A nurse is caring for a client who is postpartum and received methylergonovine.Which of the following findings indicates that the medication was effective?

Choice A rationaleMethylergonovine is an oxytocic medication that stimulates smooth muscle contraction of the uterus. While it can cause vasoconstriction and potentially lead to an increase in blood pressure, this is a potential side effect, not the intended therapeutic effect indicating the medication's effectiveness in the postpartum period. The primary goal is uterine contraction to control postpartum bleeding.Choice B rationaleBreast pain is related to engorgement and milk production, not directly influenced by methylergonovine's action on the uterus. The medication's effectiveness is assessed by its impact on uterine tone and bleeding, not breast comfort. Therefore, the absence of breast pain does not indicate that the methylergonovine has been effective.Choice C rationaleMethylergonovine is given to decrease postpartum bleeding by promoting uterine contraction, which helps to compress the blood vessels at the placental site. An increase in lochia (postpartum vaginal discharge) would suggest that the medication is not effective in achieving its intended therapeutic outcome of reducing hemorrhage.Choice D rationaleMethylergonovine's primary therapeutic effect in the postpartum period is to stimulate uterine smooth muscle contraction, leading to a firm fundus. A firm fundus indicates that the uterus is contracting effectively, which helps to compress blood vessels at the placental site and control postpartum bleeding. This is the desired outcome of methylergonovine administration.
