In transitions, cervical dilation progresses to ___.

In transitions, cervical dilation progresses to ___.

• A. 9 cm
• B. 10 cm
• C. 8 cm
• D. 11 cm

Answer: (B)

During the transition phase of the first stage of labor, the cervix goes from about 8 cm to full dilation. Full dilation is 10 cm, so the progression ends at 10 cm. The other numbers don’t fit because 8 cm is the start of transition, 9 cm is not complete dilation, and 11 cm would exceed typical physiological limits in a normal labor. Reaching 10 cm means the cervix is fully dilated and the baby can begin to descend for birth.
