護理師正在照護一名感染困難梭狀芽孢桿菌 (C. diff) 的病人。提供照護後，哪種手部衛生方法最合適？
A nurse is caring for a client with Clostridioides difficile (C. diff) infection. Which hand hygiene method is most appropriate after providing care?
- AWashing hands with soap and water✓ 正解耳毒性
- BRinsing hands with warm water only腎毒性
- CUsing a chlorhexidine gluconate (CHG) wipe光敏感性
- DAlcohol-based hand rub耳鳴
困難梭狀芽孢桿菌（Clostridioides difficile, C. diff）感染是醫療照護相關感染（healthcare-associated infection）中常見且嚴重的問題，尤其在抗生素使用後。C. diff 能產生芽孢（spores），這些芽孢對酒精類乾洗手液具有高度抵抗性，因此傳統的酒精乾洗手無法有效清除。護理師在照護此類病人後，選擇正確的手部衛生方法是阻斷傳播鏈、預防院內感染的關鍵。這不僅關乎病人安全，也是保護其他病人和醫護人員的重要措施。理解病原體的特性，並據此實施精確的感染控制措施，是NCLEX-RN考試中強調的核心能力之一。
Clostridioides difficile forms spores that are resistant to alcohol-based hand sanitizers, making soap and water the most effective hand hygiene method. The mechanical friction and rinsing action of washing with soap and water are necessary to physically remove these spores from the hands, thereby preventing cross-contamination.
關於困難梭狀芽孢桿菌（C. diff）感染的感染控制措施，包括必須使用肥皂和水洗手，而非酒精性乾洗手液的原則，在台灣和美國的臨床實踐中是完全一致的。這是國際公認的感染控制標準。
