Methergine is prescribed for a woman to treat postpartum hemorrhage.Before administration of this medication, the priority nursing assessment is to check the:

Choice A rationaleMethergine (methylergonovine) is an oxytocic medication that causes vasoconstriction and increases blood pressure. It is contraindicated in clients with hypertension. Therefore, assessing the client's blood pressure before administration is crucial to ensure safety. Normal adult blood pressure is typically less than 120/80 mmHg.Choice B rationaleAssessing uterine tone is important in managing postpartum hemorrhage, as a boggy uterus contributes to bleeding. However, before administering a medication that affects blood pressure, the blood pressure itself is the priority assessment due to the contraindications of Methergine in hypertensive clients.Choice C rationaleDeep tendon reflexes are assessed in the postpartum period, particularly for clients with preeclampsia who are at risk for magnesium sulfate toxicity. While important, it is not the priority assessment before administering Methergine, which has a direct impact on blood pressure.Choice D rationaleAssessing the amount of lochia is essential for monitoring postpartum bleeding. However, before administering Methergine, which can significantly increase blood pressure, ensuring the client does not have a contraindication related to hypertension is the most critical immediate assessment. .
