PSYCHOPHARMACOLOGY PRINCIPLES, PHARMACOKINETICS & NEUROBIOLOGY (Q1–
Q10)
Q1. A PMHNP prescribes sertraline to a patient with major depressive disorder. The
patient asks why therapeutic effects take several weeks despite immediate serotonin
reuptake inhibition. What is the best explanation?
A. Serotonin receptors require permanent structural changes
B. Gene expression and receptor downregulation take time
C. The drug must accumulate in the liver first
D. Serotonin is not active in the central nervous system
,Correct Answer: 🔴 B. Gene expression and receptor downregulation take time
Explanation: 🔹 SSRIs increase synaptic serotonin immediately, but clinical improvement
depends on downstream neuroadaptive changes such as receptor downregulation,
neuroplasticity, and gene expression changes. Option A is incorrect because structural
receptor changes are not permanent. Option C is incorrect since hepatic accumulation is
not required for antidepressant effect. Option D is false because serotonin is a key CNS
neurotransmitter involved in mood regulation.
Q2. Which pharmacokinetic factor most significantly affects drug distribution in elderly
patients?
A. Increased gastric emptying
B. Decreased body fat
C. Increased plasma albumin
D. Decreased total body water
Correct Answer: 🔴 D. Decreased total body water
Explanation: 🔹 Older adults have reduced total body water, increasing serum
concentrations of water-soluble drugs and altering distribution. Option A is incorrect
because gastric emptying is typically delayed, not increased. Option B is incorrect as
body fat generally increases with age. Option C is incorrect because albumin often
decreases, not increases.
Q3. A patient taking fluoxetine develops tremors, hyperreflexia, and diaphoresis after
starting linezolid. What is the most likely condition?
A. Neuroleptic malignant syndrome
B. Serotonin syndrome
C. Anticholinergic toxicity
D. Lithium toxicity
Correct Answer: 🔴 B. Serotonin syndrome
,Explanation: 🔹 Fluoxetine combined with linezolid (a MAOI) increases serotonin activity,
causing serotonin syndrome characterized by neuromuscular hyperactivity and
autonomic instability. NMS (Option A) is associated with dopamine blockade.
Anticholinergic toxicity (Option C) presents with dry skin and mydriasis. Lithium toxicity
(Option D) causes tremor but not hyperreflexia with autonomic hyperactivity.
Q4. Which receptor is primarily targeted by second-generation antipsychotics to
reduce positive symptoms of schizophrenia?
A. Dopamine D2 receptors
B. Serotonin 5-HT2A receptors
C. GABA-A receptors
D. NMDA receptors
Correct Answer: 🔴 B. Serotonin 5-HT2A receptors
Explanation: 🔹 Atypical antipsychotics primarily antagonize 5-HT2A receptors,
indirectly modulating dopamine pathways to reduce psychosis and side effects. D2
blockade (Option A) contributes but is less dominant. GABA-A (C) relates to
anxiety/sedation. NMDA (D) is associated with glutamate modulation.
Q5. A patient is prescribed lithium. Which lab value must be monitored regularly?
A. Troponin
B. Serum creatinine
C. Amylase
D. D-dimer
Correct Answer: 🔴 B. Serum creatinine
Explanation: 🔹 Lithium is renally excreted, making kidney function (creatinine, GFR)
essential for monitoring toxicity risk. Troponin (A) is cardiac-specific. Amylase (C) relates
to pancreatic function. D-dimer (D) evaluates clotting disorders.
, Q6. Which antidepressant class is most associated with hypertensive crisis when
combined with tyramine-rich foods?
A. SSRIs
B. MAOIs
C. SNRIs
D. TCAs
Correct Answer: 🔴 B. MAOIs
Explanation: 🔹 MAOIs inhibit monoamine oxidase, preventing breakdown of tyramine,
leading to excessive norepinephrine release and hypertensive crisis. SSRIs (A), SNRIs (C),
and TCAs (D) do not have this dietary restriction.
Q7. A patient on haloperidol develops rigidity, fever, and autonomic instability. What is
the priority intervention?
A. Administer naloxone
B. Start bromocriptine
C. Give flumazenil
D. Administer propranolol
Correct Answer: 🔴 B. Start bromocriptine
Explanation: 🔹 These symptoms indicate neuroleptic malignant syndrome;
bromocriptine, a dopamine agonist, is used to reverse dopamine blockade. Naloxone (A)
reverses opioids. Flumazenil (C) reverses benzodiazepines. Propranolol (D) treats
akathisia.
Q8. Which neurotransmitter is primarily implicated in anxiety disorders?
A. Dopamine
B. Serotonin
C. GABA
D. Acetylcholine
Correct Answer: 🔴 C. GABA
