Problem: Ms. Brown delivered 30 minutes ago. Initially, the fundus was firm with only some "trickling" from the vagina. During the second 15-minute fundal check, the nurse notes the bleeding is filling a pad quickly. The fundus remains firm, but the bleeding remains bright red at a steady trickle. What is the probable etiology of the bleeding? Looking for Assignment Help? Select an answer. Retained placenta Placenta previa Laceration Hematoma
