The nurse caring for the pregnant patient understands that which hormone is essential for maintaining pregnancy?

Estrogen

Oxytocin

Human chorionic gonadotropin (hCG)

Progesterone

Answer and Explanation

The Correct Answer is D

Choice A rationale
Estrogen is a hormone that plays a crucial role in pregnancy. It helps develop the placenta and triggers increased blood volume and flow throughout pregnancy. However, it is not the primary hormone responsible for maintaining pregnancy.
Choice B rationale
Oxytocin is a hormone that plays a key role in labor and breastfeeding. It causes contractions during labor and helps eject milk during breastfeeding. However, it is not the primary hormone responsible for maintaining pregnancy.
Choice C rationale
Human chorionic gonadotropin (hCG) is a hormone produced during pregnancy. It is made almost exclusively in the placenta and its main function is to maintain the corpus luteum in the ovary and stimulate it to produce progesterone. However, hCG itself is not the primary hormone responsible for maintaining pregnancy.
Choice D rationale
Progesterone is the primary hormone responsible for maintaining pregnancy. It prevents the uterine muscles from contracting prematurely, which could lead to a miscarriage or preterm birth.

Correct Answer is D

Explanation

D. In a frank breech position (buttocks presenting first), fetal heart tones are usually heard above the umbilicus, as the fetal head is positioned in the upper uterus.

Correct Answer is ["-"]

Explanation

The nurse is observing a potential case of shoulder dystocia, a condition where the baby’s head has been delivered but one of the shoulders becomes stuck behind the mother’s pelvic bone. The nurse should monitor the mother’s vital signs and the baby’s heart rate. The nurse should call for immediate assistance, perform maneuvers to help deliver the baby, and prepare for a potential emergency cesarean section if necessary.
