D027 NURS 5204 Advanced
Pathopharmacological Foundations (NLM)
Objective Assessment Review (Qns & Ans)
2025
1. What is the primary mechanism of action of beta-blockers in
cardiovascular conditions?
a. Vasodilation through nitric oxide release
b. Inhibition of angiotensin-converting enzyme
c. Blockade of beta-adrenergic receptors ( Correct ANS )
d. Stimulation of alpha-adrenergic receptors
Rationale: Beta-blockers block beta-adrenergic receptors,
decreasing heart rate and cardiac workload.
2. Which pathophysiological change is most associated with
Type 1 diabetes mellitus?
©2025
, a. Peripheral insulin resistance
b. Autoimmune destruction of pancreatic beta cells ( Correct
ANS )
c. Overproduction of insulin
d. Dysfunction of alpha cells in the pancreas
Rationale: Type 1 diabetes results from the autoimmune
destruction of insulin-producing beta cells.
3. Which pharmacokinetic process is primarily affected in
patients with impaired liver function?
a. Absorption
b. Distribution
c. Metabolism ( Correct ANS )
d. Excretion
Rationale: The liver is the primary site of drug metabolism;
liver impairment can lead to drug accumulation.
4. What is the role of angiotensin II in the pathophysiology of
hypertension?
a. Promoting sodium excretion
b. Causing vasodilation
©2025
, c. Inducing vasoconstriction and aldosterone release ( Correct
ANS )
d. Decreasing cardiac output
Rationale: Angiotensin II increases blood pressure through
vasoconstriction and stimulation of aldosterone secretion.

Fill-in-the-Blank Questions
5. The pharmacodynamic effect of anticoagulants is to reduce
__________ formation.
ANS: Thrombus
Rationale: Anticoagulants prevent clot formation by
inhibiting clotting factors or platelets.
6. The hallmark pathophysiological change in asthma is
__________.
ANS: Airway inflammation
Rationale: Chronic inflammation leads to
bronchoconstriction and airway hyperresponsiveness in asthma.

, 7. The therapeutic goal in treating hypothyroidism is to
normalize levels of __________.
ANS: Thyroid hormones (T3 and T4)
Rationale: Restoring hormone levels ensures optimal
metabolic function.

True/False Questions
8. Selective serotonin reuptake inhibitors (SSRIs) increase
serotonin levels by blocking serotonin reabsorption into neurons.
ANS: True
Rationale: SSRIs block the reuptake of serotonin, enhancing
its availability in the synaptic cleft.
9. Nonsteroidal anti-inflammatory drugs (NSAIDs) primarily act
by inhibiting lipoxygenase enzymes.
ANS: False
Rationale: NSAIDs inhibit cyclooxygenase enzymes (COX-1
and COX-2), reducing prostaglandin production.
