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
The correct answer is **d. The newborn is beginning to cough**.
Choice A rationale:
An irregular respiratory rate in a newborn is not necessarily an indication for nasopharyngeal suctioning. Irregular respirations can have various causes, and suctioning may not be the appropriate intervention.
Choice B rationale:
A respiratory rate of 32 breaths per minute is within the normal range for a newborn and does not indicate the need for nasopharyngeal suctioning.
Choice C rationale:
A pulse oximetry reading of 91% is low and may indicate the need for intervention, but it does not specifically indicate the need for nasopharyngeal suctioning. Other interventions, such as supplemental oxygen, may be more appropriate.
Choice D rationale:
The newborn beginning to cough is a clear indication that there may be secretions or obstruction in the nasopharynx, and suctioning may be necessary to clear the airway and improve respiratory function.
Correct Answer is D
Explanation
Choice A rationale:
Fresh citrus fruits are not a good source of vitamin B12. They are rich in vitamin C but do not contain vitamin B12.
Choice B rationale:
Brown rice is not a good source of vitamin B12. While it is a nutritious grain, it does not contain vitamin B12.
Choice C rationale:
Raw carrots are not a good source of vitamin B12. Carrots provide essential nutrients but do not contain vitamin B12.
Choice D rationale:
Fortified soy milk is the correct choice as it is a suitable option for someone on a vegan diet looking to increase their vitamin B12 intake. Many brands of soy milk are fortified with vitamin B12, making it a reliable source for vegans. Vitamin B12 is essential for nerve function and red blood cell production, making it especially important during pregnancy.
