The three phases of labor are correctly identified as latent, active, and transition. This categorization helps healthcare professionals to understand the progression of labor as it unfolds.

In the latent phase, contractions begin to occur, and the cervix starts to dilate and efface. Women may experience mild contractions that become progressively stronger but generally are not yet frequent or intense enough to establish active labor status.

The active phase marks a change when contractions become more frequent, longer, and stronger, resulting in rapid dilation of the cervix, typically from about 6 centimeters to about 10 centimeters. This is when many women may seek hospitalization if they are at home.

Transition, as the final stage of labor, involves the most intense contractions, which can be both physically and mentally challenging. During this phase, the cervix completes its dilation to 10 centimeters, preparing for the descent and eventual birth of the baby.

The terminology used in this phase-based model is critical for assessing and managing labor progress, helping nurses and other healthcare professionals provide appropriate support and interventions.
