What action should be taken if a patient shows signs of uterine hyperstimulation?

In the context of uterine hyperstimulation, which is characterized by excessive uterine contractions that may lead to fetal distress, the appropriate action is to administer tocolytics or decrease the oxytocin infusion while closely monitoring the fetal heart rate.

Tocolytics are medications that help relax the uterus and reduce the frequency of contractions. This is critical in preventing further complications for both the mother and fetus. Decreasing the oxytocin infusion is also vital, as oxytocin is often administered to induce or augment labor, and in cases of hyperstimulation, it can further exacerbate the situation.

Frequent assessment of the fetal heart rate is essential to monitor for any signs of distress due to hyperstimulation. By taking these actions, healthcare professionals can help ensure both maternal and fetal safety, allowing for the management of uterine activity in a careful and controlled manner.

The other options do not adequately address the critical need to mitigate hyperstimulation through medical intervention and careful monitoring, which is essential in this scenario.
