Choice A rationale:

Providing prenatal screening and testing for Zika virus infection is important in identifying if the fetus is affected by the virus. Early detection can help monitor and manage the pregnancy accordingly.

Choice B rationale:

Offering postnatal care and follow-up for babies with microcephaly is crucial because Zika virus infection during pregnancy can lead to congenital Zika syndrome, which may include microcephaly in newborns.

Choice C rationale:

Advocating for the rights and needs of pregnant women is essential in ensuring they receive appropriate care, support, and information about Zika virus infection during pregnancy.

Choice D rationale:

Implementing vector control activities to reduce mosquito breeding is vital in preventing the spread of Zika virus to pregnant women and reducing the risk of infection during pregnancy.

Choice E rationale:

Encouraging early pregnancy without delay is not a nursing intervention to reduce the risk of congenital Zika syndrome. It is not a relevant response to the question and does not address the management of Zika virus infection in pregnancy.
