NRCME Neurological Disorders Evaluation 5

Question 1

Which of the following is the FMCSA standard for visual acuity that must be met in each eye for CMV certification, with or without corrective lenses?

Accepted Answer

20/40 in each eye

Answer

FMCSA requires distant visual acuity of at least 20/40 in each eye, with or without corrective lenses, as part of the physical qualification standards.

Question 2

A driver with a spinal cord injury at the C6 level is seeking CMV certification. Which functional deficit is MOST likely to impair their ability to safely operate a commercial vehicle?

Accepted Answer

Impaired hand and grip strength affecting steering wheel control

Answer

C6 spinal cord injury affects wrist extension and hand grip, directly impairing the ability to safely steer and control a commercial vehicle.

Question 3

During neurological examination, a driver demonstrates inability to perform rapid alternating movements (dysdiadochokinesia). This finding is most consistent with:

Accepted Answer

Cerebellar pathway dysfunction

Answer

Dysdiadochokinesia reflects cerebellar dysfunction affecting the coordination of rapid repetitive movements, distinct from the rhythmic slowness of basal ganglia disease.

Question 4

A driver presents with new-onset daily headaches, papilledema on fundoscopic exam, and mild cognitive slowing. The NRCME examiner should:

Accepted Answer

Immediately defer certification and refer for urgent neurological evaluation

Answer

Papilledema indicates elevated intracranial pressure, which with cognitive changes and new headaches suggests a serious intracranial process requiring urgent evaluation before any certification.

Question 5

Which of the following drivers with stroke history may be considered for CMV certification under FMCSA guidelines?

Accepted Answer

A driver 14 months post-stroke with complete neurological recovery and neurologist clearance

Answer

After stroke, a minimum 1-year waiting period is recommended, and certification may be considered if there is complete neurological recovery with specialist clearance confirming no disqualifying deficits.
