,1. Which term describes the study of how drugs produce their
effects in the body?
A. Pharmacokinetics
B. Pharmacognosy
C. Pharmacodynamics
D. Toxicology
Rationale: Pharmacodynamics describes what a drug does to the
body, including its mechanisms and effects.
2. Which process describes absorption, distribution, metabolism,
and excretion of a drug?
A. Pharmacodynamics
B. Pharmacokinetics
C. Pharmacogenomics
D. Pharmacotherapy
Rationale: Pharmacokinetics describes what the body does to a drug.
3. A nurse understands that the generic name of a medication is:
A. Assigned by the manufacturer
B. Always capitalized
C. A proprietary name
D. The standardized nonproprietary name
Rationale: Generic names are standardized and are not owned by a
pharmaceutical company.
4. Which route generally provides the fastest systemic drug effect?
A. Oral
B. Subcutaneous
C. Intramuscular
D. Intravenous
Rationale: IV administration places the medication directly into the
bloodstream.
,5. Which organ is primarily responsible for drug metabolism?
A. Kidney
B. Heart
C. Liver
D. Pancreas
Rationale: The liver is the major site of biotransformation for many
medications.
6. Which organ is most important for excreting many drug
metabolites?
A. Liver
B. Kidneys
C. Lungs
D. Spleen
Rationale: The kidneys eliminate many medications and metabolites
through urine.
7. A medication with a short half-life generally requires:
A. Less frequent administration
B. More frequent administration
C. No monitoring
D. A larger therapeutic index
Rationale: Drugs with short half-lives are eliminated relatively quickly
and may require more frequent dosing.
8. What does a drug's therapeutic index help indicate?
A. Its absorption rate
B. Its route of administration
C. Its relative margin of safety
D. Its protein-binding ability
Rationale: The therapeutic index compares toxic and therapeutic
doses and helps estimate drug safety.
, 9. A drug that binds to a receptor and produces a response is called
a:
A. Antagonist
B. Inhibitor
C. Agonist
D. Catalyst
Rationale: An agonist activates a receptor and produces a
pharmacologic response.
10. A drug that blocks the action of another drug at a receptor is
a(n):
A. Agonist
B. Antagonist
C. Enzyme
D. Hormone
Rationale: An antagonist binds to a receptor without activating it and
prevents or reduces another drug's action.
11. Which factor can significantly alter medication response in an
older adult?
A. Increased renal function
B. Increased total body water
C. Reduced hepatic and renal function
D. Increased drug metabolism
Rationale: Aging may reduce hepatic metabolism and renal
elimination, increasing exposure to some drugs.
12. What is the primary purpose of obtaining a medication history?
A. To determine the patient's income
B. To identify allergies and potential medication-related problems
C. To determine the patient's diagnosis only
D. To replace laboratory testing
