Not sure about type of care for Mom

I have been looking at assisted living for my mom who is 75 years old, very frail physically and suffering with Parkinson's disease. Her Parkinson's is mild, but she has major problems with her blood pressure and experiences dangerous highs and lows. She occasionally experiences episodes of syncope. She is currently living at her home two hours from me and has 24/7 caregiving from a RN and home health aide.

Last night she experienced an episode of syncope and passed out on her way to the bathroom. The nurse caught her and laid her down, she came to and said she still had to go, then passed out on the toilet again. The nurse was holding her upright. I am scared of what would have happened if the nurse hadn't been there to help. In assisted living, there are periodic checks but not someone in the apartment all the time.

Is assisted living an appropriate placement with a situation like this? Thank you.
