SECTION I — INTRODUCTION & PHARMACOLOGY FOUNDATIONS
Questions 1–40
Question 1
,Which statement best describes pharmacokinetics?
A. What a drug does to the body
B. What the body does to a drug
C. The psychological effect of medication
D. The legal process of prescribing
Correct Answer: B
Rationale: Pharmacokinetics describes absorption, distribution, metabolism, and excretion
(ADME). These processes determine the concentration of a drug over time. Pharmacodynamics,
in contrast, describes the effects a drug produces on the body.
Question 2
Which pharmacokinetic process primarily determines how much orally administered medication
reaches systemic circulation?
A. Distribution
B. Bioavailability
C. Protein binding
D. Renal clearance
Correct Answer: B
Rationale: Bioavailability is the fraction of an administered dose that reaches systemic
circulation unchanged. Oral medications may have reduced bioavailability because of incomplete
absorption or first-pass hepatic metabolism.
Question 3
A drug with extensive first-pass metabolism will generally have:
A. Increased oral bioavailability
B. Decreased oral bioavailability
C. Increased renal excretion
D. No hepatic metabolism
Correct Answer: B
Rationale: First-pass metabolism occurs when an orally absorbed drug passes through the
intestinal wall and liver before reaching systemic circulation. Extensive metabolism during this
process can substantially reduce systemic availability.
,Question 4
What does volume of distribution primarily provide information about?
A. Renal filtration rate
B. Extent of drug distribution into tissues
C. Rate of hepatic metabolism
D. Drug absorption from the stomach
Correct Answer: B
Rationale: Volume of distribution (Vd) is a theoretical volume relating the amount of drug in the
body to its plasma concentration. A large Vd generally indicates extensive tissue distribution.
Question 5
A highly protein-bound drug may be affected by a second medication that:
A. Increases gastric emptying
B. Competes for plasma protein binding
C. Decreases urine output
D. Blocks intestinal absorption only
Correct Answer: B
Rationale: Drugs can compete for plasma protein-binding sites. Changes in the unbound fraction
can alter pharmacologic activity and, for some medications, toxicity risk.
Question 6
Which organ is most important for the metabolism of many medications?
A. Liver
B. Spleen
C. Thyroid
D. Pancreas
Correct Answer: A
Rationale: The liver contains numerous metabolic enzymes, including cytochrome P450
enzymes. Hepatic impairment can therefore alter exposure to medications that depend
substantially on hepatic metabolism.
, Question 7
The cytochrome P450 system is particularly important because it:
A. Produces insulin
B. Metabolizes many medications
C. Filters blood through the glomerulus
D. Produces plasma proteins exclusively
Correct Answer: B
Rationale: CYP enzymes participate in phase I metabolism of many drugs. Enzyme inhibition
can increase concentrations of substrate drugs, whereas enzyme induction can decrease their
concentrations.
Question 8
A medication that inhibits CYP3A4 may cause a CYP3A4 substrate to:
A. Reach lower concentrations
B. Be eliminated immediately
C. Reach higher concentrations
D. Become completely inactive
Correct Answer: C
Rationale: Enzyme inhibition reduces metabolism of susceptible substrate drugs. The resulting
increase in drug exposure can increase therapeutic effects and adverse effects.
Question 9
Which patient factor most directly increases concern for accumulation of a predominantly renally
eliminated drug?
A. Increased hair growth
B. Reduced renal function
C. Increased appetite
D. Mild seasonal allergies
Correct Answer: B
