Which phase of stage one labor is associated with cervix dilation of 8 to 10 cm?

• A. Latent phase
• B. Active phase
• C. Transition phase
• D. Expulsive phase

Answer: (C)

Dilation from about 8 to 10 cm occurs during the transition phase, the final part of stage one of labor. This phase comes after the latent phase (0–3 cm) and the active phase (roughly 4–7 cm), and it is when the cervix completes dilation to full 10 cm. Contractions during transition are typically the strongest and most frequent, and many people experience intense pressure, shaking, or nausea as the baby moves further down the birth canal. Once full dilation is reached, pushing begins in the second stage of labor.
