A woman in labor has just received an epidural block. What is the most appropriate initial nursing action?

• A. Monitor the maternal blood pressure for possible hypotension
• B. Administer additional analgesia
• C. Assist with positioning for fetal descent
• D. Check urinary output

Answer: (A)

Epidural anesthesia can cause sympathetic blockade that leads to vasodilation and a drop in maternal blood pressure. Monitoring blood pressure right after the block allows you to detect hypotension early, which is crucial because a sudden decrease in BP can reduce uteroplacental perfusion and endanger the fetus. By identifying hypotension promptly, you can implement the primary actions to stabilize both mother and baby—positioning the mother in the left lateral side to improve venous return and uteroplacental blood flow, ensuring adequate IV fluid intake, and administering any prescribed vasopressors if needed. Other steps, like providing more analgesia, assisting with positioning for labor progression, or checking urinary output, are important but not the immediate priority until maternal hemodynamic stability is established.
