A nurse is teaching a newly licensed nurse about the uses of ultrasonography in the first trimester of pregnancy. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?

Choice A rationale:

Decreasing the maintenance IV solution infusion rate is not the appropriate action for addressing late decelerations of the fetal heart rate. Late decelerations are a concerning sign during labor, indicating possible fetal distress. This can be caused by inadequate oxygenation of the fetus, and reducing IV fluids would not directly address this issue.

Choice B rationale:

Placing the client in a lateral (side-lying) position is the correct action when late decelerations are observed. This position helps to improve uteroplacental blood flow and can relieve pressure on the inferior vena cava, thus increasing oxygen supply to the fetus.

Choice C rationale:

Administering oxygen via face mask at 2 L/min is not the priority action in response to late decelerations. While oxygen may be beneficial in certain situations, it is not the initial intervention for addressing fetal heart rate decelerations.

Choice D rationale:

Administering misoprostol 25 mcg vaginally is not appropriate for addressing late decelerations. Misoprostol is a medication used for cervical ripening and induction of labor, but it does not directly address fetal heart rate changes.

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.
