Labor And Delivery Practice Test

A 29-year-old G3P2 woman is in the second stage of labor. Following delivery of the fetal head, it is noted to retract against the perineum. The infant's anterior shoulder cannot be delivered with gentle downward traction.

A 26-year-old primigravid woman at 40 weeks of gestation is being monitored for labor progression. She was admitted in the active phase of labor. Four hours ago, her cervical examination was 7 cm dilation, 100% effacement, and 0 station. An intrauterine pressure catheter is in place and shows contractions with an average of 220 Montevideo units (MVUs). A repeat examination now shows her cervix is unchanged at 7 cm. The fetal heart rate tracing is reassuring.
