The nurse had just given an intramuscular dose of methylergonovine (Methergine) to a client following delivery of an infant. The nurse determines that this medication had the intended effect after evaluating for which of the following findings?
1. Decreased pulse rate
2. Increased urine output
3. Improved uterine tone
4. Increased blood pressure
3
Rationale: Methylergonovine is an ergot alkaloid that is given following delivery to treat postpartum hemorrhage. It acts by vasoconstricting arterioles and directly stimulating uterine muscle contractions. Blood pressure may increase, but this is not the intended therapeutic effect. "Decreased pulse rate" and "increased urine output" are unrelated to the effects of this medication.
