When reviewing the chart of a client with long standing lung disease, the nurse should pay close attention to the results of which pulmonary function test?
Correct answer
C
Rationale
The FEV1/FVC ratio indicates disease progression. As COPD worsens, the ratio of FEV1 to FVC becomes smaller. Answers A and B reflect loss of elastic recoil due to narrowing and obstruction of the airway. Answer D is increased in clients with obstructive bronchitis.
