Shelby,

From my own experience working at a CNA before starting PA school, my responsibilities included helping patients or residents with eating, toileting, bathing and other hygiene such as shaving, checking vital signs and blood glucose, and basic documentation on what I did during shifts. There may well be variations in your responsibilities depending your level of experience, type of work setting, etc., and you still certainly be given a list of responsibilities as part of interview or orientation/training process. I hope this helps.

Good luck!
