Pheochromocytoma poses a disqualifying risk for commercial drivers primarily because it can cause what sudden event?
Answer: Paroxysmal hypertensive crisis causing incapacitation
Pheochromocytoma can trigger sudden, severe hypertensive crises with palpitations, sweating, and headache that may cause sudden incapacitation while operating a vehicle.
A driver with well-controlled type 2 diabetes managed by diet alone, with no complications, presents for a DOT physical. What certification is appropriate?
Answer: Certify for up to 2 years if otherwise qualified, with no additional restriction
Diet-controlled type 2 diabetes without complications or hypoglycemia risk does not preclude full 2-year certification if all other standards are met.
During urinalysis in the DOT physical, significant glucosuria (sugar in urine) should prompt the CME to take which action?
Answer: Investigate further for possible undiagnosed or uncontrolled diabetes before certifying
Significant glucosuria may indicate undiagnosed or poorly controlled diabetes, requiring further evaluation before the CME can safely make a certification decision.
Under FMCSA guidelines, which statement is true regarding commercial drivers with acromegaly?
Answer: Drivers may be certified if the condition is treated and secondary complications (e.g., hypertension, diabetes) do not disqualify them
Acromegaly itself is not automatically disqualifying, but the CME must evaluate and manage secondary conditions such as hypertension, diabetes, and sleep apnea that may affect qualification.
A commercial driver has been diagnosed with hyperparathyroidism and reports symptoms of fatigue and nephrolithiasis. What is the CME's primary safety concern?
Answer: Cognitive effects and sudden pain episodes (renal colic) causing incapacitation while driving
Hyperparathyroidism can cause cognitive impairment and sudden severe renal colic from kidney stones, both of which may result in unexpected incapacitation while driving.
When a CME suspects a driver may have undiagnosed type 2 diabetes based on examination findings, what is the most appropriate next step?
Answer: Defer certification and require fasting blood glucose or HbA1c testing before making a determination
When diabetes is suspected but undiagnosed, the CME should defer certification and require objective blood glucose testing to confirm or rule out the diagnosis before certifying.
