病人正在接受全靜脈營養（TPN）。護理師應監測哪項併發症？

全靜脈營養（Total Parenteral Nutrition, TPN）溶液含有高濃度的葡萄糖、胺基酸及電解質，其高滲透壓特性使得病人極易出現血糖代謝異常。高血糖（Hyperglycemia）是 TPN 最常見的代謝併發症，主要源於身體無法即時處理過高濃度的外源性糖分。護理師必須嚴格遵守輸注速率，不可為了補進度而驟然加速，並定時監測指尖血糖，必要時依醫囑給予胰島素（Regular Insulin）控制，以維護病人代謝穩定。

Total parenteral nutrition (TPN) solutions contain high concentrations of glucose, amino acids, and electrolytes, and their hyperosmolar nature makes glucose metabolism disturbances extremely likely. Hyperglycemia is the most common metabolic complication of TPN, primarily because the body cannot promptly process the high concentration of exogenous glucose. The nurse must strictly maintain the infusion rate, must not increase it abruptly to 'catch up,' and must monitor fingerstick blood glucose at regular intervals, administering regular insulin per provider order as needed to preserve the client's metabolic stability.
