What is the role of HEPA masks for healthcare workers caring for pneumonia patients?

• A. To protect from skin contact
• B. To prevent hand contamination
• C. To filter airborne particles and protect workers
• D. To reduce fever

Answer: (C)

HEPA masks protect healthcare workers by filtering airborne particles, reducing inhalation of infectious aerosols. In caring for pneumonia patients, the air can carry tiny particles during coughing, suctioning, or other aerosol-generating procedures, so a tight-fitting respirator helps shield the wearer from inhaling these pathogens. This protection targets inhalation of airborne agents, not skin contact or hand contamination, and it does not affect fever. Use of these masks is appropriate during aerosol-generating situations or when airborne precautions are indicated, and they require proper fit-testing and use alongside other personal protective equipment.
