Which transmission-based precaution is mandatory when caring for an inpatient diagnosed with open pulmonary tuberculosis?
Answer and explanation
Correct answer: A. Airborne precautions with an N95 respirator in a negative pressure isolation room
Answer: Airborne precautions with an N95 respirator in a negative pressure isolation room.
Why not the others: Mycobacterium tuberculosis is transmitted via droplet nuclei (<5 microns) that remain suspended in air, requiring negative-pressure airborne infection isolation and N95 masks; Simple surgical masks do not filter droplet nuclei; Positive pressure rooms blow infectious air out into hospital corridors.
