1. Remain calm.
2. Lean forward. If there is blood in your mouth, spit it out; do not swallow it.
3. Apply 3 sprays of decongestant nose spray, such as Afrin, into the side that is bleeding.
4. Pinch the soft part of your nose shut.
5. Pinch the nose for 10 minutes. Use a clock to keep track of time. Resist the urge to peek after a few minutes to see if your nose has stopped bleeding.
6. After 10 minutes, let go of your nose. If it is still bleeding, soak a cotton ball with the nose spray. Place the cotton ball into the bleeding nostril and pinch for 10 minutes. Again, use a clock to time it.
7. Once bleeding has stopped, do not blow your nose for 2 days.
That's some sound advice....just not for a bullet wound to the head
