Problem:
In a patient with symptoms suggestive of chronic obstructive pulmonary disease (COPD), the nurse practitioner knows that: a. Symptoms should be fully reversible after administration of a bronchodilator, b. An airflow limitation <0.7 before a bronchodilator dose indicates normal airflow. c. Postbronchodilator FEV1/FVC ratio <0.7 indicates COPD. 4. A peak expiratory flow measure is better than spirometry to assess air flow limitation.
