A nurse is assisting in the care of a client who gave birth 1 hour ago and is experiencing excessive vaginal bleeding.
Which of the following medications should the nurse anticipate the provider will prescribe?
Magnesium sulfate.
Tranexamic acid.
Betamethasone.
Terbutaline.
The Correct Answer is B
Choice A rationale
Magnesium sulfate is used to manage preeclampsia and prevent seizures, not for treating postpartum hemorrhage. It does not address the causes of excessive vaginal bleeding post-birth.
Choice B rationale
Tranexamic acid is an antifibrinolytic agent that helps reduce bleeding by preventing the breakdown of blood clots, making it suitable for managing postpartum hemorrhage.
Choice C rationale
Betamethasone is a corticosteroid used to mature fetal lungs in preterm labor, not for treating postpartum hemorrhage. It has no role in managing excessive bleeding after birth.
Choice D rationale
Terbutaline is a tocolytic used to delay preterm labor by relaxing uterine muscles. It is not used to manage postpartum hemorrhage and excessive vaginal bleeding.

Correct Answer is D
Explanation
Choice A rationale
A longitudinal fetal lie, where the baby is aligned vertically with the mother’s spine, is the normal and optimal position for labor. It typically does not cause prolonged or difficult labor.
Choice B rationale
A gynecoid pelvis is considered the most favorable pelvic shape for vaginal delivery. It is roomy and allows for the easiest passage of the baby through the birth canal, reducing the likelihood of prolonged labor.
Choice C rationale
General flexion, where the baby’s chin is tucked to its chest and the limbs are flexed, is the optimal fetal attitude for birth. This position facilitates a smoother and shorter labor process.
Choice D rationale
Persistent occiput posterior (OP) position, where the baby’s head is down but facing the mother’s front, can result in a difficult and prolonged labor. This position often leads to severe back pain for the mother and may complicate the labor process.
Correct Answer is D
Explanation
Choice A rationale
The amnion is a membrane that encloses the amniotic fluid but does not provide nutrients to the embryo.
Choice B rationale
The chorion forms part of the placenta and contributes to nutrient and gas exchange once the placenta develops, but it does not provide nutrients before the placenta forms.
Choice C rationale
The allantois is involved in early fluid exchange and waste management but does not provide nutrients before the placenta forms.
Choice D rationale
The yolk sac provides nutrients to the developing embryo before the placenta is fully functional, supporting early embryonic development.
