Answer:
Call first aid, Activate EMS(Emergency Medical Services).
Step-by-step explanation:
After checking your surroundings and making sure that everything is safe, you shake and shout(check for responsiveness). If it is safe to say that the victim isn't showing any signs of response, you immediately call 911. If there is someone nearby, ask them to call and then get back to you saying that they have reached out and EMS is on their way.
