PATHOPHYSIOLOGY EXAM QUESTIONS (1–100)
1. In ischemic stroke, the primary mechanism of neuronal injury is:
A. Autoimmune demyelination
B. Excitotoxicity from excessive glutamate release
C. Energy failure leading to ionic imbalance and cell death
D. Viral invasion of neural tissue
Rationale: Ischemic stroke causes ATP depletion, leading to failure of Na⁺/K⁺ pumps, cellular edema,
glutamate excitotoxicity, calcium influx, and eventual necrosis/apoptosis. The ischemic core suffers
irreversible damage within minutes (Chapter 36, 2026).
2. A patient with Alzheimer’s disease exhibits progressive memory loss due to:
A. Demyelination of cortical neurons
B. Accumulation of beta-amyloid plaques and neurofibrillary tangles
C. Autoantibodies against acetylcholine receptors
D. Mitochondrial dysfunction in peripheral nerves
Rationale: Alzheimer’s is characterized by extracellular beta-amyloid plaques and intracellular
hyperphosphorylated tau tangles, leading to synaptic loss, neuronal death, and cortical
atrophy—especially in the hippocampus and association areas (Chapter 36, 2026).
,3. In Parkinson’s disease, the primary pathophysiological change is:
A. Loss of GABAergic neurons in the cerebellum
B. Degeneration of dopaminergic neurons in the substantia nigra pars compacta
C. Autoimmune destruction of motor neurons
D. Excess serotonin in the basal ganglia
Rationale: Parkinson’s involves progressive loss of dopamine-producing neurons in the substantia
nigra, leading to imbalance in the direct/indirect basal ganglia pathways, resulting in bradykinesia,
rigidity, and tremor (Chapter 36, 2026).
4. A complete spinal cord injury at C6 results in:
A. Paraplegia with preserved arm function
B. Tetraplegia with preserved wrist extension but loss of hand function
C. Hemiplegia on the contralateral side
D. Only sensory loss below the injury
Rationale: C6 injury spares the biceps (C5) and wrist extensors (C6) but results in loss of hand
intrinsics (C8–T1). Patients can use adaptive devices for feeding and mobility but have no trunk or
leg control (Chapter 36, 2026).
5. In multiple sclerosis, neurological deficits occur due to:
A. Neuronal apoptosis from protein misfolding
B. Autoimmune-mediated demyelination in the central nervous system
C. Peripheral nerve axonal degeneration
D. Cerebral amyloid angiopathy
Rationale: MS is a T-cell–mediated autoimmune disorder targeting myelin sheaths in the CNS,
causing inflammation, demyelination, and disrupted nerve conduction. Lesions are disseminated in
space and time (Chapter 36, 2026).
6. A patient with myasthenia gravis experiences muscle weakness because:
, A. Motor neurons degenerate
B. Autoantibodies block acetylcholine receptors at the neuromuscular junction
C. Demyelination slows conduction in peripheral nerves
D. Mitochondrial dysfunction impairs muscle energy production
Rationale: Myasthenia gravis is an autoimmune disorder where IgG antibodies target postsynaptic
acetylcholine receptors, reducing end-plate potential and causing fatigable weakness—worse with
activity, better with rest (Chapter 36, 2026).
7. In a generalized tonic-clonic seizure, the postictal state is characterized by:
A. Hyperalertness and euphoria
B. Confusion, drowsiness, and headache due to neuronal exhaustion
C. Immediate return to baseline cognition
D. Persistent motor paralysis
Rationale: The postictal phase results from widespread cortical inhibition and metabolic recovery
after intense neuronal firing. It may last minutes to hours and includes amnesia for the event
(Chapter 36, 2026).
8. Osteoporosis primarily results from:
A. Excessive bone formation by osteoblasts
B. Imbalance between bone resorption and formation, favoring resorption
C. Autoimmune destruction of articular cartilage
D. Defective collagen synthesis
Rationale: Osteoporosis involves increased osteoclast activity and/or decreased osteoblast function,
leading to reduced bone mineral density and microarchitectural deterioration. Postmenopausal
estrogen loss accelerates resorption (Chapter 37, 2026).
9. In osteoarthritis, joint pain and stiffness are primarily caused by:
A. Systemic autoimmune inflammation
