NRCME Neurological Disorders Evaluation 3 — Questions and Answers
Question 1: A driver had a transient ischemic attack (TIA) 4 months ago with full neurological recovery. What is the minimum waiting period before recertification as a CMV driver per FMCSA guidelines?
- No waiting period if neurologically intact
- At least 1 year symptom-free after TIA (Correct answer)
- At least 6 months with neuroimaging clearance
- At least 2 years with specialist clearance
Correct answer: At least 1 year symptom-free after TIA
FMCSA guidance recommends a minimum 1-year waiting period after a TIA before recertification, with neurological clearance confirming no residual deficits.
Question 2: Which of the following best characterizes narcolepsy in the context of FMCSA medical certification?
- Certifiable if symptoms are controlled with stimulant medication
- Disqualifying condition regardless of treatment (Correct answer)
- Certifiable after 2 years without cataplexy episodes
- Certifiable with a 1-year medical certificate if on sodium oxybate
Correct answer: Disqualifying condition regardless of treatment
Narcolepsy is considered a disqualifying condition for CMV drivers under FMCSA regulations due to unpredictable sleep attacks and cataplexy that cannot be reliably prevented.
Question 3: During neurological evaluation of a CMV driver, the Romberg test is performed. A positive Romberg sign (marked sway with eyes closed) is most indicative of:
- Cerebellar ataxia
- Proprioceptive or posterior column dysfunction (Correct answer)
- Vestibular dysfunction only
- Upper motor neuron disease
Correct answer: Proprioceptive or posterior column dysfunction
A positive Romberg sign indicates loss of proprioceptive input, reflecting posterior column dysfunction, as the patient can compensate with visual input but not without it.
Question 4: A driver with well-controlled multiple sclerosis (MS) in remission for 3 years is applying for CMV certification. The examiner should:
- Certify for a standard 2-year period without restriction
- Disqualify because MS is an absolute disqualifying condition
- Evaluate current neurological function and certify only if no disqualifying deficits are present (Correct answer)
- Defer to the state licensing agency for determination
Correct answer: Evaluate current neurological function and certify only if no disqualifying deficits are present
MS is not an automatic disqualifier; the examiner must assess current functional status, and if no disqualifying deficits exist, certification may be granted with appropriate follow-up.
Question 5: Which medication used for migraine prophylaxis is most likely to cause side effects that could impair driving performance and should be discussed during NRCME evaluation?
- Topiramate (cognitive slowing, word-finding difficulty) (Correct answer)
- Amitriptyline at 10 mg at bedtime
- Magnesium supplementation
- Riboflavin (vitamin B2)
Correct answer: Topiramate (cognitive slowing, word-finding difficulty)
Topiramate is associated with cognitive slowing and word-finding difficulties that can impair driving, requiring careful assessment during CMV medical evaluation.
Question 6: A commercial driver presents with carpal tunnel syndrome causing significant hand weakness and thenar atrophy. The appropriate NRCME certification decision is:
- Certify with no restriction as the condition is peripheral
- Certify only if grip strength testing is normal bilaterally
- Evaluate functional ability to safely operate a CMV; disqualify if ability is impaired (Correct answer)
- Automatically disqualify due to the neurological nature of the condition
Correct answer: Evaluate functional ability to safely operate a CMV; disqualify if ability is impaired
The examiner assesses whether carpal tunnel syndrome causes functional impairment sufficient to prevent safe CMV operation, not whether a neurological condition exists.
Question 7: Which of the following is the most appropriate initial screening tool for cognitive impairment during a neurological evaluation for CMV certification?
- Full neuropsychological battery
- Montreal Cognitive Assessment (MoCA) or Mini-Mental State Examination (MMSE) (Correct answer)
- Brain MRI with gadolinium
- EEG with sleep deprivation protocol
Correct answer: Montreal Cognitive Assessment (MoCA) or Mini-Mental State Examination (MMSE)
Brief validated cognitive screening tools such as the MoCA or MMSE provide a rapid, standardized assessment of cognitive function appropriate for initial screening in a medical exam setting.
