A nurse is caring for a laboring person who is receiving oxytocin for labor induction. What is the priority intervention when uterine hyperstimulation occurs?
- A. stop the oxytocin infusion
- B. increase the oxytocin infusion
- C. administer IV fluids
- D. administer an epidural
Correct Answer: D
Rationale: The correct answer is D: administer an epidural. Uterine hyperstimulation during labor can lead to fetal distress and complications. Administering an epidural can help manage pain and relax the uterus, reducing the risk of hyperstimulation. Stopping the oxytocin infusion (choice A) is also important, but managing the uterine contractions with an epidural takes priority. Increasing the oxytocin infusion (choice B) would exacerbate the hyperstimulation. Administering IV fluids (choice C) may be helpful, but it does not directly address the uterine hyperstimulation.
