Questions 1–10: Neurobiology and Principles of
Psychopharmacology
Q1.
A 35-year-old patient with major depressive disorder reports minimal improvement
after 6 weeks of treatment with a therapeutic dose of an SSRI. Which pharmacologic
principle best explains why clinicians generally wait several weeks before determining
whether an antidepressant is effective?
A. Serotonin receptors immediately become desensitized after the first dose.
B. Adaptive changes in receptor sensitivity and downstream neuronal signaling
require time.
C. Plasma drug concentrations do not reach steady state for approximately six weeks.
D. Antidepressants require complete hepatic enzyme induction before clinical benefit
occurs.
Correct Answer: 🔴 B. Adaptive changes in receptor sensitivity and downstream
neuronal signaling require time.
Explanation: Although serotonin reuptake inhibition occurs within hours, symptom
improvement depends on gradual neuroadaptive changes including receptor
regulation, altered intracellular signaling, and neuroplasticity. Steady state usually
occurs within days—not weeks—making options C and D incorrect. Option A
oversimplifies receptor physiology.
,Q2.
A PMHNP is selecting an antidepressant for an older adult with significant
anticholinergic sensitivity. Which medication would generally be the least desirable
initial choice?
A. Sertraline
B. Escitalopram
C. Amitriptyline
D. Duloxetine
Correct Answer: 🔴 C. Amitriptyline
Explanation: Amitriptyline is a tricyclic antidepressant with substantial anticholinergic
effects, increasing the risk of delirium, constipation, urinary retention, blurred vision,
and falls in older adults. SSRIs are generally preferred because of a more favorable
safety profile.
Q3.
A patient taking fluoxetine develops agitation, tremor, diaphoresis, hyperreflexia, and
clonus after beginning linezolid. Which diagnosis is most likely?
A. Neuroleptic malignant syndrome
B. Malignant hyperthermia
C. Serotonin syndrome
D. Acute dystonia
Correct Answer: 🔴 C. Serotonin syndrome
Explanation: Linezolid possesses monoamine oxidase-inhibiting properties. When
combined with serotonergic medications such as fluoxetine, excessive serotonin activity
, may develop, producing autonomic instability, neuromuscular hyperactivity, and
altered mental status. The remaining options have different clinical presentations.
Q4.
Which pharmacokinetic concept is most directly affected by impaired hepatic
metabolism?
A. Drug absorption
B. Bioavailability after intravenous administration
C. Drug clearance
D. Protein binding
Correct Answer: 🔴 C. Drug clearance
Explanation: The liver plays a central role in metabolizing many psychotropic
medications. Reduced hepatic function decreases clearance, potentially increasing
serum drug concentrations and toxicity. Absorption and protein binding are affected
less directly.
Q5.
A patient stabilized on lithium develops vomiting and dehydration from viral
gastroenteritis. What is the PMHNP's greatest immediate concern?
A. Reduced therapeutic effectiveness
B. Lithium toxicity
C. Serotonin syndrome
D. Neuroleptic malignant syndrome
Correct Answer: 🔴 B. Lithium toxicity
