Which type of mask is required for droplet precautions within 3 feet of a patient?

In the context of droplet precautions, wearing a surgical mask is essential when a healthcare worker is within 3 feet of a patient. Surgical masks are designed to contain respiratory droplets that may be generated during talking, coughing, or sneezing, thereby protecting both the healthcare worker and the patient from potential transmission of infectious agents.

Surgical masks have a proper fit and filtration capacity that sufficiently block large droplets, which are the primary concern with droplet transmission. This makes them appropriate for situations like caring for patients with respiratory illnesses or during procedures that may generate respiratory droplets, as the mask serves as a barrier to reduce the spread of pathogens.

The other options do not provide the same level of protection or are not designed for this type of precaution. N95 respirators, for example, are intended for airborne precautions, where smaller particles are of concern, while cloth masks do not offer the same filtration efficiency and are generally not considered sufficient in clinical settings. A full-face respirator, while offering extensive protection, is not necessary for droplet precautions and is more suited for specific high-risk situations. Thus, a surgical mask is the most appropriate and effective choice for protection in the scenario described.
