The nurse completed the fundal massage and turned up the oxytocin rate to 125 mL/hour. The client voided 400 ml on the bedpan. Because there is little improvement in fundal tone, and because of the risk of the oxytocin receptors being full and unresponsive to the oxytocin, the nurse has administered the next medication on the order sheet, 0.2 mg methylergonovine IM. The nurse has paged the provider to call back stat and review the other uterotonic medication options on the provider's orders. Which medication is contraindicated for this client?
