### Patient: Doctor, I fell off my bike and hit my head pretty hard. I have an open wound on my head that won't stop bleeding. Can you help me?
### Doctor: Of course, we need to suture the wound immediately. But before that, we need to perform a radiographic imaging procedure to check for any internal bleeding or skull fracture. We may also need to perform a scan ct or head ct to get a better view of the injury. In addition, we need to manage the wound effectively to prevent any infection. As this is a head injury, we also need to check your blood alcohol level and prothrombin time through a blood test to make sure there is no internal bleeding or clotting problem.
