1. Prescriptive Authority & Safe Prescribing
1. Which statement best describes medication reconciliation?
A. comparing the documented list with what the patient actually takes
B. A condition unrelated to medication therapy
C. A medication storage rule only
Lehne's Pharmacotherapeutics — 500 Practice Questions Page 1
, D. A diagnosis that never affects treatment
ANS: A
Rationale: Comparing the documented list with what the patient actually takes. This matters because identifies omissions,
duplications, interactions, and discrepancies.
2. A clinician is reviewing a patient and encounters medication reconciliation. What is the most appropriate focus?
A. Apply the principle of medication reconciliation to the patient's medication plan
B. Ignore it because medication effects are identical in all patients
C. Automatically double every medication
D. Stop all therapy without assessment
ANS: A
Rationale: The key point is to comparing the documented list with what the patient actually takes. Identifies omissions,
duplications, interactions, and discrepancies.
3. Which statement best describes renal function?
A. assessing kidney function before dosing renally cleared drugs
B. A condition unrelated to medication therapy
C. A medication storage rule only
D. A diagnosis that never affects treatment
ANS: A
Rationale: Assessing kidney function before dosing renally cleared drugs. This matters because reduced clearance can
increase exposure and toxicity.
4. A clinician is reviewing a patient and encounters renal function. What is the most appropriate focus?
A. Apply the principle of renal function to the patient's medication plan
B. Ignore it because medication effects are identical in all patients
C. Automatically double every medication
D. Stop all therapy without assessment
ANS: A
Rationale: The key point is to assessing kidney function before dosing renally cleared drugs. Reduced clearance can increase
exposure and toxicity.
5. Which statement best describes hepatic function?
A. considering liver function when selecting hepatically cleared drugs
B. A condition unrelated to medication therapy
C. A medication storage rule only
D. A diagnosis that never affects treatment
ANS: A
Rationale: Considering liver function when selecting hepatically cleared drugs. This matters because impaired metabolism can
alter exposure and safety.

A. Apply the principle of hepatic function to the patient's medication plan
Lehne's Pharmacotherapeutics — 500 Practice Questions Page 2
, B. Ignore it because medication effects are identical in all patients
C. Automatically double every medication
D. Stop all therapy without assessment
ANS: A
Rationale: The key point is to considering liver function when selecting hepatically cleared drugs. Impaired metabolism can alter
exposure and safety.
7. Which statement best describes allergy verification?
A. checking the allergy history before prescribing
B. A condition unrelated to medication therapy
C. A medication storage rule only
D. A diagnosis that never affects treatment
ANS: A
Rationale: Checking the allergy history before prescribing. This matters because prevents avoidable exposure to a culprit
medication.
8. A clinician is reviewing a patient and encounters allergy verification. What is the most appropriate focus?
A. Apply the principle of allergy verification to the patient's medication plan
B. Ignore it because medication effects are identical in all patients
C. Automatically double every medication
D. Stop all therapy without assessment
ANS: A
Rationale: The key point is to checking the allergy history before prescribing. Prevents avoidable exposure to a culprit
medication.
9. Which statement best describes complete prescription?
A. including drug, strength, dose, route, frequency, and duration when appropriate
B. A condition unrelated to medication therapy
C. A medication storage rule only
D. A diagnosis that never affects treatment
ANS: A
Rationale: Including drug, strength, dose, route, frequency, and duration when appropriate. This matters because clear orders
reduce administration and dispensing errors.
10. A clinician is reviewing a patient and encounters complete prescription. What is the most appropriate focus?
A. Apply the principle of complete prescription to the patient's medication plan
B. Ignore it because medication effects are identical in all patients
C. Automatically double every medication
D. Stop all therapy without assessment
ANS: A
Rationale: The key point is to including drug, strength, dose, route, frequency, and duration when appropriate. Clear orders
reduce administration and dispensing errors.

, 11. Which statement best describes indication?
A. documenting why a medication is being prescribed
B. A condition unrelated to medication therapy
C. A medication storage rule only
D. A diagnosis that never affects treatment
ANS: A
Rationale: Documenting why a medication is being prescribed. This matters because supports future reassessment of whether
therapy remains necessary.
12. A clinician is reviewing a patient and encounters indication. What is the most appropriate focus?
A. Apply the principle of indication to the patient's medication plan
B. Ignore it because medication effects are identical in all patients
C. Automatically double every medication
D. Stop all therapy without assessment
ANS: A
Rationale: The key point is to documenting why a medication is being prescribed. Supports future reassessment of whether
therapy remains necessary.
13. Which statement best describes polypharmacy review?
A. reassessing whether every medication still has a clear indication
B. A condition unrelated to medication therapy
C. A medication storage rule only
D. A diagnosis that never affects treatment
ANS: A
Rationale: Reassessing whether every medication still has a clear indication. This matters because reduces unnecessary
medication exposure.
14. A clinician is reviewing a patient and encounters polypharmacy review. What is the most appropriate focus?
A. Apply the principle of polypharmacy review to the patient's medication plan
B. Ignore it because medication effects are identical in all patients
C. Automatically double every medication
D. Stop all therapy without assessment
ANS: A
Rationale: The key point is to reassessing whether every medication still has a clear indication. Reduces unnecessary
medication exposure.
15. Which statement best describes teach-back?
A. asking the patient to explain instructions in their own words
B. A condition unrelated to medication therapy
C. A medication storage rule only
D. A diagnosis that never affects treatment
ANS: A
