Introduction
*This comprehensive assessment evaluates mastery of ATI Pharmacology principles essential for safe and
effective nursing practice. It measures foundational drug knowledge, clinical reasoning in medication
management, adherence to legal and ethical standards, and the ability to apply pharmacological concepts in
real-world patient scenarios. The exam comprises 200 multiple-choice questions divided into two sections,
emphasizing critical thinking, prioritization, and decision-making required for the NCLEX and clinical settings.
,Each question includes a verified correct answer and a concise rationale. All content reflects current evidence-
based guidelines and professional standards.*
SECTION ONE: QUESTIONS 1–100
Question 1
A nurse administers digoxin to a client with heart failure. Which finding requires immediate intervention?
A. Apical pulse of 62 beats per minute
B. Serum digoxin level of 1.2 ng/mL
C. Client reports nausea and yellow vision
D. Blood pressure of 118/76 mm Hg
🟢C
🔴 RATIONALE: Nausea and yellow (or blurred) vision are classic signs of digoxin toxicity. An apical pulse of 62
is within safe range (hold if <60). A level of 1.2 ng/mL is therapeutic (0.8–2.0 ng/mL). BP is normal.
Question 2
A client prescribed warfarin has an INR of 3.8. What action should the nurse take?
A. Administer vitamin K as ordered
B. Increase the warfarin dose
C. Hold the next dose and notify the provider
D. Recheck INR in one week
,🟢C
🔴 RATIONALE: Therapeutic INR for most conditions is 2.0–3.0. An INR of 3.8 is elevated but not critically high
unless >4.5. Holding the dose and notifying the provider is appropriate. Vitamin K is reserved for active
bleeding or extreme elevations.
Question 3
Which medication is contraindicated in a client with severe asthma?
A. Albuterol
B. Propranolol
C. Prednisone
D. Montelukast
🟢B
🔴 RATIONALE: Propranolol is a nonselective beta-blocker that can cause bronchospasm by blocking beta-2
receptors in the lungs. Albuterol (beta-agonist), prednisone (steroid), and montelukast (leukotriene inhibitor)
are used to treat asthma.
Question 4
A nurse is teaching a client about sublingual nitroglycerin. Which statement indicates understanding?
A. “I can take up to five tablets every 15 minutes.”
B. “I will swallow the tablet with a full glass of water.”
C. “I should take one tablet every 5 minutes for up to three doses.”
D. “I will store the tablets in a clear plastic bottle.”
, 🟢C
🔴 RATIONALE: Standard dosing for sublingual nitroglycerin is one tablet every 5 minutes for up to three doses
for chest pain. Tablets are placed under the tongue, not swallowed. Store in original dark glass container to
protect from light and moisture.
Question 5
A client receives morphine sulfate 4 mg IV push. Fifteen minutes later, the respiratory rate is 8 breaths/minute.
Which medication should the nurse anticipate administering?
A. Naloxone
B. Flumazenil
C. Acetylcysteine
D. Activated charcoal
🟢A
🔴 RATIONALE: Naloxone is an opioid antagonist that reverses respiratory depression caused by morphine.
Flumazenil reverses benzodiazepines. Acetylcysteine treats acetaminophen overdose. Activated charcoal is for
recent oral ingestion.
Question 6
A nurse is administering furosemide IV push. Which laboratory value requires the most immediate follow-up?
A. Sodium 135 mEq/L
B. Potassium 2.9 mEq/L
C. Glucose 110 mg/dL
D. Creatinine 0.8 mg/dL
