- AChlorhexidine gluconate葡萄糖酸氯己定
- BQuaternary ammonium compounds四級銨化合物
- CSodium hypochlorite (Bleach) solution✓ 正解次氯酸鈉（漂白水）溶液
- DAlcohol-based hand sanitizer酒精性乾洗手凝膠

困難梭狀桿菌（C. difficile）會產生具有高度抗藥性的芽孢（Spores），一般酒精性乾洗手液與常見的四級銨鹽消毒劑無法破壞這些芽孢。因此，照護 C. diff 病人時，手部清潔必須使用「肥皂與水」（Soap and water）進行物理性沖洗，設備與環境消毒則必須使用氯系消毒劑（漂白水，Sodium hypochlorite），以有效殺滅芽孢並防止交叉感染。
Clostridioides difficile forms spores that are resistant to alcohol and quaternary ammonium compounds. Sodium hypochlorite (bleach) is the most effective agent for disinfecting equipment and surfaces to eliminate these spores and prevent transmission.
