If there is something wrong immediately dial 911
Look around the environment to see if it’s clear and there is no sight of danger or weapons
If your gonna help the victim, apply gloves to prevent infection because the victim may have a open wound and anything unsanitary has a higher risk of infecting the wound.
Knowing your limit, if a hemorrhage occurs apply direct pressure and do not let go if the injured victim cannot do it themselves.
This may prevent shock.
If hemorrhage is severe apply a tourniquet (LAST RESORT).
Keep the victim calm as the adrenaline rush or shock may confuse the victim
Wait for the emergency crew
