Question: Which of the following findings on pulmonary function testing is required for the diagnosis of an “obstructive” pattern?
Question: A 51 year-old woman with no prior tobacco use presents to her primary care provider for evaluation of chronic cough and dyspnea over a several month period. She is referred for pulmonary function testing which reveals FEV1 1.6 L (59% predicted), FVC 1.8 L (60% predicted) and FEV1/FVC 0.89. Her total lung capacity is 3.0 L (60% predicted). Which of the following statements correctly characterizes the observed abnormality?
Question: During an evaluation for increasing dyspnea over a several week period accompanied by night sweats and fevers, a 30 year-old man is found to have lymphadenopathy encasing the intrathoracic trachea above the carina. The airway lumen is narrowed by this lymphadenopathy and does not vary in size over the respiratory cycle. Which of the following findings would you expect to see when you evaluate the flow-volume loop obtained during a forced vital capacity maneuver?
Question: A 36 year-old woman is sent to the pulmonary function testing laboratory for evaluation of worsening dyspnea on exertion. Her testing reveals an FEV1 55% predicted, FVC 60% predicted, FEV1/FVC 0.82, TLC 70% predicted and a DLCO 85% predicted. Which of the following diagnoses would be consistent with the observed pattern on her pulmonary function tests?
Question: A 35 year-old woman presents for evaluation of dyspnea on exertion over a several month period with an otherwise unremarkable review of systems. She is sent for complete pulmonary function testing which reveals an FEV1 85% predicted, FVC 90% predicted, FEV1/FVC 0.85, TLC 88% predicted and DLCO 45% predicted. There is no bronchodilator response. The observed pattern of results would be consistent with which of the following categories of disease?
Question: A 60 year-old man presents for evaluation of decreasing exercise tolerance. Pulmonary function testing reveals a decreased total lung capacity with a normal diffusion capacity for carbon monoxide. Which of the following studies would be most appropriate to order to follow-up these test results?
Question: Which of the following results would be consistent with a bronchodilator response following administration of a short-acting bronchodilator during pulmonary function testing?
Question: A patient has pulmonary function testing performed and is found to have a low FEV1 and FVC with a preserved FEV1/FVC ratio, a reduced total lung capacity and a decreased DLCO. This pattern would be consistent with which of the following diagnoses?
Question: A patient can be described as having ‘air trapping’ on their pulmonary function testing when which of the following findings is present?
Question: A 58 year-old man who formerly worked as a hard-rock miner presents to his primary care physician with dyspnea on exertion. She orders pulmonary function tests, which show a mixed obstructive-restrictive defect. Which of the following sets of results on pulmonary function testing would be most consistent with this pattern?
