Which transmission of organisms is not prevented by the nurse performing hand hygiene?
1. Vehicle-borne transmission
2. Vector-borne transmission
3. Indirect contact transmission
4. Direct contact transmission
Correct Answer: 2
Vector-borne transmission of organisms pertains to an animal or insect that serves as an immediate means of transporting the infectious agent, and so could not be prevented by hand hygiene. Vehicle-borne transmission pertains to any substance that transfers infectious agents to a susceptible host, such as the nurse's hands. Vehicle-borne transmission is a form of indirect contact transmission. Direct contact transmission is transmission of a microorganism through touching, kissing, or any form of direct contact, such as the nurse touching the client who is susceptible to infection.
