護理師照護一位困難梭狀桿菌（C. difficile）感染的病人，哪種手部衛生方法最有效以防止傳播？
A nurse is caring for a client with Clostridioides difficile. Which hand hygiene method is most effective for preventing transmission?
- AUsing alcohol-based hand rub使用含酒精的搓手液
- BUsing sterile gloves only僅使用無菌手套
- CUsing antiseptic foam scrub使用抗菌泡沫洗手劑
- DWashing hands with soap and water✓ 正解用肥皂和水洗手
接觸困難梭狀桿菌（C. difficile）病人時，標準預防措施為接觸隔離（Contact Precautions）。該細菌產生的孢子（Spores）對酒精具有高度抵抗力，一般的酒精性乾洗手液（Alcohol-based hand rub）無法殺滅或移除孢子。因此，必須使用肥皂（Soap）與清水（Water）透過物理性的機械沖刷（Mechanical friction），才能有效移除手部的孢子，這是預防院內交叉感染的關鍵。
When caring for a client with Clostridioides difficile, the standard precaution required is contact isolation. The spores produced by this organism are highly resistant to alcohol, so ordinary alcohol-based hand rubs cannot kill or remove the spores. Therefore, soap and water must be used to physically and mechanically wash off the spores from the hands, which is essential to prevent nosocomial cross-transmission.
