護理師準備進入一名診斷為肺結核（TB）病人的房間。護理師必須穿戴哪種個人防護裝備（PPE）？
A nurse is preparing to enter the room of a client diagnosed with pulmonary tuberculosis (TB). Which personal protective equipment (PPE) is essential for the nurse to wear?
- AN95 respirator✓ 正解N95 呼吸器
- BGown and gloves隔離衣與手套
- CFace shield面罩
- DSurgical mask外科口罩
肺結核經由空氣傳播，病原體微粒小於 5 微米，可懸浮於空氣中。處理空氣傳播疾病時，醫護人員必須佩戴經過密合度測試的 N95 呼吸器。外科口罩（D）僅能阻隔飛沫；手套與隔離衣（B）用於接觸隔離；面罩（C）用於預防噴濺，皆非空氣隔離的首要核心裝備。
Pulmonary tuberculosis is transmitted via airborne droplet nuclei smaller than 5 micrometers, which can remain suspended in the air. When caring for clients with airborne-transmitted diseases, healthcare workers must wear a fit-tested N95 respirator. A surgical mask (D) only blocks droplets; gowns and gloves (B) are used for contact precautions; a face shield (C) prevents splashes; none of these are the primary essential equipment for airborne isolation.
美國 NCLEX 強調 N95 必須經過 Fit Testing；台灣臨床雖也要求，但在資源短缺時常以一般外科口罩外加 N95 替代（非標準做法）。
