Dad just moved from a large unit on the assisted living floor to a much smaller room memory care. He will be benefiting from the higher ratio of staff to residents and more appropriate programing. However , he seems to be getting trapped by his walker as he attempts to open the door. Even if he does manage to open the door, it falls back on his arm as he walks put leaning on the walker. His skin is fragile and bruises and bleeds easily. The facility want to solve the problem by propping the door open. But other residents are wandering about disoriented, so this doesn't seem like a good long term fix. Any ideas?
