— 安全與感染控制 · EASY · MCQ —
護理師照護的一位住院病人確診困難梭狀芽孢桿菌（C. difficile）。下列何項感染控制措施最為關鍵？
A nurse is caring for a client in a semi-private room who has developed Clostridioides difficile. Which action is most important for infection control?
- APlace the client on droplet precautions將病人實施飛沫隔離
- BPerform hand hygiene using soap and water✓ 正解使用肥皂和水執行手部衛生
- CWear a N95 respirator when entering the room進入病房時佩戴 N95 呼吸器
- DUse an alcohol-based hand rub after patient contact接觸病人後使用酒精性搓手液
— Explanation · 中文詳解 —
C. difficile 的芽孢無法被酒精殺死，因此接觸病人後必須使用肥皂與水洗手以物理性移除芽孢。酒精乾洗手對於該菌無效，且該菌採取接觸隔離（Contact Precautions）而非飛沫或空氣隔離，故不需要 N95 口罩。
Clostridioides difficile spores are resistant to alcohol-based hand sanitizers, making soap and water essential for physical removal. Contact precautions are required, not droplet or airborne precautions, so a N95 respirator is unnecessary.
