Infection Control ( 13 Questions)
A nurse is teaching a group of parents about the chain of infection and how to prevent it. The nurse should explain that the first link in the chain of infection is which of the following?
Choice A reason: This is the correct answer, as the infectious agent is the microorganism that causes the infection, such as bacteria, viruses, fungi, or parasites.
Choice B reason: This is not the correct answer, as the reservoir is the second link in the chain of infection. It is the place where the infectious agent lives and grows, such as humans, animals, plants, soil, or water.
Choice C reason: This is not the correct answer, as the portal of exit is the third link in the chain of infection. It is the way that the infectious agent leaves the reservoir, such as through body fluids, skin, mucous membranes, or respiratory tract.
Choice D reason: This is not the correct answer, as the mode of transmission is the fourth link in the chain of infection. It is the way that the infectious agent travels from one host to another, such as through direct or indirect contact, droplet, airborne, vector, or vehicle transmission.
