The medical examiner notes that a driver is taking Metformin for the treatment of diabetes (and has an A1c of 6.5), Crestor to reduce serum cholesterol levels, and Antabuse. He reports no side effects from any of the medications. The rest of the examination is unremarkable. The examiner should:

a) Disqualify the driver until additional information is obtained.
b) Request clearance from prescribing physician for all medications.
c) Certify the driver for 1 year.
d) Certify the driver for 2 years.

The medical examiner should c) certify the driver for 1 year, considering the medications being taken and the absence of side effects, allowing for regular monitoring of the driver's condition and medication response.

Explanation:

The question asks about the appropriate action a medical examiner should take when evaluating a driver who is taking multiple medications, including Metformin, Crestor, and Antabuse, and reports no side effects, with the rest of the examination being unremarkable.

Given this information, the key considerations include the potential impact of these medications on driving, planning to drive, or participating in other activities requiring skill, coordination, and alertness. However, based solely on the information provided and without specific indicators of impairment or risk factors beyond controlled diabetes and managed cholesterol, the medical examiner might opt for a conservative approach to ensure public safety and the driver's well-being which typically involves closer monitoring.
