Questions 1–10: Pharmacokinetics, Pharmacodynamics & Safe
Prescribing
Q1.
A 72-year-old patient with chronic kidney disease (eGFR 28 mL/min/1.73 m²) requires
initiation of an antibiotic that is primarily eliminated through the kidneys. Which
prescribing strategy best minimizes toxicity while maintaining efficacy?
,A. Prescribe the standard adult dose without adjustment.
B. Increase the dosing frequency.
C. Adjust the dose or dosing interval according to renal function.
D. Double the loading dose and maintain the usual schedule.
Correct Answer: C. Adjust the dose or dosing interval according to renal function.
Explanation: Reduced renal clearance can lead to drug accumulation and toxicity. Dose
adjustment or extending the dosing interval is the preferred strategy for many renally
eliminated medications. Standard dosing increases toxicity risk, increasing frequency
worsens accumulation, and doubling the loading dose is generally unnecessary unless
specifically indicated.
Q2.
A medication has a high first-pass effect. Which route of administration would most
effectively bypass hepatic first-pass metabolism?
A. Oral
B. Sublingual
C. Rectal (upper rectum)
D. Enteral feeding tube
Correct Answer: B. Sublingual
Explanation: Sublingual administration allows rapid absorption directly into the
systemic circulation, avoiding hepatic first-pass metabolism. Oral and feeding-tube
administration undergo gastrointestinal absorption before portal circulation. Rectal
administration only partially bypasses first-pass metabolism.
Q3.
,A patient taking warfarin is prescribed trimethoprim-sulfamethoxazole. What is the
most appropriate clinical action?
A. No monitoring is necessary.
B. Increase the warfarin dose.
C. Monitor INR closely because anticoagulant effects may increase.
D. Discontinue warfarin permanently.
Correct Answer: C. Monitor INR closely because anticoagulant effects may
increase.
Explanation: Trimethoprim-sulfamethoxazole inhibits warfarin metabolism and may
significantly increase INR and bleeding risk. Careful INR monitoring and dose
adjustment are recommended.
Q4.
Which pharmacokinetic parameter best describes the proportion of an administered
drug reaching systemic circulation unchanged?
A. Clearance
B. Volume of distribution
C. Bioavailability
D. Half-life
Correct Answer: C. Bioavailability
Explanation: Bioavailability represents the fraction of a drug that reaches systemic
circulation unchanged after administration. Clearance reflects elimination, volume of
distribution describes tissue distribution, and half-life measures the time for plasma
concentration to decrease by 50%.
, Q5.
A patient reports taking several herbal supplements while beginning antihypertensive
therapy. Which response by the clinician is most appropriate?
A. Advise stopping all supplements immediately.
B. Ignore supplement use because natural products are always safe.
C. Review all supplements for potential interactions before prescribing.
D. Delay treatment indefinitely.
Correct Answer: C. Review all supplements for potential interactions before
prescribing.
Explanation: Many herbal supplements interact with prescription medications through
pharmacokinetic or pharmacodynamic mechanisms. A medication reconciliation helps
identify clinically important interactions while supporting safe prescribing.
Q6.
Which factor most commonly increases the risk of adverse drug reactions in older
adults?
A. Increased hepatic blood flow
B. Reduced polypharmacy
C. Multiple comorbidities and altered drug clearance
D. Faster renal elimination
Correct Answer: C. Multiple comorbidities and altered drug clearance
Explanation: Older adults often experience reduced renal and hepatic function, altered
pharmacokinetics, and polypharmacy, all of which increase the likelihood of adverse
drug reactions.
