A 25-year-old primigravida is in the active phase of the first stage of labor. According to Friedman's and modern labor curves, what is the minimum expected rate of cervical dilation in a nulliparous woman during the active phase?
- A.0.5 cm/hour
- B.1.2 cm/hourCorrect answer
- C.2.0 cm/hour
- D.2.5 cm/hour
Solution
According to classic Friedman's curves, the minimum rate of cervical dilation in nulliparous women during the active phase is 1.2 cm/hour (and 1.5 cm/hour for multiparous women). Modern WHO guidelines consider a slower rate than 1 cm/hour as abnormal, but standard textbook value for nullipara active phase dilation limit is 1.2 cm/hour.
