Instructions
● This quiz bank consists of 70 multiple-choice questions, each worth 1 point.
● Questions are grouped by topics: Neuro, Cardio, Endocrine, and Infection
Pharmacology (15 questions each), Dosage Calculations (10 questions), and
Mechanism and Therapeutic Logic (10 questions).
● Select the best answer (A–D) for each question.
● Correct answers are indicated in blue with faculty-approved rationales
referencing pharmacologic standards (e.g., Goodman & Gilman’s The
Pharmacological Basis of Therapeutics, FDA guidelines, or clinical
protocols like AHA, ADA, or IDSA).
,Neuro Pharmacology (15 Questions)
1. Which medication is the first-line treatment for generalized anxiety
disorder?
A. Alprazolam
B. Buspirone
C. Diazepam
D. Lorazepam
Correct Answer: B. Buspirone
Rationale: Buspirone, a partial agonist at serotonin 5-HT1A receptors,
provides anxiolytic effects without the sedation or dependence risk of
benzodiazepines (e.g., alprazolam, diazepam, lorazepam). It is recommended
as first-line for chronic anxiety per American Psychiatric Association (APA)
guidelines due to its favorable safety profile.
2. What is the primary mechanism of action for selective serotonin
reuptake inhibitors (SSRIs) in treating depression?
A. Blockade of dopamine reuptake
B. Inhibition of serotonin reuptake
C. Antagonism of adrenergic receptors
D. Enhancement of GABA activity
Correct Answer: B. Inhibition of serotonin reuptake
Rationale: SSRIs (e.g., fluoxetine) selectively block the serotonin
transporter, increasing synaptic serotonin levels to enhance mood regulation.
This mechanism is well-documented in Goodman & Gilman’s and supported
by APA guidelines for depression management.
3. Which anticonvulsant is commonly used for neuropathic pain
management?
A. Phenytoin
B. Gabapentin
C. Carbamazepine
D. Valproic acid
Correct Answer: B. Gabapentin
Rationale: Gabapentin binds to the alpha-2-delta subunit of voltage-gated
, calcium channels, reducing excitatory neurotransmitter release and
alleviating neuropathic pain. It is a first-line agent per American Academy
of Neurology (AAN) guidelines for conditions like diabetic neuropathy.
4. What is a key adverse effect of tricyclic antidepressants (TCAs)?
A. Weight loss
B. Orthostatic hypotension
C. Hyperglycemia
D. Tachycardia
Correct Answer: B. Orthostatic hypotension
Rationale: TCAs (e.g., amitriptyline) block alpha-1 adrenergic receptors,
causing vasodilation and orthostatic hypotension. This anticholinergic effect
is noted in pharmacology texts and requires patient monitoring.
5. Which medication is used for acute migraine treatment via 5-HT1B/1D
receptor agonism?
A. Propranolol
B. Sumatriptan
C. Topiramate
D. Verapamil
Correct Answer: B. Sumatriptan
Rationale: Sumatriptan, a triptan, activates serotonin 5-HT1B/1D receptors,
causing cranial vasoconstriction and inhibiting pain pathway inflammation.
It is a first-line acute migraine treatment per American Headache Society
(AHS) guidelines.
6. What is the primary mechanism of levodopa in Parkinson’s disease?
A. Dopamine receptor antagonism
B. Conversion to dopamine in the brain
C. Inhibition of COMT
D. MAO-B inhibition
Correct Answer: B. Conversion to dopamine in the brain
Rationale: Levodopa crosses the blood-brain barrier and is converted to
dopamine by dopa decarboxylase, replenishing dopamine in the basal
ganglia. It is combined with carbidopa to prevent peripheral metabolism, per
