A resident with active pulmonary tuberculosis requires:
a.Contact precautions: gown and gloves for every room entry, dedicated equipment, door may stay open
b.Standard precautions only: hand hygiene and gloves when body-fluid contact is likely
c.Droplet precautions: surgical mask within six feet, private room, door may stay open
d.Airborne precautions: AIIR (negative-pressure room), N95 or PAPR for staff, door kept closed

TB is transmitted by airborne droplet nuclei. CDC requires Airborne Infection Isolation Room (negative pressure with at least 6 air changes/hour, exhausted outdoors or through HEPA), N95 respirator (fit-tested) or PAPR for staff, and door kept closed. Standard (b), contact (a), or droplet precautions (c) are insufficient and risk staff and other-resident infection. The resident wears a surgical mask if transported.
