During labor augmentation with oxytocin, which finding indicates the nurse should discontinue the infusion?

During labor augmentation with oxytocin, a contraction duration of 100 seconds is a critical finding that indicates the nurse should discontinue the infusion. In normal labor, uterine contractions should last between 45 to 90 seconds. When contractions last longer than this, such as in the case of a 100-second duration, there is an increased risk of uterine hyperstimulation.

Uterine hyperstimulation can lead to concerning maternal and fetal outcomes, such as impaired placental perfusion and fetal distress due to reduced oxygen supply. Thus, monitoring the duration of contractions is essential to ensure both maternal and fetal well-being. If the contractions are too prolonged, as in this scenario, immediate intervention is warranted to prevent potential complications.

While other options may suggest normal or acceptable labor patterns, they do not pose any immediate risks that would require the discontinuation of the oxytocin infusion. Therefore, recognizing the significance of a contraction duration that exceeds safe limits is vital in managing oxytocin infusion during labor.
