The nurse is discussing a patient’s vaccination history at her 32-week gestation appointment.
The nurse knows that her teaching has been effective when the patient states:
I will go to the clinic to get my rubella shot today.
I will wait until after I have my baby to get my rubella shot.
I had my Tdap shot with my last baby 2 years ago, I do not need another now.
I will hold off on my flu shot this year.
The Correct Answer is B
Choice A rationale
Rubella vaccination is contraindicated during pregnancy due to the live virus, which poses a risk to the fetus. Administration should occur postpartum to avoid congenital rubella syndrome in the infant.
Choice B rationale
This statement is correct as rubella vaccination should be deferred until after delivery. It avoids exposure to the live virus during pregnancy, protecting fetal health.
Choice C rationale
The Tdap vaccine is recommended during each pregnancy, typically between 27 and 36 weeks gestation, to boost maternal antibodies and provide passive immunity to the newborn.
Choice D rationale
The flu vaccine is recommended during pregnancy to protect both the mother and the baby from influenza. It reduces the risk of severe illness and complications from the flu.

Correct Answer is C
Explanation
Choice A rationale
Terbutaline is a beta-agonist used to relax uterine muscles and delay preterm labor, not to augment labor in term pregnancies. It is not indicated for labor augmentation.
Choice B rationale
Betamethasone is a corticosteroid given to enhance fetal lung maturity in preterm pregnancies. It is not used to augment labor in term pregnancies, as it does not stimulate uterine contractions.
Choice C rationale
Pitocin (oxytocin) is a synthetic form of the natural hormone oxytocin. It stimulates uterine contractions and is commonly used to induce or augment labor in term pregnancies.
Choice D rationale
Magnesium sulfate is used primarily to prevent seizures in women with preeclampsia and to provide neuroprotection to preterm infants. It does not help augment labor contractions.
Correct Answer is D
Explanation
Choice A rationale
The maternal-fetal exchange of oxygen and waste products is affected by uterine contractions, as these compress the placental blood vessels, temporarily reducing blood flow.
Choice B rationale
Blood pressure variations during labor can influence perfusion but do not increase maternal-fetal exchange as uterine contractions primarily cause transient vascular compression.
Choice C rationale
Maternal-fetal exchange continues during contractions except when the uterine pressure is high enough to occlude placental blood flow, temporarily halting the exchange.
Choice D rationale
Uterine contractions compress the spiral arteries, reducing blood flow through the placenta, thereby diminishing maternal-fetal exchange of oxygen and waste products during contractions.
