病人經由中心靜脈導管接受全靜脈營養(TPN)。目前藥袋已空,但藥劑科尚未送來新藥袋。護理師應先掛上哪種點滴?
A client is receiving total parenteral nutrition (TPN) via a central line. The TPN bag is empty, and the new bag is not available from the pharmacy. Which IV fluid should the nurse hang?
- A10% Dextrose in Water (D10W)✓ 正解10% 葡萄糖水溶液 (D10W)
- B0.9% Normal Saline0.9% 生理食鹽水
- C5% Dextrose in Water (D5W)5% 葡萄糖水溶液 (D5W)
- DLactated Ringer's solution乳酸林格氏液

TPN 含有高濃度葡萄糖。若突然停止,胰島素分泌尚未調整,會導致嚴重反彈性低血糖(Rebound hypoglycemia)。掛上 10% 葡萄糖水(D10W)可以維持血糖穩定,直到新的 TPN 送達。5% 葡萄糖不足以維持 TPN 等級的血糖需求。
When a TPN bag is empty and a replacement is unavailable, the nurse should hang 10% Dextrose in Water (D10W) to prevent rebound hypoglycemia. TPN contains high concentrations of glucose, and abrupt discontinuation can cause a dangerous drop in blood sugar levels. D10W provides sufficient glucose to maintain stability until the new TPN infusion is ready.
✦ 台美臨床差異
台美臨床處理原則一致。但在美國 NCLEX 中,D10W 被視為 TPN 中斷時唯一正確的預防低血糖選項。
