病人透過中心靜脈導管接受全靜脈營養 (TPN)。預防感染的首要護理措施為何？
A client is receiving total parenteral nutrition (TPN) through a central line. What is the priority nursing action to prevent infection?
- AUse sterile technique for all line care and dressing changes✓ 正解對所有管路照護和敷料更換使用無菌技術
- BDraw blood samples from the TPN lumen從 TPN 管腔抽取血液樣本
- CFlush the line with heparin every 4 hours每 4 小時用肝素沖洗管路
- DChange the TPN tubing every 72 hours每 72 小時更換 TPN 管路

TPN 含有高濃度的葡萄糖和蛋白質，是細菌生長的絕佳培養基。嚴格的無菌技術在更換敷料及導管操作時至關重要，可有效預防導管相關血液感染 (CRBSI)。其餘選項如延長更換時間或錯誤的操作方式皆會增加感染風險。
Total parenteral nutrition (TPN) contains high concentrations of glucose and protein, creating an ideal medium for bacterial growth. Therefore, strict sterile technique is mandatory during all line care and dressing changes to effectively prevent catheter-related bloodstream infections (CRBSI). Other options, such as extending tubing change intervals or using non-sterile practices, significantly increase the risk of infection.
✦ 台美臨床差異
台美皆嚴格執行無菌技術，但美國護理師常使用針頭無針接頭系統，台灣則視院方採購設備而定。
