A patient with confirmed multidrug-resistant tuberculosis requiring an immediate bronchoscopy should be performed in which type of room?

• A. Airborne infection isolation room (AIIR)
• B. Standard patient room
• C. Isolation room with positive pressure
• D. Private room with no special ventilation

Answer: (A)

When a patient with confirmed multidrug-resistant tuberculosis needs an aerosol-generating procedure, the room type must contain airborne pathogens. An airborne infection isolation room is designed with negative pressure, so air flows into the room from adjacent spaces and is exhausted outside the building, typically through filtration. This setup helps prevent infectious aerosols generated during bronchoscopy from escaping to other areas.

Using a standard patient room or a private room with no special ventilation would not reliably contain airborne particles, and a room with positive pressure could push contaminated air into surrounding areas, increasing transmission risk. Therefore, the best choice is the airborne infection isolation room to minimize exposure during the procedure.
