, Gastrointestinal, Renal, and Respiratory Medications
The BSN HESI 315 Pharmacology Examination assesses nursing students' comprehensive knowledge of
pharmacological principles, drug classifications, nursing implications, and medication safety. This rigorous
examination evaluates understanding of pharmacokinetics, pharmacodynamics, therapeutic effects, adverse
reactions, and drug interactions across major medication categories. Students must demonstrate clinical reasoning
through scenario-based questions requiring application of the nursing process to medication administration,
including dosage calculations, monitoring parameters, and patient education. The examination emphasizes safe
medication administration, recognizing adverse effects, and making evidence-based decisions in medication
management. Successful completion verifies competency in pharmacological knowledge essential for safe, quality
nursing practice and preparation for the NCLEX-RN licensure examination.
SECTION ONE: QUESTIONS 1–100
Question 1
A patient is prescribed furosemide (Lasix) 40 mg orally daily. The nurse should expect this medication to exert
its therapeutic effect by acting on which site?
,A. Proximal convoluted tubule
B. Loop of Henle
C. Distal convoluted tubule
D. Collecting duct
🟢 Correct Answer: B
🔴 RATIONALE: Furosemide is a loop diuretic that inhibits sodium and chloride reabsorption in the ascending
loop of Henle . This leads to significant diuresis and is used to manage edema and hypertension. The resulting
electrolyte losses can cause hypokalemia and hyponatremia.
Question 2
A patient with heart failure is prescribed digoxin. Which laboratory value should the nurse monitor closely to
prevent digoxin toxicity?
A. Serum potassium
B. Serum sodium
C. Serum calcium
D. Serum magnesium
🟢 Correct Answer: A
🔴 RATIONALE: Hypokalemia increases the risk of digoxin toxicity . Potassium levels should be monitored and
maintained within normal range (3.5-5.0 mEq/L). Digoxin toxicity can cause nausea, vomiting, visual
, disturbances (yellow-green halos), and cardiac arrhythmias.
Question 3
A patient prescribed warfarin has an international normalized ratio (INR) of 5.5 without signs of bleeding. The
nurse should anticipate which intervention?
A. Holding the warfarin dose and monitoring the INR
B. Administering vitamin K 10 mg IV
C. Administering protamine sulfate
D. Increasing the warfarin dose
🟢 Correct Answer: A
🔴 RATIONALE: An INR of 5.5 without bleeding indicates supratherapeutic anticoagulation. The nurse should
hold the dose, monitor the INR, and notify the provider . Vitamin K (phytonadione) is indicated for bleeding or
very high INR (>10). Protamine sulfate is the antidote for heparin.
Question 4
A patient receiving heparin IV for a pulmonary embolism has an aPTT of 110 seconds (normal 25-35 seconds).
The nurse should anticipate which intervention?
