艱難梭菌會產生孢子，酒精無法殺死孢子，因此接觸此類病人後必須使用肥皂及流水進行濕洗手，透過物理移除機械性清潔。D 錯誤：酒精無法破壞孢子；B 錯誤：此菌為接觸傳染，不需負壓隔離；C 錯誤：此菌非空氣傳染，不需 N95。
C. difficile produces spores that alcohol cannot destroy; therefore, after caring for these clients, hand hygiene must be performed with soap and running water to physically remove spores. D is wrong: alcohol cannot kill spores. B is wrong: this organism is transmitted by contact, not airborne, so negative pressure is unnecessary. C is wrong: an N95 respirator is for airborne precautions, not contact.
