When is an N95 respirator required?

• A. For airborne infections such as TB when performing high-risk procedures.
• B. For all patients always.
• C. Only when cleaning rooms.
• D. Never.

Answer: (D)

N95 respirators are used when there is a risk of airborne transmission, especially during procedures that can aerosolize infectious material. This is why they’re required for infections like tuberculosis and for aerosol-generating procedures such as suctioning, intubation, or bronchoscopy. The respirator filters small particles from the air you breathe and must be properly fitted with a seal check to be effective. Use them as part of airborne precautions in the appropriate setting (often with a negative-pressure room if available) and follow the facility’s policy on fit testing and reuse.

They aren’t needed for every patient or routine tasks like cleaning; those activities follow standard precautions or other specific precautions based on the suspected or confirmed transmission route. Understanding when airborne precautions apply helps keep healthcare providers protected during high-risk situations.
