Nursing pharmacology
1. The primary purpose of pharmacology in nursing practice is to:
A. Diagnose diseases
B. Understand medications and their effects on patients
C. Replace medical treatment
D. Prescribe all medications
Answer: B
Rationale: Pharmacology helps nurses understand drug actions, safe administration, adverse
effects, interactions, and patient education.
2. The generic name of a medication refers to:
A. The manufacturer’s brand name
B. The chemical formula only
C. The official nonproprietary name of the drug
D. A nickname used by patients
Answer: C
Rationale: The generic name is the standardized, noncommercial name assigned to a
medication.
3. A nurse understands that the brand name of a medication is:
A. The same worldwide
B. Assigned by the pharmaceutical company
C. The scientific chemical name
D. Always less expensive than generic drugs
Answer: B
,Rationale: Brand names are proprietary names created by manufacturers for marketing
purposes.
4. Pharmacokinetics refers to:
A. What the drug does to the body
B. What the body does to the drug
C. The emotional response to medication
D. Drug manufacturing processes
Answer: B
Rationale: Pharmacokinetics includes absorption, distribution, metabolism, and excretion of
medications.
5. Pharmacodynamics describes:
A. Drug movement through the body
B. Drug effects on body tissues and systems
C. Medication storage requirements
D. Drug pricing
Answer: B
Rationale: Pharmacodynamics explains how drugs produce therapeutic and adverse effects.
6. The process by which a medication enters the bloodstream is called:
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Answer: A
Rationale: Absorption is the movement of medication from its administration site into
circulation.
7. Which route generally provides the fastest medication absorption?
,A. Oral
B. Intravenous
C. Topical
D. Subcutaneous
Answer: B
Rationale: IV medications enter circulation directly, producing rapid effects.
8. The liver is the primary organ responsible for:
A. Drug metabolism
B. Drug absorption
C. Drug administration
D. Drug storage
Answer: A
Rationale: Many medications undergo hepatic metabolism before elimination.
9. The kidneys primarily contribute to medication:
A. Activation
B. Excretion
C. Absorption
D. Distribution

10. A drug half-life refers to:
A. Time required for a drug to reach peak effect
B. Time required for half of the drug to be eliminated

Answer: B
, Rationale: Half-life indicates how long it takes for plasma drug concentration to decrease by
50%.
11. The therapeutic range of a medication is:
A. The toxic dose level
B. The range where the drug produces desired effects without harmful effects
C. The maximum dose allowed
D. The smallest available dose
Answer: B
Rationale: Therapeutic range represents safe and effective drug concentrations.
12. A medication with a narrow therapeutic index requires:
A. Less monitoring
B. Careful monitoring of blood levels and effects
C. Administration only orally
D. No patient education

Rationale: Drugs with narrow therapeutic ranges can become toxic with small dosage changes.
13. The nurse should verify patient identity before medication administration using:

B. At least two patient identifiers
C. Medication color
D. Patient appearance
Answer: B
Rationale: Two identifiers reduce medication errors and improve patient safety.
