I am a CPR instructor. You definately want the class for healthcare providers. (At least in Ohio) the "Family & Friends" class is not valid for people entering healthcare field either as aides or as LPN/RN. Also, the AHA is better b/c it lasts 2 yrs.
Usually, the school offers CPR as a part of their curriculum. Same with nursing homes, hospitals, etc. Are you sure you need to pay for it yourself?
Don't sweat the class too much. Although it is great to read it ahead of time and be familiar with the steps, the class will use a videotape and will have practices many, many times on a "dummy". Altho at 1st you feel "funny" doing the steps, by the end of the class you will be having fun and it will be easy! And if you fail the written test, you will be allowed to review the rationale and re-take a test.
You will probably also learn AED (Automatic External Defibrilator) and how to use it. Don't panic! It is very easy to do!
I have only failed ONE person in four years of teaching CPR. She just did not even try, and I went to all kinds of extremes to help teach her, because I knew it would mean she could not stay in LPN class. But she had the nerve to say "I don't see what the big deal about it is...I was able to pass the written test so it is obvious I know what to do. I don't know why you make such a big deal out of knowing it anyway." (She could not pass the demo on the dummy)
*HELLO!!!**** And she wants to be a NURSE????
Good luck! You will do fine!!!
