Section 1: Scientific Foundations and Neurobiology
(Questions 1–35)
Question 1: What is the correct definition of pharmacokinetics?
A. What the drug does to the body—mechanism of action
B. What the body does to the drug—absorption, distribution, metabolism, and excretion
(ADME)
C. The study of drug-receptor interactions
D. The study of drug side effects
Answer: B
Rationale: Pharmacokinetics is the study of how the body processes a medication
through absorption, distribution, metabolism, and excretion (ADME).
Pharmacodynamics, in contrast, is what the drug does to the body—its mechanism of
action. Understanding pharmacokinetics is essential for safe prescribing and monitoring
of psychiatric medications.
,Question 2: Which neurotransmitter is primarily synthesized in the
basal nucleus of Meynert and is crucial for memory and muscle
activation?
A. Dopamine
B. Serotonin
C. Acetylcholine
D. Norepinephrine
Answer: C
Rationale: Acetylcholine is synthesized in the basal nucleus of Meynert and plays a key
role in learning, short-term memory, arousal, and reward. Low levels are associated with
Alzheimer's disease, while high levels can cause Parkinsonian symptoms. This is a critical
neurotransmitter for understanding cognitive disorders.
Question 3: What is the mechanism of action for ketamine in
treating treatment-resistant depression?
A. SSRI receptor blockade
B. NMDA receptor antagonism leading to increased glutamate release
C. Dopamine receptor agonism
D. GABA receptor enhancement
Answer: B
Rationale: Ketamine is a noncompetitive NMDA receptor antagonist. By blocking
NMDA receptors on GABAergic interneurons, it disinhibits glutamate release, which then
triggers synaptogenesis and neuroplasticity, producing rapid antidepressant effects
within hours. This represents a novel mechanism distinct from traditional
antidepressants.
,Question 4: A patient with known CYP2D6 poor metabolizer
status is prescribed an antipsychotic. Which medication would be
most concerning due to increased side-effect risk?
A. Aripiprazole (Abilify)
B. Risperidone (Risperdal)
C. Quetiapine (Seroquel)
D. Olanzapine (Zyprexa)
Answer: B
Rationale: Risperidone is metabolized by CYP2D6. Poor metabolizers have higher
plasma levels, increasing the risk of extrapyramidal symptoms (EPS) and
hyperprolactinemia. This is an important consideration for personalized prescribing in
psychiatric practice.
Question 5: A substance that binds to a receptor and produces a
weaker biological response than a full agonist is known as a:
A. Antagonist
B. Inverse agonist
C. Partial agonist
D. Full agonist
Answer: C
Rationale: A partial agonist activates a receptor but results in a sub-maximal response,
even when all receptors are occupied. It can act as a "middle ground" between an
agonist and an antagonist. This mechanism is important for medications like
aripiprazole, which acts as a partial agonist at dopamine receptors.
Question 6: What labs are indicative of Neuroleptic Malignant
Syndrome (NMS)?
, A. Elevated WBC and elevated CPK
B. Decreased WBC and decreased CPK
C. Elevated TSH and low T4
D. Normal WBC and normal CPK
Answer: A
Rationale: NMS is characterized by elevated WBC (over 11,000) and elevated CPK
(creatine phosphokinase), along with clinical symptoms such as muscle rigidity,
hyperthermia, tachycardia, altered mental status, and autonomic instability. These labs
help differentiate NMS from other conditions.
Question 7: What are the signs and symptoms of Neuroleptic
Malignant Syndrome (NMS)?
A. Hyperreflexia, myoclonus, fever, tachycardia
B. Muscle rigidity, hyperthermia, tachycardia, altered mental status, cherry colored urine
C. Dry mouth, constipation, blurred vision
D. Hypertension, bradycardia, hypothermia
Answer: B
Rationale: NMS is characterized by muscle rigidity, hyperthermia, tachycardia, abnormal
blood pressure, sweating, altered mental status, and cherry colored urine (due to
rhabdomyolysis). This is a life-threatening emergency requiring immediate intervention.
Question 8: What should you do if a patient presents with cherry
colored urine?
A. Check for rhabdomyolysis with CPK
B. Order a urinalysis
C. Start antibiotics
D. Discharge the patient
