100 Questions with Correct Answers and Rationales
Questions 1–20: Pharmacology Fundamentals & Medication
Safety
1. Pharmacology is best defined as the study of:
A. Human anatomy
B. Drugs and their effects on living organisms
C. Surgical procedures
D. Microorganisms only
Correct Answer: B
Rationale: Pharmacology is the study of drugs, including their actions, effects, therapeutic uses,
and adverse effects.
2. Pharmacokinetics describes:
A. What the drug does to the body
B. What the body does to the drug
C. How drugs are named
D. How drugs are manufactured
,Correct Answer: B
Rationale: Pharmacokinetics includes absorption, distribution, metabolism, and excretion of
drugs.
3. Pharmacodynamics refers to:
A. Drug absorption
B. Drug elimination
C. What a drug does to the body
D. Drug storage
Correct Answer: C
Rationale: Pharmacodynamics describes the biochemical and physiologic effects of drugs and
their mechanisms of action.
4. Which route generally provides the fastest systemic drug effect?
A. Oral
B. Intravenous
C. Subcutaneous
D. Topical
Correct Answer: B
Rationale: IV administration delivers the drug directly into the bloodstream, providing rapid
systemic availability.
5. The term "therapeutic effect" refers to:
A. An unintended harmful effect
B. The desired clinical response to a medication
C. A medication error
D. A toxic reaction
Correct Answer: B
Rationale: The therapeutic effect is the intended beneficial response produced by a medication.
,6. Which medication error is most likely to occur when two drugs have similar
names?
A. Wrong-route error
B. Look-alike/sound-alike medication error
C. Calculation error
D. Documentation error
Correct Answer: B
Rationale: Similar drug names can contribute to look-alike/sound-alike errors.
7. Before administering a medication, the nurse should first:
A. Assume the prescription is correct
B. Verify the medication order and patient identity
C. Ask another patient for confirmation
D. Skip allergy assessment
Correct Answer: B
Rationale: Safe medication administration begins with verifying the order and correctly
identifying the patient.
8. Which patient identifier is most appropriate?
A. Room number only
B. Diagnosis only
C. Two approved patient identifiers
D. Bed location only
Correct Answer: C
Rationale: Using two approved identifiers reduces the risk of administering medications to the
wrong patient.
9. A medication prescribed "PRN" should be administered:
, A. Automatically every morning
B. Only when the specified indication or need is present
C. Every hour
D. Only at discharge
Correct Answer: B
Rationale: PRN medications are administered as needed according to the prescription and
clinical indication.
10. Which action best reduces medication errors during transitions of care?
A. Medication reconciliation
B. Avoiding patient questions
C. Discontinuing all home medications
D. Relying solely on memory
Correct Answer: A
Rationale: Medication reconciliation compares medication lists across transitions to identify
discrepancies and prevent errors.
11. Which factor can significantly alter medication response in an older adult?
A. Age-related changes in renal and hepatic function
B. Hair color
C. Hand dominance
D. Eye color
Correct Answer: A
Rationale: Aging can affect drug metabolism and elimination, increasing the risk of
accumulation and adverse effects.
12. A drug that produces a desired effect at a lower dose than another drug is
considered more:
A. Potent
B. Toxic
