A nurse recognizes that uterine hyperstimulation with oxytocin requires emergency interventions. What clinical cues would alert the nurse that the patient is experiencing uterine hyperstimulation? (Choose all that apply.)

Question

1. Uterine contractions lasting <90 seconds and occurring >2 minutes in frequency
2. Uterine contractions lasting >90 seconds and occurring <2 minutes in frequency
3. Uterine tone <20 mm Hg
4. Uterine tone >20 mm Hg
5. Increased uterine activity accompanied by a nonreassuring FHR and pattern.

Answer 1

2, 4, 5.
1. Incorrect. Uterine contractions that occur over 2 minutes apart and last less than 90 seconds are the expected goal of oxytocin induction.
2, 4, 5. Correct. Uterine contractions that are occurring less than 2 minutes apart and are lasting more than 90 seconds, a uterine tone of over 20 mm Hg, and a nonreassuring FHR and pattern are all indications of uterine hyperstimulation with oxytocin administration.
