How is the transition phase of labor described in terms of cervical dilation?

The transition phase of labor is characterized by cervical dilation from 8 to 10 centimeters. This phase is crucial as it represents the final stage of the first labor stage, where the cervix must fully dilate to allow the fetus to descend into the birth canal. During this phase, women may experience intense contractions that can last for longer periods, typically occurring every 2 to 3 minutes and lasting for about 60 to 90 seconds. This stage can be intense and often marks a significant shift in a woman's labor experience, with many experiencing heightened emotions and physical sensations.

The other options represent different stages of cervical dilation during labor. The range of 0-3 centimeters corresponds to the latent phase, where early labor begins, and the cervix begins to soften and open. The dilation of 4-7 centimeters signifies the active phase, where labor becomes more active, and the contractions become stronger and more regular. The option referring to being fully effaced but not dilated would typically describe a situation where the cervix is primed and ready for labor, but the actual dilation for the transition phase has not yet occurred. Therefore, the correct description of the transition phase aligns with the range of 8 to 10 centimeters.
