A nurse is administering erythromycin eye ointment to a newborn who has a history of allergic reaction to penicillin.

What should the nurse do before applying the ointment?

Ask the mother if she has any allergies to antibiotics

Check if there is any cross-sensitivity between erythromycin and penicillin

Apply a small amount of ointment on the skin to test for allergic reaction

Administer an antihistamine to prevent anaphylaxis

Answer and Explanation

The Correct Answer is B

The correct answer is choice B. Check if there is any cross-sensitivity between erythromycin and penicillin. Erythromycin is a macrolide antibiotic that can be used to treat bacterial eye infections in newborns and adults.

Penicillin is a beta-lactam antibiotic that can cause allergic reactions in some people.

Cross-sensitivity means that a person who is allergic to one type of antibiotic may also be allergic to another type of antibiotic that has a similar structure or mechanism of action. Erythromycin and penicillin have different structures and mechanisms of action, but there is still a small chance of cross-sensitivity between them.

Therefore, the nurse should check if the newborn has any history of allergic reaction to penicillin before applying the erythromycin eye ointment.

Choice A is wrong because asking the mother if she has any allergies to antibiotics is not enough to determine if the newborn is at risk of an allergic reaction to erythromycin.

The newborn may have inherited or developed an allergy to penicillin or erythromycin that the mother does not have.

Choice C is wrong because applying a small amount of ointment on the skin to test for allergic reaction is not a reliable method to diagnose an allergy. Skin testing can cause false positive or false negative results, and it may also trigger a severe allergic reaction in some cases.

Choice D is wrong because administering an antihistamine to prevent anaphylaxis is not appropriate for a newborn who has not been exposed to the allergen yet.

An antihistamine is a medication that blocks the effects of histamine, a chemical that causes allergic symptoms.

Anaphylaxis is a life-threatening allergic reaction that involves multiple organ systems and requires immediate medical attention. An antihistamine cannot prevent anaphylaxis, and it may also cause side effects such as drowsiness, dry mouth, or low blood pressure in a newborn.

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

Explanation

The correct answer is choice A, B, C, D and E.All of these are possible modes of transmission for hepatitis B virus (HBV), which is a viral infection that attacks the liver and can cause both acute and chronic disease.The virus is most commonly transmitted from mother to child during birth and delivery, as well as through contact with blood or other body fluids during sex with an infected partner, unsafe injections or exposures to sharp instruments.

Choice A is correct because unprotected sexual contact can expose a person to the blood, semen, or vaginal fluids of an infected partner.

Choice B is correct because sharing drugs, needles, or “works” when using drugs can expose a person to the blood of an infected person.

Choice C is correct because poor infection control practices in medical settings can expose a person to contaminated needles or syringes or sharp objects that have been used on an infected person.

Choice D is correct because sharing of blood sugar (diabetes) testing equipment can expose a person to the blood of an infected person.

Choice E is correct because needle sticks or sharps exposures on the job can expose a person to the blood of an infected

A. “I should use a clean cloth and warm water to wash around the umbilical cord.” B. “I should bathe him before a feeding so he won’t spit up.” C. “I should avoid getting water in his ears or eyes.” D. “I should avoid getting water in his ears or eyes.”

Correct Answer is B

Explanation

The correct answer is choice B.“I should bathe him before a feeding so he won’t spit up.” This statement indicates a need for further instruction because it is not advisable to bathe a newborn infant before a feeding, as this may cause hypoglycemia or cold stress.The mother should bathe the infant after a feeding or between feedings when the infant is alert and comfortable.

Choice A is wrong because it is correct to use a clean cloth and warm water to wash around the umbilical cord.This helps prevent infection and promotes drying of the cord stump.

Choice C is wrong because it is correct to avoid getting water in the infant’s ears or eyes.This helps prevent ear infections and eye irritation.

Choice D is wrong because it is correct to dry the infant thoroughly and dress him warmly after bathing.

This helps prevent heat loss
