Answer: Cesarean birth probably will be necessary.
Explanation: A cesarean birth may be performed when the fetus is in the breech presentation because the risk of morbidity and mortality is increased. A vertex presentation in the occiput posterior position usually causes back pain. Labor is usually longer with a fetus in the breech presentation because the buttocks are not as effective as the head as a dilating wedge. Meconium is a common finding in the amniotic fluid of a client whose fetus is in a breech presentation, because contractions compress the fetal intestinal tract, causing release of meconium.
