Linx, what led you to come to this forum? Do you, or someone who is close to you, have a liver disease? I welcome you to start a new post if you, or someone close to you, has liver disease.
Allie, is she still on Lactulose? If so, I would have to think that it needs to be increased. You might request visiting nurses when she is released, if that is something that is available over there. They can keep an eye on her. I know your concern is that she will drink again once she gets home, and the truth is that she probably will. You can ask about them ordering a walker for her to use at home, if the one she has been using hasn't been purchased for her. The danger is in her falling and knocking out the hip replacement. She also needs a chair or bench for the tub or shower and a handheld shower attachment. Make sure that everything she needs is at waist-high access, as she can't bend down low nor climb. She also will need a riser that goes over the toilet seat to make it higher. Speak to the PT at the hospital about all this and to order it for her before she is discharged. These are things that you actually CAN do. Keeping her from drinking or forcing her to go to rehab are things you CANNOT do.
Yes, Allie, she should be using the long-handled grasper. I have one and use it all the time. Where is she getting all the chocolate from? I mentioned in another thread about the effect alcohol has on the brain--and the brain does not regenerate. This happened to my own mother. At the time of her death, she barely knew her own name.
It appears that discharge for your mum is imminent. Please do ask about getting her some home nursing care. If she doesn't at least have that, I'm afraid she is going to make a rapid decline...particularly if she continues to drink. I'm sure that in her current state of mind, she doesn't think anything is wrong with her.
