This comprehensive exam assesses critical pharmacology knowledge essential for nursing practice and NCLEX-RN preparation. The purpose is to
evaluate a candidate's mastery of drug classes, mechanisms of action, adverse effects, medication safety protocols, and clinical decision-making
skills in real-world healthcare scenarios. The assessment features 100 multiple-choice questions with scenario-based items that emphasize applied
professional knowledge rather than simple recall. Candidates will encounter questions covering foundational theory, regulatory compliance,
ethics, and professional standards. The exam prioritizes real-world application, requiring nurses to demonstrate critical thinking when selecting
medications, monitoring for adverse effects, preventing errors, and educating patients about pharmacotherapy. Success on this assessment
indicates readiness for safe, effective medication administration in clinical practice.
Section One: Questions 1–100
Question 1
A nurse is administering digoxin to a patient with heart failure. The patient's serum digoxin level is 2.4 ng/mL. What is the nurse's priority action?
A. Administer the next dose as scheduled
B. Notify the healthcare provider immediately
C. Document the finding and continue monitoring
D. Give potassium supplement before next dose
🟢 Correct answer: B
,🔴 RATIONALE: Normal digoxin therapeutic range is 0.5-2.0 ng/mL. A level of 2.4 ng/mL indicates digoxin toxicity, which requires immediate
provider notification to prevent life-threatening complications such as severe arrhythmias. Continuing administration or only documenting would be
unsafe.
Question 2
Which medication class should the nurse avoid administering to a patient with COPD?
A. Beta-2 agonists
B. Non-selective beta-blockers
C. Anticholinergics
D. Corticosteroids
🟢 Correct answer: B
🔴 RATIONALE: Non-selective beta-blockers block both beta-1 and beta-2 receptors, causing bronchoconstriction by inhibiting beta-2 mediated
bronchodilation. This can worsen COPD symptoms. Beta-2 agonists, anticholinergics, and corticosteroids are commonly used to treat COPD.
Question 3
A patient receiving warfarin therapy has a PT of 35 seconds and INR of 4.2. What is the nurse's appropriate action?
A. Administer the next warfarin dose
B. Give vitamin K immediately
C. Hold warfarin and notify provider
D. Increase warfarin dose by 1 mg
🟢 Correct answer: C
🔴 RATIONALE: Normal INR for warfarin therapy is 2.0-3.0 (or 2.5-3.5 for high-risk patients). An INR of 4.2 is supratherapeutic, indicating
increased bleeding risk. The nurse should hold warfarin and notify the provider for dose adjustment. Vitamin K is given for more severe elevations or
active bleeding.
Question 4
Which drug is the priority treatment for a patient experiencing acute magnesium sulfate toxicity?
,A. Calcium gluconate
B. Sodium bicarbonate
C. Potassium chloride
D. Protamine sulfate
🟢 Correct answer: A
🔴 RATIONALE: Calcium gluconate is the antidote for magnesium sulfate toxicity. It counteracts magnesium's effects on cardiac conduction and
neuromuscular function. The other options are not appropriate for magnesium toxicity.
Question 5
A patient on lithium carbonate reports tremors, confusion, and diarrhea. What is the nurse's first action?
A. Encourage increased fluid intake
B. Obtain a lithium level immediately
C. Administer PRN antiemetic
D. Document as expected side effects
🟢 Correct answer: B
🔴 RATIONALE: These symptoms indicate lithium toxicity (therapeutic range 0.6-1.2 mEq/L). Immediate lithium level assessment is critical to
confirm toxicity and guide treatment. Increased fluids may be indicated later but assessment is priority. These are not expected side effects.
Question 6
Which medication requires monitoring of renal function due to risk of acute kidney injury?
A. Amoxicillin
B. Vancomycin
C. Levothyroxine
D. Metoprolol
🟢 Correct answer: B
, 🔴 RATIONALE: Vancomycin is associated with nephrotoxicity, especially with high doses, prolonged therapy, or concurrent use of other
nephrotoxic drugs. Serial renal function monitoring (BUN, creatinine) is essential. Amoxicillin, levothyroxine, and metoprolol have lower
nephrotoxicity risk.
Question 7
A patient with Type 2 diabetes is prescribed metformin. Which condition requires the nurse to hold metformin and contact the provider?
A. Blood glucose of 180 mg/dL
B. Serum creatinine of 1.6 mg/dL
C. Mild nausea after administration
D. Heart rate of 72 bpm
🟢 Correct answer: B
🔴 RATIONALE: Metformin is contraindicated in renal impairment (creatinine >1.5 mg/dL in men, >1.4 mg/dL in women) due to risk of lactic
acidosis. Elevated creatinine indicates renal dysfunction requiring dose adjustment or discontinuation. Nausea is a common side effect; other values
are not concerning.
Question 8
Which antihypertensive medication can cause hyperkalemia and requires potassium monitoring?
A. Hydrochlorothiazide
B. Lisinopril
C. Furosemide
D. Amlodipine
🟢 Correct answer: B
🔴 RATIONALE: Lisinopril is an ACE inhibitor that reduces aldosterone secretion, leading to potassium retention and potential hyperkalemia. Serial
potassium monitoring is essential. Hydrochlorothiazide and furosemide cause hypokalemia; amlodipine does significantly affect potassium.
Question 9
A patient receiving morphine sulfate for pain has a respiratory rate of 8/min. What is the nurse's priority intervention?
