Final answer:
Variable decelerations are caused by cord compression. Changing the mother's position and stopping the infusion of Pitocin can help alleviate these decelerations.
Step-by-step explanation:
The decelerations caused by cord compression, noted as V-shaped on the monitoring strip, are known as variable decelerations. These decelerations occur when there is pressure on the umbilical cord, restricting blood flow to the fetus. To address this issue, the mother's position should be changed to relieve the compression. If Pitocin is infusing, it should be stopped and the physician should be alerted.
