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?

Infectious agent

Reservoir

Portal of exit

Mode of transmission

Answer and Explanation

The Correct Answer is A

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.

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

Explanation

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.

A. Wash hands with soap and water or use alcohol-based hand rub before and after patient contact. B. Wear gloves, gowns, masks, eye protection, or face shields as appropriate to prevent exposure to blood or body fluids. C. Cover mouth and nose with a tissue or elbow when coughing or sneezing, and dispose of tissues properly. D. Assign patients to private rooms if possible or cohort them with other patients with the same infection. E. Clean and disinfect frequently touched surfaces and equipment with appropriate agents.

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

Explanation

Choice A reason: This action should be taken as part of standard precautions, as it helps prevent the transmission of microorganisms through hand contact.

Choice B reason: This action should be taken as part of standard precautions, as it helps prevent the transmission of microorganisms through exposure to blood or body fluids.

Choice C reason: This action should be taken as part of standard precautions, as it helps prevent the transmission of microorganisms through respiratory droplets.

Choice D reason: This action is not part of standard precautions, but rather part of transmission-based precautions. It helps prevent the transmission of microorganisms through direct or indirect contact, airborne, or droplet routes.

Choice E reason: This action should be taken as part of standard precautions, as it helps prevent the transmission of microorganisms through environmental surfaces or objects.
