First off, since you are severely bleeding we must call 911. Since I know that the scene is safe, the next step is to obtain consent. "My name is Carol and I have taken a number of first aid classes and courses. Can I help you?"
"Yes!! I give you my consent!"
Now I will put on gloves to prevent any germs spreading! I will also apply some sterile dressing to the wound. In addition, I will also apply some pressure.
Now that I have put on gloves, applied sterile dressing, and applied pressure to the wound, I will put on a roller bandage. I will wrap it around you arm multiple times to ensure it is secure. After I wrap it up, I will tape it to secure it.
"Thank you so much."
Now we will continue to apply pressure. Although, since you bled through the bandages, I will apply more.
I got transported to the hospital and now that I have been treated, I feel much better!! I am very lucky that Carol, the bystander was there to help!
