Which precautions are used to prevent airborne transmission?

• A. Contact precautions: gloves and gown
• B. Droplet precautions: surgical mask within 3 feet
• C. Airborne precautions: negative pressure room, N95 respirator
• D. Standard precautions: hand hygiene only

Answer: (C)

Airborne transmission involves tiny particles that can linger in the air and travel beyond immediate contact. To prevent this, use airborne precautions: place the patient in a negative‑pressure room so contaminated air is directed outside the room and not into the rest of the facility, and ensure staff wear a properly fitted N95 respirator to filter out the small aerosolized particles. Gloves and gown address contact transmission, not airborne. A surgical mask within about 3 feet targets larger droplets, not aerosols that stay suspended. Standard precautions cover basic hygiene and barrier techniques but don’t specifically control airborne spread.
