Which of the following is the most common cause of postpartum hemorrhage?
Uterine atony is the most common cause of postpartum hemorrhage, accounting for up to 80% of cases. It occurs when the uterus does not contract enough to stop the bleeding from the placental site. Uterine atony can be caused by factors such as prolonged labor, multiple pregnancy, large baby, infection or use of certain medications.
Retained placenta is the second most common cause of postpartum hemorrhage, but it only accounts for about 10% of cases. It occurs when part or all of the placenta remains attached to the uterine wall and prevents the uterus from contracting properly.
Lacerations are tears or cuts in the cervix, vagina or perineum that can cause bleeding after delivery. They are usually minor and can be repaired with stitches, but they can also be severe and require surgery. Lacerations are not very common causes of postpartum hemorrhage, and they usually occur along with other factors such as uterine atony or retained placenta.
Hematomas are collections of blood under the skin or in the tissues that can result from trauma during delivery. They can cause pain, swelling and pressure in the affected area, but they are usually small and resolve on their own.
Hematomas are rare causes of postpartum hemorrhage, and they usually occur along with other factors such as lacerations or coagulation disorders.

Normal ranges for blood loss after delivery are less than 500 mL for vaginal birth and less than 1000 mL for cesarean birth. Blood loss greater than these amounts can indicate postpartum hemorrhage and require immediate medical attention.
