一位接受空氣傳播防護的疑似結核病病人，護理師進入病房時應穿戴什麼個人防護裝備？
A nurse is caring for a client on airborne precautions for suspected tuberculosis. Which personal protective equipment (PPE) should the nurse wear when entering the room?
- ASurgical mask外科口罩
- BSterile gloves無菌手套
- CFace shield面罩
- DN95 respirator✓ 正解N95 呼吸防護器
結核病（Tuberculosis, TB）透過空氣傳播（Airborne transmission），結核桿菌懸浮於空氣中微粒小於 5 微米，可長時間停留並遠距離傳播。護理師進入病房時，必須使用能過濾 95% 以上微粒的 N95 呼吸防護器（Respirator）以確保安全。外科口罩僅能阻擋飛沫，無法有效過濾此類微小懸浮粒子。臨床思路應遵守感染控制標準，確保防護設備與傳播路徑相符。
Tuberculosis is transmitted via airborne droplets smaller than 5 microns that remain suspended in the air, necessitating the use of an N95 respirator to filter these particles effectively. Surgical masks only block large droplets and do not provide adequate protection against airborne pathogens like Mycobacterium tuberculosis.
美國醫院對空氣傳播防護極為嚴格，N95 必須經過 Fit Testing（密合度測試）才能使用，且須確保在進入房間前已佩戴妥當。
