護理師照護一位困難梭狀芽孢桿菌（C. difficile）檢測呈陽性的病人。下列哪項感染控制措施是優先順序最高的？
A nurse is caring for a client who has a positive result for Clostridium difficile. Which action is the highest priority for infection control?
- APlace the client in a room with negative pressure airflow將病人安置於負壓氣流的房間
- BUse an alcohol-based hand sanitizer after patient contact與病人接觸後使用酒精性手部消毒劑
- CWear a N95 respirator during all client interactions在所有病人互動期間佩戴 N95 呼吸器
- DPerform hand hygiene using soap and water✓ 正解使用肥皂和水進行手部衛生
— Explanation · 中文詳解 —
困難梭狀芽孢桿菌會產生孢子，酒精乾洗手無法殺死孢子，必須使用流動水與肥皂洗手以透過物理摩擦移除孢子。B 錯誤，酒精無法滅活孢子；A 錯誤，C. diff 採取接觸防護，非空氣防護；C 錯誤，此菌無需佩戴 N95。
Clostridium difficile produces spores that are resistant to alcohol-based hand sanitizers, making mechanical removal with soap and water essential for infection control. While contact precautions are required, negative pressure rooms and N95 respirators are unnecessary as this pathogen is not airborne.
✦ 台美臨床差異
美台對於 C. diff 的感染控制規範一致，皆強制規定執行接觸預防措施與肥皂洗手。
