在臨床環境中，預防困難梭狀芽孢桿菌（C. difficile）傳播，護理師採取哪項措施最有效？
Which action is most effective for a nurse to prevent the transmission of Clostridioides difficile in a clinical setting?
- AWearing a surgical mask when entering the room進入病房時配戴外科口罩
- BPlacing the client in a negative-pressure airflow room將病患安置於負壓氣流病房
- CPerforming hand hygiene with soap and water after patient care✓ 正解病患照護後使用肥皂和水進行手部衛生
- DUsing alcohol-based hand sanitizer after every contact每次接觸後使用酒精性手部消毒液

困難梭狀芽孢桿菌會產生具抗藥性的芽孢，酒精無法殺死芽孢，必須透過物理性洗手（皂液加流水）將其沖洗掉。A 為無效手段；C 此病為接觸隔離非飛沫傳播，口罩非必須；D 負壓病房用於空氣傳染病，不適用於接觸隔離。
Clostridioides difficile produces antibiotic-resistant spores that cannot be killed by alcohol; therefore, mechanical hand washing with soap and running water is required to physically remove the spores. Option D is ineffective; option A is incorrect because this organism is transmitted via contact rather than droplets, so a mask is not required; option B is incorrect because negative-pressure rooms are used for airborne diseases, not for contact precautions.
