What are the three phases of the first stage of labor?

The three phases of the first stage of labor are correctly identified as Latent, Active, and Transition. During the latent phase, contractions begin and are generally mild, with dilation proceeding slowly from 0 to about 3-4 centimeters. This phase can last for several hours and is often characterized by feelings of excitement or anxiety as labor begins.

In the active phase, cervical dilation progresses more rapidly—typically from around 4 centimeters to about 7 centimeters. Contractions become stronger, more frequent, and more regular as the body prepares for the delivery process. This phase tends to indicate a transition into the more intense aspects of labor.

Finally, the transition phase, which is the last part of the first stage of labor, occurs when the cervix dilates from 7 to 10 centimeters. Contractions during this phase are typically very strong, close together, and may last longer. This phase can be particularly intense both physically and emotionally for the laboring person, as they are nearing the delivery of the baby.

Understanding these phases is crucial for monitoring the progress of labor and providing appropriate care and support. The other phrases do not accurately describe the recognized progression in the first stage of labor, which typically uses the terminology of latent, active, and
