Complete Exam Prep Pack –
Study Guide + Questions &
Answers (2026)
1. What is the primary goal of pharmacology in
advanced nursing practice?
A. To diagnose diseases
B. To understand how drugs affect the body and
how the body affects drugs
C. To perform surgical procedures
D. To replace physician roles
Correct Answer: B
Rationale: Pharmacology focuses on drug actions,
mechanisms, and interactions within the body to
ensure safe and effective therapy.
2. What is pharmacokinetics?
A. What the drug does to the body
B. How the body absorbs, distributes, metabolizes,
and excretes a drug
C. Drug manufacturing process
D. Drug storage methods
,Correct Answer: B
Rationale: Pharmacokinetics describes the
movement of drugs through the body (ADME
process).
3. What is pharmacodynamics?
A. How the body processes a drug
B. Drug side effects only
C. What the drug does to the body
D. Drug pricing systems
Correct Answer: C
Rationale: Pharmacodynamics refers to the
biological and physiological effects of drugs and
their mechanisms of action.
4. What does “absorption” mean in
pharmacokinetics?
A. Drug breakdown in the liver
B. Movement of drug into bloodstream
C. Drug elimination from kidneys
D. Drug binding to receptors
Correct Answer: B
Rationale: Absorption is the process by which a
drug enters systemic circulation.
,5. Which route of administration has the fastest
onset of action?
A. Oral
B. Intramuscular
C. Intravenous
D. Subcutaneous
Correct Answer: C
Rationale: IV administration delivers drugs directly
into the bloodstream, producing immediate effects.
6. What is first-pass metabolism?
A. Drug excretion through urine
B. Drug metabolism in the kidneys
C. Drug breakdown in the liver before reaching
systemic circulation
D. Drug absorption in the stomach
Correct Answer: C
Rationale: Oral drugs are metabolized in the liver
before reaching systemic circulation, reducing
bioavailability.
7. What is bioavailability?
A. Amount of drug excreted
B. Fraction of drug that reaches systemic circulation
unchanged
C. Drug toxicity level
, D. Drug cost effectiveness
Correct Answer: B
Rationale: Bioavailability refers to how much of the
administered drug reaches circulation in active form.
8. What does “distribution” refer to?
A. Drug movement from bloodstream into tissues
B. Drug breakdown in the liver
C. Drug elimination via urine
D. Drug manufacturing
Correct Answer: A
Rationale: Distribution describes how drugs spread
through body fluids and tissues.
9. What factor affects drug distribution?
A. Hair color
B. Protein binding in plasma
C. Eye color
D. Blood type only
Correct Answer: B
Rationale: Drugs bound to plasma proteins are
inactive and affect distribution levels.
10. What is drug metabolism primarily
responsible for?
A. Drug absorption
