病人正在接受全靜脈營養（TPN），哪項護理措施為優先？
A client is receiving total parenteral nutrition (TPN). What is the priority nursing intervention?
- ACheck blood glucose levels every 4-6 hours✓ 正解每 4-6 小時檢查血糖
- BStore the TPN solution in the supply closet將全靜脈營養（TPN）溶液存放在供應室
- CAdminister the TPN as fast as possible盡快給予全靜脈營養（TPN）
- DChange the IV tubing once a week每週更換一次靜脈輸液管路
— Explanation · 中文詳解 —
TPN 含有高濃度葡萄糖，極易導致高血糖。定時監測血糖可預防高滲透壓非酮酸性昏迷。管路更換頻率依醫院規定（通常 24 小時），TPN 需恆速輸入，絕對不能過快。TPN 必須儲存於冰箱內，不可置於常溫櫃中。
TPN contains a high concentration of glucose, which readily produces hyperglycemia. Regular blood glucose monitoring prevents hyperosmolar nonketotic coma. The frequency of tubing changes follows institutional policy (typically every 24 hours), TPN must be infused at a constant rate and must never be run too fast, and the solution must be stored in the refrigerator rather than at room temperature.
✦ 台美臨床差異
美國護理師常執行 TPN 血糖控制 protocol，台灣則多依照醫師醫囑執行，且在給藥準確性要求上兩地皆極高。
