,Q1. In a client with alcohol use disorder and comorbid major depressive disorder,
which neurobiological mechanism most directly explains the high relapse rate during
early abstinence when the client is not yet on antidepressant medication?
A. Kindling-induced sensitization of the amygdala leading to heightened stress
response
B. Upregulation of dopamine D2 receptors in the mesolimbic pathway
C. Overactivation of the hypothalamic-pituitary-adrenal (HPA) axis due to allostatic
load
D. Increased glutamatergic transmission in the prefrontal cortex during withdrawal
Correct Answer: C. Overactivation of the hypothalamic-pituitary-adrenal (HPA) axis
due to allostatic load
Rationale: Chronic alcohol use disrupts the HPA axis, and during early abstinence, an
overactive stress response increases craving and relapse risk, especially with comorbid
depression. Kindling and glutamate changes are relevant but less directly tie to comorbid
depression and early relapse.
Why Wrong:
A - Kindling is more associated with seizure susceptibility and withdrawal
progression, not primarily stress-driven relapse.
B - Chronic alcohol use typically downregulates, not upregulates, D2 receptors.
D - Glutamatergic changes contribute to withdrawal but are not the principal
mechanism linking depression and relapse.

Q2. A client on buprenorphine/naloxone for opioid use disorder reports precipitated
withdrawal after taking their dose. Which scenario most plausibly explains this
adverse event?
A. The client took the medication sublingually after using heroin 12 hours prior.
B. The client administered the medication intravenously to accelerate absorption.
C. The client started buprenorphine too soon after their last full opioid agonist dose.
D. The client took the medication with a CYP3A4 inhibitor, increasing buprenorphine
levels.
Correct Answer: C. The client started buprenorphine too soon after their last full
opioid agonist dose.
Rationale: Precipitated withdrawal occurs when buprenorphine, a partial agonist with
high receptor affinity, displaces a full agonist like heroin or methadone from mu receptors.
Starting buprenorphine too soon after the last full agonist dose-before significant
withdrawal has begun-is the classic cause.

, Why Wrong:
A - Waiting 12 hours after heroin is generally sufficient to avoid precipitated
withdrawal.
B - IV misuse of buprenorphine/naloxone does not cause precipitated withdrawal; it
may cause other risks.
D - CYP3A4 inhibitors increase buprenorphine levels but do not cause precipitated
withdrawal.

Q3. Which ethical principle is most directly challenged when a counselor accepts a
gift from a client's family member after termination of treatment?
A. Beneficence
B. Nonmaleficence
C. Fidelity
D. Justice
Correct Answer: C. Fidelity
Rationale: Fidelity involves maintaining trust and honoring commitments. Accepting gifts
post-termination can create conflicts of interest and undermine the integrity of the
professional relationship, even after formal treatment ends, as it may exploit the former
client's vulnerability.
Why Wrong:
A - Beneficence focuses on promoting good, not directly on gift acceptance.
B - Nonmaleficence is about avoiding harm, but the primary issue is a breach of trust.
D - Justice concerns fairness and equity, not gift boundaries.

Q4. A client with a history of opioid use disorder is seeking treatment. They are
currently taking naltrexone but report persistent cravings. Which adjustment is most
evidence-based?
A. Switch to buprenorphine/naloxone
B. Add behavioral therapy such as CBT
C. Increase naltrexone dose above recommended
D. Add a benzodiazepine for anxiety
Correct Answer: B. Add behavioral therapy such as CBT
Rationale: Persistent cravings despite naltrexone indicate that medication alone is
insufficient. Adding behavioral therapy (e.g., CBT) is evidence-based to address
conditioned cues and coping skills. Switching to buprenorphine may help some, but it is
not the first-line adjustment if naltrexone is otherwise effective.
