I think it depends how much care the individual patient needs. A year ago I spent nine nights on Female Orthopaedic with a broken hip and wrist (the right, my dominant one as luck would have it). Apart from a bed bath the morning after my THR surgery, I was responsible for washing myself. I would request towels, fresh gowns etc. and a nurse would bring a bowl of hot water, fetch my toiletries bag from my locker, and draw the curtains round so I could get on with it.
I had a shower a couple of times during my stay, when DH would help me, pushing me in a wheeled shower chair into the bathroom and helping me undress and dress again etc.
My bedding was changed about every three days, which I think was fine, as I wasn't soiling it, so it didn't need changing every day. Again, I think that would depend on the individual patient's circumstances.
The ward was incredibly busy, and even though I could just about haul myself up the bed and to sitting with my left hand, I was very obviously encouraged to be as independent as possible. The OP's daughter clearly needs a lot more care which doesn't seem to be forthcoming, which is very concerning. Although for years now, spouses or relatives etc. have been encouraged to help provide basic care with washing etc. presumably to take the pressure off already short staffed wards. Personally, I'd rather be helped by DH than a nurse, but other patients need more care from nurses that they're not getting, which is very worrying.
