Cervical Dilatation Rate in Active Labor
The active phase of labor is typically characterized by more rapid cervical dilatation.
Primigravida Labor Progression
For a primigravida (a woman experiencing her first pregnancy), the expected normal rate of cervical dilatation during the active phase of labor is generally considered to be around 1 cm per hour.
Understanding Dilatation Rates
- While variations exist, a rate significantly slower than this can indicate potential issues requiring monitoring.
- The provided options represent different potential rates, with 1 cm/hour being the established norm for a primigravida in this stage.
Therefore, the normal rate of dilatation of the cervix in a primigravida in the active phase of labor is 1 cm/hour.
