16. A 29 year old woman is being discharged in 2 days form the hospital after her first psychotic break (paranoid schizophrenia). She is recently divorced and has been working as a legal secretary, although her work had become erratic, and her suspicious behavior was calling attention to herself at work. She will be discharged in her motherís care until she is able to resume working. Her mother is overwhelmed and asked the nurse how she is going to cope. ďShe has become so distant and she always takes thing the wrong way. I can hardly say anything to her with her misconstruing everything. She is very mad at me because I called 911 and had her admitted after she told me she was going to get justice back in the world by blowing up evil forces that have been haunting her life and then proceeded to try to run over her ex-husband, thinking he was the devil. She told me there is nothing wrong with her and I am concerned she wonít take her medication once she is discharge.

17. What are some of the priority concern that nurse could address in the hospital setting before she is discharge? How would you explain to the mother some of the symptoms that she is experience in? What suggestion could you give her to handle some of the immediate concerns? What issues could you bring up to the staff about her medication compliance? What would be some ways to deal with this issue? 4. What do you think of the prognosis for her? Support your hypothesis with data regarding influences on the course of schizophrenia.
