A primigravida client who is 5 cm dilated, 90% effaced, and at 0 station requests an epidural for pain relief. What is the most critical assessment finding for the nurse to report?

The most critical assessment finding to report in this scenario is a platelet count of 67,000/mm³. This finding is significant because an epidural anesthesia procedure requires specific precautions regarding the patient's platelet levels. A low platelet count, particularly below 100,000/mm³, poses a risk for bleeding complications during and after the procedure. With a platelet count of 67,000/mm³, the client may be at an increased risk for hematoma formation, which can lead to serious complications such as neurological deficits.

In contrast, while cervical dilation of 5 cm with 90% effacement is essential for understanding the progress of labor, it does not pose an immediate risk related to the anesthesia. Similarly, a white blood cell count of 12,000/mm³, although indicating some stress or inflammation, is not directly linked to the safety of administering an epidural. Hemoglobin of 12 mg/dl and hematocrit of 38% indicate adequate blood volume and oxygen-carrying capacity, and are also not critical in the context of performing an epidural. Therefore, the platelet count's relevance to preventing potential complications during the anesthesia process makes it the most critical finding to report.
