In which stage of labor does full dilation of the cervix occur?

The first stage of labor is characterized by the process of cervical dilation, which begins with the onset of labor contractions and continues until the cervix is fully dilated to 10 centimeters. This stage is further divided into the latent phase, where early contractions lead to gradual dilation, and the active phase, which involves more intense contractions and rapid cervical changes. Full dilation signifies that the cervix has opened wide enough to allow the fetus to move into the birth canal during the subsequent stage of labor.

The second stage of labor begins once the cervix is fully dilated, during which the mother will actively push to deliver the baby. The third stage involves the delivery of the placenta, and the fourth stage refers to the recovery period post-delivery. Understanding these stages is crucial for EMTs and other medical professionals as they provide care and support during childbirth.
