Questions 1–25
1. Which term describes the movement of a medication from its site of administration into the
bloodstream?
A) Absorption
B) Distribution
C) Metabolism
D) Excretion
Correct Answer: A. Absorption
Rationale: Absorption is the process by which a medication moves from its administration site into
systemic circulation. Distribution describes movement from the bloodstream into tissues. Metabolism
chemically alters medications, primarily in the liver, while excretion removes drugs and metabolites
from the body, most commonly through the kidneys.
2. Which organ is primarily responsible for metabolism of many medications?
A) Kidney
B) Liver
C) Pancreas
D) Spleen
Correct Answer: B. Liver
Rationale: The liver contains numerous enzymes, including the cytochrome P450 system, that
metabolize many medications. Hepatic impairment can therefore decrease drug metabolism and
increase toxicity risk. The kidneys are particularly important for excretion, whereas the pancreas and
spleen are not primary organs of medication metabolism.
3. Which term describes the time required for the amount of a medication in the body to
decrease by 50%?
A) Therapeutic index
B) Bioavailability
C) Half-life
D) Peak effect
Correct Answer: C. Half-life
Rationale: Half-life represents the time required for the amount or concentration of a medication to
decrease by approximately one half. It influences dosing frequency and the time needed to approach
steady state. Drug elimination, distribution, metabolism, and patient-specific organ function can
influence half-life.
4. Which route of medication administration generally provides 100% bioavailability?
, A) Oral
B) Subcutaneous
C) Intramuscular
D) Intravenous
Correct Answer: D. Intravenous
Rationale: Intravenous administration places medication directly into systemic circulation and
therefore provides complete bioavailability. Oral medications may undergo incomplete absorption
and first-pass metabolism. Subcutaneous and intramuscular medications must first be absorbed from
tissue before reaching systemic circulation.
5. What is the primary purpose of a loading dose?
A) Rapidly achieve a therapeutic drug concentration
B) Prevent all adverse reactions
C) Eliminate renal excretion
D) Shorten the medication's half-life
Correct Answer: A. Rapidly achieve a therapeutic drug concentration
Rationale: A loading dose is a relatively larger initial dose intended to reach an effective drug
concentration quickly. It can be useful when a medication has a long half-life and waiting for
repeated maintenance doses would delay therapeutic effects. Subsequent maintenance doses replace
medication eliminated from the body.
6. Which statement best describes an agonist?
A) It permanently destroys a receptor
B) It binds to a receptor and activates a physiologic response
C) It prevents all medication metabolism
D) It increases renal excretion of every drug
Correct Answer: B. It binds to a receptor and activates a physiologic response
Rationale: An agonist has affinity for a receptor and produces receptor activation, generating a
biologic response. An antagonist binds without producing the same activation and blocks or reduces
receptor-mediated effects. Partial agonists activate receptors but produce less maximal effect than
full agonists.
7. Which concept describes the relationship between a medication's effective dose and toxic
dose?
A) First-pass effect
B) Half-life
C) Therapeutic index
D) Bioavailability
Correct Answer: C. Therapeutic index
Rationale: The therapeutic index compares doses associated with therapeutic and toxic effects and
provides an indication of medication safety margin. Drugs with narrow therapeutic ranges require
particularly careful dosing and monitoring. Half-life concerns elimination time, while bioavailability
concerns the amount reaching systemic circulation.
