The patient declines the use of oxytocin or any other further testing and decides to await a spontaneous delivery. Five weeks later, she comes to the emergency department complaining of vaginal bleeding for 1 hour. Her pulse is 110/min, respirations are 18/min, and blood pressure is 112/76 mm Hg. Pulse oximetry on room air shows an oxygen saturation of 97%. Pelvic examination shows active vaginal bleeding. Laboratory studies show: Hemoglobin 12.8 g/dL Leukocyte count 10,300/mm3 Platelet count 105,000/mm3 Prothrombin time 26 seconds (INR=1.8) Serum Na+ 139 mEq/L K+ 4.1 mEq/L Cl- 101 mEq/L Urea nitrogen 42 mg/dL Creatinine 2.8 mg/dL Which of the following is the most likely underlying mechanism of this patient's symptoms?

Forty-five minutes after the spontaneous delivery of a male newborn at 39 weeks' gestation, a 27-year-old primigravid woman complains of worsening abdominal pain and dizziness.
