Review Question - QID 214279

A 20-year-old man presents to the university mental health clinic with a 4-month history of increased worrying. He says that starting this semester, he began fearing that he was forgetting something whenever he left his dorm room. Over time, this fear has progressed to the point where he needs to check his backpack over 20 times before leaving for class. He does not want to have these thoughts but says that he cannot help himself. He finally came to be evaluated because these behaviors have started making him late for classes and tests. He has the same problem when he prepares for social encounters; however, he says that he enjoys being with friends when he finally arrives. Which of the following drugs is the most appropriate treatment for this patient?
