PSYC 324 MIDTERM EXAM QUESTIONS WITH
ANSWERS AND EXPLANATIONS
| American Public University
1. Which term is best defined as what the body does to a drug through absorption, distribution, metabolism,
and elimination?
A. Additive interaction
B. Distribution
C. Pharmacokinetics
D. Antagonistic interaction
Correct Answer: C. Pharmacokinetics
Explanation: Pharmacokinetics means what the body does to a drug through absorption, distribution, metabolism,
and elimination. The concept should be applied precisely because nearby terms often answer a different clinical or
research question.
2. A person who has used Psilocybin repeatedly stops or sharply reduces use. Which statement about
withdrawal or post-use effects is most accurate?
A. withdrawal often features fatigue, dysphoria, sleep change, and strong craving rather than a classic medically
dangerous autonomic syndrome
B. withdrawal after heavy use can involve fatigue, low mood, sleep change, and craving
C. there is no addiction withdrawal syndrome
D. a classic physical withdrawal syndrome is not typical
Correct Answer: D. a classic physical withdrawal syndrome is not typical
Explanation: The expected pattern is that a classic physical withdrawal syndrome is not typical. Withdrawal
syndromes differ substantially across drug classes, so management should be substance-specific.
3. Which reasoning error would most clearly undermine correct use of Distribution?
A. assuming psychoactive effects stop the instant elimination begins
B. equating presence in blood with equal concentration in every tissue
C. describing receptor binding as if it were elimination
D. treating a high-risk combination as if each drug's effect can be considered independently
Correct Answer: B. equating presence in blood with equal concentration in every tissue
Explanation: The error is equating presence in blood with equal concentration in every tissue. Correct use of
Distribution depends on recognizing that movement of a drug from blood into tissues and body compartments.
4. Which distinction about Overdose education is most accurate?
A. it broadens the focus beyond the drug to employment, recreation, relationships, and other reinforcers
B. it focuses on immediate survival while treatment focuses on the longer-term disorder
C. the immediate goal is reducing injection-related harm, not requiring abstinence before receiving help
D. the therapy is professionally delivered whereas mutual-support meetings themselves are peer-based
Correct Answer: B. it focuses on immediate survival while treatment focuses on the longer-term disorder
Explanation: The important distinction is that it focuses on immediate survival while treatment focuses on the
longer-term disorder. Understanding how treatments differ prevents false either-or choices and mechanism errors.
,5. A person who has used Synthetic cathinones repeatedly stops or sharply reduces use. Which statement about
withdrawal or post-use effects is most accurate?
A. dependence can produce a severe withdrawal syndrome with anxiety, tremor, delirium, and autonomic
instability
B. after heavy use some people experience fatigue, low mood, sleep disturbance, or concentration problems
C. a severe classic withdrawal syndrome is not usually the central risk, but craving and problematic use can
occur
D. withdrawal can involve fatigue, depression, sleep disturbance, and craving after heavy use
Correct Answer: D. withdrawal can involve fatigue, depression, sleep disturbance, and craving after heavy use
Explanation: The expected pattern is that withdrawal can involve fatigue, depression, sleep disturbance, and
craving after heavy use. Withdrawal syndromes differ substantially across drug classes, so management should be
substance-specific.
6. Which statement best captures an important distinction involving Dopamine and reinforcement?
A. reward circuitry is broader than a single pleasure center or one neurotransmitter
B. it avoids reducing addiction to either biology or personal choice alone
C. dopamine is not simply a chemical for pleasure and does not by itself explain addiction
D. cognitive factors interact with reinforcement and biology rather than replacing them
Correct Answer: C. dopamine is not simply a chemical for pleasure and does not by itself explain addiction
Explanation: The key distinction is that dopamine is not simply a chemical for pleasure and does not by itself
explain addiction. Keeping related concepts separate improves interpretation of substance-use behavior and
evidence.
7. Consider this situation: using half-life to estimate how long drug concentrations decline. Which concept is
most directly illustrated?
A. Elimination
B. Blood-brain barrier
C. Cross-tolerance
D. Route of administration
Correct Answer: A. Elimination
Explanation: This is an example of Elimination because it involves removal of a drug and its metabolites from the
body, commonly through urine, bile, breath, or other routes. The scenario shows how the term functions in real
decisions rather than only as a definition.
