Correct Answer: C

Rationale: The correct answer is C, haloperidol (Haldol), because it is a first-generation antipsychotic, not a third-generation one. Haloperidol primarily acts on dopamine receptors, unlike third-generation antipsychotics which target multiple neurotransmitter systems. Lurasidone, cariprazine, and aripiprazole are all third-generation antipsychotics with unique pharmacological profiles targeting serotonin and dopamine receptors.
Therefore, haloperidol does not fit the criteria for a third-generation antipsychotic.

Choices A, B, and D are incorrect because they are indeed third-generation antipsychotics with distinct mechanisms of action.

Correct Answer: A

Rationale: The correct answer is A: Dopamine. In
Tourette's, there is evidence of dysregulation in the dopamine system, leading to motor and vocal tics. Dopamine plays a key role in motor control and is implicated in the pathophysiology of
Tourette's. Serotonin, glutamate, and GABA abnormalities are also observed in
Tourette's, but dopamine abnormalities are most strongly associated. Serotonin abnormalities are more linked to OCD and mood disorders often comorbid with
Tourette's. Glutamate and GABA abnormalities are involved in other neurological conditions but not the primary neurotransmitter dysfunction in
Tourette's.

Correct Answer: C

Rationale: Desmopressin is effective for enuresis because it helps reduce urine production at night. It acts by increasing water reabsorption in the kidneys, leading to decreased urine output during sleep. Gabapentin, laxatives, and SSRIs are not indicated for enuresis treatment. Gabapentin is primarily used for neuropathic pain and seizures, laxatives for constipation, and SSRIs for depression and anxiety.
Therefore, Desmopressin is the correct choice as it directly targets the underlying cause of enuresis.

Correct Answer: A

Rationale: The correct answer is A: Sudden onset of psychotic symptoms in less than a month. Brief psychotic disorder, as defined by DSM-5, involves the sudden onset of psychotic symptoms such as hallucinations, delusions, disorganized speech or behavior, lasting for at least one day but less than one month. This time frame distinguishes it from other psychotic disorders like schizophrenia.

Choices B, C, and D are incorrect because they exceed the specified duration of symptoms for brief psychotic disorder. It is crucial to adhere to the specific timeframe outlined in the diagnostic criteria to accurately identify and differentiate this disorder from others.

Correct Answer: A

Rationale: The correct answer is A: Vindictive. Conduct disorder is characterized by persistent patterns of behavior that violate the rights of others. Vindictiveness is not a common symptom of conduct disorder. Aggressive behavior towards people and animals, deceitfulness, and destroying property are classic symptoms. Vindictiveness implies a desire for revenge, which is not typically associated with conduct disorder.
Therefore, A is the correct answer as it does not align with the common symptoms of conduct disorder.
