When a client is receiving oxytocin (Pitocin) to treat postpartum hemorrhage, the nurse should anticipate monitoring for uterine hyperstimulation as a common adverse reaction. Uterine hyperstimulation occurs when there are excessively frequent or prolonged contractions of the uterus. This can lead to decreased blood flow to the placenta, resulting in fetal distress.
