Question

q21. what should healthcare personnel wear when caring for patients in droplet precautions?
an apron
a head cap
a mask
goggles

Explanation:

Droplet precautions are used to prevent the spread of diseases that are transmitted by large-particle droplets (e.g., influenza). A mask is essential as it helps block the inhalation of these droplets. An apron is more for protecting clothing from body fluids (not specific to droplet precautions). A head cap is mainly for maintaining a sterile environment in some surgical or clean - room settings (not directly related to droplet precautions). Goggles protect the eyes from splashes (more relevant in contact precautions with potential splashes rather than just droplet spread).

Answer:

C. A mask
