,Q1. A drug with a high hepatic extraction ratio is administered orally. If the patient
develops cirrhosis with portacaval shunting, which of the following changes is most
expected?
A. Decreased oral bioavailability
B. Increased oral bioavailability
C. Decreased half-life
D. Increased renal clearance
Correct Answer: B. Increased oral bioavailability
Rationale: High extraction drugs undergo extensive first-pass metabolism. Cirrhosis with
portacaval shunting bypasses the liver, increasing systemic bioavailability. Half-life may
increase due to reduced metabolism, not decrease. Renal clearance is not directly affected.
Why Wrong:
A - Shunting reduces first-pass metabolism, thereby increasing, not decreasing,
bioavailability.
C - Reduced hepatic metabolism typically prolongs half-life.
D - Renal clearance is not directly altered by hepatic shunting.

Q2. Which of the following best explains why a drug that is a weak base with pKa 7.8
is more likely to accumulate in breast milk compared to plasma?
A. Ion trapping due to lower pH of breast milk
B. Higher lipid solubility of the ionized form
C. Active transport of the drug into milk
D. Reduced protein binding in milk
Correct Answer: A. Ion trapping due to lower pH of breast milk
Rationale: Weak bases ionize more in acidic environments (milk pH ~6.6 vs plasma 7.4),
leading to ion trapping and higher total drug concentration in milk. The ionized form is
less lipid-soluble, not more. Active transport is not a general mechanism. Protein binding
differences are not the primary cause.
Why Wrong:
B - Ionized forms are less lipid-soluble, not more.
C - Most drugs enter milk by passive diffusion, not active transport.
D - Milk has lower protein content, but ion trapping is the dominant factor.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 7
Q3. A patient on warfarin is prescribed metronidazole. Which mechanism primarily
explains the enhanced anticoagulant effect?
A. Displacement of warfarin from albumin
Page 3
, B. Inhibition of CYP2C9
C. Reduction of vitamin K absorption
D. Additive antiplatelet effect
Correct Answer: B. Inhibition of CYP2C9
Rationale: Metronidazole inhibits CYP2C9, the enzyme that metabolizes the S-enantiomer
of warfarin, increasing its levels and anticoagulant effect. Displacement is not significant
at clinically relevant doses. Metronidazole does not affect vitamin K absorption nor has
antiplatelet effects.
Why Wrong:
A - Protein binding displacement is transient and rarely causes clinically significant
interactions.
C - Metronidazole does not interfere with vitamin K absorption.
D - Metronidazole has no antiplatelet activity.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 24
Q4. A patient is receiving an opioid agonist-antagonist (e.g., pentazocine)
concurrently with morphine. Which outcome is expected if the pentazocine is given
before the morphine?
A. Potentiation of morphine's analgesic effect
B. Reduction of morphine's analgesic effect
C. No change in morphine's effect
D. Increased risk of respiratory depression
Correct Answer: B. Reduction of morphine's analgesic effect
Rationale: Pentazocine is a partial agonist at mu receptors and an agonist at kappa
receptors. When given before a full agonist like morphine, it occupies mu receptors
without full activation, thereby antagonizing morphine's analgesic effect. This can
precipitate withdrawal in dependent patients. It does not potentiate or leave unchanged;
respiratory depression risk is not increased.
Why Wrong:
A - It blocks mu receptors, so it reduces rather than potentiates morphine's effect.
C - It occupies mu receptors, so it does alter morphine's effect.
D - It is a partial agonist, so it can precipitate withdrawal but not increase respiratory
depression.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 33
Q5. Which of the following is the primary mechanism of action of loop diuretics in the
treatment of acute pulmonary edema?
A. Inhibition of the Na+-K+-2Cl- cotransporter in the thick ascending limb
B. Antagonism of aldosterone receptors in the collecting duct
