Second Stage of Labor is defined as which interval?

• A. Onset of contractions to full dilation
• B. Fetal head visible at vaginal opening
• C. Delivery of placenta
• D. Full dilation to birth

Answer: (D)

Second stage of labor is the period from when the cervix is fully dilated (10 cm) to the birth of the baby. This is the pushing phase, where contractions and the mother’s expulsive efforts move the baby down the birth canal. Crowning, or the head becoming visible at the vaginal opening, can occur during this stage, but the interval ends with the baby’s delivery. The other options describe different events: the first stage runs from the onset of contractions to full dilation, and the third stage is the delivery of the placenta.
