In substance use disorder, dopamine is released within the reward center of the brain. Where is this located?
The ventral tegmental area and the nucleus accumbens
The mesocortical pathway
The locus coeruleus
The raphe nucleus
The Correct Answer is A
Choice A reason: The ventral tegmental area (VTA) and nucleus accumbens are central components of the mesolimbic dopamine pathway, which is the primary reward circuit in the brain. Dopamine release in this pathway reinforces behaviors and is heavily involved in addiction and substance use disorders.
Choice B reason: The mesocortical pathway connects the VTA to the prefrontal cortex and is involved in cognition, emotion, and executive function. While it plays a role in psychiatric conditions, it is not the primary reward center.
Choice C reason: The locus coeruleus is involved in arousal and stress responses via norepinephrine, not dopamine. It is not part of the reward system central to substance use disorders.
Choice D reason: The raphe nucleus is the primary source of serotonin in the brain and is involved in mood regulation. It does not mediate dopamine-driven reward processes.

Correct Answer is C
Explanation
Choice A reason: Cannabis dependence was a term used in earlier diagnostic frameworks such as DSM-IV. It has since been replaced by the broader and more clinically accurate term “cannabis use disorder” in DSM-5, which encompasses both abuse and dependence.
Choice B reason: Cannabis abuse disorder is also an outdated term from DSM-IV. DSM-5 integrates abuse and dependence into a single diagnosis—cannabis use disorder—based on severity and symptom criteria.
Choice C reason: Cannabis use disorder is the correct DSM-5 diagnosis. It includes patterns of problematic use leading to significant impairment or distress, such as continued use despite interpersonal problems, legal issues, and risky behaviors like driving under the influence. The patient’s daily use, denial of the problem, and conflict with his spouse meet criteria for this diagnosis.
Choice D reason: Unspecified cannabis-related disorder is used when symptoms are present but do not meet full criteria for a specific diagnosis. In this case, the patient clearly meets criteria for cannabis use disorder, making this option inappropriate.
Correct Answer is B
Explanation
Choice A reason: Rational emotive behavioral therapy (REBT) focuses on challenging irrational beliefs and promoting rational thinking. While helpful for emotional regulation, it is not the primary evidence-based approach for relapse prevention in substance use.
Choice B reason: Cognitive behavioral therapy (CBT) is the most widely supported therapy for relapse prevention. It helps clients identify triggers, develop coping strategies, and restructure maladaptive thoughts that contribute to substance use. CBT is effective in maintaining sobriety and preventing relapse.
Choice C reason: Dialectical behavioral therapy (DBT) is beneficial for emotional regulation and is often used for borderline personality disorder. While it may help with co-occurring conditions, CBT is more targeted for relapse prevention.
Choice D reason: Solution-focused therapy emphasizes strengths and future goals but lacks the structured approach needed for relapse prevention. It is better suited for short-term problem-solving than long-term substance use management.
