Which of the following ADHD medications is not a stimulant?
Adderall
Strattera
Vyvanse
Ritalin
The Correct Answer is B
A. Adderall (amphetamine/dextroamphetamine) is a stimulant that increases dopamine and norepinephrine levels in the brain, improving focus and impulse control in individuals with ADHD. It is a Schedule II controlled substance due to its potential for abuse and dependence.
B. Strattera (atomoxetine) is a non-stimulant medication used for ADHD. It is a selective norepinephrine reuptake inhibitor (NRI) that helps with attention and impulse control but has a lower risk of abuse compared to stimulant medications. Unlike stimulants, it may take several weeks to show full effects.
C. Vyvanse (lisdexamfetamine) is a stimulant that is a prodrug of dextroamphetamine, meaning it must be metabolized in the body before becoming active. This mechanism provides a longer, smoother effect with a lower potential for abuse compared to immediate-release stimulants.
D. Ritalin (methylphenidate) is a stimulant that increases dopamine and norepinephrine activity in the brain, improving focus and impulse control. It is commonly used in both children and adults with ADHD and has short-acting, intermediate, and long-acting formulations.

Correct Answer is C
Explanation
A. Depressed type. Schizoaffective disorder, depressive type, involves schizophrenia symptoms (delusions, hallucinations, disorganized thinking) along with major depressive episodes. There is no history of mania or hypomania, distinguishing it from the bipolar type.
B. Unspecified type. Schizoaffective disorder, unspecified type, is used when the clinician determines that the patient meets criteria for schizoaffective disorder but does not clearly fit into the bipolar or depressive subtypes.
C. Anxiety type. There is no "anxiety type" of schizoaffective disorder. While individuals with schizoaffective disorder may experience anxiety, it is not a defining feature. Anxiety disorders are separate conditions and do not define a subtype of schizoaffective disorder.
D. Bipolar type. Schizoaffective disorder, bipolar type, is diagnosed when schizophrenia symptoms occur alongside manic or mixed episodes, with or without depressive episodes. This distinguishes it from the depressive type, which lacks manic symptoms.
Correct Answer is A
Explanation
A. Haloperidol (Haldol) is a first-generation (typical) antipsychotic that primarily blocks dopamine (D2) receptors. It is associated with a higher risk of extrapyramidal side effects (EPS), including dystonia, akathisia, and tardive dyskinesia, compared to second-generation antipsychotics.
B. Ziprasidone (Geodon) is a second-generation (atypical) antipsychotic that blocks both dopamine (D2) and serotonin (5-HT2A) receptors. It has a lower risk of EPS but can cause QT prolongation, requiring ECG monitoring in patients with cardiac conditions.
C. Risperidone (Risperdal) is a second-generation antipsychotic with dopamine and serotonin antagonism. It is effective for schizophrenia, bipolar disorder, and irritability in autism but has a higher likelihood of prolactin elevation and EPS at higher doses.
D. Olanzapine (Zyprexa) is a second-generation antipsychotic known for its high risk of metabolic side effects, including weight gain, diabetes, and dyslipidemia. It has a lower risk of EPS compared to first-generation antipsychotics.
