A nurse is cleaning a child's room after discharge. The child had an infection that required contact precautions. Which of the following actions should the nurse take to prevent environmental contamination?

Wear gloves and a gown while handling the soiled linens and dispose of them in a biohazard bag.

Wear a mask and eye protection while wiping the surfaces and equipment with a disinfectant solution.

Wear sterile gloves and a surgical mask while removing any sharps or needles and place them in a puncture-resistant container.

Wear a respirator and a face shield while spraying an aerosol sanitizer in the air and on the curtains.

Answer and Explanation

The Correct Answer is A

Choice A reason: Wearing gloves and a gown while handling the soiled linens and disposing of them in a biohazard bag is an appropriate action to prevent environmental contamination. This follows the standard precautions for contact with blood or body fluids and the transmission-based precautions for contact with infectious agents.

Choice B reason: Wearing a mask and eye protection while wiping the surfaces and equipment with a disinfectant solution is not necessary for contact precautions. This would be indicated for droplet or airborne precautions, where respiratory droplets or particles may be present.

Choice C reason: Wearing sterile gloves and a surgical mask while removing any sharps or needles and placing them in a puncture-resistant container is not required for contact precautions. This would be indicated for situations where there is a risk of exposure to bloodborne pathogens or other infectious materials.

Choice D reason: Wearing a respirator and a face shield while spraying an aerosol sanitizer in the air and on the curtains is not recommended for contact precautions. This would be indicated for airborne precautions, where small airborne particles may be present. However, spraying an aerosol sanitizer is not an effective way to disinfect the environment, as it may create aerosols that can spread infection.

Correct Answer is C

Explanation

Choice A reason: This is a correct statement. The infectious agent is the microorganism that causes the disease, such as bacteria, viruses, fungi, or parasites.

Choice B reason: This is a correct statement. The reservoir is where the microorganism lives and grows, such as humans, animals, plants, soil, or water.

Choice C reason: This is an incorrect statement. The portal of exit is how the microorganism leaves the body of the reservoir, not how it enters the body of the host. The portal of entry is how the microorganism enters the body of the host.

Choice D reason: This is a correct statement. The susceptible host is someone who is at risk for getting the infection, such as children, elderly, immunocompromised, or malnourished people.

A. Apply topical antibiotics to the lesions twice a day. B. Cover the lesions with sterile gauze dressings. C. Wash the lesions with warm water and soap daily. D. Trim the child's fingernails and discourage scratching.

Correct Answer is A

Explanation

Choice A reason: This is a correct action. The nurse should apply topical antibiotics to the lesions twice a day to treat the infection and prevent its spread.

Choice B reason: This is an incorrect action. The nurse should not cover the lesions with sterile gauze dressings, because this can create a moist environment that promotes bacterial growth and delays healing.

Choice C reason: This is not a priority action. The nurse should wash the lesions with warm water and soap daily to remove crusts and debris, but this is not as important as applying topical antibiotics.

Choice D reason: This is not a priority action. The nurse should trim the child's fingernails and discourage scratching to prevent skin damage and secondary infection, but this is not as important as applying topical antibiotics.
