Final answer:
Doctors inject Sarah with synthetic oxytocin, Pitocin, to induce labor since she is well past her due date. Pitocin is used to stimulate uterine contractions and help labor progress through its three stages.
Step-by-step explanation:
Induction of Labor in Overdue Pregnancy
Sarah, a pregnant woman who is well past her due date, is being induced by the doctors. The medication commonly used for this purpose is synthetic oxytocin, known as Pitocin. This hormone is administered to stimulate uterine contractions, allowing the labor process to progress. There are three stages to labor: the dilation of the cervix, the expulsion of the baby, and the passage of the placenta. If labor stalls before it progresses beyond the first stage, Pitocin helps restart and maintain labor to safely deliver the baby and placenta.
