BATCH 1 — QUESTIONS 1–50
1.
A 48-year-old male presents with chronic axial low back pain. MRI demonstrates Modic type I
changes at L4–L5. These findings most likely represent:
A. Fatty marrow replacement
B. Subchondral sclerosis
C. Active inflammatory endplate changes
D. Disc calcification
Answer: C
Rationale:
Modic type I changes represent bone marrow edema and inflammatory changes at vertebral
endplates. They are associated with active low back pain. Type II indicates fatty replacement,
and Type III indicates sclerosis.

2.
The primary mechanism of action of gabapentin in neuropathic pain involves:
A. Voltage-gated sodium channel blockade
B. Inhibition of serotonin reuptake
C. Binding to α2δ subunit of voltage-gated calcium channels
D. Direct NMDA receptor antagonism
Answer: C
Rationale:
Gabapentin binds to the α2δ subunit of presynaptic voltage-gated calcium channels, decreasing
excitatory neurotransmitter release (glutamate, substance P), reducing central sensitization.
3.
A patient undergoing a lumbar transforaminal epidural steroid injection develops sudden
paraplegia. The most likely mechanism is:
A. Epidural hematoma
B. Intrathecal injection of steroid
