What is the primary purpose of wearing an N95 mask?

Protection against contact diseases
Protection against airborne diseases
Protection against surgical smoke
Protection against bloodborne pathogens

The correct answer is: Protection against airborne diseases

The primary purpose of wearing an N95 mask is to provide protection against airborne diseases. N95 respirators are specifically designed to filter out at least 95% of very small particles, including those that are airborne and may contain infectious agents such as viruses and bacteria. The mask's close fit increases its efficiency in preventing inhalation of these harmful pathogens, making it a critical component of personal protective equipment in healthcare settings. Unlike other forms of personal protective equipment that may protect against contact or fluid exposure, the N95 mask is particularly focused on the filtration of air, which is vital when working with patients who may have respiratory infections. This makes it an essential tool for healthcare professionals, especially in environments where airborne transmission is a risk, such as during aerosol-generating procedures.
