A nurse is caring for a toddler who has varicella zoster. Which of the following actions should the nurse take?

A. Wear a mask while in the room with the toddler: Varicella (chickenpox) is transmitted via airborne and contact routes. Standard precautions include contact and airborne precautions, so an N95 or fitted mask is required rather than a simple mask. B. Wipe the stethoscope with an alcohol-based gel after use: Cleaning equipment that comes into contact with the client helps prevent the spread of infection. Alcohol-based disinfectants effectively reduce transmission of varicella from shared medical equipment. C. Place the toddler in a room with positive-pressure airflow: Positive-pressure rooms are used for immunocompromised clients to prevent pathogens from entering. Airborne precautions for varicella require a negative-pressure room to prevent spreading the virus to others. D. Schedule the toddler for private time in the playroom: Allowing a child with varicella in communal areas risks spreading the virus to susceptible children. The toddler should remain in isolation until lesions crust over.
