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

A. Administering methylergonovine (Methergine) intramuscularly is appropriate for treating postpartum hemorrhage, as it stimulates uterine contractions to help control bleeding. B. The knee-chest position is not indicated for postpartum hemorrhage and does not address the underlying cause. C. Oxygen may be necessary if the client is unstable, but 2 L/min via nasal cannula is not the primary intervention and may not be sufficient in a critical situation. D. Dextrose water is not appropriate for fluid resuscitation during hemorrhage; isotonic fluids like normal saline or lactated Ringer’s are preferred to restore volume.
