After ambulating in the hall and returning to bed, the client states that her water broke.The fetal heart rate is 85 beats per minute, and the vaginal exam reveals the cervix is 90% effaced, 2 cm dilated, vertex presentation, and fetal station -2. There is a pulsating cord felt in the anterior portion of the vagina.Which intervention would the nurse perform immediately?

Choice A rationaleThe pulsating cord felt in the vagina indicates umbilical cord prolapse, a critical obstetric emergency. Immediately applying upward pressure to the presenting fetal part (vertex) manually elevates the fetus off the prolapsed cord. This action aims to relieve pressure on the umbilical vessels, thereby preventing fetal hypoxia and maintaining oxygen supply to the fetus until delivery can be expedited.Choice B rationaleWhile continuous fetal monitoring is essential, adjusting the monitor is not the immediate priority in the presence of a prolapsed umbilical cord and a significantly decreased fetal heart rate. The immediate intervention is to relieve pressure on the cord to improve fetal oxygenation.Choice C rationaleCalling the provider and preparing for an emergency cesarean section are necessary steps that should follow the immediate intervention. However, the very first action must be to relieve pressure on the prolapsed cord to prevent fetal compromise.Choice D rationalePositioning the client on her left side is a standard intervention for fetal distress or suspected vena cava syndrome, but in the case of a prolapsed umbilical cord, it is not the most immediate and effective action. Direct pressure on the presenting part is required to alleviate cord compression. .
