A nurse is teaching about hand hygiene using alcohol-based rubs. Which points should be included? (Select all that apply.)
- AUse enough product to cover all surfaces of the hands✓ 正解使用足夠的產品覆蓋手部所有表面
- BRub hands until dry, which takes about 20 seconds✓ 正解搓揉雙手直至乾燥，約需 20 秒
- CWash hands with soap and water if hands are visibly soiled✓ 正解若手部明顯髒污，應使用肥皂和水洗手
- DPerform hand hygiene after touching the patient's bedside table✓ 正解接觸病人床邊桌後執行手部衛生
- EAlcohol-based rub is the preferred method for C. difficile infections酒精性乾洗手是 C. difficile 感染的首選方法
手部衛生是感染控制的關鍵。酒精乾洗手液需覆蓋手部所有表面並摩擦至乾燥（約 20 秒）才具殺菌效果。若手部可見髒污或被生物物質污染，必須使用肥皂水洗手，因為酒精無法移除有機物質。接觸病人周遭環境亦會帶菌，需執行手部衛生。困難梭狀桿菌（C. difficile）會產生芽孢，酒精無法殺死，必須使用肥皂水機械性洗手。
Hand hygiene is key to infection control. Alcohol-based hand rubs must cover all hand surfaces and be rubbed until dry (about 20 seconds) to be bactericidal. If the hands are visibly soiled or contaminated with biological material, soap and water must be used, because alcohol cannot remove organic matter. The patient's surrounding environment also carries pathogens, so hand hygiene must be performed after contact. Clostridioides difficile (C. difficile) produces spores that alcohol cannot kill, so soap and water with mechanical washing is required.
