A newborn infant is prescribed an immunization prior to discharge. Which action should the practical nurse (PN) implement?

A. Ask the mother if she wants the infant immunized for Haemophilus influenzae: While parental involvement is important, the Hib vaccine is a standard immunization recommended for all infants. B. Prepare the first dose for Diphtheria, tetanus toxoid and acellular pertussis (DTaP): DTaP is typically given at 2 months of age, not immediately at birth. Administering vaccines not indicated at the newborn stage could lead to scheduling errors or adverse outcomes. C. Give the first dose of the Rotavirus vaccine if any sibling have diarrhea now: Rotavirus vaccination is contraindicated if there is active gastrointestinal illness. However, the immediate priority is obtaining consent for the vaccines appropriate for the newborn, rather than assessing sibling health. D. Obtain signed consent from the mother for administration of Hepatitis B vaccine: Legal and ethical standards require informed consent before administering vaccines to a newborn. The Hepatitis B vaccine is recommended at birth, and obtaining consent ensures the PN can safely and appropriately proceed with administration.
