A nurse midwife is examining a patient who is at 42 weeks of gestation and believes she is in labor.
Which of the following findings would confirm to the nurse that the patient is in labor?
Amniotic fluid present in the vaginal vault.
Cervical dilation observed.
Brownish vaginal discharge noted.
Patient reports pain above the umbilicus.
The Correct Answer is B
Cervical dilation is a key sign that a patient is in labor. As labor progresses, the cervix dilates to allow the baby to pass through the birth canal. Other signs of labor can include regular contractions, rupture of membranes (amniotic fluid present in the vaginal vault), and changes in vaginal discharge.

Correct Answer is B
Explanation
The correct answer is Choice B.
Choice A rationale
Variable decelerations are not related to fetal head compression. Fetal head compression typically results in early decelerations, not variable ones.
Choice B rationale
Variable decelerations are indeed due to umbilical cord compression. They are quick decreases in fetal heart rate that vary with uterine contractions. This can be a sign that the baby’s blood flow is reduced if variable decelerations happen over and over.
Choice C rationale
Uteroplacental insufficiency typically results in late decelerations, not variable ones. Late decelerations are a sign of fetal hypoxia and are associated with uteroplacental insufficiency.
Choice D rationale
While certain medications can affect the fetal heart rate, variable decelerations are not typically a result of the administration of narcotic analgesics.
Correct Answer is D
Explanation
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.
