護理師照顧一位困難梭菌（C. diff）感染的病人，下列哪些是護理師照護計畫中預防傳播的必要組成部分？（選所有適合的）
A nurse is caring for a client with Clostridium difficile (C. diff). Which of the following are essential components of the nurse's plan of care to prevent transmission? (Select all that apply.)
- AImplement Contact Precautions.✓ 正解實施接觸隔離
- BWash hands with soap and water after patient contact.✓ 正解接觸病人後用肥皂和水洗手
- CUse alcohol-based hand sanitizer before entering the room.進入房間前使用酒精性乾洗手
- DEnsure visitors wear gowns and gloves.✓ 正解確保訪客穿著隔離衣和手套
- EClean the client's room with bleach-based disinfectant.✓ 正解使用含氯消毒劑清潔病人房間
C. diff 感染需採接觸隔離，病人應單獨或與同類病人同室；照護者應在接觸病人後徹底水洗手，因酒精無法殺死孢子。訪客需穿戴隔離衣和手套，並於離開病房後洗手。病房環境（特別是馬桶、門把）應使用含氯漂白劑清潔。
C. difficile infection requires contact precautions, and the client should be placed in a private room or cohorted with other C. diff clients. Caregivers must wash hands thoroughly with soap and water after patient contact, because alcohol-based hand sanitizers do not kill the spores. Visitors must wear gowns and gloves and wash their hands after leaving the room. The room environment (especially toilets and door handles) should be cleaned with a bleach-based disinfectant.
兩地均要求 C. diff 採接觸隔離與水洗手；美國可能更強調病房環境的消毒標準；台灣則可能較依賴感控師的指導。
