QUESTIONS & ANSWERS
NURS 5663 Pharm Weekly Quizzes | Week 1–6 | Question Practice Exam
1. Which of the following best describes pharmacokinetics?
A) What the drug does to the body
B) What the body does to the drug
C) The clinical indication for a medication
D) The toxicity caused by a medication
Correct Answer: B) What the body does to the drug
Rationale: Pharmacokinetics describes the movement of a drug through the body,
summarized as absorption, distribution, metabolism, and excretion (ADME).
Pharmacodynamics describes the effects a drug produces in the body.
2. What are the four primary phases of pharmacokinetics?
A) Absorption, Distribution, Metabolism, Excretion
B) Agonism, Antagonism, Potentiation, Inhibition
C) Uptake, Binding, Signaling, Clearance
D) Ingestion, Transport, Breakdown, Elimination
Correct Answer: A) Absorption, Distribution, Metabolism, Excretion
Rationale: Pharmacokinetics describes what the body does to a drug across four
sequential phases: absorption, distribution, metabolism, and excretion.
3. Which process describes movement of a drug from its site of administration into
systemic circulation?
A) Distribution
B) Metabolism
, Page 2 of 29
C) Absorption
D) Excretion
Correct Answer: C) Absorption
Rationale: Absorption is the movement of a drug from the administration site into the
bloodstream. Route of administration, formulation, gastrointestinal function, blood
flow, and drug properties all affect absorption.
4. Which route of administration generally provides the most complete and
immediate systemic bioavailability?
A) Oral
B) Intramuscular
C) Subcutaneous
D) Intravenous
Correct Answer: D) Intravenous
Rationale: Intravenous administration places the drug directly into systemic
circulation, resulting in essentially 100% bioavailability. Oral and other extravascular
routes require absorption before reaching systemic circulation.
5. What is bioavailability?
A) The amount of drug bound to protein
B) The fraction of an administered dose that reaches systemic circulation unchanged
C) The rate at which a drug is eliminated
D) The amount of drug stored in adipose tissue
Correct Answer: B) The fraction of an administered dose that reaches systemic
circulation unchanged
Rationale: Bioavailability refers to the fraction of an administered dose that reaches
systemic circulation in an active or unchanged form. Intravenous medications have
essentially complete bioavailability.
6. Which organ is primarily responsible for drug metabolism?
A) Heart
B) Liver
C) Spleen
D) Pancreas
, Page 3 of 29
Correct Answer: B) Liver
Rationale: The liver is the principal organ responsible for drug metabolism. Hepatic
enzymes, particularly cytochrome P450 enzymes, participate in the metabolism of
many medications.
7. A provider prescribes an oral medication with a substantial first-pass effect.
What is the clinical implication?
A) The drug will achieve higher bioavailability than IV administration
B) A significant fraction is metabolized by liver enzymes before reaching systemic
circulation
C) The drug will bypass the liver entirely via the lymphatic system
D) Protein binding will be negligible
Correct Answer: B) A significant fraction is metabolized by liver enzymes before
reaching systemic circulation
Rationale: Orally administered drugs enter portal circulation and pass through the liver
before reaching systemic targets. High first-pass metabolism lowers oral bioavailability.
8. Which of the following statements best describes the first-pass metabolism
effect?
A) The breakdown of a drug in the stomach before absorption
B) The hepatic inactivation of orally ingested drugs before systemic circulation
C) The accumulation of a drug in body fat over time
D) The renal excretion of unchanged drug
Correct Answer: B) The hepatic inactivation of orally ingested drugs before
systemic circulation
Rationale: First-pass metabolism occurs when an orally ingested drug is absorbed from
the GI tract and travels via the portal circulation directly to the liver, where it may be
significantly metabolized before reaching systemic circulation.
9. How do lipid-soluble drugs behave differently from water-soluble drugs
regarding tissue distribution?
A) Lipid-soluble drugs cannot cross the blood-brain barrier
B) Lipid-soluble drugs readily cross cellular membranes, including the BBB and
placenta
C) Water-soluble drugs distribute more widely into adipose tissue
D) Water-soluble drugs require active transport for all cellular uptake
