Clean your own hands first. Wash your hands so that you don't introduce any infection into the wound. If it's bleeding, you want to stop the bleeding. Get a clean cloth. Get gauze. Get a menstrual pad. Put it on there and put pressure on there for a good 10 minutes. Once the bleeding has stopped, wash it out with soap and water. If there's any debris in there, you want to get that out. Any dirt or grit or anything like that, you want to get it out. If there's dirt or grit that you can't get out, that you've tried and tried and you still think there's stuff in there, you need to call the doctor. Otherwise, put antibiotic ointment on it. Cover it up with a bandage and keep it on. Change it every 24 hours unless it gets dirty or wet or it seeps through. With a scrape or a cut, if there's skin flapping over, if it's little, less than one centimeter by one centimeter, you can just put antibiotic ointment over it and cover it up. If it's bigger than that, go talk to your doctor. If your cut or your scrape is big, apply pressure and go talk to your doctor.
