Chapter 2: Rational Drug Selection and Prescription Writing
1. A 50-year-old man with hypertension is prescribed a new antihypertensive. The
provider considers cost, efficacy, and patient comorbidities before selecting the
drug. What principle is being applied?
A. Polypharmacy
B. Rational drug selection
C. Empirical prescribing
D. Brand preference
ANS: B
Rationale: Rational drug selection involves choosing medications based on
efficacy, safety, cost, and patient-specific factors, ensuring optimal therapeutic
outcomes.
2. A NP prescribes an antibiotic for a urinary tract infection. Which factor is most
important in rational drug selection?
A. Patient’s favorite pharmacy
B. Pathogen susceptibility and drug safety profile
C. Drug color and packaging
D. Prescriber convenience
ANS: B
Rationale: Rational prescribing considers the pathogen’s sensitivity, potential
adverse effects, and patient-specific factors to maximize safety and efficacy.
3. A PA writes a prescription but fails to document the indication. Which risk does
this pose?
A. Legal and safety concerns
B. Faster patient adherence
C. Reduced drug cost
D. Improved patient convenience
ANS: A
Rationale: Documentation of the indication is critical for legal compliance, patient
safety, and continuity of care.
4. A NP wants to prescribe a new antihypertensive. Which resource best supports
rational drug selection?
A. Clinical practice guidelines
B. Social media recommendations
C. Patient preference only
D. Pharmaceutical advertisements
ANS: A
Rationale: Evidence-based clinical practice guidelines provide recommendations
for selecting safe and effective medications based on current research.
, 5. A PA prescribes a medication without considering potential drug interactions.
Which principle is violated?
A. Rational drug selection
B. Brand loyalty
C. Generic prescribing
D. Telehealth prescribing
ANS: A
Rationale: Rational prescribing requires consideration of drug interactions to
prevent adverse events and ensure therapeutic efficacy.
6. A NP chooses a generic drug over a brand name equivalent. Which aspect of
rational drug selection does this illustrate?
A. Cost-effectiveness
B. Patient preference only
C. Marketing influence
D. Polypharmacy
ANS: A
Rationale: Rational drug selection considers cost-effectiveness, and generic
drugs provide the same efficacy at a lower cost.
7. A PA prescribes a drug for a patient with renal impairment. Which consideration
demonstrates rational prescribing?
A. Adjusting dose based on renal function
B. Prescribing standard adult dose for all patients
C. Ignoring lab results
D. Selecting brand name only
ANS: A
Rationale: Rational prescribing accounts for patient-specific factors such as
organ function to prevent toxicity and adverse events.
8. A NP prescribes an antibiotic empirically for suspected bacterial pneumonia.
What enhances rational prescribing?
A. Following culture and sensitivity results once available
B. Prescribing indefinitely without follow-up
C. Choosing based on patient preference alone
D. Selecting the newest drug on the market
ANS: A
Rationale: Empirical therapy should be adjusted based on culture results to
ensure efficacy and minimize resistance, reflecting rational prescribing principles.
9. A PA reviews a patient’s multiple medications before adding a new drug. Which
principle is demonstrated?
A. Avoiding polypharmacy
B. Ignoring drug interactions
