Review Question - QID 214431

A 42-year-old man presents to his primary care physician for a yearly physical exam. During the visit, he says that 1 month ago he had to find a new job and is very anxious about whether he will be able to support his family. He sometimes has trouble falling asleep at night because he has nightmares that he is unable to find a job and that his family will be forced to live on the street. He admits that he no longer spends much time with friends because he does not want to talk about how he was laid off from his previous job. He also says that he sometimes feels down because his new job pays far less than his previous job. On the weekends, he enjoys reading and going fishing at a local lake. On exam, his temperature is 98.6°F (37°C), blood pressure is 116/72 mmHg, pulse is 105/min, and respirations are 21/min. When asked about the elevated heart rate, he admits that he was just thinking about how they might not be able to pay the bills if their only car breaks down. Which of the following disorders is this patient most likely suffering from?
