A nurse is caring for a patient who has influenza. What type of transmission-based precautions should the nurse implement for this patient?

Contact precautions

Droplet precautions

Airborne precautions

Neutropenic precautions

Answer and Explanation

The Correct Answer is B

Choice A reason: This is not the correct answer, as contact precautions are indicated for patients who have infections that can be spread by direct or indirect contact with the patient or their environment. Influenza is not spread by contact but by respiratory droplets.

Choice B reason: This is the correct answer, as droplet precautions are indicated for patients who have infections that can be spread by large droplets that are generated by coughing, sneezing, or talking and can be transmitted to others who are within 3 feet of the patient. Influenza is caused by a virus that can spread through respiratory droplets.

Choice C reason: This is not the correct answer, as airborne precautions are indicated for patients who have infections that can be spread by small droplets that remain in the air for long periods of time and can be inhaled by others. Influenza is not spread by airborne droplets, unless it is a novel strain that has the potential to cause a pandemic.

Choice D reason: This is not the correct answer, as neutropenic precautions are indicated for patients who have low white blood cell counts and are at risk of developing infections from normal flora or environmental sources. Influenza is not caused by normal flora or environmental sources, but by a virus that can infect the respiratory tract.

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. The child's immature immune system B. The child's exposure to other infected patients or health care workers C. The child's use of contaminated medical devices or equipment D. The child's contact with environmental surfaces or objects E. The child's history of community-acquired infections (CAIs)

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.
