I will answer your questions in reverse order.. I don't give medical advice to neighbors or acquaitances. I am not a doctor. The only advice I give is, "See your primary physcian or go to the ER if you are concerned." Heck that's the advice I give my own kids.. What good would it do me to give them a diagnosis if I can't treat them???
As for stopping at the scene. You are protected by the Good Samaritan laws.. Your textbook probably addressing that issue.
