Question 1

Pheochromocytoma poses a disqualifying risk for commercial drivers primarily because it can cause what sudden event?

Accepted Answer

Paroxysmal hypertensive crisis causing incapacitation

Answer

Pheochromocytoma can trigger sudden, severe hypertensive crises with palpitations, sweating, and headache that may cause sudden incapacitation while operating a vehicle.

Question 2

A driver with well-controlled type 2 diabetes managed by diet alone, with no complications, presents for a DOT physical. What certification is appropriate?

Accepted Answer

Certify for up to 2 years if otherwise qualified, with no additional restriction

Answer

Diet-controlled type 2 diabetes without complications or hypoglycemia risk does not preclude full 2-year certification if all other standards are met.

Question 3

During urinalysis in the DOT physical, significant glucosuria (sugar in urine) should prompt the CME to take which action?

Accepted Answer

Investigate further for possible undiagnosed or uncontrolled diabetes before certifying

Answer

Significant glucosuria may indicate undiagnosed or poorly controlled diabetes, requiring further evaluation before the CME can safely make a certification decision.

Question 4

Under FMCSA guidelines, which statement is true regarding commercial drivers with acromegaly?

Accepted Answer

Drivers may be certified if the condition is treated and secondary complications (e.g., hypertension, diabetes) do not disqualify them

Answer

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.

Question 5

A commercial driver has been diagnosed with hyperparathyroidism and reports symptoms of fatigue and nephrolithiasis. What is the CME's primary safety concern?

Accepted Answer

Cognitive effects and sudden pain episodes (renal colic) causing incapacitation while driving

Answer

Hyperparathyroidism can cause cognitive impairment and sudden severe renal colic from kidney stones, both of which may result in unexpected incapacitation while driving.
