If you suspect tuberculosis in your patient, what personal protective equipment is essential?

• A. Surgical mask
• B. N-95 mask
• C. Face shield
• D. Gloves

Answer: (B)

When suspecting tuberculosis (TB) in a patient, the use of an N-95 mask is essential due to the airborne nature of the disease. TB is transmitted through droplet nuclei that can linger in the air, and these small particles can be inhaled by individuals nearby. An N-95 mask is designed to filter out at least 95% of airborne particles, thus offering better protection against these smaller infectious agents compared to surgical masks.

Surgical masks primarily protect against large droplets and do not adequately filter out the small particles that may contain infectious pathogens like TB. Meanwhile, while face shields and gloves are important pieces of personal protective equipment in various situations, they do not provide the necessary respiratory protection required when in the presence of a patient suspected of having an airborne infection. Therefore, the N-95 mask is the vital piece of equipment to prevent inhalation of TB bacteria and ensure the safety of the healthcare provider.
