Practice Question
The nurse is working on an infectious disease unit. Which client should be assigned to a room with negative airflow, while requiring personnel to use a particulate respirator mask, and requiring staff to observe airborne, as well as standard precautions?
Answer Choices:
Correct Answer:
A client with a positive Mantoux and sputum cultures results positive for acid-fast bacillus (AFB).
Rationale:
🔶 AFB-positive tuberculosis (TB) is spread via airborne particles, requiring strict airborne isolation in a negative airflow room.
🔶 Particulate respirator masks (like N95) are essential to protect staff from inhaling Mycobacterium tuberculosis.
🔶 This client poses the highest transmission risk and must be managed with both airborne and standard precautions.
🔶 Failure to isolate appropriately can result in rapid nosocomial spread of TB.
🔶 TB is one of the few conditions mandating airborne precautions at all times during hospitalization.
