Final answer:
The condition described happens when labor is incomplete, with some POC expelled but the cervix still dilated. In usual labor, there are three stages culminating in the expulsion of the baby followed by the placenta. If labor stalls, Pitocin may be used to restart it.
Step-by-step explanation:
The condition in which some products of conception (POC) are expelled while the cervix remains dilated could describe a scenario in which the labor process is incomplete. There are three stages to labor: the first stage where the cervix thins and dilates, necessary for the baby and placenta to be expelled during birth, usually dilating to about 10 cm; the second stage where the baby is expelled from the uterus; and the last stage, which involves the passage of the placenta after the baby has been born and has completed disengagement from the uterine wall. If labor halts before the second stage is completed, interventions such as the administration of synthetic oxytocin, known as Pitocin, may be utilized to restart and maintain labor.
