INTRODUCTION
This comprehensive assessment is designed to strengthen the knowledge, clinical reasoning,
and medication-safety skills required for nursing pharmacology examinations. The questions
assess foundational concepts, drug classifications, mechanisms of action, adverse effects,
contraindications, interactions, monitoring parameters, administration principles, and
appropriate nursing interventions. Multiple-choice questions emphasize both recognition and
application of pharmacologic knowledge. Several items require interpretation of patient
findings and prioritization of nursing actions. Understanding why a medication is
administered, how it works, what complications may occur, and how the nurse evaluates
therapeutic response is essential for safe practice and effective examination preparation.
SECTION ONE: QUESTIONS 1–100
Question 1. Which pharmacokinetic process describes the movement of a medication from
the site of administration into the systemic circulation?
A. Distribution
B. Absorption
C. Metabolism
D. Excretion
Correct Answer: B. Absorption
,Explanation: Absorption is the process by which a medication moves from its administration
site into the bloodstream. Distribution occurs after the drug enters circulation, metabolism
chemically alters the drug, and excretion removes the drug from the body.
Question 2. A nurse explains that the liver is primarily responsible for which pharmacokinetic
process?
A. Absorption
B. Distribution
C. Metabolism
D. Receptor binding
Correct Answer: C. Metabolism
Explanation: The liver is the major organ responsible for drug metabolism. Hepatic enzymes,
particularly the cytochrome P450 system, transform many medications into metabolites that
may be active, inactive, or easier to eliminate.
Question 3. Which route of medication administration generally provides the most rapid
systemic effect?
A. Intravenous
B. Oral
C. Subcutaneous
D. Intramuscular
Correct Answer: A. Intravenous
Explanation: Intravenous administration places the medication directly into the
bloodstream, producing essentially immediate systemic availability. Oral, subcutaneous, and
intramuscular routes require additional absorption before the medication reaches systemic
circulation.
Question 4. A medication has a half-life of 8 hours. Approximately how much of the
medication remains in the body 16 hours after administration?
A. 75%
B. 50%
C. 25%
D. 12.5%
Correct Answer: C. 25%
Explanation: After one half-life, 50% remains. After two half-lives, 25% remains. Therefore,
16 hours represents two 8-hour half-lives, leaving approximately one-fourth of the original
amount.
, Question 5. Which finding most strongly suggests that a patient is experiencing an adverse
drug reaction rather than the intended therapeutic effect?
A. Decreased blood pressure after an antihypertensive
B. Reduced pain after an analgesic
C. Improved blood glucose after insulin
D. Wheezing and facial swelling after a new medication
Correct Answer: D. Wheezing and facial swelling after a new medication
Explanation: Wheezing and facial swelling can indicate a serious hypersensitivity or
anaphylactic reaction. The other findings represent expected therapeutic responses to the
medications described.
Question 6. A patient is prescribed a medication with a narrow therapeutic index. What is
the nurse's priority?
A. Administer the medication without laboratory monitoring
B. Monitor for therapeutic and toxic effects closely
C. Encourage the patient to double the dose if symptoms persist
D. Give the medication only when symptoms become severe
Correct Answer: B. Monitor for therapeutic and toxic effects closely
Explanation: Drugs with a narrow therapeutic index have a small difference between
effective and toxic concentrations. Close assessment and appropriate laboratory monitoring
are therefore essential.
Question 7. Which statement best describes a medication's therapeutic effect?
A. The predictable desired response produced by the medication
B. An unexpected immune-mediated response
C. A toxic response caused by medication accumulation
D. A harmful response occurring only after an overdose
Correct Answer: A. The predictable desired response produced by the medication
Explanation: The therapeutic effect is the intended clinical response for which the
medication is prescribed. Adverse effects, toxicity, and allergic reactions are different
concepts.
Question 8. A nurse is preparing to administer a medication. Which action best reduces the
risk of a medication error?
A. Relying on memory for frequently administered drugs
B. Comparing the medication label with the medication record at required verification points
C. Asking another patient whether the medication looks familiar
D. Preparing medications for several patients simultaneously
