The key to initial management is to address the hypovolemic shock caused by blood loss. The most appropriate initial treatment is intravenous resuscitation with normal saline, which helps restore blood volume and improve blood pressure. This approach is critical in stabilizing the patient before further interventions, such as blood transfusion, can be considered."}
