OSMT (Ontario Society of Medical Technologists) Practice Exam

Question: 1 / 400

Ultraviolet radiation is ideal for:

a. sterilizing benches

b. sterilizing instruments

c. sterilizing liquids

d. killing airborne bacteria

Ultraviolet (UV) radiation is particularly effective at killing airborne bacteria due to its ability to disrupt the DNA or RNA of microorganisms. This disruption prevents reproduction and leads to cell death, making UV light a powerful tool for disinfection in environments where airborne pathogens can pose significant health risks.

While UV light can be used for a variety of sterilization purposes, it is specifically suited for eliminating bacteria in the air, which is critical in healthcare settings where the prevention of airborne transmission of infections is paramount. Other items or surfaces, such as benches or instruments, typically require additional methods for effective sterilization or disinfection, as UV light may not penetrate surfaces or liquids effectively to achieve desired sterilization levels.
