PAT 201 FINAL PAPER 2026 UPDATED ACTUAL
PRACTICE QUESTIONS WITH COMPLETE
SOLUTIONS
◉ what is transmission? Answer: conduction of pain impulses along
the a-delta and c fibers into the dorsal horn of the spinal cord &
eventually to the reticular formation, hypothalamus, thalamus,
limbic
◉ what is perception? Answer: the conscious awareness of pain
◉ what is modulation? Answer: the process of increasing or
decreasing transmission of pain signals throughout the nervous
system
◉ the four phases of pain transmission allow for:
give examples Answer: multiple targets for pharmacological
intervention
NSAIDs act on the peripheral level while opioids act on the CNS
, ◉ what are the three pathways of modulation? Answer: segmental
inhibition
conditioned pain modulation
expectancy-related cortical activation
◉ what is segmental inhibition? Answer: gate control theory
◉ what is gate control theory? Answer: the spinal cord contains a
neurological "gate" that blocks pain signals or allows them to pass
on to the brain
if impulses from a-alpha or a-beta fibers arrive first they can block
pain impulses
◉ T or F: a-delta and a-beta fibers conduct pleasant sensations such
as touch Answer: FALSE: a-beta and a-alpha fibers do
a-delta fibers conduct sharp pain
◉ what is conditioned pain modulation? examples? Answer: pain is
relieved when two noxious stimuli occur at the same time from
different sites
