A full-term infant is admitted to the newborn nursery 2 hours after delivery.The delivery record indicates the mother is positive for human immunodeficiency virus (HIV) and received zidovudine intravenously during labor. Which action should the nurse implement?

Choice A rationale Obtaining consent for the Hepatitis B vaccine is a necessary step in the newborn's care, but it is not the immediate priority for a newborn exposed to HIV. The focus should be on preventing HIV transmission from mother to child. Choice B rationale Collecting a venous specimen for serum glucose level is important for assessing the newborn's metabolic status, but it does not directly address the immediate need to reduce the risk of HIV transmission. Choice C rationale Assessing for the presence of the Moro reflex is part of a routine newborn examination and is important for evaluating the neurological status of the newborn. However, it does not address the immediate priority of HIV prophylaxis. Choice D rationale Ensuring that zidovudine is given within 6 hours after birth is critical for reducing the risk of mother-to-child transmission of HIV. Early administration of antiretroviral medication is essential to prevent viral replication and transmission to the newborn.
