A 57-year-old man presents to his primary care
physician complaining of shortness of breath
that has been worsening over the past 6
months. Initially, he had dyspnea on exertion
but this evolved into dyspnea at rest, as well as
a nonproductive cough for the last month. He
denies weight loss, fevers, or night sweats. On
further review of systems, he complains of pain
and swelling in his hands. He also notes that
his body feels stiff in the morning. He has no
other significant past medical history and is
taking no medication except for occasional
ibuprofen for his hand pain. He has never
smoked. On physical examination, he has
crackles at the lung bases bilaterally. He has
enlarged metacarpophalangeal joints bilaterally. They are red, warm, and tender to palpation. He also has slight ulnar deviation of the
fingers. What will pulmonary function tests on
this patient most likely show?
