護理師正在照護一名感染困難梭狀芽孢桿菌（C. diff）的病人。為防止病原體傳播，護理師執行哪項措施最為關鍵？
A nurse is caring for a client with Clostridium difficile infection. Which action is most essential for the nurse to perform to prevent the spread of the pathogen?
- AMaintain the client in a semi-private room將病人安置於半私人病房
- BPerform hand hygiene with an alcohol-based hand rub使用酒精性搓手液進行手部衛生
- CWash hands with soap and water after client contact✓ 正解接觸病人後用肥皂和水洗手
- DWear an N95 respirator when entering the room進入病房時佩戴 N95 呼吸器
困難梭狀芽孢桿菌（C. diff）會產生孢子，酒精類乾洗手液無法有效殺滅孢子。物理性的肥皂與流動清水洗手是移除孢子的唯一有效方式。此外，該病原體需採接觸隔離（Contact Precautions），應安置於單人房或同病種隔離。N95 用於空氣傳播隔離，與此無關。
Clostridium difficile produces spores, and alcohol-based hand rubs cannot effectively kill these spores. Mechanical handwashing with soap and running water is the only effective method for removing spores. In addition, this pathogen requires contact precautions, and the client should be placed in a private room or cohorted with others having the same pathogen. N95 respirators are used for airborne precautions and are not applicable here.
美國醫院對於 C. diff 感染嚴格執行肥皂洗手並有專門監查員；台灣臨床亦推廣洗手，但有時因環境限制較難完全落實單人房隔離。
