NR-565 ADVANCED PHARMACOLOGY FUNDAMENTALS MIDTERM & FINAL
PRACTICE EXAM — 200 QUESTIONS
1. Which receptor type is primarily responsible for the bronchodilation effects
of beta-2 agonists?
A. Alpha-1 adrenergic receptor
B. Alpha-2 adrenergic receptor
C. Beta-2 adrenergic receptor
D. Muscarinic receptor
E. Dopaminergic receptor
EXPERT RATIONALE: Beta-2 adrenergic receptors are located in bronchial smooth
muscle. Activation causes relaxation and bronchodilation, which is the basis for using
beta-2 agonists like albuterol in asthma.
2. A patient taking warfarin is prescribed trimethoprim-sulfamethoxazole.
What is the most likely drug interaction?
A. Decreased absorption of warfarin
,B. Increased renal excretion of warfarin
C. Increased anticoagulant effect of warfarin
D. Decreased protein binding of trimethoprim
E. Induction of CYP2C9 enzymes
EXPERT RATIONALE: TMP-SMX inhibits CYP2C9, the primary enzyme responsible for
warfarin metabolism, leading to elevated warfarin levels and increased bleeding risk.
3. Which of the following best describes the mechanism of action of ACE
inhibitors?
A. Block angiotensin II receptors directly
B. Inhibit renin release from the kidney
C. Prevent conversion of angiotensin I to angiotensin II
D. Block aldosterone synthesis in the adrenal cortex
E. Stimulate bradykinin breakdown
EXPERT RATIONALE: ACE inhibitors block angiotensin-converting enzyme, preventing
the formation of angiotensin II, which causes vasodilation, reduced aldosterone
secretion, and decreased blood pressure.
4. Which phase of pharmacokinetics refers to the biological transformation of
a drug?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
E. Elimination
, EXPERT RATIONALE: Metabolism (biotransformation) is the process by which the
body chemically alters a drug, primarily in the liver, to facilitate its elimination.
5. A nurse practitioner prescribes metformin for a patient with type 2
diabetes. What is the primary mechanism of action?
A. Stimulates insulin secretion from pancreatic beta cells
B. Blocks glucagon receptors in the liver
C. Decreases hepatic glucose production and improves insulin sensitivity
D. Inhibits alpha-glucosidase in the gut
E. Increases renal glucose excretion
EXPERT RATIONALE: Metformin primarily works by suppressing hepatic
gluconeogenesis and improving peripheral insulin sensitivity without causing
hypoglycemia or weight gain.
6. Which of the following antibiotics inhibits cell wall synthesis by binding to
penicillin-binding proteins?
A. Azithromycin
B. Ciprofloxacin
C. Amoxicillin
D. Doxycycline
E. Metronidazole
EXPERT RATIONALE: Amoxicillin, like all beta-lactam antibiotics, inhibits bacterial
cell wall synthesis by binding to penicillin-binding proteins (PBPs), causing cell lysis and
death.
7. What is the clinical significance of the first-pass effect?
, A. It increases drug bioavailability
B. It reduces renal clearance
C. It reduces the amount of drug reaching systemic circulation after oral
administration
D. It enhances drug absorption in the small intestine
E. It increases protein binding of the drug
EXPERT RATIONALE: After oral administration, drugs absorbed in the GI tract pass
through the liver via portal circulation, where significant metabolism can occur before
reaching systemic circulation, reducing bioavailability.
8. Which diuretic class is most likely to cause hypokalemia?
A. Potassium-sparing diuretics
B. Carbonic anhydrase inhibitors
C. Loop diuretics
D. Osmotic diuretics
E. Vasopressin antagonists
EXPERT RATIONALE: Loop diuretics like furosemide inhibit the Na-K-2Cl transporter
in the thick ascending loop of Henle, leading to significant potassium wasting and
hypokalemia.
9. A patient develops a dry, persistent cough after starting lisinopril. What is
the mechanism behind this side effect?
A. Increased angiotensin II levels
B. Direct irritation of the bronchial mucosa
C. Accumulation of bradykinin in the lungs
D. Reflex bronchoconstriction from hypotension
