Which precaution requires an N95 respirator for TB measles and varicella?

Explanation:
Airborne precautions protect against infections that travel in tiny aerosol particles that can linger in the air. TB spreads through inhaled airborne nuclei, and measles and varicella can also spread via the air, especially with aerosol-generating activities. Because these pathogens require protection against inhaled particles, an N95 respirator is used to filter the air the wearer breathes. In practice, airborne precautions include the respirator, a negative-pressure room if possible, and proper entry procedures. Standard precautions cover basic hygiene for all patients, droplet precautions use a surgical mask for larger droplets, and contact precautions focus on gloves and gowns for touching contaminated surfaces or skin; none of these require an N95 for inhalation protection.
