In airborne precautions, which environmental controls are recommended?

• A. Standard precautions with no special room
• B. Positive-pressure room with standard filtration
• C. N95 respirator, negative-pressure room, and HEPA filtration
• D. Surgical mask for all patients only

Answer: (C)

Airborne precautions rely on containing infectious aerosols and protecting healthcare workers from inhalation. A negative-pressure isolation room keeps contaminated air from flowing into other parts of the facility, with ventilation designed to pull air outward from the room and away from staff areas. Wearing an N95 respirator or higher by anyone entering the room provides a tight seal that filters out tiny particles that could contain the pathogen. Including filtration like HEPA helps remove remaining airborne contaminants from the room air, further reducing the risk of transmission. Standard precautions without a special room don’t stop aerosol spread, and a positive-pressure room would push air from the room into surrounding areas, potentially spreading infection. Relying on a surgical mask for patients alone doesn’t protect staff from inhaling aerosols. So combining a negative-pressure room, appropriate respirators for staff, and filtration aligns with how airborne pathogens are controlled in the environment.
