The nurse caring for the pregnant patient understands that which hormone is essential for maintaining pregnancy?
Estrogen
Oxytocin
Human chorionic gonadotropin (hCG)
Progesterone
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.

Explanation
Choice A rationale
Assessing deep tendon reflexes every hour is a common practice in managing severe preeclampsia. Hyperreflexia can be a sign of worsening pre-eclampsia.
Choice B rationale
Continuous fetal monitoring is typically recommended for patients with severe pre-eclampsia. This allows for early detection of fetal distress.
Choice C rationale
Ambulating twice daily may not be appropriate for a patient with severe pre-eclampsia at 35 weeks of gestation. Bed rest is often recommended to help lower blood pressure and reduce the risk of complications.
Choice D rationale
Obtaining a daily weight is a common practice in managing severe pre-eclampsia. Sudden weight gain can be a sign of worsening pre-eclampsia.
Correct Answer is C
Explanation
If a patient in labor at 40 weeks of gestation reports saturating two perineal pads in the past 30 minutes, and placenta previa is suspected, an appropriate nursing action would be to prepare for a cesarean birth. Placenta previa, where the placenta partially or completely covers the cervical opening, can cause significant bleeding and is typically managed with a cesarean delivery to prevent further bleeding and ensure the safety of the mother and baby.
