The following are multiple choice questions (with answers) about medical knowledge.   **Question:** A 48-year-old man seeks evaluation at a clinic with a complaint of breathlessness for the past couple of weeks. He says that he finds it difficult to walk a few blocks and has to rest. He also complains of a cough for the past 3 months, which is dry and hacking in nature. The medical history is relevant for an idiopathic arrhythmia for which he takes amiodarone daily. He is a non-smoker and does not drink alcohol. He denies any use of illicit drugs. The vital signs are as follows: heart rate 98/min, respiratory rate 16/min, temperature 37.6°C (99.68°F), and blood pressure 132/70 mm Hg. The physical examination is significant for inspiratory crackles over the lung bases. An echocardiogram shows a normal ejection fraction. A chest radiograph is performed and shown below. Which of the following findings will most likely be noted on spirometry?   (A) Decreased FEV1 and normal FVC   (B) Decreased FEV1 and FVC with decreased FEV1/FVC ratio   (C) Decreased FEV1 and FVC with normal FEV1/FVC ratio   (D) Increased FEV1 and FVC
