A nurse in a pediatric unit is caring for a group of clients. For which of the following diseases should the nurse implement droplet precautions?

A. Varicella zoster: Varicella (chickenpox) is transmitted via airborne and contact routes. Airborne precautions with a negative-pressure room are required, not droplet precautions. B. Vancomycin-resistant enterococcus (VRE): VRE is primarily spread via contact with contaminated surfaces or hands. Contact precautions are indicated, rather than droplet precautions. C. Pertussis: Pertussis (whooping cough) is transmitted via respiratory droplets. Droplet precautions, including a mask for close contact, are essential to prevent spread to healthcare personnel and other clients. D. Rotavirus: Rotavirus is transmitted primarily via the fecal-oral route. Contact precautions are necessary to prevent spread, not droplet precautions.
