護理師照顧一位困難梭狀桿菌感染的病人。採取下列哪項措施最能預防感染傳播？
A nurse is caring for a client with Clostridium difficile infection. Which action is the most critical to prevent transmission?
- AWash hands with soap and water after patient contact✓ 正解接觸病人後用肥皂和水洗手
- BWear a N95 respirator when entering the room進入病房時佩戴 N95 呼吸器
- CPlace the client in a negative pressure room將病人安置於負壓病房
- DUse alcohol-based hand sanitizer after patient contact接觸病人後使用酒精性搓手液

困難梭狀桿菌（Clostridium difficile）會產生芽孢，這些芽孢對一般酒精性乾洗手液具有抗性，因此在照顧此類病人時，酒精洗手液無法有效殺滅芽孢。為了防範傳播，護理師必須使用肥皂與清水洗手，透過物理性的機械摩擦去除手上的芽孢。這是感染管制中極為關鍵的步驟，若僅使用酒精洗手，將無法達到預期的隔離效果。
Clostridium difficile produces spores that are resistant to ordinary alcohol-based hand sanitizers; therefore, when caring for these clients, alcohol hand rubs cannot effectively kill the spores. To prevent transmission, the nurse must wash hands with soap and water, using physical mechanical friction to remove the spores from the hands. This is a critical step in infection control; relying on alcohol alone will not achieve the expected isolation effect.
