A nurse is teaching a class about infection control to a group of nurses. The nurse should identify which of the following diseases as requiring the implementation of droplet precautions?

A. Rubeola (measles). Rubeola is transmitted through airborne particles and requires airborne precautions, including the use of an N95 respirator and placement in a negative pressure room. Droplet precautions would not provide sufficient protection due to the small particle size and long-range transmission. B. Varicella (chickenpox). Varicella requires both airborne and contact precautions because it spreads via airborne respiratory droplets and direct contact with lesions. A client with varicella must be isolated in a negative pressure room and healthcare workers should use full PPE. C. Tuberculosis. Tuberculosis is caused by Mycobacterium tuberculosis and is spread through airborne droplet nuclei, which remain suspended in the air for extended periods. It requires airborne precautions, including an N95 respirator and isolation in a specialized room. D. Pertussis (whooping cough). Pertussis is a highly contagious bacterial infection that spreads through large respiratory droplets during coughing or sneezing. Droplet precautions are required, which include wearing a surgical mask when within 3 feet of the client and practicing proper hand hygiene to prevent transmission.
