NGN HESI RN Pharmacology Practice Exam 2026 | 4
Full Versions (300+ Questions) with NGN Case
Studies, Answers & Detailed Rationales
Overview
This comprehensive NGN HESI RN Pharmacology Practice Exam (2026 update) is designed
to strengthen clinical judgment, medication safety, and pharmacology mastery for nursing
students preparing for high-stakes exams such as HESI, NCLEX-RN, and advanced nursing
assessments.
The exam set includes 4 full versions with over 300+ high-quality questions, structured from
moderate to extremely difficult levels. Each version progressively builds critical thinking
through NGN-style case scenarios, prioritization questions, multiple-response (SATA), and
medication safety simulations.
You will practice key pharmacology topics including:
Cardiovascular medications (beta-blockers, ACE inhibitors, digoxin, anticoagulants)
Endocrine drugs (insulin, thyroid therapy, corticosteroids)
Antibiotics and infection control therapy
CNS drugs (opioids, benzodiazepines, antidepressants)
Electrolyte and IV medication safety
High-alert medications and toxicity recognition
Each question is designed to simulate real clinical decision-making, helping learners identify:
Priority nursing interventions
Adverse drug reactions and toxicity signs
Medication interactions and contraindications
Patient safety risks and outcomes
The exam emphasizes Next Generation NCLEX (NGN) clinical judgment skills, including
recognizing cues, analyzing data, prioritizing actions, and evaluating outcomes in realistic patient
care situations.
This resource is ideal for nursing students who want:
High-level exam readiness
Strong pharmacology foundation
NGN-style clinical reasoning practice
, Confidence in medication-related decision-making
By completing all four versions, learners gain a structured progression from foundational
knowledge to advanced critical-thinking mastery required for NCLEX success.
Version 1
1. A nurse administers lisinopril to a patient with hypertension and later notes a
persistent dry cough developing over several days. What is the MOST likely
explanation for this adverse effect related to the medication’s mechanism of action?
A. Increased sodium retention
B. Bradykinin accumulation
C. Reduced potassium excretion
D. Increased aldosterone release
✔️ Answer: B. Bradykinin accumulation
Rationale: ACE inhibitors block bradykinin breakdown, leading to cough as a common
adverse effect.
2. A patient receiving furosemide therapy reports muscle cramps, weakness, and
irregular heartbeat. Which electrolyte imbalance should the nurse suspect based on
the pharmacologic action of this loop diuretic?
A. Hyperkalemia
B. Hypokalemia
C. Hypercalcemia
D. Hyponatremia
✔️ Answer: B. Hypokalemia
Rationale: Loop diuretics increase potassium excretion, leading to potentially dangerous
hypokalemia.
3. A nurse prepares to administer insulin glargine to a patient with type 1 diabetes.
What is the MOST important characteristic of this medication that should guide
nursing administration?
A. Rapid onset within minutes
,B. Peak effect within one hour
C. Long-acting with no pronounced peak
D. Short duration requiring frequent dosing
✔️ Answer: C. Long-acting with no pronounced peak
Rationale: Glargine provides steady basal insulin coverage without peaks.
4. A patient taking warfarin is prescribed trimethoprim-sulfamethoxazole for
infection. What is the MOST important nursing consideration regarding this drug
interaction?
A. Decreased anticoagulant effect
B. Increased bleeding risk
C. Reduced antibiotic efficacy
D. Increased clot formation
✔️ Answer: B. Increased bleeding risk
Rationale: Antibiotics can potentiate warfarin, increasing INR and bleeding risk.
5. A nurse assesses a patient receiving morphine for postoperative pain and notes
respiratory rate of 8 breaths per minute. What is the PRIORITY intervention based on
this pharmacologic effect?
A. Document findings
B. Administer naloxone
C. Increase morphine dose
D. Encourage deep breathing
✔️ Answer: B. Administer naloxone
Rationale: Opioid-induced respiratory depression requires immediate reversal.
6. A patient is prescribed metformin and reports gastrointestinal discomfort and
diarrhea during therapy initiation. What is the MOST appropriate nursing response
regarding this common side effect?
A. Discontinue medication immediately
B. Inform patient symptoms often improve with time
, C. Double the dose
D. Take medication on an empty stomach
✔️ Answer: B. Inform patient symptoms often improve with time
Rationale: GI upset is common initially and usually resolves.
7. A nurse is educating a patient taking atorvastatin about potential adverse effects.
Which symptom should the patient report immediately due to risk of a serious
complication?
A. Mild headache
B. Muscle pain or weakness
C. Increased appetite
D. Dry mouth
✔️ Answer: B. Muscle pain or weakness
Rationale: May indicate rhabdomyolysis, a serious adverse effect.
8. A patient receiving heparin therapy develops sudden onset of bleeding and
bruising. Which laboratory value should the nurse monitor to evaluate therapeutic
effect and safety?
A. INR
B. aPTT
C. Hemoglobin only
D. Platelet count only
✔️ Answer: B. aPTT
Rationale: aPTT monitors heparin effectiveness and bleeding risk.
9. A nurse administers albuterol via inhaler for acute bronchospasm. Which
assessment finding indicates the medication is achieving its intended therapeutic
effect?
A. Increased mucus production
B. Improved airflow and decreased wheezing
C. Decreased respiratory rate only
D. Increased coughing
