- AUsing soap and water✓ 正解使用肥皂和水
- BUsing a chlorhexidine gluconate wash使用葡萄糖酸氯己定清洗
- CUsing a povidone-iodine scrub使用聚維酮碘刷洗
- DUsing an alcohol-based hand sanitizer使用酒精性乾洗手液

難辨梭狀芽孢桿菌（Clostridioides difficile, C. diff）會產生芽孢（Spores），這種芽孢對酒精具有極強的抵抗力，一般的酒精性乾洗手（Alcohol-based hand sanitizer）無法將其殺滅或移除。因此，針對 C. diff 的感染控制，必須使用肥皂與水（Soap and water）進行濕式洗手，透過物理性的機械摩擦（Mechanical friction）將皮膚表面的芽孢沖洗乾淨，這是唯一符合循證護理的最佳實踐。
Soap and water must be used for hand hygiene when caring for clients with Clostridioides difficile because mechanical friction is required to physically remove spores. Alcohol-based sanitizers and other antiseptics are ineffective against C. difficile spores, making wet washing the only appropriate method for infection control.
