To stop a nosebleed, the most effective steps are to stay calm, sit up straight, and lean the head slightly forward to avoid swallowing blood. Pinch the soft part of the nose just below the nasal bone firmly using the thumb and finger for about 10 to 15 minutes without releasing the pressure. Breathe through the mouth during this time. Avoid lying down, tilting the head back, or inserting anything into the nose. After bleeding stops, avoid blowing or picking the nose for several hours to prevent re-bleeding. If the bleeding does not stop after 10 to 15 minutes of continuous pressure, seek medical attention.

Here is a concise summary:
