護理師照護一位困難梭狀桿菌陽性病人，哪項措施是感染控制的首要任務？
A nurse is caring for a client who has a positive result for Clostridium difficile. Which action is the priority for infection control?
- APlace the client in a negative pressure isolation room將病人安置於負壓隔離室
- BUse an alcohol-based hand sanitizer after patient contact接觸病人後使用酒精性乾洗手液
- CImplement contact precautions including soap and water hand hygiene✓ 正解實施接觸隔離措施，包括使用肥皂和水進行手部衛生
- DWear a N95 respirator when entering the room進入房間時佩戴N95呼吸防護器

困難梭狀桿菌（C. difficile）會形成芽孢（Spore），這些芽孢具有極高的環境抗性，無法被酒精基底的乾洗手液（Alcohol-based hand sanitizer）殺滅。因此，接觸此類病人後，必須執行「機械式移除」，即使用肥皂與水洗手。這是感染控制的核心，旨在防止芽孢經由醫護人員的手部傳播給其他易感病人。
Contact precautions with soap and water hand hygiene are essential because C. difficile spores are resistant to alcohol-based sanitizers. Mechanical removal via washing is required to prevent transmission, whereas negative pressure rooms and N95 respirators are unnecessary for contact-borne pathogens.
