Original Practice Study Guide
1. Following an ischemic stroke involving the left middle cerebral artery, which finding is most
consistent with injury to the dominant cerebral hemisphere?
A) Isolated loss of vibration sense in both feet
B) Aphasia with right-sided weakness
C) Bilateral lower-extremity weakness without language change
D) Left-sided neglect with left hemiparesis
Correct Answer: Aphasia with right-sided weakness
Rationale: The dominant left middle cerebral artery supplies cortical regions involved in language as well as
motor and sensory areas for the contralateral face and upper limb. Aphasia with right-sided weakness therefore
fits this vascular territory. Neglect is more typical of a nondominant right hemispheric lesion, while bilateral leg
weakness suggests a different distribution.
2. A transient episode of focal neurologic dysfunction resolves completely within 30 minutes and
diffusion-weighted imaging shows no acute infarction. Which mechanism best explains the event?
A) Progressive demyelination of central nervous system axons
B) Temporary cerebral ischemia without permanent tissue infarction
C) Irreversible neuronal necrosis from prolonged arterial occlusion
D) Diffuse cerebral edema caused by meningitis
Correct Answer: Temporary cerebral ischemia without permanent tissue infarction
Rationale: A transient ischemic attack reflects brief focal ischemia with neurologic dysfunction but no established
infarction. Permanent necrosis defines completed ischemic stroke. Demyelination evolves differently and
meningitis causes diffuse inflammatory symptoms rather than a short, fully reversible focal deficit.
3. Review of a head injury shows a lucid interval followed by rapid neurologic deterioration. Which
process is most characteristic of an epidural hematoma?
A) Bleeding into the subarachnoid space from a berry aneurysm
B) Venous bleeding between the dura and arachnoid
C) Arterial bleeding between the skull and dura
D) Diffuse axonal shearing without a focal collection
Correct Answer: Arterial bleeding between the skull and dura
Rationale: Epidural hematoma classically results from arterial bleeding, often involving the middle meningeal
artery, between the inner skull and dura. A lucid interval can precede abrupt decline as the collection expands.
Subdural hematoma is usually venous, while subarachnoid hemorrhage and diffuse axonal injury have different
mechanisms and clinical patterns.
4. An older adult develops gradually progressive gait disturbance, urinary incontinence, and
cognitive decline. Ventricular enlargement is present without marked cortical atrophy. Which
disturbance best explains these findings?
A) Excess dopamine activity in the basal ganglia
B) Autoimmune destruction of peripheral myelin
C) Acute obstruction of the middle cerebral artery
D) Impaired cerebrospinal fluid resorption producing communicating hydrocephalus

Correct Answer: Impaired cerebrospinal fluid resorption producing communicating hydrocephalus
Rationale: The triad of gait impairment, urinary incontinence, and cognitive decline with enlarged ventricles is
characteristic of normal-pressure hydrocephalus, typically caused by impaired CSF resorption. Dopamine excess
does not create ventriculomegaly; arterial occlusion is acute; and peripheral demyelination does not primarily
enlarge cerebral ventricles.
5. A person with Parkinson disease has bradykinesia and resting tremor. Which pathophysiologic
change most directly contributes to these manifestations?
A) Destruction of lower motor neurons in the anterior horn
B) Loss of dopaminergic neurons in the substantia nigra pars compacta
C) Autoimmune blockade of peripheral sodium channels
D) Excess acetylcholine release at the neuromuscular junction
Correct Answer: Loss of dopaminergic neurons in the substantia nigra pars compacta
Rationale: Parkinson disease is driven primarily by degeneration of dopaminergic neurons in the substantia nigra,
reducing dopamine input to basal ganglia circuits that regulate movement. Anterior horn cell loss is associated
with motor neuron disease. Neuromuscular junction and peripheral sodium-channel abnormalities produce
different weakness syndromes.
6. Magnetic resonance imaging shows multifocal plaques in central nervous system white matter
separated in time and location. Which mechanism is most consistent with multiple sclerosis?
A) Accumulation of urate crystals within synovial joints
B) Progressive loss of skeletal-muscle acetylcholine receptors
C) Immune-mediated destruction of central nervous system myelin
D) Degeneration of peripheral Schwann cells only
Correct Answer: Immune-mediated destruction of central nervous system myelin
Rationale: Multiple sclerosis is an immune-mediated demyelinating disease of the central nervous system
involving oligodendrocyte myelin. Lesions disseminated in time and space are characteristic. Peripheral
Schwann-cell disease, neuromuscular-junction receptor loss, and urate deposition represent different disorders.
7. During evaluation of ascending weakness after a gastrointestinal infection, which mechanism is
most consistent with Guillain-Barre syndrome?
A) Ischemic injury limited to the cerebellum
B) Selective loss of neurons in the caudate nucleus
C) Chronic deposition of beta-amyloid plaques in cortex
D) Autoimmune injury to peripheral nerve myelin or axons
Correct Answer: Autoimmune injury to peripheral nerve myelin or axons
Rationale: Guillain-Barre syndrome commonly follows infection and involves immune-mediated injury to
peripheral nerves, producing symmetric ascending weakness and possible autonomic dysfunction. The other
choices describe mechanisms associated with Huntington disease, Alzheimer disease, or focal cerebellar
ischemia.
8. A sudden “worst headache of my life” is followed by neck stiffness and photophobia. Which
pathophysiologic event is most likely?
A) Arterial blood entering the subarachnoid space
B) Slow venous bleeding beneath the dura
C) Obstruction of CSF flow by a benign spinal tumor
D) Chronic demyelination of optic pathways
