1. Which neurotransmitter is primarily targeted by Selective Serotonin Reuptake
Inhibitors (SSRIs)?
A. Serotonin
B. GABA
C. Dopamine
D. Norepinephrine
Correct Answer: A
Expert Explanation: SSRIs work by inhibiting the reuptake of serotonin into the
presynaptic neuron. This increases the availability of serotonin in the synaptic cleft
to improve mood and anxiety. It is the first-line treatment for major depressive
disorder due to its favorable side effect profile.
2. What is the therapeutic serum range for Lithium in the maintenance phase of
Bipolar Disorder?
A. 0.1 - 0.5 mEq/L
B. 2.5 - 3.0 mEq/L
C. 1.5 - 2.0 mEq/L
,D. 0.6 - 1.2 mEq/L
Correct Answer: D
Expert Explanation: The maintenance therapeutic level for Lithium is generally
considered to be 0.6 to 1.2 mEq/L. Levels above 1.5 mEq/L are associated with
toxicity and require immediate intervention. Regular blood monitoring is essential
to ensure safety and efficacy during treatment.
3. Which life-threatening side effect is specifically associated with the use of
Clozapine?
A. Hypertension
B. Hyperactivity
C. Weight loss
D. Agranulocytosis
Correct Answer: D
Expert Explanation: Agranulocytosis is a severe reduction in white blood cell count
that can occur with Clozapine use. Patients must undergo regular Absolute
Neutrophil Count (ANC) monitoring to continue the medication. This protocol is
strictly mandated by the FDA to prevent fatal infections.
, 4. A patient presents with a ‘mask-like’ face, muscle rigidity, and resting tremor.
Which condition does this describe?
A. Pseudoparkinsonism
B. Akathisia
C. Tardive Dyskinesia
D. Dystonia
Correct Answer: A
Expert Explanation: Pseudoparkinsonism is an extrapyramidal side effect caused
by dopamine blockade in the nigrostriatal pathway. It mimics the symptoms of
Parkinson’s disease, including tremors and rigidity. Treatment often involves
reducing the antipsychotic dose or adding an anticholinergic medication.
5. Which medication is considered first-line for the treatment of ADHD in children?
A. Fluoxetine
B. Methylphenidate
C. Lithium
D. Haloperidol
Correct Answer: B
