1. Foundations of Pharmacology
TEST BANK-STYLE PRACTICE SECTION
1. Which term describes the study of how a drug produces its effects in the body?
A. Pharmacokinetics
B. Pharmacodynamics
C. Pharmacogenetics
D. Pharmaceutics
ANSWER: B
Rationale: Pharmacodynamics examines drug actions and the relationship between drug concentration and effect.
DIF: Cognitive Level: Comprehension REF: Drug action TOP: Nursing Process: Implementation MSC: NCLEX Client Needs: Physiologic Integrity
2. Which pharmacokinetic process describes movement of a drug from the administration site into the bloodstream?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
ANSWER: A
Rationale: Absorption is the movement of a drug from its site of administration into systemic circulation.
DIF: Cognitive Level: Comprehension REF: Pharmacokinetics TOP: Nursing Process: Implementation MSC: NCLEX Client Needs: Physiologic
Integrity
3. A nurse explains that a drug with a narrow therapeutic index requires especially careful monitoring because:
A. it has no adverse effects
B. the therapeutic and toxic concentrations are relatively close
C. it is always given intravenously
D. it cannot be metabolized
ANSWER: B
Rationale: A narrow therapeutic index means there is a relatively small margin between effective and toxic concentrations.
DIF: Cognitive Level: Analysis REF: Therapeutic index TOP: Nursing Process: Evaluation MSC: NCLEX Client Needs: Physiologic Integrity
4. Which characteristic best describes an ideal medication?
A. Unpredictable effects
B. A wide safety margin
C. Permanent action
D. Only one route of administration
ANSWER: B
Rationale: An ideal drug has predictable effects, a useful therapeutic response, and a reasonable margin of safety.
DIF: Cognitive Level: Comprehension REF: Properties of drugs TOP: Nursing Process: Assessment MSC: NCLEX Client Needs: Physiologic Integrity
5. A patient asks why two people receiving the same medication may have different responses. Which factor is most relevant?
A. Individual genetic variation
B. The color of the tablet
C. The package design
Original Pharmacology Practice Test • 600 Questions • Page 3
, D. The drug's trade name
ANSWER: A
Rationale: Genetic and physiologic differences can alter drug metabolism, sensitivity, and response.
DIF: Cognitive Level: Analysis REF: Individual variation TOP: Nursing Process: Assessment MSC: NCLEX Client Needs: Physiologic Integrity
6. Which statement best describes a drug's efficacy?
A. The dose needed to produce an effect
B. The maximum effect a drug can produce
C. How quickly a tablet dissolves
D. The percentage excreted unchanged
ANSWER: B
Rationale: Efficacy refers to the greatest therapeutic effect a drug can produce.
DIF: Cognitive Level: Comprehension REF: Drug efficacy TOP: Nursing Process: Evaluation MSC: NCLEX Client Needs: Physiologic Integrity
7. Which term describes the amount of drug needed to produce a particular response?
A. Potency
B. Efficacy
C. Half-life
D. Clearance
ANSWER: A
Rationale: Potency refers to the amount of drug required to produce a given effect.
DIF: Cognitive Level: Comprehension REF: Potency TOP: Nursing Process: Assessment MSC: NCLEX Client Needs: Physiologic Integrity
8. A patient reports a new symptom after starting a medication. What should the nurse do first?
A. Assume the symptom is unrelated
B. Assess the symptom and relevant medication history
C. Tell the patient to stop all medications
D. Document without further assessment
ANSWER: B
Rationale: Assessment of the symptom, timing, dose, and other medications helps determine whether an adverse drug effect may be
occurring.
DIF: Cognitive Level: Analysis REF: Adverse effects TOP: Nursing Process: Assessment MSC: NCLEX Client Needs: Physiologic Integrity
9. Which route generally provides the fastest systemic drug effect?
A. Oral
B. Intravenous
C. Topical
D. Rectal
ANSWER: B
Rationale: Intravenous administration places the drug directly into systemic circulation and usually produces the most rapid onset.
DIF: Cognitive Level: Comprehension REF: Routes of administration TOP: Nursing Process: Implementation MSC: NCLEX Client Needs: Physiologic
Integrity
10. A medication is prescribed at a dose that appears unusually high. What is the safest nursing action?
A. Administer it immediately
B. Compare the order with the reference and clarify the prescription if needed
C. Reduce the dose independently
