Question 1

During stationary cycling in a warm room, a woman with MS develops the same blurred vision and leg heaviness she experienced during an old relapse. Both resolve completely after 15 minutes of rest and cooling. She has no fever, infection symptoms, or new examination findings. What advice supports safe ongoing exercise?

Accepted Answer

Resume with cooling measures, shorter exercise intervals, and planned rest breaks.

Answer

Suspend aerobic exercise until repeat MRI excludes new inflammatory disease activity.

Answer

Arrange corticosteroid treatment before allowing her to resume the planned exercise program.

Answer

Replace aerobic exercise with passive stretching to prevent further demyelination during activity.

Question 2

A 29-year-old has a first typical episode of unilateral optic neuritis. MRI shows a short-segment lesion in the affected optic nerve and two ovoid periventricular lesions, with no other lesion locations involved. None enhances. Paired testing identifies CSF-restricted oligoclonal bands, and evaluation finds no better explanation. Under the 2024 McDonald criteria, which interpretation is correct?

Accepted Answer

The optic nerve and periventricular lesions establish dissemination in space; the positive CSF permits an MS diagnosis.

Answer

Only the periventricular region qualifies for dissemination in space; another non-optic CNS region must become involved.

Answer

Dissemination in space is established, but at least four affected regions are required when no lesions enhance.

Answer

The findings support MS, but a new lesion on follow-up MRI is mandatory before the diagnosis can be made.

Question 3

Baclofen titration has reduced a man's painful leg spasms, but he now needs assistance with a standing-pivot transfer he previously performed independently. Assessment shows that his knees buckle when the extensor tone is reduced; there are no new neurologic findings. He wants to preserve independent transfers while controlling nighttime spasms. Which change best matches that goal?

Accepted Answer

Reduce daytime baclofen under prescriber supervision and reassess transfers while retaining nighttime symptom control.

Answer

Maintain the current dose and replace standing-pivot transfers with a mechanical lift.

Answer

Continue titration until resting leg tone is normal before reassessing transfer ability.

Answer

Add daytime tizanidine to reduce residual tone and make the transfer less effortful.

Question 4

The first ocrelizumab infusion for a clinically stable adult with MS is scheduled in three weeks. The patient is due for the current season's inactivated influenza vaccine and has no vaccination contraindication. How should these treatments be timed?

Accepted Answer

Give the inactivated vaccine now and retain the planned infusion date.

Answer

Give the vaccine a week after the infusion to avoid delaying MS treatment.

Answer

Defer vaccination until B-cell recovery after ocrelizumab is stopped.

Answer

Vaccinate now and postpone the infusion until four weeks have passed.

Question 5

Severe bilateral optic neuritis and paraparesis develop in a 34-year-old with no established neurologic diagnosis. MRI shows a central spinal cord lesion spanning four vertebral bodies and a dorsal medullary lesion. Otherwise unexplained vomiting and persistent hiccups preceded the limb weakness. Which disorder most strongly fits this combination?

Accepted Answer

Aquaporin-4 antibody-associated neuromyelitis optica spectrum disorder

Answer

Myelin oligodendrocyte glycoprotein antibody-associated disease

Answer

Relapsing-remitting multiple sclerosis with brainstem and spinal cord involvement

Answer

Neurosarcoidosis affecting the optic nerves, brainstem, and spinal cord

Question 6

An employee with MS requests scheduled rest breaks from a U.S. employer covered by the Americans with Disabilities Act. The disability-related need is not obvious, so human resources requests medical documentation. The employee can perform the job's essential functions with the breaks. With the employee's authorization, what should the MS clinician provide?

Accepted Answer

A targeted report linking the MS-related functional limitations to the need for rest breaks.

Answer

The complete neurology record, including psychiatric notes and laboratory results unrelated to the requested breaks.

Answer

A statement naming the MS diagnosis but omitting how symptoms affect the employee's work.

Answer

An unrestricted fitness-for-duty certificate confirming that the employee can work without schedule changes.

Question 7

At two visits, a person with MS completes the Timed 25-Foot Walk using the same cane, instructions, and testing conditions. The mean of two trials increases from 8.0 seconds to 10.4 seconds. There is no acute illness or recent injury. Which conclusion combines the correct percentage change in walk time with a defensible clinical interpretation?

Accepted Answer

Walk time increased by 30%; investigate clinically meaningful slowing and its cause.

Answer

Walk time increased by 23%; investigate clinically meaningful slowing and its cause.

Answer

Walk time increased by 30%; this establishes conversion to secondary progressive MS.

Answer

Walk time increased by 30%; this remains within expected stable-patient test variability.

Question 8

Natalizumab has been withheld from a patient after 36 months of treatment because of three weeks of progressive word-finding difficulty and a new visual field defect. MRI shows a new juxtacortical lesion considered suspicious for progressive multifocal leukoencephalopathy. The initial CSF JC virus PCR from the local laboratory is negative. What does this result justify?

Accepted Answer

Continuing to withhold natalizumab and repeating CSF testing with an ultrasensitive JC virus PCR assay.

Answer

Treating with high-dose methylprednisolone for breakthrough MS and reassessing after completion of the steroid course.

Answer

Resuming natalizumab because a negative CSF PCR excludes active JC virus infection in the brain.

Answer

Using the serum JC virus antibody index to decide whether additional diagnostic testing is necessary.

Question 9

Visual acuity has recovered after MS-associated optic neuritis, but technically adequate pattern-reversal visual evoked potentials still show a delayed P100 peak with relatively preserved amplitude. What does the latency abnormality most directly reflect?

Accepted Answer

Slowed conduction through demyelinated visual pathways

Answer

The number of retinal ganglion cells permanently lost after the attack

Answer

Persistent disruption of the optic nerve blood-brain barrier

Answer

The amount of retinal nerve fiber layer thinning

Question 10

Urgency and frequent small voids are a woman's main bladder complaints. She has MS, and repeated post-void scans show approximately 350 mL remaining. Urine culture is negative. Urologic testing confirms detrusor underactivity without outlet obstruction. She has adequate hand function and cognition and is willing to learn catheterization. Select the preferred ongoing emptying strategy.

Accepted Answer

Teach clean intermittent self-catheterization with an individualized schedule.

Answer

Start oxybutynin to treat the urgency and frequency.

Answer

Use timed voiding with pelvic floor strengthening.

Answer

Place a long-term indwelling urethral catheter to maintain continuous bladder drainage.
