What questions should I prepare for my mother's nursing home meeting?

My mother, who is 97, fractured her hip and has been in a rehab/NH for the past 3 weeks. I am out of state, but have visited her there 3 or 4 times. She seems to be doing well in physical therapy with a walker. I have some issues, such as her phone being out of order for about 5 days, her laundry being stuffed in a plastic bag in her closet and not being done, as I had requested. I also put money in her account there for her to get her hair done, but nobody has contacted her. But these are housekeeping problems. The NH doc, with whom I have spoken, seems aloof and arrogant. I was told (by her) that she will not be at this meeting. That seems unusual to me. Should I contact my mother's assigned social worker at the place and let them know what the doc told me? What other questions should I be asking or be prepared to answer? My mom is mentally stable, and will also be at the meeting. She was living at an independent/AL facility prior in the independent part. I am assuming she will need an aide to be with her for a while right after she gets out. Any suggestions for me about what to expect at the meeting would be great. I was told in the "there will be a care meeting" letter that the meeting will be kept to 15 minutes because other residents' meetings are also scheduled for that day. 15 minutes does not seem like much time. Is this the norm?
