Question 2 of 5
A 34-y old lifelong nonsmoking male presents for evaluation of dyspnea, fatigue, and nonproductive cough which is worse in the evening. His symptoms have been ongoing for the last 6 months. He is an auto mechanic working in an autobody shop for the last 4 years. He believes his symptoms are work related. Medical history is otherwise negative and he is on no medications. Physical exam and vital signs are normal. CXR and spirometry are normal. What is the most appropriate next step?
