A 65-year-old patient with chronic kidney disease is prescribed gentamicin.
Which action is most important before administering this drug?
A. Monitor liver enzymes
B. Assess blood glucose levels
C. Review renal function tests
D. Encourage increased fluid intake
Correct Answer: C. Review renal function tests
Rationale: Gentamicin is nephrotoxic and primarily excreted by the kidneys. Reduced
renal function increases the risk of toxicity, making renal monitoring essential.
A patient taking warfarin begins therapy with an antibiotic. Which outcome is the
nurse most concerned about?
A. Reduced antibiotic absorption
B. Increased risk of bleeding
C. Decreased warfarin levels
D. Hypertension
Correct Answer: B. Increased risk of bleeding
Rationale: Many antibiotics inhibit liver enzymes that metabolize warfarin, increasing its
effect and raising the risk of bleeding.
A patient reports dizziness and a dry mouth after starting a new medication.
These effects are best classified as:
,COMPREHENSIVE PHARMACOLOGY EXAM
QUESTIONS AND CORRECT ANSWERS
GUARANTEED PASS
A. Allergic reactions
B. Toxic effects
C. Side effects
D. Idiosyncratic reactions
Correct Answer: C. Side effects
Rationale: Dizziness and dry mouth are predictable, non-therapeutic effects that
commonly occur with many medications.
A nurse administers morphine for pain. Thirty minutes later, the patient reports
significant pain relief. This illustrates which pharmacologic concept?
A. Drug distribution
B. Therapeutic effect
C. Drug metabolism
D. Drug tolerance
Correct Answer: B. Therapeutic effect
Rationale: Therapeutic effect refers to the intended beneficial outcome of medication
administration.
A patient with asthma is prescribed a beta-blocker. Why should the nurse
question this order?
A. Beta-blockers increase blood pressure
B. Beta-blockers may trigger bronchoconstriction
C. Beta-blockers cause sedation
D. Beta-blockers reduce drug absorption
,COMPREHENSIVE PHARMACOLOGY EXAM
QUESTIONS AND CORRECT ANSWERS
GUARANTEED PASS
Correct Answer: B. Beta-blockers may trigger bronchoconstriction
Rationale: Non-selective beta-blockers block beta-2 receptors in the lungs, potentially
worsening asthma symptoms.
A patient states, “This medication is not working like it used to.” Which concept
does this best describe?
A. Dependence
B. Synergism
C. Tolerance
D. Allergy
Correct Answer: C. Tolerance
Rationale: Tolerance occurs when repeated use of a drug results in reduced
effectiveness over time.
A nurse gives a drug intravenously. Which pharmacokinetic phase is bypassed?
A. Distribution
B. Metabolism
C. Absorption
D. Excretion
Correct Answer: C. Absorption
Rationale: IV administration delivers the drug directly into circulation, eliminating the
absorption phase.

A patient taking digoxin develops nausea and visual disturbances. These findings
suggest:
A. Therapeutic effect
B. Drug allergy
C. Drug toxicity
D. Drug tolerance
Correct Answer: C. Drug toxicity
Rationale: Nausea and visual changes are classic signs of digoxin toxicity, which has a
narrow therapeutic index.
A nurse explains that a drug has a narrow therapeutic index. What does this
mean?
A. The drug works quickly
B. The drug has minimal side effects
C. Small dose changes can cause toxicity
D. The drug is rapidly excreted
Correct Answer: C. Small dose changes can cause toxicity
Rationale: Drugs with narrow therapeutic indices require careful monitoring because
the therapeutic dose is close to the toxic dose.
A patient is prescribed two drugs that compete for the same receptor site. One
drug reduces the effect of the other. This is known as:
