A 34-year-old multiparous woman delivers a 4200-g (9 lb 4 oz) neonate vaginally following a prolonged second stage of labor. Routine prophylactic intravenous oxytocin is administered immediately after delivery. Ten minutes later, the placenta delivers spontaneously and intact. Shortly after, the patient develops profuse vaginal bleeding. Her blood pressure is 90/50 mm Hg, and her pulse is 118/min. On abdominal examination, the uterine fundus is soft, boggy, and palpable just above the umbilicus. Speculum examination reveals no vaginal or cervical lacerations. Arrange the following management steps for this patient's hemorrhage in the correct sequential order, from the initial immediate intervention to the most invasive definitive treatment.
- 1Perform bimanual uterine massage
- 2Administer a second-line uterotonic medication
- 3Insert an intrauterine balloon tamponade
- 4Proceed with exploratory laparotomy and placement of a uterine compression suture
