A nurse is assessing a newborn whose mother had a primary cytomegalovirus (CMV) infection during pregnancy. The newborn acquired CMV transplacentally. Which of the following findings should the nurse expect the newborn to exhibit?
Cataracts
Hearing loss.
Macrosomia
Urinary tract infection (UTI)
The Correct Answer is B
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.

Correct Answer is D
Explanation
Choice A rationale:
This statement is incorrect. An indirect Coombs' test is not used to determine the risk of hypoglycemia in a baby after birth. It is used to detect antibodies against red blood cells, particularly in the context of blood incompatibility between a pregnant woman and her fetus.
Choice B rationale:
This statement is incorrect. An indirect Coombs' test is not related to determining the amount of amniotic fluid around the fetus. It is used primarily to assess for Rh incompatibility between the mother and fetus.
Choice C rationale:
This statement is incorrect. The test described here is a Doppler ultrasound, not an indirect Coombs' test. Doppler ultrasound is used to study blood flow in the fetus and placenta using ultrasound waves.
Correct Answer is A
Explanation
Choice A rationale:
This manifestation, urine output of 20 mL/hr, is an adverse reaction to magnesium sulfate administration. Magnesium sulfate can lead to decreased urine output, and it is essential for the nurse to monitor the client's urinary output closely. Low urine output may indicate decreased kidney function, which can be a sign of magnesium toxicity.
Choice B rationale:
Hypertension is expected in a client with preeclampsia, and magnesium sulfate is used to help manage and prevent seizures in these cases. While it is essential to monitor and manage hypertension during pregnancy, it is not considered an adverse reaction to magnesium sulfate.
Choice C rationale:
Hyperglycemia is not a common adverse reaction to magnesium sulfate. Magnesium sulfate may cause central nervous system depression, muscle weakness, and respiratory depression, but it does not typically cause hyperglycemia.
Choice D rationale:
A respiratory rate of 16/min is within the normal range for an adult and is not indicative of an adverse reaction to magnesium sulfate. Magnesium sulfate can cause respiratory depression at higher doses, but a respiratory rate of 16/min does not raise immediate concerns.
