What is the priority nursing intervention for a patient experiencing umbilical cord prolapse during labor?

Choice A rationaleWhile assessing cervical dilation is important for understanding the progress of labor, it is not the priority intervention in the case of umbilical cord prolapse. The immediate danger is fetal oxygen deprivation due to compression of the prolapsed cord. Delaying intervention to perform a cervical exam could worsen fetal hypoxia.Choice B rationaleIncreasing the rate of intravenous fluids might be indicated to support maternal blood pressure and placental perfusion, but it does not directly address the immediate problem of cord compression. The priority is to relieve pressure on the umbilical cord to restore fetal oxygen supply.Choice C rationaleAdministering oxygen to the mother is a helpful supportive measure to increase the oxygen available to the fetus. However, it does not directly relieve the compression on the umbilical cord, which is the immediate life-threatening situation for the fetus.Choice D rationaleRepositioning the mother to a knee-chest position (or Trendelenburg) uses gravity to help relieve pressure on the prolapsed umbilical cord by moving the presenting part of the fetus away from the pelvis. This is the priority nursing intervention as it directly aims to improve fetal oxygenation by reducing cord compression until the fetus can be delivered. .
