Which of the Following Can Be Used to Reduce Microbes

Question

Which of the following can be used to reduce microbes in the air of a patient's room?
A) HEPA filters
B) ethylene oxide
C) ultraviolet light
D) both HEPA filters and ultraviolet light
E) both ethylene oxide and ultraviolet light

Accepted Answer

HEPA filters can capture and remove airborne particles, including microbes, while ultraviolet light can kill or inactivate microbes that are present in the air. Therefore, using both HEPA filters and ultraviolet light can effectively reduce the number of microbes in the air of a patient's room. Ethylene oxide, on the other hand, is a gas used for sterilization of medical equipment, and is not typically used to clean the air in a patient's room.
