A nurse is caring for a client who is in the second stage of labor. The nurse observes retraction of the fetal head against the maternal perineum as the head is birthed.
Which condition is the client most likely experiencing?

Choice A rationale
Vaginal discharge is common during pregnancy due to the increased production of estrogen and greater blood flow to the pelvic area. It is not typically a sign of preeclampsia.
Choice B rationale
Elevated blood pressure is a primary symptom of preeclampsia. If a pregnant client has high blood pressure, it should indicate to the nurse that the client requires further evaluation for this disorder.
Choice C rationale
Joint pain is not typically a symptom of preeclampsia. It could be related to other conditions or simply a result of the physical changes of pregnancy.
Choice D rationale
Increased urine output is not typically associated with preeclampsia. In fact, decreased urine output could potentially be a sign of kidney problems related to preeclampsia.

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.
