護理師照護一位裝置中心靜脈導管的病人，哪項措施對於預防導管相關血流感染最為重要？
A nurse is caring for a client with a central venous catheter. Which action is essential to prevent a central line-associated bloodstream infection?
- AKeep the line as long as possible for future use盡可能延長留置時間以供未來使用
- BPerform scrub-the-hub technique before accessing the port✓ 正解在存取端口前執行擦拭消毒技術
- CChange the dressing every day每天更換敷料
- DFlush the catheter with heparin daily每天用肝素沖洗導管
預防中心靜脈導管感染（CLABSI）的核心是無菌技術。存取端口前執行「刷洗接口」（scrub-the-hub）程序可機械性清除細菌，顯著降低感染風險。敷料更換頻率依醫院規範而定，無需每日更換；肝素沖洗是為了防止血栓；過度留置不必要的管路反而增加感染危險。
The core of preventing central line-associated bloodstream infection (CLABSI) is aseptic technique. Performing the 'scrub-the-hub' procedure before accessing the port mechanically removes bacteria and significantly reduces infection risk. Dressing change frequency depends on hospital policy and does not require daily changes; heparin flushing is to prevent thrombus formation; leaving unnecessary catheters in place actually increases the risk of infection.
美國護理界普遍遵循 Bundle of care（護理包策略），台灣在臨床實踐中亦積極推動相關預防措施，降低導管感染率。
