1. Which pharmacokinetic process describes movement of a
medication from the gastrointestinal tract into systemic
circulation?
A. Distribution
B. Metabolism
C. Absorption
D. Excretion
Answer: C. Absorption
Rationale: Absorption is the movement of a drug from its site of
administration into the systemic circulation.
2. Which route of administration provides 100% bioavailability?
A. Oral
B. Intramuscular
C. Subcutaneous
D. Intravenous
Answer: D. Intravenous
,Rationale: IV administration places the medication directly into
systemic circulation, giving it complete bioavailability.
3. A medication has a half-life of 8 hours. Approximately how long
will it take for most of the medication to be eliminated?
A. 8 hours
B. 16 hours
C. 24 hours
D. 40 hours
Answer: D. 40 hours
Rationale: Approximately 4–5 half-lives are required for most drugs
to be eliminated. Five half-lives of 8 hours equal 40 hours.
4. What is the primary purpose of a drug's loading dose?
A. Prevent renal elimination
B. Reach therapeutic concentrations rapidly
C. Reduce adverse effects
D. Increase hepatic metabolism
Answer: B. Reach therapeutic concentrations rapidly
Rationale: A loading dose is used when rapid achievement of a
therapeutic concentration is desired.
5. Which organ is primarily responsible for metabolism of many
medications?
A. Heart
B. Liver
C. Spleen
D. Pancreas
,Answer: B. Liver
Rationale: Hepatic enzymes, particularly the cytochrome P450
system, metabolize many medications.
6. Which pharmacokinetic process describes removal of drugs from
the body?
A. Absorption
B. Distribution
C. Elimination
D. Potentiation
Answer: C. Elimination
Rationale: Elimination encompasses drug metabolism and excretion
from the body.
7. A patient with severe renal impairment is prescribed a
medication primarily eliminated by the kidneys. What should the
clinician anticipate?
A. Increased drug clearance
B. Possible accumulation of the medication
C. Immediate drug absorption
D. Decreased bioavailability from IV administration
Answer: B. Possible accumulation of the medication
Rationale: Reduced renal clearance can increase drug concentrations
and toxicity risk, requiring dose or interval adjustment.
8. Which term describes the amount of drug required to produce a
particular therapeutic effect?
, A. Potency
B. Efficacy
C. Clearance
D. Bioavailability
Answer: A. Potency
Rationale: Potency refers to the amount of drug needed to produce a
specified effect. Efficacy refers to the maximum effect a drug can
produce.
9. Which statement best describes a competitive antagonist?
A. It activates the receptor fully
B. It permanently increases receptor activity
C. It competes with an agonist for receptor binding
D. It increases drug absorption
Answer: C. It competes with an agonist for receptor binding
Rationale: Competitive antagonists bind to receptors and prevent or
reduce agonist activity by competing for receptor sites.
10. Which patient factor can significantly alter medication
pharmacokinetics in older adults?
A. Increased total body water
B. Increased renal filtration
C. Reduced renal function
D. Increased hepatic blood flow
Answer: C. Reduced renal function
Rationale: Aging is commonly associated with reduced renal function,
which can decrease clearance of renally eliminated medications.
