Chapter 18: Problem 18

Describe the stages of labor.

Short Answer

Expert verified
Labor occurs in three primary stages: the dilation stage, where the cervix dilates to 10 centimeters, the expulsion stage, where the mother pushes the baby through the birth canal, and the placental stage, where the placenta is expelled from the mother's body.

Step by step solution

01

Describing the Dilation Stage

This is the first stage of labor, which begins with the onset of contractions. During this stage, the cervix dilates, or widens, to about 10 centimeters. This stage has three phases: early labor, active labor, and transition. Early labor is when the cervix dilates from 0 to 3 cm. Active labor is when the cervix dilates from 3 to 7 cm. The transition is when the cervix dilates from 7 to 10 cm.
02

Describing the Expulsion Stage

Also known as the second stage of labor, this begins when the cervix is fully dilated, and ends with the birth of the baby. This stage can last from a few minutes to several hours. During this stage, with each contraction, the mother pushes to help the baby move through the birth canal.
03

Describing the Placental Stage

This is the third and final stage of labor, occurring after the baby is born. During this stage, contractions continue until the placenta (also known as the 'afterbirth') is expelled. This may take between 5 to 30 minutes. This stage ends when the placenta has completely left the mother's body.
