,Q1. A drug has a volume of distribution of 40 L and a clearance of 5 L/hour. If the
desired steady-state plasma concentration is 10 mg/L, what oral maintenance dose is
required every 6 hours, assuming 100% bioavailability?
A. 200 mg
B. 300 mg
C. 400 mg
D. 800 mg
Correct Answer: B. 300 mg
Rationale: Maintenance dose rate = clearance × target concentration = 5 L/hr × 10 mg/L
= 50 mg/hr. Over 6 hours, that equals 300 mg. Volume of distribution is irrelevant for
maintenance dosing; it affects loading dose.
Why Wrong:
A - 200 mg would be insufficient, as it corresponds to a dosing rate of 33.3 mg/hr,
below the required 50 mg/hr.
C - 400 mg overestimates the required amount, likely from incorrectly using volume
of distribution in the calculation.
D - 800 mg is a gross overestimate, possibly from multiplying clearance by volume or
using a wrong time interval.

Q2. Which genetic polymorphism significantly alters the metabolism of codeine,
leading to either therapeutic failure or life-threatening toxicity?
A. CYP2D6 ultra-rapid metabolizer phenotype
B. CYP3A4 poor metabolizer phenotype
C. N-acetyltransferase 2 slow acetylator phenotype
D. Pseudocholinesterase deficiency
Correct Answer: A. CYP2D6 ultra-rapid metabolizer phenotype
Rationale: CYP2D6 converts codeine to morphine; ultra-rapid metabolizers produce
excessive morphine, risking respiratory depression, while poor metabolizers get
inadequate analgesia. CYP3A4 is minor for this conversion.
Why Wrong:
B - CYP3A4 metabolizes many drugs but is not the primary enzyme for codeine
activation; its polymorphism has less impact on codeine efficacy.
C - NAT2 affects drugs like isoniazid and hydralazine, not codeine metabolism.
D - Pseudocholinesterase deficiency affects succinylcholine metabolism, not codeine.

, Q3. A patient on warfarin is started on rifampin for tuberculosis. How should the
nurse anticipate the international normalized ratio (INR) to change, and what dose
adjustment is likely needed?
A. INR decreases; warfarin dose may need to be increased.
B. INR increases; warfarin dose may need to be decreased.
C. INR remains unchanged; no dose adjustment is needed.
D. INR initially increases then stabilizes; no long-term change.
Correct Answer: A. INR decreases; warfarin dose may need to be increased.
Rationale: Rifampin is a potent CYP3A4 and CYP2C9 inducer, accelerating warfarin
metabolism, thus lowering INR. To maintain therapeutic anticoagulation, the warfarin
dose typically must be increased.
Why Wrong:
B - An increase in INR would be expected with an enzyme inhibitor, not an inducer
like rifampin.
C - Rifampin's induction effect is significant and almost always alters warfarin
requirements.
D - The effect is sustained while rifampin is taken; INR does not simply stabilize
without dose adjustment.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 30
Q4. A patient receiving an aminoglycoside develops acute kidney injury. Which
mechanism best explains this nephrotoxicity?
A. Direct tubular cell damage via phospholipidosis and mitochondrial dysfunction
B. Prerenal vasoconstriction leading to reduced glomerular filtration
C. Obstructive nephropathy from crystal deposition in the collecting ducts
D. Immune-mediated glomerulonephritis with antibody deposition
Correct Answer: A. Direct tubular cell damage via phospholipidosis and
mitochondrial dysfunction
Rationale: Aminoglycosides accumulate in proximal tubular cells, disrupting phospholipid
membranes and mitochondria, causing acute tubular necrosis. This is direct,
dose-dependent toxicity.
Why Wrong:
B - Prerenal vasoconstriction is more typical of NSAIDs or contrast nephropathy, not
aminoglycosides.
C - Crystal nephropathy is associated with sulfonamides or acyclovir, not
aminoglycosides.
D - Immune-mediated glomerulonephritis is not a primary mechanism for
aminoglycoside nephrotoxicity.
