Outside of combat, you are not likely to need to move the person until qualified help arrives, and they took the IV stick out of the CLS course...
So that pretty much leaves you rendering first aid, which is hard to screw up. I advise my troops to do what is necessary to preserve life and mitigate suffering, in that order. But if anyone else on scene says they are a Doc, RN, or EMT...let them have it!
