++
++
B. A patient at 35w3d with contractions every 7-20 minutes with cervical dilation of 1 cm 2 hours ago and cervical dilation of 1 cm now.
++
++
C. A patient at 33w3d with contractions every 3-5 minutes with cervical dilation of 1 cm 2 hours ago and cervical dilation of 3 cm now.
++
++
D. A patient at 31w3d with contractions every 7-20 minutes with cervical dilation of 1 cm 2 hours ago and cervical dilation of 1 cm now.

Abnormal labor may lead to cesarean delivery in some cases. When would a cesarean delivery be indicated based on abnormal labor?
++
++

A. A patient who is 4 cm dilated for 2 hours without cervical change without oxytocin augmentation.
++
++
B. A patient who is 4 cm dilated for 6 hours without cervical change with oxytocin augmentation.
++
++
C. A patient who is 6 cm dilated for 2 hours without cervical change without oxytocin augmentation
++
++
D. A patient who is 6 cm dilated for 6 hours without cervical change with oxytocin augmentation
+
++
D. The definition of active labor is 6 cm with rapid acceleration after this dilation is reached. Dysfunctional labor occurs when continued cervical change does not occur and labor progress is arrested. A cesarean section would be indicated in this patient.
++
A. is not correct since she only meets the older criteria for active labor.
++
B. is not correct since more recent studies have indicated a slower dilation process between 4 and 6 cm.
++
C. is in active labor and should begin oxytocin therapy as treatment for a slow second stage of labor.
