### Patient: Doctor, I fell and got an open wound on my face. It's bleeding a lot and I think it needs stitches. What tests do I need to get done?
### Doctor: Yes, you're right. The first test we need to do is suturing your wound. We also need to do a wound care management to prevent any infection from occurring. Additionally, we need to perform a CAT scan of your head to check for any further injuries. As you fell, we need to check your blood alcohol level. Finally, we need to conduct a prothrombin time assay to check your blood clotting ability. Does that answer your question? We can also apply a splint to your injured area to prevent any further injury.
