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.

Choice E rationale
Amniotic fluid volume is one of the aspects evaluated during a biophysical profile. It is assessed to determine the amount of amniotic fluid surrounding the fetus.
Correct Answer is A
Explanation
Step 1 is to calculate the volume of Toradol to be drawn up. Toradol is available in 60 mg/mL. Therefore, to administer a dose of 30 mg, the nurse would need to draw up 30 mg ÷ 60 mg/mL = 0.5 mL.
