Introduction
The Relias RN Pharmacology examination is designed to assess the clinical competence of registered nurses in safe
medication administration and pharmacologic principles. It evaluates candidates' ability to apply pharmacokinetic and
pharmacodynamic concepts, identify adverse drug effects, perform accurate dosage calculations, and make evidence-
based clinical decisions. The exam employs multiple-choice and scenario-based questions that require critical thinking
and real-world application rather than simple memorization. Emphasis is placed on medication safety, regulatory
,compliance, ethical professional standards, and the nurse's role in monitoring therapeutic responses and preventing
medication errors across diverse patient populations.
SECTION ONE: QUESTIONS 1–50
Question 1
A nurse is reviewing the pharmacokinetic properties of a newly prescribed medication. Which process describes the
movement of a drug from its site of administration into the systemic circulation?
A. Distribution
B. Metabolism
C. Absorption
D. Excretion
🟢 Correct Answer: C. Absorption
🔴 Explanation: Absorption is the pharmacokinetic process by which a drug moves from its administration site into
the bloodstream. Distribution follows absorption and involves transport to tissues. Metabolism refers to
,biotransformation, primarily in the liver. Excretion is the elimination of drug metabolites from the body.
Question 2
A patient with a history of heart failure is prescribed furosemide. Which laboratory value requires the most
immediate attention?
A. Serum sodium of 138 mEq/L
B. Serum potassium of 2.8 mEq/L
C. Serum creatinine of 1.0 mg/dL
D. Hemoglobin of 13.5 g/dL
🟢 Correct Answer: B. Serum potassium of 2.8 mEq/L
🔴 Explanation: Furosemide is a loop diuretic that promotes potassium excretion, placing patients at significant risk
for hypokalemia. A potassium level of 2.8 mEq/L is critically low and can precipitate cardiac dysrhythmias. Other
values listed are within acceptable ranges.
Question 3
, A nurse is administering IV vancomycin to a patient with MRSA infection. Thirty minutes into the infusion, the
patient develops flushing, erythema, and pruritus on the face and neck. Blood pressure remains stable. What is the
nurse's priority action?
A. Stop the infusion and administer epinephrine
B. Slow the infusion rate and continue monitoring
C. Document the finding as an allergic reaction
D. Increase the infusion rate to complete therapy faster
🟢 Correct Answer: B. Slow the infusion rate and continue monitoring
🔴 Explanation: The patient is experiencing Red Man Syndrome, a histamine-mediated reaction caused by rapid
vancomycin infusion. It is not a true allergic reaction. The appropriate intervention is to slow the infusion rate and
monitor the patient. Epinephrine is reserved for anaphylaxis.
Question 4
A patient taking warfarin for atrial fibrillation asks which over-the-counter pain reliever is safest. Which response by
the nurse is most appropriate?
