Single choice
A23-year-old university student has lost interest in his master's degree program. His two friends who bring him to the psychiatrist say he has been isolating himself in his room and has covered all electrical appliances and outlets with duct tape claiming that "electromagnetic waves are disturbing the microchip in my brain." He acknowledges that he once took a medication for the same problem with the "microchip," but then he became unbearably restless, could not sit still, and felt that he was "crawling" inside. According to the patient's psychiatric symptoms, select the most appropriate medication. Presume no medical problems other than those mentioned.
