A nurse is caring for a client who has depression and states, "A government agency is attempting to capture me." The nurse should identify that the client is experiencing which of the following?

A. Confusion involves disorientation or difficulty understanding surroundings, not fixed false beliefs. B. Inappropriate guilt is a symptom of depression but does not involve false beliefs about external control. C. Delusions are fixed, false beliefs that are not based in reality, such as thinking a government agency is trying to capture the person. This is a paranoid delusion, often seen in psychotic disorders or severe depression with psychotic features. D. Mania is characterized by elevated mood, hyperactivity, and impulsive behavior, not paranoid or persecutory thoughts.
