The following are multiple choice questions (with answers) about medical knowledge.   **Question:** A 72-year-old man presents to his primary care physician with a 6-month history of shortness of breath. He says that he used to enjoy playing golf with his friends but now he cannot walk for long enough to play. The shortness of breath is now starting to complicate his ability to get around in daily life. His past medical history is significant for diabetes, hypertension, and early stage prostate cancer that was removed 10 years ago without recurrence. He has smoked 1 pack per day for the past 55 years and drinks about 6 drinks per week. On presentation he is found to be breathing with pursed lips. Physical exam reveals decreased breath sounds on auscultation, increased chest diameter, and hyperresonance to percussion. Which of the following findings would most likely be seen in this patient?   (A) Decreased residual volume and decreased 1 second forced expiratory volume   (B) Decreased residual volume and increased 1 second forced expiratory volume   (C) Increased residual volume and decreased 1 second forced expiratory volume   (D) Normal residual volume and decreased 1 second forced expiratory volume
