評估病人的營養狀況時，下列哪項實驗室數據是長期蛋白質狀態最可靠的指標？
When assessing a client's nutritional status, which laboratory finding is the most reliable indicator of long-term protein status?
- AHemoglobin血紅素
- BTransferrin轉鐵蛋白
- CSerum albumin✓ 正解血清白蛋白
- DPrealbumin前白蛋白
— Explanation · 中文詳解 —
血清白蛋白（Albumin）的半衰期長（約 20 天），能反映過去數週到數個月的營養貯備情況，為慢性營養不良的指標。Prealbumin 半衰期短（約 2 天），主要反映近期 1 週內的營養變化，而非長期狀態。
Serum albumin is the most reliable indicator of long-term protein status because it has a long half-life of approximately 20 days, reflecting nutritional reserves over weeks to months. In contrast, prealbumin has a short half-life and indicates recent changes, while hemoglobin and transferrin are influenced by other factors like iron status rather than being specific to protein stores.
