A nurse is caring for a 2-year-old child who has impetigo contagiosa on his face
and hands. Which of the following actions should
the nurse take?
Apply topical antibiotics to the lesions twice a day.
Cover the lesions with sterile gauze dressings.
Wash the lesions with warm water and soap daily.
Trim the child's fingernails and discourage scratching.
The Correct Answer is A
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.

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.
