為預防困難梭狀芽孢桿菌(C. difficile)在單位內擴散,護理師應優先執行哪項措施?

Which action should the nurse prioritize to prevent the spread of Clostridioides difficile in a hospital unit?

  • AWash hands with soap and water after patient care✓ 正解
    在病患照護後以肥皂和水洗手
  • BUse alcohol-based hand sanitizer after patient contact
    在接觸病患後使用酒精性乾洗手
  • CApply sterile gloves before physical examination
    在進行身體檢查前戴上無菌手套
  • DWear a N95 respirator when entering the room
    進入房間時佩戴 N95 呼吸器
Explanation · 中文詳解

困難梭狀芽孢桿菌(C. difficile)具有極強的環境抵抗力,因其會產生芽孢(Spore)。酒精乾洗手液無法殺滅芽孢,反而可能透過物理摩擦將芽孢散佈至周遭環境。根據 CDC 與感染控制規範,接觸此類病人必須執行「接觸隔離(Contact Precautions)」,並堅持使用肥皂與清水洗手,以機械性方式移除芽孢。

Hand washing with soap and water is the priority intervention to prevent the spread of Clostridioides difficile because mechanical friction effectively removes spores from the skin. Alcohol-based sanitizers are ineffective against C. difficile spores, and contact precautions, not airborne precautions, are required for this pathogen.

✦ 台美臨床差異

台美臨床在病房清潔與洗手政策上一致,皆嚴格要求針對 C. diff 病人使用肥皂洗手。不同之處在於,美國護理師在執行此類隔離時,更依賴單位內嚴格的「雙人核對與環境消毒追蹤系統」。
