A) Increase the client's fluid intake: While maintaining adequate hydration is essential for postpartum recovery, it is not the priority intervention in this situation. The client's increased blood loss requires immediate attention to prevent complications such as hemorrhage. B) Prepare to administer oxytocic medication: Oxytocic medication may be indicated to stimulate uterine contractions and control bleeding in postpartum clients experiencing excessive bleeding. However, before administering medication, assessing the client's condition and determining the cause of bleeding is necessary to ensure appropriate intervention. C) Palpate the client's uterine fundus: This is the priority nursing intervention. Saturating two perineal pads with blood in a 30-minute period suggests excessive bleeding, which could be due to uterine atony or other postpartum complications. Palpating the uterine fundus helps assess for uterine tone, position, and any signs of uterine atony. If the fundus is boggy or deviated from the midline, it indicates uterine atony and requires immediate intervention. D) Assist the client on a bedpan to urinate: While assisting the client with urination is important for comfort and prevention of urinary retention, it is not the priority intervention in this situation. Assessing and managing the cause of excessive bleeding take precedence to prevent further complications.
