A nurse is caring for a child who has a health care-associated infection (HAI). What factors may have contributed to the development of this type of infection? (Select all that apply.)

The child's immature immune system

The child's exposure to other infected patients or health care workers

The child's use of contaminated medical devices or equipment

The child's contact with environmental surfaces or objects

The child's history of community-acquired infections (CAIs)

Answer and Explanation

Correct Answer : A,B,C,D

Choice A reason: This factor may have contributed to the development of an HAI, as children have immature immune systems that make them more susceptible to infections.

Choice B reason: This factor may have contributed to the development of an HAI, as children may be exposed to other infected patients or health care workers who can transmit microorganisms through direct or indirect contact.

Choice C reason: This factor may have contributed to the development of an HAI, as children may use contaminated medical devices or equipment that can introduce microorganisms into their body, such as catheters, ventilators, or intravenous lines.

Choice D reason: This factor may have contributed to the development of an HAI, as children may contact environmental surfaces or objects that can harbor microorganisms, such as bed rails, tables, toys, or books.

Choice E reason: This factor may not have contributed to the development of an HAI, as CAIs are infections that are acquired outside of health care settings. However, CAIs may increase the risk of HAIs if they are not treated properly or if they cause complications.

Correct Answer is A

Explanation

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.

A. "You should ask the health care workers to wash their hands or use hand sanitizer before and after touching you or your equipment." B. "You should avoid touching your eyes, nose, or mouth with unwashed hands." C. "You should keep your room clean and tidy and dispose of any waste properly." D. "You should report any signs of infection, such as fever, redness, swelling, or pus, to your health care team." E. "You should limit the number of visitors and ask them to wear masks and gloves when they enter your room."

Correct Answer is ["A","B","D","E"]

Explanation

Choice A reason: This statement by the nurse would be appropriate to include in the teaching, as it helps prevent the transmission of microorganisms through hand contact between the health care workers and the patient or their equipment.

Choice B reason: This statement by the nurse would be appropriate to include in the teaching, as it helps prevent the transmission of microorganisms through self-inoculation of the mucous membranes with unwashed hands.

Choice C reason: This statement by the nurse may not be appropriate to include in the teaching, as it may not be feasible or realistic for the patient or family to keep their room clean and tidy and dispose of any waste properly. This may be more of a responsibility of the environmental services staff.

Choice D reason: This statement by the nurse would be appropriate to include in the teaching, as it helps detect and treat any HAIs early and prevent complications or spread of infection.

Choice E reason: This statement by the nurse would be appropriate to include in the teaching, as it helps reduce the exposure of the patient to potential sources of infection from visitors and protect them from transmitting any infection to others.
