A nurse is planning care for a toddler who has measles. Which of the following isolation precautions should the nurse initiate?

Rationale A. Contact: Contact precautions are used for infections spread by direct or indirect contact, such as C. difficile or MRSA. Measles is not primarily transmitted via contact, so contact precautions alone are insufficient. B. Airborne: Measles is highly contagious and transmitted via airborne respiratory droplets that can remain suspended in the air. Airborne precautions, including placing the client in a negative-pressure room and requiring staff to wear N95 respirators, are necessary to prevent transmission. C. Protective: Protective (or neutropenic) precautions are designed to protect immunocompromised clients from infection. They are not appropriate for preventing the spread of measles from an infected client. D. Droplet: Droplet precautions are used for infections spread by larger respiratory droplets, such as influenza or pertussis. Measles requires airborne precautions because the virus can travel on smaller particles and remain suspended in the air for extended periods.
