What diagnoses fall under droplet precautions?

Droplet precautions are implemented to prevent the spread of infectious agents that are transmitted through respiratory droplets. These droplets can be generated when an infected person coughs, sneezes, talks, or breathes, and they can travel a short distance before settling on surfaces or being inhaled by someone nearby.

The correct answer identifies influenza, rubella, and mumps as conditions that require droplet precautions. Influenza is a viral respiratory illness known for its ability to spread via large respiratory droplets. Rubella, also known as German measles, is similarly transmitted through respiratory droplets and poses significant risk during pregnancy due to its potential to cause congenital defects. Mumps is another viral illness spread through droplets, primarily affecting the salivary glands but also creating respiratory transmission risk.

Other options present conditions that do not fall under droplet precautions. For instance, measles is associated with airborne transmission rather than droplet precautions, and tuberculosis is primarily spread through airborne particles, necessitating a different level of isolation. C. difficile and E. coli infections are typically related to contact precautions, not droplet. Hepatitis A is primarily transmitted through the fecal-oral route, and chickenpox requires airborne precautions due to the ability of its virus to remain in the air
