護理師準備為病人輸注全靜脈營養 (TPN)。管理中心靜脈導管時，哪項護理措施為最高優先？
A nurse is preparing to administer TPN to a client. Which nursing action is the highest priority when managing the central venous catheter?
- AVerify the provider's order against the facility's TPN protocol核對醫囑是否符合機構的 TPN 規範
- BEnsure the catheter is secured to prevent displacement確保導管固定以防止移位
- CUse sterile technique for all line maintenance and connection changes✓ 正解對所有管路維護與連接更換使用無菌技術
- DAssess the insertion site for signs of infection during each dressing change每次更換敷料時評估插入部位是否有感染跡象
— Explanation · 中文詳解 —
全靜脈營養液是細菌培養基，發生導管相關血流感染的風險極高。維持嚴格的無菌技術（Aseptic technique）在連接管路、更換接頭或敷料時至關重要，這是預防醫療照護相關感染的首要防禦機制，保障病人安全。
Total parenteral nutrition serves as an excellent culture medium for bacteria, creating a high risk for catheter-related bloodstream infections. Therefore, maintaining strict aseptic technique during all line maintenance and connections is the highest priority to prevent contamination and ensure patient safety.
✦ 台美臨床差異
美國護理常規對無菌技術的稽核非常嚴格，台灣臨床環境中護理師在更換輸液裝置時同樣要求嚴格執行無菌操作。
