A nurse is caring for a client who is experiencing a postpartum hemorrhage. Which of the following actions should the nurse take?

Choice A rationale Methylergonovine is an uterotonic agent that acts on the smooth muscle of the uterus to stimulate strong, sustained contractions, which are essential for compressing the intramyometrial blood vessels and achieving hemostasis to stop postpartum hemorrhage, especially from uterine atony. Choice B rationale While oxygen is important for hypoxia secondary to blood loss, administering it at 2 L/min via nasal cannula is typically insufficient for a client experiencing significant hemorrhage. High-flow oxygen, such as 10 to 15 L/min via nonrebreather mask, is usually required to maximize oxygen saturation. Choice C rationale Starting an IV bolus of Dextrose 5. Choice D rationale The knee-chest position is generally used to relieve cord compression or help with the manual rotation of the fetus, but it is not an established intervention for managing postpartum hemorrhage. The client should be positioned flat with legs elevated to promote venous return and manage shock.
