Mandi - I am so sorry for what you are going through. I hope the nurse can talk with him AND evaluate what's going on. Not to give Dennis any excuses, but it could be that the combination of meds plus his health status has pushed him to the point that he is not psychologically stable. If his nurse has any doubts, his primary physician should be consulted. I remember when my father was very ill and he did the same thing to me one day in the hospital - shouted at me and tried to hit me. I ended up sobbing in the hall, but it was all a result of the medication he was on plus his health issues. I know you are doing your best and it must be so difficult for you. Wish I could do more to help...
