NR546 Advanced Psychopharmacology: 100 Final Exam Practice
Questions & Rationales
1. Which of the following is considered the pleasure center of the
brain?
• A) Cortico-striatal-thalamic-cortical loop
• B) Mesolimbic dopamine pathway
• C) Mesocortical dopamine pathway
• D) Nigrostriatal pathway
• Correct ,,answer,,: B) Mesolimbic dopamine pathway
• Rationale: The mesolimbic pathway, which projects from the ventral
tegmental area (VTA) to the nucleus accumbens, is the core of the
brain's reward circuitry. It is activated by natural rewards and is
hijacked by addictive substances.
2. A 35-year-old cigarette smoker would like to quit but is nervous
because she typically craves a cigarette approximately every 2 hours.
The craving and withdrawal are due to:
• A) Desensitization of nicotinic receptors
, • B) Resensitization of nicotinic receptors
• C) Desensitization of muscarinic receptors
• D) Resensitization of muscarinic receptors
• Correct ,,answer,,: B) Resensitization of nicotinic receptors
• Rationale: Chronic smoking desensitizes nicotinic receptors. When a
person stops smoking, these receptors rapidly "resensitize," leading
to intense cravings and withdrawal symptoms as the brain struggles
to adapt to the absence of nicotine.
3. The reactive reward system signals the immediate prospect of
pleasure or pain and triggers drug-seeking behavior.
• A) True
• B) False
• Correct ,,answer,,: A) True
• Rationale: The reactive reward system, which involves the amygdala
and nucleus accumbens, is responsible for the immediate, impulsive
response to drug-related cues, driving craving and seeking behavior.
4. What role does the amygdala play in substance abuse?
• A) Releases phasic bursts of dopamine to the nucleus accumbens
when drugs of abuse are present
• B) Communicates to the ventral tegmental area when cues related to
drugs of abuse are present
• C) Forms synapses with neurons of the prefrontal cortex during the
development of addiction
• D) All of the above
• Correct ,,answer,,: B) Communicates to the ventral tegmental
area when cues related to drugs of abuse are present
• Rationale: The amygdala is a key structure in the brain's stress and
fear circuitry. It learns to associate environmental cues (people,
, places, things) with the drug's effects, and when those cues are
encountered, it triggers a conditioned response that can lead to
craving and relapse.
5. A 45-year-old patient has tried unsuccessfully to quit smoking
several times over the past ten years. Nicotine's actions at which
receptors are considered primarily responsible for its reinforcing
effects?
• A) Dopamine D1 receptors
• B) Nicotinic receptors
• C) Acetylcholine receptors
• D) Opioid receptors
• Correct ,,answer,,: B) Nicotinic receptors
• Rationale: Nicotine's reinforcing effects are primarily mediated by its
action on nicotinic acetylcholine receptors (nAChRs) in the brain,
particularly in the VTA and nucleus accumbens. Activation of these
receptors leads to dopamine release.
6. Patrick is a 22-year-old male who recently experienced a psychotic-
like episode after trying MDMA ("ecstasy") while at a party. A key
binding site for hallucinogens is the:
• A) GABA-A receptor
• B) Cannabinoid 1 receptor
• C) Serotonin 2A receptor
• D) Serotonin 2C receptor
• Correct ,,answer,,: C) Serotonin 2A receptor
• Rationale: Activation of the serotonin 5HT2A receptor is the primary
mechanism by which classical hallucinogens, including LSD,
psilocybin, and MDMA, produce their profound perceptual and
cognitive effects.
, 7. Cocaine's actions at the dopamine transporter (DAT) are most
similar to which medication?
• A) Amphetamine
• B) Methylphenidate
• C) Nicotine
• D) Caffeine
• Correct ,,answer,,: B) Methylphenidate
• Rationale: Both cocaine and methylphenidate block the dopamine
transporter (DAT), leading to increased extracellular dopamine levels.
This mechanism is responsible for their reinforcing effects and is why
methylphenidate has abuse potential.
8. A patient with alcohol use disorder is prescribed disulfiram. The
patient should be cautioned that an alcohol reaction may occur if they
ingest alcohol within:
• A) 24 hours
• B) 7 days
• C) 14 days
• D) 30 days
• Correct ,,answer,,: C) 14 days
• Rationale: Disulfiram irreversibly inhibits aldehyde dehydrogenase.
The body must synthesize new enzyme, a process that can take 1-2
weeks. Therefore, patients must avoid all alcohol-containing products
for up to 14 days after their last dose to prevent a reaction.
9. Methadone is used in the treatment of opioid use disorder. Its
mechanism of action is best described as a:
• A) Partial mu-opioid receptor agonist
• B) Full mu-opioid receptor agonist with a long half-life
• C) Mu-opioid receptor antagonist
