A nurse is providing discharge instructions to a client who is breastfeeding her newborn. Which of the following instructions should the nurse include?

The correct answer is choice **b. Hearing loss**.

Choice A rationale:

Cataracts are not a common finding in newborns with congenital CMV infection. Cataracts are more commonly associated with other congenital infections like rubella, toxoplasmosis, and herpes simplex virus (HSV).

Choice B rationale:

Hearing loss is one of the most common manifestations of congenital CMV infection. Up to 40-58% of infants with symptomatic congenital CMV infection develop sensorineural hearing loss, which can be unilateral or bilateral, and progressive over time.

Choice C rationale:

Macrosomia, or large birth size, is not a typical finding in congenital CMV infection. In fact, infants with symptomatic congenital CMV infection are more likely to be small for gestational age or have intrauterine growth restriction.

Choice D rationale:

Urinary tract infection (UTI) is not a common presentation of congenital CMV infection. CMV can cause inclusion bodies in the urine, but overt UTI is not a typical finding. More common manifestations include petechiae, hepatosplenomegaly, jaundice, and central nervous system involvement.

Choice A rationale:

Hct (hematocrit) of 34% is a normal finding during pregnancy. Normal ranges vary during pregnancy, but generally, a hematocrit between 33% to 45% is considered normal during the second trimester.

Choice B rationale:

BUN (blood urea nitrogen) of 25 mg/dL should be reported to the provider. BUN measures kidney function, and during pregnancy, values above 20 mg/dL may indicate possible impaired kidney function, which requires further evaluation.

Choice C rationale:

Platelets of 170,000/mm³ are within the normal range during pregnancy. The normal platelet count during pregnancy is typically between 150,000 to 400,000/mm³.

Choice D rationale:

HbA1c (glycated hemoglobin) of 6% is a good indicator of blood sugar control and is within the target range for a pregnant woman with diabetes. The target HbA1c level for pregnant women with diabetes is usually around 6% or lower.
