,Q1. A patient with chronic kidney disease (eGFR 25 mL/min) requires antimicrobial
therapy. Which pharmacokinetic principle most directly informs the need for dosage
adjustment?
A. First-pass hepatic metabolism
B. Volume of distribution and protein binding
C. Active renal tubular secretion and glomerular filtration
D. Enterohepatic recirculation
Correct Answer: C. Active renal tubular secretion and glomerular filtration
Rationale: Renal impairment reduces clearance of drugs that are eliminated by
glomerular filtration and tubular secretion, requiring dose reduction to avoid
accumulation and toxicity. Volume of distribution and protein binding affect distribution,
not primarily elimination. First-pass metabolism and enterohepatic recirculation are
hepatic processes.
Why Wrong:
A - First-pass metabolism is hepatic and not the primary determinant for renal dosing.
B - Volume of distribution and protein binding affect distribution, not renal
elimination.
D - Enterohepatic recirculation prolongs action but is not the key factor in renal
impairment.

Q2. Which receptor-mediated effect is most likely to occur when a nonselective
beta-blocker is administered to a patient with asthma?
A. Bronchodilation due to beta-2 agonism
B. Bronchoconstriction due to beta-2 blockade
C. Increased mucus secretion due to muscarinic stimulation
D. Reduced cough reflex due to beta-1 blockade
Correct Answer: B. Bronchoconstriction due to beta-2 blockade
Rationale: Nonselective beta-blockers block beta-2 receptors in the airways, leading to
bronchoconstriction, which can exacerbate asthma. Beta-2 agonism would cause
bronchodilation, not blockade. Muscarinic stimulation increases secretions but is not a
beta-blocker effect. Beta-1 blockade affects the heart, not cough reflex.
Why Wrong:
A - Beta-blockers are antagonists, not agonists, so they do not cause bronchodilation.
C - Muscarinic stimulation is not a beta-blocker mechanism.
D - Beta-1 blockade is cardiospecific and does not affect cough reflex.

, Q3. A drug has a half-life of 6 hours and is administered intravenously every 6 hours.
Approximately how many half-lives are required to reach steady-state concentration?
A. 2
B. 3
C. 5
D. 7
Correct Answer: C. 5
Rationale: Steady state is achieved after approximately 4-5 half-lives regardless of dosing
interval. After 5 half-lives, the drug concentration reaches about 97% of steady state. Two
to three half-lives achieve only 75-87.5%, not full steady state. Seven is more than
necessary.
Why Wrong:
A - Two half-lives achieve only 75% of steady state.
B - Three half-lives achieve about 87.5%.
D - Seven half-lives exceed the standard 4-5 needed.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 4
Q4. Which drug interaction mechanism is exemplified by the co-administration of a
CYP3A4 inducer and a CYP3A4 substrate?
A. Increased plasma concentration of the substrate
B. Decreased plasma concentration of the substrate
C. Competitive antagonism at the receptor
D. Altered renal excretion of the substrate
Correct Answer: B. Decreased plasma concentration of the substrate
Rationale: A CYP3A4 inducer increases the metabolism of a substrate, leading to
decreased plasma concentration and potentially reduced efficacy. Increased concentration
is typical of inhibitors. Receptor antagonism is pharmacodynamic, not metabolic. Renal
excretion is not the primary effect of enzyme induction.
Why Wrong:
A - Increased concentration is caused by CYP inhibition, not induction.
C - Receptor antagonism is a pharmacodynamic interaction, not metabolic.
D - Enzyme induction primarily affects hepatic metabolism, not renal excretion.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 5
Q5. A patient is receiving a medication that is a weak acid (pKa 4.4). In which
compartment will the drug be most ionized and thus less likely to cross membranes?
A. Gastric fluid (pH 1.5)
B. Plasma (pH 7.4)
