Answer 1

I would say The first step would be to get help or in the case you could help to prevent more harm do that.

Answer 2

Well, it depends on what the life-threatening situation is. If they are bleeding out of a wound, apply pressure to it. If they were stabbed, do NOT remove the knife (or whatever penetrated them). Apply CPR in many cases as well. When you have the time make sure to call for help!!
