What care is normally provided? Are there different services avalible?

I was not sure where to put this question so I am putting it in the general section.

I just want to get an idea of what to expect to be provided in general home/health care for seniors to make sure everything will be covered that my mother will need help with. She lived alone but my sister recently started staying with her a few times a week to help her out. I am not sure she is to the point where she needs round the clock care but she does need someone to help out daily.
