A client with obsessive-compulsive disorder (OCD) reports, "Thoughts stick in my mind and the rituals I use are stupid, but I cannot control them. People laugh at me, but they do not understand how awful it is. I am a burden to my family because I cannot hold a job. I do not know how much longer I can live this way." Which information is most important for the practical nurse (PN) to ask in response to the client's statements?
