Final answer:
Nurses use the cervix as a key landmark during labor to assess the progress of birth. There are three stages of labor: cervical dilation, expulsion of the newborn, and delivery of the placenta. Pitocin may be used if labor stalls before the second stage is reached.
Step-by-step explanation:
Stages of Childbirth and Landmarks in Labor
During the assessment of a woman in labor, nurses use certain landmarks to determine the progress of birth. One important area identified as a landmark is the cervix. The stages of labor include:
- Stage 1: Cervical Dilation - The cervix thins and dilates, eventually reaching 10 cm to allow for the baby and placenta to pass through during birth.
- Stage 2: Expulsion of the Newborn - The baby is expelled from the uterus as it contracts and the mother pushes, utilizing her abdominal muscles to aid in delivery.
- Stage 3: Delivery of the Placenta - The placenta and associated fetal membranes are delivered after the baby is born.
If labor stalls before reaching Stage 2, Pitocin, a synthetic form of oxytocin, can be administered to restart and maintain labor. Additionally, the position of the newborn's shoulders relative to the mother can be a guiding landmark during childbirth.
