What is the typical duration of the second stage of labor?

The second stage of labor is defined as the period from full cervical dilation, which is 10 centimeters, to the delivery of the baby. This stage typically lasts from a few minutes to a couple of hours, depending on various factors such as the mother's previous birth experiences, the baby's position, and the strength of the contractions. During this phase, the mother will actively push to help guide the baby through the birth canal, and the duration can vary widely among different individuals and circumstances.

In contrast, the first stage of labor encompasses the time from the onset of contractions until full dilation occurs, which is why that option is not suitable. The third stage of labor begins after the baby is delivered and lasts until the placenta is expelled, making that option incorrect as well. The fourth option describes the timing of contractions rather than the duration of the stage itself, which does not accurately reflect the question being asked.
