護理師照護一位感染困難梭狀芽孢桿菌的病人。下列哪項護理行為顯示其了解接觸隔離措施？
A nurse is caring for a client with Clostridium difficile. Which action by the nurse demonstrates understanding of contact precautions?
- AWashing hands with alcohol-based hand sanitizer使用含酒精的乾洗手液洗手
- BUsing soap and water for hand hygiene✓ 正解使用肥皂和水進行手部衛生
- CWearing a surgical mask upon entering the room進入房間時佩戴外科口罩
- DPlacing the client in a negative pressure room將病人安置於負壓隔離室
困難梭狀芽孢桿菌（C. difficile）會產生具抗藥性的「孢子」。酒精性乾洗手液無法殺滅孢子，反而可能透過物理塗抹讓孢子擴散。標準預防措施（Contact Precautions）明確要求，在處理此類感染病人後，必須使用肥皂與水進行洗手，利用機械式摩擦（Mechanical friction）將孢子物理性清除。這是 NCLEX 考題中關於感染控制的經典必考題，重點在於區分酒精與肥皂洗手的適用情境。
Clostridium difficile produces resistant spores. Alcohol-based hand sanitizer cannot kill these spores and may simply spread them through physical contact. Contact precautions explicitly require hand washing with soap and water after caring for these clients, using mechanical friction to physically remove the spores. This is a classic NCLEX infection control question that hinges on distinguishing when to use alcohol-based sanitizer versus soap and water.
台美臨床指引對於 C. diff 的接觸隔離要求一致，均強調必須使用肥皂與水洗手（Soap and water），而非酒精乾洗手液。
