A nurse is caring for a client on contact precautions. Which action is the most important to prevent the spread of infection?
- AHand hygiene after removing gloves✓ 正解脫下手套後執行手部衛生
- BUsing a private room使用單人病房

接觸防護（Contact Precautions）旨在預防經由直接或間接接觸傳播的病原體（如 MRSA、VRE、C. difficile）。根據 CDC 指引，手部衛生（Hand hygiene）是預防醫療照護相關感染（HAI）最有效、最根本的措施。儘管穿戴手套能阻隔接觸，但在脫除手套後，手部仍可能因穿戴過程中的微小破損或污染而沾染病原，因此必須立即洗手以切斷傳播鏈。其他選項雖為輔助預防措施，但手部衛生在感染控制的權重中始終位居第一。
Contact precautions are intended to prevent pathogens that are transmitted through direct or indirect contact (such as MRSA, VRE, and C. difficile). According to CDC guidelines, hand hygiene is the most effective and fundamental measure for preventing healthcare-associated infections (HAIs). Although gloves create a barrier to contact, the hands may still be contaminated through microscopic breaches or contamination during glove use, so handwashing immediately after glove removal is essential to break the chain of transmission. Other options are supportive measures, but in infection control, hand hygiene always carries the greatest weight.
