An infant is admitted with a diagnosis of respiratory syncytial virus (RSV) infection. The type of transmission-based isolation precaution the nurse would set up would be:

A. Contact precautions: RSV is spread through direct contact with secretions, making contact precautions essential. B. Standard precautions: Always used for all patients to reduce risk of transmission of pathogens. C. Droplet precautions: RSV can also be transmitted via large respiratory droplets, so droplet precautions are appropriate. D. Airborne infection isolation precautions: RSV is not airborne; negative-pressure rooms and N95 masks are not required.
