Droplet precautions require

Correct option is A

Ans (a)
Sol. (a) Use of a surgical mask when within three feet of the patient
Explanation:
· Droplet precautions are used to prevent the spread of infections that are transmitted through respiratory droplets (e.g., influenza, COVID-19). The key measure is the use of a surgical mask when within three feet of the patient to prevent the transmission of droplets.
· Special air handling and ventilation systems (Option b) are more commonly associated with airborne precautions, not droplet precautions.
· Gloves and gowns (Option c) are standard precautions in many situations, but droplet precautions specifically emphasize the use of a mask.
· Strict isolation (Option d) in a private room is not specifically required for droplet precautions unless the patient is in a critical condition or the infection is highly contagious.
