預防中心靜脈導管相關血流感染（CLABSI），護理師應採取何種行動？
Which action should the nurse take to prevent a central line-associated bloodstream infection (CLABSI)?
- AChange the dressing every 24 hours每 24 小時更換敷料
- BPerform hand hygiene before touching the line✓ 正解接觸導管前執行手部衛生
- CUse sterile gloves for every routine assessment每次常規評估都使用無菌手套
- DAdminister prophylactic antibiotics給予預防性抗生素
預防中心靜脈導管相關血流感染（CLABSI）的核心原則是嚴格遵循無菌技術及手部衛生。手部衛生是阻斷病原體透過醫護人員手部傳播至導管口的最有效途徑。其他措施如定期更換敷料（根據醫院政策，並非固定 24 小時）、不常規使用預防性抗生素（會增加抗藥性）及 routine 評估時不一定需戴無菌手套（視操作類型而定）。
The core principle of preventing central line-associated bloodstream infection (CLABSI) is strict adherence to aseptic technique and hand hygiene. Hand hygiene is the most effective way to interrupt pathogen transmission via the healthcare worker's hands to the catheter hub. Other measures, such as routine dressing changes (per hospital policy, not strictly every 24 hours), avoidance of routine prophylactic antibiotics (which increase resistance), and the routine use of sterile gloves during assessment (which depends on the type of procedure), are secondary.
