Answer:
The first thing I would do is C. Call 911. This is a major safety precaution because, calling 911 will save you time when you are unable to perform other helpful acts, such as CPR. Calling 911 initially and ten handling the situation, or at least doing it at the same time, will ensure you are using your time as wisely as possible.
I learned in my health course to never begin CPR before calling 911, and if someone is around, have a bystander call 911, but this is in an effort to save as much time as possible [response time specifically].
