,Q1. A patient with chronic kidney disease (CrCl 25 mL/min) requires a new antibiotic
for a severe infection. Which pharmacokinetic parameter is MOST critical to adjust
dosing to prevent toxicity?
A. Volume of distribution (Vd)
B. Clearance (CL)
C. Bioavailability (F)
D. Half-life (t1/2)
Correct Answer: B. Clearance (CL)
Rationale: Clearance reflects the efficiency of drug elimination, primarily renal in this
case. In CKD, reduced clearance leads to drug accumulation, so dosing adjustments are
based on creatinine clearance. Half-life is a derived parameter, but clearance is the
primary determinant of maintenance dose. Vd and F affect loading dose and absorption,
not elimination.
Why Wrong:
A - Vd affects the loading dose, not maintenance dosing adjustments for renal
impairment.
C - Bioavailability affects the fraction absorbed, not the elimination rate.
D - Half-life is a consequence of clearance and Vd, not the primary parameter for dose
adjustment.

Q2. A patient is on a medication that is a CYP3A4 inducer. Which of the following
co-administered drugs is MOST likely to have reduced efficacy due to increased
metabolism?
A. Warfarin
B. Diltiazem
C. Ketoconazole
D. Grapefruit juice
Correct Answer: A. Warfarin
Rationale: Warfarin is a substrate of CYP3A4; an inducer would increase its metabolism,
lowering plasma levels and anticoagulant effect. Diltiazem and ketoconazole are CYP3A4
inhibitors, and grapefruit juice also inhibits CYP3A4, so they would increase levels of
substrates, not decrease.
Why Wrong:
B - Diltiazem is a CYP3A4 inhibitor, not a substrate that would lose efficacy.
C - Ketoconazole is a strong CYP3A4 inhibitor, not a substrate.
D - Grapefruit juice inhibits CYP3A4, so it would increase, not decrease, levels of
substrates.

Q3. A patient with type 2 diabetes and heart failure is prescribed pioglitazone. Which
adverse effect makes this drug contraindicated?
A. Hypoglycemia
B. Fluid retention exacerbating heart failure
C. Weight gain
D. Lactic acidosis
Correct Answer: B. Fluid retention exacerbating heart failure
Rationale: Pioglitazone is a thiazolidinedione that can cause fluid retention and edema,
which can worsen heart failure. It is contraindicated in patients with NYHA class III/IV
heart failure. Hypoglycemia is uncommon with TZDs, weight gain is a concern but not the
primary contraindication, and lactic acidosis is associated with metformin.
Why Wrong:
A - Pioglitazone rarely causes hypoglycemia as monotherapy.
C - Weight gain is a side effect but not the reason for contraindication in heart failure.
D - Lactic acidosis is a hallmark of metformin, not pioglitazone.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 46
Q4. A patient is taking a drug that is a weak base. In which compartment will the
drug MOST likely accumulate?
A. Plasma (pH 7.4)
B. Gastric juice (pH 1.5)
C. Breast milk (pH 6.8)
D. Urine (pH 5.5)
Correct Answer: B. Gastric juice (pH 1.5)
Rationale: Weak bases are more lipid-soluble in alkaline environments, but they become
ionized (trapped) in acidic compartments. The gastric juice is highly acidic, so a weak
base will ionize and be trapped there, leading to accumulation. Plasma and breast milk
are less acidic, so trapping is less pronounced.
Why Wrong:
A - Plasma is slightly alkaline, so weak bases are more unionized and can diffuse out.
C - Breast milk is slightly acidic, but less so than gastric juice, so trapping is less.
D - Urine pH can vary, but acidic urine does trap weak bases, but not as consistently
as gastric juice.

Q5. A patient is a poor metabolizer of CYP2D6. Which of the following drugs is
MOST likely to cause toxicity at standard doses?
