Which of the following changes in the fetal heart rate (FHR) should a nurse report to the provider for a client who is in labor and receiving epidural analgesia?

Choice A reason: Early decelerations of the FHR result from head compression during contractions, a benign response reflecting vagal stimulation. They mirror contraction patterns and do not indicate fetal distress. Epidural analgesia may reduce maternal blood pressure, but early decelerations are unrelated to hypoxia, requiring no immediate reporting in this context. Choice B reason: FHR accelerations of 15 beats/min for 15 seconds indicate fetal well-being, reflecting a responsive autonomic nervous system. They occur with fetal movement or stimulation and are not concerning. Epidural analgesia does not typically cause accelerations, and these findings do not warrant reporting, as they signify normal fetal oxygenation and neurological function. Choice C reason: An FHR of 150/min is within the normal range (110-160/min) and does not indicate distress. Epidural analgesia may cause maternal hypotension, affecting placental perfusion, but a stable FHR within normal limits reflects adequate fetal oxygenation. This finding does not require immediate reporting, as it aligns with normal fetal physiology. Choice D reason: Prolonged absent FHR variability suggests fetal compromise, as variability reflects autonomic nervous system function and oxygenation. Epidural analgesia can cause maternal hypotension, reducing placental perfusion and leading to hypoxia, which diminishes variability. This critical finding requires immediate reporting to address potential fetal distress and prevent adverse outcomes like acidosis.
