What are the three stages of labor?
Answer: First stage (dilation), second stage (birth), third stage (placenta)
Labor is divided into the first stage (cervical dilation), second stage (pushing and birth), and third stage (placental delivery).
What measurement indicates the cervix is fully dilated?
Answer: 10 centimeters
Full cervical dilation is 10 centimeters, which allows the baby's head to pass through the cervical opening into the vaginal canal.
What hormone is primarily responsible for triggering uterine contractions during labor?
Answer: Oxytocin
Oxytocin, released by the posterior pituitary gland, stimulates uterine contractions and plays a key role in labor progression.
What is effacement of the cervix?
Answer: Thinning and shortening of the cervix
Effacement is the process by which the cervix thins, shortens, and softens in preparation for and during labor.
What is the amniotic sac?
Answer: The fluid-filled membrane surrounding and protecting the fetus
The amniotic sac is a fluid-filled membrane that surrounds and cushions the fetus throughout pregnancy.
