病人正在接受全靜脈營養（TPN）輸注。哪項護理行動對於預防併發症最為關鍵？
A client is receiving total parenteral nutrition (TPN). Which nursing action is most critical to prevent complications?
- AUsing a dedicated central venous access line✓ 正解使用專屬的中心靜脈導管
- BChecking blood glucose every 6 hours每 6 小時檢查血糖
- CChanging the TPN bag every 48 hours每 48 小時更換 TPN 袋
- DAdding medications to the TPN bag將藥物加入 TPN 袋中
— Explanation · 中文詳解 —
TPN 高滲透壓且營養豐富，極易成為細菌溫床。專用導管通道（dedicated line）可大幅減少因共用管路而引發的感染風險。雖然監測血糖（選項 B）很重要，但感染預防在 TPN 管理中屬於核心安全項目。選項 C 的更換頻率通常較短，選項 D 為護理禁忌，嚴禁擅自添加藥物。
TPN is hyperosmolar and nutrient-rich, making it an ideal medium for bacterial growth. A dedicated central line greatly reduces infection risk from shared tubing. While monitoring glucose (B) is important, infection prevention is the core safety concern in TPN management. Option C (every 48 hours) is too long—bags are changed every 24 hours. Option D is contraindicated; nurses must not add medications to TPN.
✦ 台美臨床差異
台美對 TPN 的無菌操作規範均極度嚴格，皆要求使用專用管路與無菌技術進行維護。
