You are caring for a patient with Tuberculosis on Airborne Precautions. What PPE must you wear when entering the room?

• A. N95 Respirator Mask
• B. Surgical Mask
• C. Face Shield
• D. Gown

Answer: (A)

Tuberculosis spreads through tiny airborne particles, so protection must filter inhaled air rather than just block larger droplets. A properly fitted N95 respirator is designed to seal to the face and filter out at least 95% of these airborne particles, making it the correct choice for entering a room with airborne precautions for TB. A surgical mask doesn’t seal or filter aerosols well enough, so it won’t provide adequate protection. A face shield protects eyes but doesn’t prevent inhalation of particles, and a gown is for preventing contamination from contact with surfaces or fluids, not for airborne risk. So, before you enter, put on a properly fitted N95 respirator, ensuring a good seal, and follow your facility’s donning and doffing procedures. Additional PPE like eye protection or a gown may be added if there are other risks, but the essential safeguard for TB airborne precautions is the N95 respirator.
