Lungs Pulmonary Function Test in an Asthmatic

A 30-year-old patient with a history of mild persistent asthma (baseline peak expiratory flow rate of 85%) presents to the emergency department (ED) with shortness of breath and wheezing not relieved by her albuterol inhaler for the past 12 hours. She was able to tolerate pulmonary function tests and a set was performed.
Which of the following is the most likely test result?
(A) Decreased FEV1, normal/increased FVC, decreased FEV1:FVC ratio, with postbronchodilator FEV1 increased by 13%
(B) Decreased residual volume and total lung capacity
(C) Increased FEV1, increased FVC, normal FEV1:FVC ratio
(D) Increased residual volume, increased total lung capacity, increased FEV1
(E) Normal FEV1, decreased FVC, increased FEV1:FVC ratio
