A nurse is caring for a client who is receiving oxytocin to augment labor.The nurse notes recurrent variable decelerations of the FHR.Which of the following actions should the nurse take first?

Choice A rationaleInitiating an amnioinfusion may address recurrent variable decelerations caused by cord compression. However, discontinuing oxytocin to reduce uterine contractions and relieve compression is prioritized to improve fetal oxygenation.Choice B rationaleA vaginal/speculum exam is indicated if a prolapsed umbilical cord is suspected. However, it is not the first action in this scenario, where oxytocin discontinuation would take precedence.Choice C rationaleDiscontinuing the infusion of oxytocin is the first action because it reduces uterine contractions, alleviating cord compression, which is causing the variable decelerations of the fetal heart rate.Choice D rationaleProviding instructions for potential birth preparation does not address the immediate problem of variable decelerations. Intervening to alleviate the cause of the decelerations is the first priority. .
