UPDATE ALREADY GRADED A+
This comprehensive question bank contains 300 unique, Next Generation NCLEX
(NGN) style multiple-choice questions specifically designed for the HESI RN
Pharmacology Proctored Exit Exam. The questions are organized into 30 sections

endocrine, neurological, anti-infective, gastrointestinal, psychiatric, and emergency
medications. Each question includes a correct answer and a detailed rationale
explaining the clinical reasoning and medication-specific nursing interventions.
This resource is ideal for self-assessment, targeted review, and exam preparation,
helping students identify knowledge gaps and reinforce understanding of
pharmacology concepts for licensure readiness. Use this bank systematically to
build confidence and achieve success on the HESI exit exam.
Section 1: Cardiovascular Medications
Question 1: A client receiving digoxin (Lanoxin) therapy reports nausea, vomiting,
and visual disturbances. Which lab value should the nurse check first?
A) Serum potassium level
B) Serum digoxin level
C) BUN and creatinine
D) Serum magnesium level
Answer: B) Serum digoxin level
Rationale: Nausea, vomiting, and visual disturbances are classic signs of digoxin
toxicity. The priority action is to check the serum digoxin level to confirm toxicity.
While potassium, renal function, and magnesium are also important (hypokalemia
and renal impairment increase toxicity risk), the digoxin level is the direct indicator
of toxicity and should be checked first.
,Question 2: A client is prescribed sublingual nitroglycerin for angina. Which
assessment finding indicates the medication was effective?
A) Decrease in chest pain
B) Increase in blood pressure
C) Decrease in heart rate
D) Increase in respiratory rate
Answer: A) Decrease in chest pain
Rationale: Nitroglycerin is a vasodilator that relieves angina by reducing preload
and afterload, decreasing myocardial oxygen demand. The therapeutic goal is relief
of chest pain within 3-5 minutes. A decrease in chest pain is the primary indicator
of effectiveness. Nitroglycerin typically causes decreased blood pressure and reflex
tachycardia, not an increase in BP or decrease in HR.
Question 3: A client receiving intravenous heparin therapy has a partial
thromboplastin time (PTT) of 120 seconds. What is the nurse's priority action?
A) Continue the infusion as ordered
B) Decrease the infusion rate
C) Stop the infusion and notify the provider
D) Administer protamine sulfate
Answer: C) Stop the infusion and notify the provider
Rationale: The therapeutic PTT for heparin is typically 1.5 to 2.5 times the normal
control (approximately 60-100 seconds). A PTT of 120 seconds indicates excessive
anticoagulation and significant bleeding risk. The nurse should stop the infusion
and notify the healthcare provider immediately. Protamine sulfate is the antidote
but is administered based on provider order after assessing the clinical situation.
Question 4: A client is prescribed warfarin (Coumadin) for atrial fibrillation.
Which laboratory value indicates therapeutic effectiveness?
A) INR of 2.5
B) PTT of 45 seconds
C) Platelet count of 250,000
D) Hemoglobin of 14 g/dL
Answer: A) INR of 2.5
,Rationale: For warfarin therapy, the therapeutic INR range for atrial fibrillation is
typically 2.0 to 3.0. An INR of 2.5 is within this therapeutic range. PTT monitors
heparin therapy, not warfarin. Platelet count and hemoglobin are monitored for
bleeding complications but do not indicate therapeutic effectiveness of warfarin.
Question 5: A client is prescribed enoxaparin (Lovenox) 30 mg/0.3 mL IV every
12 hours following hip replacement surgery. What is the nurse's priority
intervention?
A) Administer the medication as prescribed
B) Contact the provider to clarify the prescription
C) Administer the medication subcutaneously
D) Check the client's platelet count
Answer: B) Contact the provider to clarify the prescription
Rationale: Enoxaparin is a low-molecular-weight heparin that is administered
subcutaneously, not intravenously. The IV route for this medication is incorrect
and potentially dangerous. The nurse should contact the provider to clarify the
route of administration. Subcutaneous injection is the correct route for enoxaparin.
Question 6: A client on amiodarone therapy develops pulmonary symptoms
including cough and dyspnea. What is the nurse's priority action?
A) Administer a bronchodilator
B) Obtain a chest x-ray
C) Notify the provider immediately
D) Increase oxygen flow rate
Answer: C) Notify the provider immediately
Rationale: Amiodarone is associated with potentially fatal pulmonary toxicity
(pulmonary fibrosis). New onset cough, dyspnea, and other pulmonary symptoms
require immediate provider notification for evaluation and possible discontinuation
of the drug. While oxygen and diagnostic tests may be needed, the priority is
reporting the adverse effect.
Question 7: A client prescribed clopidogrel (Plavix) following stent placement asks
why they cannot take omeprazole for heartburn. What is the nurse's best response?
A) Omeprazole decreases the effectiveness of clopidogrel
B) Omeprazole increases bleeding risk with clopidogrel
C) Omeprazole interacts with the same liver enzymes
, D) There is no interaction; you can take both
Answer: A) Omeprazole decreases the effectiveness of clopidogrel
Rationale: Omeprazole and other proton pump inhibitors (PPIs) interfere with the
activation of clopidogrel by competing for the CYP2C19 liver enzyme. This
reduces clopidogrel's antiplatelet effectiveness, increasing the risk of stent
thrombosis. Alternative acid-reducing medications such as H2 blockers (ranitidine,
famotidine) are preferred.
Question 8: A client on furosemide (Lasix) for heart failure is prescribed a
potassium supplement. Which finding indicates the medication is working
effectively?
A) Serum potassium of 3.8 mEq/L
B) Weight loss of 2 pounds in 3 days
C) Blood pressure of 140/90
D) Serum sodium of 135 mEq/L
Answer: B) Weight loss of 2 pounds in 3 days
Rationale: Furosemide is a loop diuretic used to reduce fluid volume in heart
failure. A weight loss of 1-2 pounds per day indicates effective diuresis. While
potassium supplementation helps maintain normal potassium levels, the primary
therapeutic goal is fluid reduction to decrease cardiac workload.
Question 9: A client receiving an IV infusion of dopamine experiences
extravasation. What is the nurse's priority action?
A) Apply a warm compress to the site
B) Administer phentolamine (Regitine) locally
C) Stop the infusion immediately
D) Elevate the affected extremity
Answer: C) Stop the infusion immediately
Rationale: Dopamine is a vasopressor that can cause severe tissue necrosis if
extravasation occurs. The priority action is to stop the infusion immediately to
prevent further tissue damage. Phentolamine is the antidote used for extravasation
but should be administered after stopping the infusion, based on provider order.
