Which statement best describes respiratory isolation?

Which statement best describes respiratory isolation?

• A. Prevents spread of infectious agents in aerosol form
• B. Prevents spread via contact with surfaces
• C. Protects from airborne but not aerosolized agents
• D. Does not relate to infection control

Answer: (A)

Respiratory isolation is concerned with preventing the spread of infectious agents through the air. The best description is that it prevents spread of infectious agents in aerosol form. Aerosolized particles can remain suspended in the air and travel with air currents, potentially being inhaled by others, so measures like masks or respirators and controlled ventilation are used to stop this transmission. It isn’t about spreading via surfaces (that’s contact precautions), and it doesn’t make sense to say it protects from airborne but not aerosolized agents. It directly relates to infection control.
