師主要負責衛教和監測。台灣的護理師在飲食衛教中也扮演重要角色，但營養師的角色同樣關鍵。低蛋白飲食的具體建議量（如 0.6-0.8 g/kg/day）會依據腎臟病分期和病人狀況而定，台美指引基本一致。
