Describe the three stages of labor and delivery
What will be an ideal response?
A good answer will be similar to the following:
+ Stage 1
- Begins when the muscles of the uterus start to contract.
- Contractions cause the cervix to enlarge — goes from 0 to 10 centimeters.
- Stage 1 lasts for 12 to 24 hours during the birth of a first child.
- Stage 1 is usually shorter for later-born children.
+ Stage 2
- Begins when the cervix is fully enlarged.
- Most women feel a strong urge to push the baby out, using their abdominal muscles.
- This pushing, along with uterine contractions, pushes the baby down the birth canal.
- The top of the baby's head soon appears (crowning).
- In about an hour or less, the baby passes through the birth canal and emerges from the
mother's body.
- The baby's birth marks the end of the second stage of labor.
+ Stage 3
- The placenta is expelled from the uterus.
- This stage is brief, usually lasting 10 to 15 minutes.
