A nurse is caring for a client with active tuberculosis (TB). Which intervention is essential when entering the client's room?
- APerform routine hand hygiene only僅執行常規手部衛生
- BWear an N95 respirator✓ 正解佩戴 N95 呼吸器
- CDon a disposable gown穿一次性隔離衣

肺結核（Tuberculosis, TB）透過空氣微粒（Airborne particles）傳播。針對活動性肺結核病人，標準隔離防護為空氣隔離（Airborne Precautions）。空氣微粒極小且能長時間懸浮，外科口罩無法過濾此類顆粒，因此護理師進入病室時必須佩戴經密合度測試（Fit test）合格的 N95 口罩，以提供有效的呼吸道保護。
Tuberculosis (TB) is transmitted via airborne particles. For clients with active pulmonary tuberculosis, standard isolation precautions are Airborne Precautions. The droplet nuclei are very small and can remain suspended in air for long periods; a surgical mask cannot filter such particles. The nurse must therefore wear a fit-tested N95 respirator when entering the client's room to provide effective respiratory protection.
