A nurse is teaching a newborn's parent to care for the umbilical cord stump.
Which of the following instructions should the nurse include?.

The correct answer is choice A.

Choice A rationale:

The glucose challenge test is used to check for gestational diabetes during pregnancy. People at average risk of gestational diabetes usually have this test done during the second trimester, generally between 24 and 28 weeks of pregnancy.

Choice B rationale:

This is too early in the pregnancy to screen for gestational diabetes. The body’s response to sugar changes as the pregnancy progresses, so testing is typically done later.

Choice C rationale:

This is still a bit early for the screening. The recommended time is between 24 and 28 weeks of gestation.

Choice D rationale:

This is too late in the pregnancy for the screening. The recommended time is between 24 and 28 weeks of gestation.

The correct answer is choice B.

Choice A rationale:

Vitamin K is given to newborns to prevent bleeding disorders, not eye conditions.

Choice B rationale:

Erythromycin ophthalmic ointment is commonly used for prophylaxis of neonatal conjunctivitis (pink eye) caused by Neisseria gonorrhoeae and Chlamydia trachomatis.

Choice C rationale:

Gentamicin ophthalmic ointment can be used to treat bacterial infections of the eye, but it is not typically used for prophylaxis of neonatal eye conditions.

Choice D rationale:

Silver nitrate solution was once used for prophylaxis of neonatal eye conditions, but it is no longer commonly used due to the risk of chemical conjunctivitis.
