一位接受全靜脈營養（TPN）的病人，藥袋已滴完但藥劑部尚未送來下一袋。護理師應採取哪項行動？
A client receiving total parenteral nutrition (TPN) has the infusion bag run out before the next bag arrives from the pharmacy. Which action should the nurse take?
- ACap the central line until the new TPN bag is available封鎖中心靜脈導管，直到新的 TPN 藥袋到位
- BHang 0.9% normal saline to maintain line patency輸注 0.9% 生理食鹽水以維持管路暢通
- CInfuse 10% dextrose in water (D10W) at the same rate✓ 正解以相同速率輸注 10% 葡萄糖水（D10W）
- DSlow the current TPN rate to 10 mL/hr to make it last將目前 TPN 的滴速減慢至 10 mL/hr 以延長使用時間
TPN 含有高濃度的葡萄糖，會刺激胰島素持續大量分泌。如果突然停止輸注，病人可能發生嚴重的反彈性低血糖（Rebound Hypoglycemia）。當下一袋 TPN 延誤時，護理師應掛上 10% 葡萄糖液（D10W）以維持血糖穩定，直到新的 TPN 袋送達。不可僅使用 NS 或封管，因為它們不含糖分。
TPN contains a high concentration of dextrose that stimulates ongoing high-level insulin secretion. If the infusion is abruptly stopped, the client may experience severe rebound hypoglycemia. When the next TPN bag is delayed, the nurse should hang 10% dextrose in water (D10W) to maintain blood glucose stability until the new TPN bag arrives. Normal saline alone or capping the line is not appropriate because neither contains glucose.
美國 NCLEX 考題標竿為 D10W；台灣臨床有時根據醫囑使用 D5W 或 D10W，但原則皆為防止低血糖。
