In the active phase, what is the dilation rate for multiparas during the maximum slope phase?

1. 3 cm per hour

2. 5.7 cm per hour

3. 1.5 cm per hour

4. 7 cm per hour

The correct answer is: 5.7 cm per hour

During the active phase of labor, the dilation rate for multiparas, or women who have previously given birth, typically accelerates significantly. The maximum slope phase refers to the time when cervical dilation occurs most rapidly. For multiparas, the expected dilation rate can be approximately 5 to 7 cm per hour, with many sources referencing around 5.7 cm per hour as an ideal average. This rate is notably higher than that for nulliparas—women who are giving birth for the first time—who generally experience a slower dilation rate during labor. An understanding of these rates is crucial for midwives to effectively monitor progress and provide appropriate support and interventions as necessary throughout labor. Therefore, identifying 5.7 cm per hour as the correct dilation rate for multiparas in the maximum slope phase reflects an accurate understanding of labor progress parameters according to current obstetric practices.
