A nurse is caring for a preterm newborn who has hypoglycemia due to inadequate gluconeogenesis.

The nurse should understand that this condition occurs because preterm newborns have limited stores of which of the following substances?

Glycogen

Glucose

Insulin

Glucagon

Answer and Explanation

The Correct Answer is A

The correct answer is choice A. Glycogen. Preterm newborns have limited stores of glycogen, which is a substance made from glucose that is stored in the liver and muscle cells to be used later for energy. When blood glucose levels are low, the hormone glucagon signals the cells to convert glycogen back into glucose and release it into the bloodstream. However, preterm newborns have a reduced ability to produce glucagon and to use gluconeogenesis, which is the process of making new glucose from other sources. Therefore, they are at risk of hypoglycemia, which is a condition where blood glucose levels are too low to support normal brain function.

Choice B is wrong because glucose is the sugar that travels through the blood to fuel the cells, not a substance that is stored for later use.

Choice C is wrong because insulin is a hormone that helps cells absorb glucose from the blood, not a substance that is stored for later use.

Choice D is wrong because glucagon is a hormone that triggers the release of glucose from the liver and muscle cells, not a substance that is stored for later use.

Correct Answer is A

Explanation

The correct answer is choice A. Hypersensitivity.Erythromycin eye ointment is an antibiotic that can cause allergic reactions in some newborns, such as irritation, redness, swelling, or cloudy eyes.

This is a potential adverse reaction to this medication that the nurse should monitor for.

Choice B. Glaucoma is wrong because glaucoma is a condition that causes increased pressure in the eye and can damage the optic nerve.

It is not caused by erythromycin eye ointment.

Choice C. Cataracts is wrong because cataracts are a condition that causes clouding of the lens of the eye and can impair vision.

It is not caused by erythromycin eye ointment.

Choice D. Strabismus is wrong because strabismus is a condition that causes misalignment of the eyes and can affect depth perception.

It is not caused by erythromycin eye ointment.

Erythromycin eye ointment is used to prevent ophthalmia neonatorum, which is an infection of the eye surface that affects newborns within the first month of life.It can be caused by bacteria such as chlamydia or gonorrhea that can enter the baby’s eyes during childbirth and cause permanent damage to the corneas.Erythromycin eye ointment can help prevent vision loss caused by these bacteria.

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
