Introduction
This practice examination is designed to prepare BSN students for the HESI 315
Pharmacology examination by emphasizing advanced pharmacologic principles,
clinical judgment, and evidence-based medication management. Questions
integrate pharmacokinetics, pharmacodynamics, therapeutic decision-making,
adverse drug reactions, medication safety, and nursing interventions across multiple
body systems. Learners are expected to apply knowledge to realistic clinical
scenarios similar to those encountered in nursing school examinations and
professional practice. Emphasis is placed on prioritization, patient education,
contraindications, drug interactions, dosage evaluation, and safe administration
principles using current pharmacologic standards for the 2026–2027 academic
cycle.
Question 1
A hospitalized patient receiving IV vancomycin suddenly develops flushing of the
face, neck, and upper torso along with hypotension during infusion. Which nursing
action is most appropriate?
,A. Immediately administer epinephrine IM.
B. Stop the infusion temporarily and restart at a slower rate after notifying the
provider.
C. Continue the infusion because this is an expected therapeutic response.
D. Administer naloxone immediately.
Correct Answer: B
Explanation: Rapid vancomycin infusion may cause Red Man Syndrome, a
histamine-mediated reaction. Slowing the infusion rate usually resolves
symptoms and helps prevent recurrence.
Question 2
A patient taking warfarin begins therapy with trimethoprim-sulfamethoxazole.
Which outcome is the priority concern?
A. Reduced anticoagulant effect
B. Hyperglycemia
C. Increased risk of bleeding
D. Hypertension
Correct Answer: C
Explanation: Trimethoprim-sulfamethoxazole inhibits warfarin metabolism,
significantly increasing INR and the risk of bleeding.
Question 3
A patient with heart failure is prescribed digoxin and furosemide. Which laboratory
finding requires immediate intervention?
A. Sodium 138 mEq/L
B. Potassium 2.9 mEq/L
,C. Calcium 9.2 mg/dL
D. Magnesium 2.0 mg/dL
Correct Answer: B
Explanation: Hypokalemia increases myocardial sensitivity to digoxin and
significantly raises the risk of life-threatening dysrhythmias.
Question 4
A nurse prepares to administer insulin lispro before lunch. The patient's meal is
unexpectedly delayed. What is the safest nursing action?
A. Administer the insulin as scheduled.
B. Hold the insulin until food is available.
C. Double the insulin dose at dinner.
D. Substitute regular insulin.
Correct Answer: B
Explanation: Lispro has a rapid onset. Administering it without immediate food
intake increases the risk of severe hypoglycemia.
Question 5
A patient receiving unfractionated heparin develops hematuria and aPTT of 118
seconds. Which medication should the nurse anticipate?
A. Vitamin K
B. Protamine sulfate
C. Idarucizumab
D. Tranexamic acid
Correct Answer: B
, Explanation: Protamine sulfate is the specific antidote for unfractionated heparin
overdose.
Question 6
A patient taking an ACE inhibitor reports persistent dry cough. Which explanation is
most appropriate?
A. This indicates pulmonary edema.
B. The medication increases bradykinin levels.
C. The patient is developing pneumonia.
D. The medication is ineffective.
Correct Answer: B
Explanation: ACE inhibitors increase bradykinin accumulation, frequently
producing a persistent dry cough.
Question 7
A patient with chronic asthma is prescribed albuterol and fluticasone inhalers.
Which statement demonstrates correct understanding?
A. Use fluticasone during an acute attack.
B. Use albuterol first, then fluticasone several minutes later.
C. Use only one inhaler daily.
D. Use fluticasone before exercise.
Correct Answer: B
Explanation: Bronchodilation from albuterol improves delivery of inhaled
corticosteroids to the lower airways.
