The nurse is caring for a multiparous client who is in labor and observes a fetal heart rate (FHR) that decreases with the peak of a contraction and returns to baseline in 30 seconds. Which action should the nurse implement?

Rationale: A. Turn the client to her side: Turning a client to her side is effective for relieving variable decelerations caused by cord compression, but the FHR is characteristic of early decelerations, which are usually benign and associated with fetal head compression. B. Perform a sterile vaginal exam: Early decelerations often occur when the fetal head is descending into the birth canal, indicating progress in labor. Performing a sterile vaginal exam helps assess cervical dilation and fetal station to determine labor progression, which is the most appropriate next action. C. Administer oxygen via facemask: Oxygen is indicated for late or variable decelerations associated with fetal hypoxia, but early decelerations are typically benign and do not require oxygen administration. D. Call the healthcare provider (HCP): Early decelerations are a normal physiologic response during labor. Immediate notification of the HCP is not required unless the pattern changes or other concerning signs develop.
