A nurse is caring for a client on contact precautions for MRSA. Which action is the most critical for the nurse to perform when leaving the room?
- APerforming hand hygiene immediately after removing PPE✓ 正解脫除個人防護裝備（PPE）後立即執行手部衛生
- BDiscarding gloves inside the room在病室內丟棄手套

MRSA（耐藥性金黃色葡萄球菌）病患採取接觸隔離（Contact Precautions）。這類病原體主要透過直接接觸或間接接觸污染表面傳播。離開病室時，脫除 PPE 的順序與手部衛生是防止病原體帶出的關鍵。手部衛生（Hand hygiene）被認為是阻斷交叉感染最關鍵的一步，因為即使正確脫除 PPE，手上仍可能沾染微生物，必須徹底清潔。
Patients with MRSA (methicillin-resistant Staphylococcus aureus) require contact precautions. This pathogen is primarily transmitted through direct or indirect contact with contaminated surfaces. When leaving the patient's room, the order of removing PPE and performing hand hygiene is key to preventing transfer of the pathogen. Hand hygiene is regarded as the most critical step in interrupting cross-infection, because even after PPE is properly removed, the hands may still carry microorganisms and must be thoroughly cleaned.
