Can siblings have a POA revoked due to negligent caretaking?

Question Details: One of my sisters has a POA for my dad's medical/healthcare. He has a CNA come to the house to prepare meals, clean house, wash clothes, give baths and dress him. My other siblings and I have noticed that these things are not being done. We believe he has to prepare his own meals which must be cooked in the microwave which sometimes is not cooked completely and are cold, the house stinks of urine, his clothes smell of urine and feces and from looks of his pants you can see that they have been that way for several days. He also smells and by monitoring the bathroom the shower sometimes is not used for several days week. We often go to see him and he is not even dressed at noon and this is a function that he just cannot do. We feel he would do better in a home where these issues would be taken care of but there is resistance. We have also tried to address this issues with him but he becomes defensive about it but this may be due to the fact that the CNA is his stepdaughter. I do not want my family to be divided due to this problem.
