Which term means moved by or through air?

• A. Airborne pathogens
• B. Airborne
• C. Anteroom
• D. Asbestos

Answer: (B)

The concept being tested is describing how something moves in the environment. Airborne means moved by or through air; it’s the standard term used to indicate that substances can travel on air currents and remain suspended, potentially being inhaled at a distance. In infection control, identifying something as airborne helps determine the precautions needed, since these agents can spread beyond close contact through the air. The other options don’t fit as a transport description: anteroom is just a doorway area between spaces, not a mode of movement; asbestos is a hazardous material and not a transport term, and while asbestos fibers can become airborne when disturbed, that doesn’t define the term itself; “airborne pathogens” is a phrase describing pathogens moved by air, but the general term for the mode is simply airborne.
