A nurse is providing teaching to the parents of a newborn who has a prescription for a home phototherapy biliblanket.
Which of the following statements should the nurse include in the teaching?

Choice A rationale

Diphtheria-acellular pertussis (Tdap) vaccine is recommended for pregnant clients during the third trimester, specifically between 27 and 36 weeks of gestation. This timing optimizes the transfer of maternal antibodies to the fetus, providing passive immunity against pertussis (whooping cough) in the newborn during their vulnerable early months, before they are old enough to receive their own vaccinations.

Choice B rationale

Inactivated influenza vaccine is highly recommended for pregnant clients during any trimester of pregnancy. Pregnancy alters the immune system, making pregnant individuals more susceptible to severe complications from influenza. Vaccination protects both the mother and, through passive antibody transfer, the newborn from influenza infection.

Choice C rationale

Varicella vaccine is a live attenuated vaccine and is contraindicated during pregnancy due to the theoretical risk of fetal infection. While the actual risk is very low, it is generally deferred until the postpartum period. Women of childbearing age should be screened for immunity and vaccinated if non-immune prior to conception or postpartum.

Choice D rationale

Measles, mumps, and rubella (MMR) vaccine is a live attenuated vaccine and is contraindicated during pregnancy due to the theoretical risk of fetal infection, particularly with rubella. Rubella infection during pregnancy can lead to congenital rubella syndrome, causing severe birth defects. Vaccination should occur before conception or postpartum.

Choice E rationale

Human papillomavirus (HPV) vaccine is not routinely recommended during pregnancy. While current data do not suggest harm, the vaccine has not been extensively studied in pregnant individuals. Vaccination should be completed before pregnancy or deferred until the postpartum period.

1. Administer magnesium sulfate bolus: Anticipated. Magnesium sulfate is the drug of choice to prevent seizures in severe preeclampsia or eclampsia. The client shows signs of severe preeclampsia (hypertension, headache, visual disturbances, hyperreflexia, clonus, epigastric pain), so a magnesium sulfate bolus is appropriate to reduce CNS irritability and prevent eclamptic seizures.
2. Insert an indwelling urinary catheter: Anticipated. Monitoring urine output is essential in hypertensive disorders of pregnancy to assess kidney function and fluid balance. The client’s urine output (25–55 mL/hr) is borderline low (normal >30 mL/hr), so catheter insertion allows accurate measurement.
3. Initiate intravenous (IV) fluids: Contraindicated. In preeclampsia, patients often have intravascular volume depletion with risk of pulmonary edema due to increased capillary permeability. IV fluids should be carefully restricted to avoid fluid overload, so routine IV fluid initiation is contraindicated unless hypovolemia or dehydration is confirmed.
4. Administer nifedipine 30 mg intermittent IV bolus: Contraindicated. Nifedipine, a calcium channel blocker, is given orally for hypertension in pregnancy, but intermittent IV bolus administration is not recommended because it can cause abrupt hypotension and fetal distress.
5. Begin intermittent electronic fetal monitoring: Anticipated. Continuous or intermittent fetal monitoring is critical for detecting fetal distress, especially in high-risk pregnancies with maternal hypertension and irregular contractions, ensuring timely intervention if needed.
