NR565 ADVANCED PHARMACOLOGY
COMPREHENSIVE EXAM REVIEW
QUESTIONS AND VERIFIED ANSWERS
(2026/ 2027 UPDATE)- CHAMBERLAIN
1. A patient taking Lisinopril for hypertension develops a persistent, dry, non-productive
cough. What is the physiological mechanism responsible for this adverse effect?
A. Inhibition of prostaglandin synthesis in the lungs
B. Accumulation of bradykinin and substance P
C. Direct stimulation of the vagus nerve in the larynx
D. Decreased production of nitric oxide in the bronchi
Answer: B
Conceptual Explanation: ACE inhibitors block the breakdown of bradykinin and
substance P, leading to their accumulation in the respiratory tract, which triggers a dry
cough in approximately 10-20% of patients.
2. Metformin is a first-line agent for Type 2 Diabetes. At what estimated Glomerular Filtration
Rate (eGFR) is Metformin strictly contraindicated due to the risk of lactic acidosis?
A. eGFR < 60 mL/min/1.73m²
B. eGFR < 30 mL/min/1.73m²
,C. eGFR < 45 mL/min/1.73m²
D. eGFR < 15 mL/min/1.73m²
Answer: B
Conceptual Explanation: Metformin is contraindicated in patients with an eGFR less than
30 mL/min/1.73m² because impaired renal clearance significantly increases the risk of
metformin-associated lactic acidosis (MALA).
3. Which of the following describes the mechanism of action of Warfarin (Coumadin)?
A. Direct inhibition of Thrombin (Factor IIa)
B. Inhibition of Vitamin K epoxide reductase
C. Activation of Antithrombin III
D. Direct inhibition of Factor Xa
Answer: B
Conceptual Explanation: Warfarin inhibits the enzyme Vitamin K epoxide reductase,
thereby preventing the recycling of Vitamin K and the subsequent synthesis of Vitamin K-
dependent clotting factors II, VII, IX, and X.
4. A patient with a history of severe asthma requires a beta-blocker for heart failure
management. Which medication is most appropriate due to its beta-1 selectivity?
A. Propranolol
B. Metoprolol Succinate
, C. Carvedilol
D. Nadolol
Answer: B
Conceptual Explanation: Metoprolol is a cardioselective beta-1 blocker. Non-selective
beta-blockers like Propranolol or Carvedilol (alpha/beta) can cause bronchoconstriction by
blocking beta-2 receptors in the lungs.
5. What is the primary monitoring parameter for a patient starting Atorvastatin to assess for
potential rhabdomyolysis if they report muscle pain?
A. Alanine aminotransferase (ALT)
B. Creatine Kinase (CK)
C. Serum Creatinine
D. Thyroid Stimulating Hormone (TSH)
Answer: B
Conceptual Explanation: Creatine Kinase (CK) levels should be checked if a patient on a
statin experiences unexplained muscle pain, tenderness, or weakness to rule out myopathy
or rhabdomyolysis.
6. Which electrolyte imbalance significantly increases the risk of Digoxin toxicity?
A. Hypokalemia
B. Hyperkalemia
