The driver reports of history of COPD and that he smokes a pack and a half of cigarettes daily. He has been treated by a pulmonologist for a few years now but insists he is able to drive safely. He lists that he is taking Spiriva daily and his "water pill" which he cannot remember the name of, for high blood pressure. His examination reveals notable wheezing in all lung fields upon auscultation, a BMI of 34.23, and the rest of his examination is unremarkable. The examiner should:
a) Request a Sleep Study.
b) Request a Pulmonary Function Test or recent Test results.
c) Certify the driver for 1 year.
d) Certify the driver for 2 years.
