A   20-year-old primigravida    at  39  weeks’  gestation   was pushing in  the
second stage of labor for 90 min and has just delivered the fetal head.
However, in spite of vigorous pushing efforts by the mother and moderate
traction on the fetal head, you are unable to deliver the anterior shoulder.
Since delivery of the fetal head, 30 s has passed. The fetal heart rate is now
70 beats/min.
