Final answer:
The woman most at risk for a uterine rupture is a gravida 2 who had a low-segment vertical incision for delivery of a 10-pound infant. This type of incision is known to have a higher risk for uterine rupture compared to transverse incisions. Multiple cesarean births and labor contractions could also contribute to increased risks.
Step-by-step explanation:
The nurse practicing in a labor setting knows that the woman most at risk for a uterine rupture is a gravida 2 who had a low-segment vertical incision for delivery of a 10-pound infant. A low-segment vertical incision is associated with a higher risk of uterine rupture compared to a low-segment transverse incision. Although multiple cesarean births increase the risk of uterine rupture, the type of incision plays a more crucial role in the risk assessment.
A Caesarean section is an alternative to labor and delivery that involves major abdominal surgery. It can lead to post-surgical complications, such as uterine rupture, which is a serious concern for women with previous cesarean deliveries, especially if the incision was vertical on the uterus.
Labor is divided into three stages, and during the second stage, the baby is expelled from the uterus. This stage involves contractions and the mother's efforts to push, which could be compromised if there is a previous scar from a cesarean delivery, hence increasing the risk of uterine rupture.
