Answer:
Put the cut portion in vertical upward position and cover it with clean tissue or cloth.
Explanation:
At first to minimize the bleeding from wrist we need to raise the wrist up and then apply pressure by clean tissue or cloth. Wrap the tissue/clothe around the wrist. If blood is soaking through the material wrapped, don't remove the wrap but pot more tissues/cloths around the wrap and continue to apply the pressure. The hand should be kept raised at a level more than the level of heart of that injured person. Due to continuous pressure of the wrapping material the bleeding will stop in around 5-8 minutes.
