The nurse caring for the pregnant patient must understand that the hormone essential for maintaining pregnancy is:
- A. estrogen.
- B. human chorionic gonadotropin (hCG).
- C. oxytocin.
- D. progesteron
Correct Answer: D
Rationale: The correct answer is D: progesterone. Progesterone is essential for maintaining pregnancy as it helps in thickening the uterine lining to support implantation and fetal development. Estrogen (choice A) plays a role in preparing the uterus for implantation but is not the primary hormone for maintaining pregnancy. Human chorionic gonadotropin (hCG) (choice B) is produced by the placenta and helps in detecting pregnancy but does not maintain it. Oxytocin (choice C) is involved in labor and breastfeeding, not in maintaining pregnancy.
