Correct Answer: C

Rationale: Recurrent variable decelerations during labor can indicate umbilical cord compression, which can result in fetal hypoxia and distress. Discontinuing the oxytocin infusion is the priority in this situation as oxytocin can cause or exacerbate uteroplacental insufficiency leading to fetal distress. By discontinuing the oxytocin, the nurse can help improve fetal oxygenation and alleviate the variable decelerations. After stopping the oxytocin infusion, the nurse should continue to monitor the fetal heart rate pattern and follow the healthcare provider's orders for further management if needed.
