護理師照護一位疑似肺結核且需採取空氣傳播預防措施的病人，應優先使用哪種個人防護設備？
A nurse is caring for a client on airborne precautions for suspected tuberculosis. Which personal protective equipment (PPE) should the nurse prioritize?
- ASurgical mask外科口罩
- BSterile gloves無菌手套
- CFace shield面罩
- DN95 respirator✓ 正解N95 呼吸防護具
肺結核（Tuberculosis, TB）透過空氣傳播，病原體微粒（Droplet Nuclei）極小，可長時間懸浮於空氣中。N95 口罩（N95 Respirator）具有過濾 95% 以上微米級微粒的能力，能有效阻隔 TB 菌。護理師在進入疑似 TB 病人的負壓隔離病房前，必須確保 N95 口罩密合度（Fit Test），以確保防護有效性。
Tuberculosis (TB) is transmitted through the air, and the pathogen-carrying droplet nuclei are extremely small and can remain suspended in the air for long periods of time. The N95 respirator is capable of filtering more than 95% of micron-sized particles and can effectively block TB bacilli. Before entering a negative pressure isolation room for a suspected TB patient, the nurse must ensure the N95 mask has been fit-tested in order to confirm effective protection.
