NRCME Neurological Disorders Evaluation 2 — Questions and Answers
Question 1: A commercial driver reports a single unprovoked seizure 6 months ago with no recurrence on medication. Under FMCSA guidelines, what is the appropriate certification decision?
- Certify if seizure-free for 5 years off medication
- Disqualify; a single seizure with diagnosis of epilepsy is disqualifying (Correct answer)
- Certify with a 1-year card since 6 months have passed
- Certify only if EEG is normal
Correct answer: Disqualify; a single seizure with diagnosis of epilepsy is disqualifying
FMCSA regulations disqualify any driver with a diagnosis of epilepsy or a seizure disorder, regardless of medication control or recurrence interval.
Question 2: Which feature on neurological examination is MOST associated with a peripheral vestibular disorder rather than a central cause of vertigo?
- Direction-changing nystagmus
- Nystagmus that does not fatigue with repeated testing
- Unidirectional nystagmus that suppresses with visual fixation (Correct answer)
- Vertical nystagmus
Correct answer: Unidirectional nystagmus that suppresses with visual fixation
Peripheral vestibular nystagmus is typically unidirectional, horizontal or horizontal-torsional, and suppresses with visual fixation, distinguishing it from central causes.
Question 3: A truck driver is diagnosed with obstructive sleep apnea and placed on CPAP therapy. After how long of documented adequate CPAP compliance may the NRCME examiner consider recertification?
- Immediately upon CPAP initiation
- After 1 week of CPAP use
- After demonstrating effective treatment, typically at least 4 weeks with compliance data (Correct answer)
- After 6 months of CPAP use only
Correct answer: After demonstrating effective treatment, typically at least 4 weeks with compliance data
FMCSA guidance recommends at least 4 weeks of documented CPAP compliance with objective data showing effective therapy before recertification.
Question 4: Which of the following best describes the neurological basis for syncope that may disqualify a CMV driver?
- Transient focal cerebral ischemia lasting less than 24 hours
- Sudden transient loss of consciousness due to global cerebral hypoperfusion (Correct answer)
- Loss of consciousness lasting more than 30 minutes
- Focal weakness without loss of consciousness
Correct answer: Sudden transient loss of consciousness due to global cerebral hypoperfusion
Syncope is a transient loss of consciousness caused by global cerebral hypoperfusion, and recurrent unexplained syncope is disqualifying for CMV drivers.
Question 5: A driver with Parkinson's disease is evaluated for CMV certification. Which of the following is most likely to result in disqualification?
- Mild resting tremor controlled with levodopa
- Presence of rigidity on examination
- Medication-induced orthostatic hypotension causing dizziness (Correct answer)
- Diagnosed within the last 12 months
Correct answer: Medication-induced orthostatic hypotension causing dizziness
Medication-induced orthostatic hypotension in Parkinson's disease poses an immediate safety risk due to potential sudden loss of control, making it a disqualifying condition.
Question 6: Under FMCSA standards, which vision requirement is specifically assessed to evaluate neurological field defects in CMV drivers?
- Near visual acuity of 20/40 in each eye
- Horizontal visual field of at least 70 degrees in the horizontal meridian in each eye (Correct answer)
- Color vision testing with Ishihara plates
- Stereopsis testing with the Randot stereotest
Correct answer: Horizontal visual field of at least 70 degrees in the horizontal meridian in each eye
FMCSA requires at least 70 degrees of horizontal visual field in each eye, which helps detect hemianopias and other neurological field defects.
Question 7: A driver reports numbness and tingling in both feet for 6 months, with reduced ankle reflexes. The most likely etiology requiring further neurological evaluation before CMV certification is:
- Lumbar spinal stenosis
- Peripheral neuropathy (Correct answer)
- Cervical myelopathy
- Restless legs syndrome
Correct answer: Peripheral neuropathy
Bilateral distal sensory symptoms with reduced reflexes are classic for peripheral neuropathy, which must be evaluated for severity and functional impact before certifying a CMV driver.
