一位接受靜脈營養（PN）的病人，哪項評估最重要？
Which assessment is most important for a client receiving parenteral nutrition (PN)?
- ADaily weights每日體重
- BSerum potassium血清鉀
- CBlood glucose levels✓ 正解血糖值
- DUrine output尿量
— Explanation · 中文詳解 —
靜脈營養（Parenteral nutrition, PN）含有高濃度的葡萄糖、胺基酸與電解質，極易引發嚴重的高血糖。監測血糖是 PN 照護中最關鍵的項目，護理師需根據血糖值調整輸注速率及胰島素給予量，以預防高滲透性高血糖狀態。其他指標如體重、電解質、尿量雖重要，但血糖的急性波動對生命安全威脅最大。
Parenteral nutrition contains high concentrations of glucose, posing a significant risk for hyperglycemia. Therefore, monitoring blood glucose levels is the most critical assessment to prevent acute complications like hyperosmolar hyperglycemic state. While daily weights, serum potassium, and urine output are important for overall fluid and electrolyte balance, they do not address the immediate metabolic threat posed by PN.
