The FEV1 on a pulmonary function test is 39% pre-bronchodilator and 39% post-bronchodilator on a patient admitted to the hospital with COPD and pneumonia. Which of the following would you recommend never?
1. Continue bronchodilator therapy because it increases sputum production that allows patient to expectorate that pneumonia
2. Discontinue bronchodilator therapy because the PFT verifies it has no benefit to the patient
3. Continue bronchodilator therapy and add mucomyst to help patient expectorate the pneumonia
4. Order a second PFT because there must have been a technical error to show for the lack of benefit
