Which option correctly lists the four components of cervical change?

• A. cervical ripening, position of the cervix, dilation, effacement
• B. dilation, descent, effacement, fetal heart rate
• C. cervical ripening, position of the cervix, dilation, effacement
• D. position of the cervix, dilation, effacement, cervical ripening

Answer: (C)

Cervical change during labor is described by four interrelated elements: cervical ripening, the position of the cervix, dilation, and effacement. Cervical ripening refers to the cervix softening and becoming more distensible so it can dilate. The position of the cervix describes where the cervix is located relative to the vaginal canal (often moving from posterior toward anterior as labor progresses). Dilation measures how open the cervix has become, from 0 to about 10 centimeters. Effacement describes thinning and shortening of the cervix, commonly expressed as a percentage. Together, these four components capture how the cervix changes to prepare for birth. The option listed includes cervical ripening, position of the cervix, dilation, and effacement, which matches this set.
