A charge nurse is observing a staff nurse who is caring for a child who has pertussis. Which of the following actions by the staff nurse indicates an understanding of infection control practices?

A. Follows airborne precautions by wearing an N95 respirator while caring for the child: Pertussis requires droplet precautions, not airborne precautions. An N95 respirator is not necessary.B. Maintains droplet precautions while the child is coughing and sneezing: Correct. Droplet precautions are appropriate for pertussis, which is spread through respiratory droplets. These precautions help prevent the transmission of the infection.C. Wears gloves when assisting the child to the bathroom: While wearing gloves is a standard precaution, it does not specifically address the droplet transmission route of pertussis. Gloves alone are not sufficient for preventing the spread of pertussis.D. Applies a face mask after entering the child's room: The face mask should be applied before entering the room to ensure the nurse is protected from respiratory droplets immediately upon entry.
