Introduction
This comprehensive examination is designed to assess the
advanced pharmacological knowledge and clinical decision-
making skills of baccalaureate nursing students preparing for the
HESI Pharmacology II specialty exam. The assessment evaluates
proficiency in pharmacokinetics, pharmacodynamics, drug
classifications, adverse effect recognition, patient safety
protocols, and therapeutic monitoring across the lifespan. The
multiple-choice and scenario-based questions emphasize real-
world application, critical thinking, and safe medication
administration practices essential for professional nursing
practice. Content aligns with the NCLEX-RN Pharmacological and
Parenteral Therapies domain and the HESI Pharmacology
blueprint, ensuring rigorous preparation for contemporary clinical
challenges.
SECTION ONE: QUESTIONS 1–100
1. A client is prescribed a medication with a half-life of 4
days. Based on this half-life, the medication will most
likely be prescribed:
A. Once a day
B. Twice a day
C. Three times a day
D. Four times a day
A. Once a day
, RATIONALE: Medications with long half-lives remain at
therapeutic levels between doses for extended periods, allowing
for once-daily dosing. A half-life of 4 days means the drug stays
in the body long enough that frequent dosing is unnecessary.
2. A client taking lisinopril reports swelling of the lips and
difficulty breathing. What is the nurse's priority action?
A. Administer the next dose with food
B. Hold the medication and notify the healthcare provider
immediately
C. Encourage increased fluid intake
D. Place the client in a supine position
B. Hold the medication and notify the healthcare provider
immediately
RATIONALE: Facial or lip swelling with breathing difficulty
suggests angioedema, a potentially life-threatening adverse
reaction associated with ACE inhibitors. The medication should be
withheld and emergency treatment initiated.
3. A patient is prescribed digoxin for heart failure. What is
the primary mechanism of action of digoxin?
A. Increases heart rate
B. Inhibits the sodium-potassium ATPase pump
C. Promotes vasodilation
D. Decreases contractility
B. Inhibits the sodium-potassium ATPase pump
RATIONALE: Digoxin inhibits the Na+/K+ ATPase pump,
increasing intracellular calcium and enhancing myocardial
, contractility. This positive inotropic effect improves cardiac output
in heart failure.
4. A nurse is administering a medication with a half-life of
4 hours. If the initial dose is 400 mg, what is the
approximate amount remaining after 8 hours?
A. 100 mg
B. 200 mg
C. 300 mg
D. 400 mg
A. 100 mg
RATIONALE: After 8 hours (2 half-lives): 400 mg → 200 mg (4
hrs) → 100 mg (8 hrs). Each half-life reduces the remaining drug
concentration by 50%.
5. A patient is taking warfarin. What is the primary
therapeutic effect of warfarin?
A. Increases platelet aggregation
B. Inhibits vitamin K-dependent clotting factors
C. Enhances fibrinolysis
D. Decreases prothrombin time
B. Inhibits vitamin K-dependent clotting factors
RATIONALE: Warfarin blocks factors II, VII, IX, and X,
prolonging PT/INR. This anticoagulant effect prevents clot
formation in conditions such as atrial fibrillation and venous
thromboembolism.
6. What is the primary route of elimination for most water-
soluble drugs?
