1. A patient is prescribed a drug that is a known CYP3A4 inducer. How would this most likely
affect a co-administered drug that is a substrate of the same enzyme?
A. It would increase the plasma concentration of the substrate drug.
B. It would decrease the rate of excretion of the substrate drug.
C. It would have no effect on the substrate drug’s metabolism.
D. It would decrease the plasma concentration of the substrate drug.
Answer: D
Conceptual Explanation: Enzyme inducers increase the activity of metabolic enzymes
(like CYP3A4), leading to faster metabolism and lower plasma levels of substrate drugs.
2. Which characteristic of a drug allows it to cross the blood-brain barrier (BBB) most
effectively?
A. High water solubility
B. High lipid solubility
C. Highly ionized state
,D. Large molecular weight
Answer: B
Conceptual Explanation: The BBB is composed of tight junctions and a lipid-rich
environment; therefore, highly lipid-soluble (lipophilic) drugs cross more easily.
3. A patient taking Lisinopril develops a persistent, dry cough. What is the physiological
mechanism behind this side effect?
A. Inhibition of prostaglandin synthesis
B. Direct irritation of the bronchial mucosa
C. Accumulation of bradykinin in the lungs
D. Increased levels of Angiotensin II
Answer: C
Conceptual Explanation: ACE inhibitors prevent the breakdown of bradykinin. The
resulting accumulation of bradykinin in the respiratory tract causes the characteristic dry
cough.
4. Which of the following beta-blockers is considered ‘cardioselective,’ primarily targeting
Beta-1 receptors?
A. Propranolol
B. Nadolol
C. Metoprolol
, D. Carvedilol
Answer: C
Conceptual Explanation: Metoprolol and Atenolol are cardioselective beta-blockers.
Propranolol and Nadolol are non-selective, and Carvedilol blocks both alpha and beta
receptors.
5. A patient with Type 2 Diabetes is started on Metformin. What is the primary mechanism of
action for this medication?
A. Stimulating insulin secretion from pancreatic beta cells
B. Decreasing hepatic glucose production
C. Increasing glucose uptake in the kidneys
D. Slowing the absorption of carbohydrates in the gut
Answer: B
Conceptual Explanation: Metformin works primarily by decreasing gluconeogenesis in
the liver and improving insulin sensitivity in peripheral tissues.
6. Which laboratory value must be closely monitored in a patient taking Spironolactone?
A. Serum Sodium
B. Serum Magnesium
C. Serum Calcium
D. Serum Potassium
