A nurse is caring for a client who is receiving oxytocin to augment labor.The client has an intrauterine pressure catheter and an internal fetal scalp electrode for monitoring.Which of the following is an indication that the nurse should discontinue the infusion?

Choice A rationaleContraction frequency every 3 minutes indicates an acceptable labor pattern. Adequate uterine contractions are essential for labor progression and are not a reason to discontinue oxytocin infusion.Choice B rationaleContraction duration of 100 seconds is excessive and poses risks of uterine hyperstimulation, which may lead to uterine rupture, fetal hypoxia, or distress, necessitating discontinuation of the oxytocin infusion.Choice C rationaleFetal heart rate with moderate variability indicates normal fetal well-being. Moderate variability reflects a healthy autonomic nervous system in the fetus and does not warrant stopping oxytocin infusion.Choice D rationaleFetal heart rate of 118/min is within the normal range of 110 to 160 beats per minute. This rate does not indicate fetal distress or hyperstimulation requiring intervention.
