Answer to Question 1

D
A decreased FEF25-75 would be found because the patient's secretions will reduce expiratory air flow. Air trapping will result in an increased RV/TLC ratio. PEFR will be reduced because of airway secretions.

Answer to Question 2

A
In the absence of trauma or surgery, blood in the pleural fluid most likely results from malignant disease. A pulmonary embolization and infarction may also cause blood in the pleural fluid.
