A newborn is delivered by cesarean section to a mother who is HIV-positive. The mother received antiretroviral therapy during pregnancy. Which intervention should the nurse implement?

Choice A's reason: Breastfeeding risks HIV transmission via milk, contraindicated despite maternal therapy; formula feeding is recommended to prevent postnatal infection in this scenario. Choice B reason: Antibiotics treat bacterial infections, not HIV; they’re unnecessary here unless a separate infection exists, irrelevant to HIV prevention post-cesarean delivery. Choice C reason: Delaying the bath preserves temperature but doesn’t address HIV; standard care includes early bathing, and this isn’t a priority intervention for HIV management. Choice D reason: Zidovudine post-birth reduces perinatal HIV transmission risk, standard prophylaxis for newborns of HIV-positive mothers, especially with maternal antiretroviral therapy.
