She also complains of chronic cough that has lasted for 10 years. Her symptoms are worsened even with light activities like climbing up a flight of stairs. She denies any weight loss, lightheadedness, or fever. Her medical history is significant for hypertension, for which she takes amlodipine daily. She has a 70-pack-year history of cigarette smoking and drinks 34 alcoholic beverages per week. Her blood pressure today is 12884 mm Hg. A chest X-ray shows flattening of the diaphragm bilaterally. Physical examination is notable for coarse wheezing bilaterally. Which of the following is likely to be seen with pulmonary function testing?? A: Increased FEV1: FVC and decreased total lung capacity, B: Decreased FEV1: FVC and increased total lung capacity, C: Increased FEV1: FVC and normal total lung capacity, D: Decreased FEV1: FVC and decreased total lung capacity, E: Normal FEV1: FVC and decreased total lung capacity,  <response>: This is a clinical vignette describing a 60-year-old woman with a history of chronic cough, worsening shortness of breath, and wheezing, as well as a significant smoking history. The question asks about expected pulmonary function test results. The history of chronic cough, dyspnea, and wheezing along with smoking history is most consistent with chronic obstructive pulmonary disease COPD. In COPD, there is airflow limitation due to damage to the airways and parenchyma. This leads to a reduced FEV1FVC ratio. Total lung capacity may be normal or increased in COPD depending on the degree of hyperinflation. B: Decreased FEV1: FVC and increased total lung capacity
