Question

a n - 95 respirator or more powerful filtering mask such as a high efficiency particulate air (hepa) mask must be worn for ______________.
standard precautions
contact precautions
airborne precautions
droplet precautions

Explanation:

Airborne precautions are used for diseases that spread via small particles (aerosols) that can remain in the air for long periods. N - 95 respirators and HEPA masks are designed to filter out these small particles. Standard precautions are general infection - control measures. Contact precautions are for diseases spread by direct or indirect contact. Droplet precautions are for diseases spread by larger respiratory droplets (which do not remain in the air as long as aerosols), and a regular surgical mask is often sufficient for droplet precautions.

Answer:

Airborne Precautions