8. Which term is best defined as a substance-specific syndrome that develops after reduction or cessation
following repeated exposure that produced neuroadaptation?
A. Substance use disorder
B. Co-occurring disorder
C. Diagnosis
D. Withdrawal
Correct Answer: D. Withdrawal
Explanation: Withdrawal means a substance-specific syndrome that develops after reduction or cessation
following repeated exposure that produced neuroadaptation. The concept should be applied precisely because
nearby terms often answer a different clinical or research question.
,9. A care team is comparing several evidence-based options and specifically considers Cognitive-behavioral
therapy. Which choice best demonstrates treatment-to-problem matching?
A. Match Cognitive-behavioral therapy to the target situation: relapse prevention and treatment across many
substance use disorders
B. Choose Methadone for OUD without checking whether it addresses the same treatment target
C. Choose Acamprosate without checking whether it addresses the same treatment target
D. Choose Naltrexone for AUD without checking whether it addresses the same treatment target
Correct Answer: A. Match Cognitive-behavioral therapy to the target situation: relapse prevention and
treatment across many substance use disorders
Explanation: Appropriate matching means using Cognitive-behavioral therapy when relapse prevention and
treatment across many substance use disorders. Evidence-based status alone does not make every intervention
suitable for every substance or clinical goal.
10. Which implication follows most logically from the concept of Biopsychosocial model?
A. contingency management deliberately uses operant principles to reinforce recovery behaviors
B. multilevel assessment supports individualized prevention and treatment
C. medical framing can reduce stigma and support treatment access when combined with broader psychosocial
understanding
D. withdrawal relief can maintain drug use even when euphoria has diminished
Correct Answer: B. multilevel assessment supports individualized prevention and treatment
Explanation: The strongest implication is that multilevel assessment supports individualized prevention and
treatment. This follows directly from the meaning of Biopsychosocial model and avoids overgeneralizing beyond
the evidence.
11. Which concept is best described as a study design that assigns participants by chance to conditions to
reduce systematic baseline differences?
A. Public-health surveillance
B. Randomized controlled trial
C. Treatment access
D. Prescription drug monitoring program
Correct Answer: B. Randomized controlled trial
Explanation: Randomized controlled trial is a study design that assigns participants by chance to conditions to
reduce systematic baseline differences. The definition identifies the specific public-health or research function
being tested.
, 12. A person with suspected Buprenorphine exposure has an uncertain dose and incomplete history. Which
initial reasoning approach is safest?
A. Wait for the person to become fully alert before checking vital signs or immediate safety
B. Base the response only on whether Buprenorphine is legal or illegal rather than on physiologic risk
C. First assess airway, breathing, circulation, level of consciousness, co-ingestants, and the specific danger
associated with Buprenorphine before assuming the presentation is uncomplicated
D. Assume Buprenorphine alone explains every symptom and skip evaluation for co-use or medical
complications
Correct Answer: C. First assess airway, breathing, circulation, level of consciousness, co-ingestants, and the
specific danger associated with Buprenorphine before assuming the presentation is uncomplicated
Explanation: Unknown-dose substance presentations require stabilization and broad assessment before a narrow
conclusion. The specific danger for Buprenorphine includes starting it too soon after a full opioid agonist can
precipitate withdrawal because of its high receptor affinity.
13. Which term is best defined as brief systematic identification of people who may have risky use or a
possible disorder and need fuller assessment?
A. Co-occurring disorder
B. Diagnosis
C. Screening
D. Drug misuse
Correct Answer: C. Screening
Explanation: Screening means brief systematic identification of people who may have risky use or a possible
disorder and need fuller assessment. The concept should be applied precisely because nearby terms often answer a
different clinical or research question.
14. Which reasoning error would most clearly undermine correct use of Licit versus illicit status?
A. concluding that a legal drug is automatically less harmful than every illegal drug
B. using an intensive residential program as the default response to any positive screen
C. describing dopamine as the sole cause of all substance use disorders
D. assuming all routes deliver the same dose to the brain at the same speed
Correct Answer: A. concluding that a legal drug is automatically less harmful than every illegal drug
Explanation: The error is concluding that a legal drug is automatically less harmful than every illegal drug. Correct
use of Licit versus illicit status depends on recognizing that a legal classification describing whether possession or
use is permitted under specific laws and circumstances.
