D．Generalized anxiety disorder is characterized by anxiety that lasts longer than 6 months.
参考答案：D
解析：Constant patterns of anxiety that affect the client for more than 6 months and interfere with normal activities are characteristic of generalized anxiety disorder. Frequently, pharmaceutical therapy with benzodiazepines can help. Clients having regular obsessions are probably suffering from obsessive-compulsive disorder. Nightmares and flashbacks are typical symptoms of posttraumatic stress disorder.
