I would take a look at this active thread (it talks about differences in LTC and hospital):
How differet working at Hostpial or Nursing Home as CNA??
Having worked at both, the hospital will give you far more 'technical' experience. You'll learn a lot about meds, machinery, procedures, various disease states, tests, vitals, etc. And, I think more importantly, you actually work with the nurses. In LTC, I hardly saw the nurses. In hospital, we would be assigned multiple nurses in a shift.
First thing is to get your foot in the door and get some experience.
