A nurse is admitting a child who has pertussis. Which of the following isolation precautions should the nurse initiate?

A. Droplet Pertussis (whooping cough) is transmitted via respiratory droplets. Droplet precautions (mask, private room if possible) are essential to prevent spread. B. Contact Contact precautions are for pathogens spread via direct touch (e.g., C. difficile, RSV), not primarily droplet-borne infections like pertussis. C. Airborne Airborne precautions are for diseases like tuberculosis, measles, and varicella. Pertussis does not require negative pressure rooms. D. Protective environment This is for immunocompromised clients (e.g., stem cell transplant patients) to protect them from pathogens-not to prevent them from infecting others.
