護理師正在收納一位疑似困難梭狀芽孢桿菌（C. diff）感染的病人。護理師應採取哪種類型的隔離預防措施？

困難梭狀芽孢桿菌（C. diff）是一種極具傳染性的病原體，常見於使用抗生素後的病人。其芽孢（spores）在環境中具有極強的抵抗力，一般的酒精性乾洗手無法有效殺滅，必須透過肥皂與水洗手才能將其移除。因此，針對此類感染，必須啟動接觸隔離（Contact Precautions），包括穿戴手套與隔離衣，以阻斷傳播鏈。

Clostridium difficile (C. diff) is a highly contagious pathogen, commonly seen in patients after antibiotic use. Its spores are highly resistant in the environment, and ordinary alcohol-based hand sanitizers cannot effectively destroy them; they must be removed by washing the hands with soap and water. Therefore, for such infections, Contact Precautions must be initiated, including the wearing of gloves and gowns, in order to break the chain of transmission.

台灣與美國在 C. diff 的手部衛生規定上一致，均特別強調「務必使用肥皂與水洗手」，而非僅依賴酒精性乾洗手，因為酒精對芽孢無效。此為 NCLEX 考試中關於感染控制的常考題。
