I'm about to finish my CNA course so I can get some experience while in nursing school (RN).. but I most DEFINATELY don't want to work with the elderly. I have knee issues and cannot handle the physical strain of lifting and moving dead weight, so I'm considering going ahead and getting my MA. What I'm wondering is if it would be worth it. Do MA's do the same work as CNA. Money isn't an issue, it's more about the physical labor. I'm wanting to work in a Dr.'s office. It'll cost an additional $1500 and will take another 18 weeks (I have to get my phlabotomy and EKG tech first).
