1. A patient receives an oral drug that is rapidly absorbed from the small intestine. Which
pharmacokinetic process determines movement from the gastrointestinal tract into the bloodstream?
A) Distribution
B) Metabolism
C) Absorption
D) Excretion
Correct Answer: Absorption
Rationale: Absorption is the movement of a drug from its site of administration into systemic circulation.
Distribution occurs after the drug reaches blood, metabolism chemically alters the drug, and excretion removes
drug or metabolites from the body.
2. Two patients receive the same oral dose, but one has extensive first-pass hepatic metabolism.
What is most likely reduced in that patient?
A) Bioavailability
B) Receptor affinity
C) Renal clearance
D) Protein synthesis
Correct Answer: Bioavailability
Rationale: First-pass metabolism can remove a substantial fraction of an orally administered dose before it
reaches systemic circulation, reducing bioavailability. It does not directly determine receptor affinity or protein
synthesis, and renal clearance occurs after systemic exposure.
3. A medication is highly bound to albumin. Which fraction is most immediately available to cross
membranes and bind receptors?
A) The albumin-bound fraction
B) The unbound fraction
C) The conjugated fraction
D) The biliary fraction
Correct Answer: The unbound fraction
Rationale: Only unbound drug is freely diffusible and immediately available for receptor binding, metabolism, and
filtration. Protein-bound drug acts as a reservoir and must dissociate before it can exert pharmacologic effects.
4. An older adult has reduced serum albumin and takes a highly protein-bound medication. What
change is most likely?
A) A lower free-drug concentration
, B) Complete loss of absorption
C) A higher free-drug concentration
D) Immediate enzyme induction
Correct Answer: A higher free-drug concentration
Rationale: Lower albumin provides fewer binding sites, increasing the proportion of unbound drug. That can
increase pharmacologic and toxic effects even when the measured total drug concentration appears unchanged.
5. A lipophilic medication crosses the blood-brain barrier more readily than a hydrophilic drug
primarily because it can do what?
A) Bind irreversibly to albumin
B) Avoid all hepatic metabolism
C) Increase glomerular filtration
D) Dissolve in endothelial cell membranes
Correct Answer: Dissolve in endothelial cell membranes
Rationale: The blood-brain barrier favors lipid-soluble molecules that can diffuse through endothelial cell
membranes. Albumin binding generally limits distribution, and hepatic metabolism or filtration does not explain
membrane passage into the CNS.
6. A drug is described as having a large apparent volume of distribution. What does that usually
suggest?
A) Confinement mainly to plasma
B) No protein binding
C) Rapid renal excretion only
D) Extensive distribution into tissues
Correct Answer: Extensive distribution into tissues
Rationale: A large apparent volume of distribution usually indicates that much of the drug has left the plasma and
distributed into tissues. Drugs largely confined to plasma generally have smaller apparent volumes of distribution.
7. A drug has a half-life of 8 hours. About how long is usually required to approach steady state
during repeated dosing?
A) About 32-40 hours
B) About 8 hours
C) About 16 hours
D) About 80-96 hours
Correct Answer: About 32-40 hours
Rationale: Most drugs approach steady state after roughly four to five half-lives. With an 8-hour half-life, that is
approximately 32 to 40 hours, assuming linear kinetics and no loading dose.
8. Which change would most likely increase the elimination half-life of a renally cleared drug?
A) Increased renal clearance
