Practice Exam | Instant Pdf Download
📘 Introduction
This comprehensive ATI RN Pharmacology Proctored Exam study guide is designed to help
nursing students master essential medication concepts and pass ATI and NCLEX-style exams
with confidence. It includes high-yield multiple-choice questions with correct answers and clear
rationales to strengthen understanding of pharmacology principles, drug safety, and clinical
decision-making. The content focuses on commonly tested ATI topics such as medication
classifications, adverse effects, nursing priorities, and patient safety interventions.
Coverage
This exam preparation resource covers key pharmacology areas including cardiovascular
medications, antihypertensives, anticoagulants, and cardiac glycosides; endocrine drugs such as
insulin, oral hypoglycemics, and thyroid medications; respiratory drugs including
bronchodilators and corticosteroids; neurological and psychiatric medications such as
antidepressants, antipsychotics, anticonvulsants, and anxiolytics; anti-infective agents including
antibiotics, antivirals, and antitubercular drugs; gastrointestinal medications such as PPIs,
antacids, and antiemetics; pain management including opioids and NSAIDs; as well as
emergency drugs, antidotes, electrolyte-balancing agents, and safety-focused nursing priorities
aligned with ATI and NCLEX exam standards.
1. A client is prescribed digoxin for heart failure management. Which finding requires
the nurse to hold the medication?
A. Heart rate 78 bpm
B. Heart rate 84 bpm
C. Heart rate 52 bpm
D. Blood pressure 118/76 mmHg
,Explanation: Digoxin must be withheld when heart rate is below 60 because it may worsen
bradycardia and cause toxicity.
2. A nurse is teaching a client taking warfarin therapy. Which instruction is most
appropriate?
A. Increase intake of vitamin K foods daily
B. Stop medication when feeling better
C. Maintain consistent vitamin K intake without sudden changes
D. Take aspirin to improve effectiveness
Explanation: Warfarin effectiveness depends on stable vitamin K levels, so sudden dietary
changes can cause bleeding or clotting risks.
3. Which medication is the antidote for opioid overdose?
A. Flumazenil
B. Atropine
C. Naloxone
D. Protamine sulfate
Explanation: Naloxone rapidly reverses respiratory depression caused by opioid
medications and is the emergency treatment for overdose situations.
4. A client is taking furosemide. Which laboratory value should the nurse monitor
closely?
A. Sodium level
B. Calcium level
C. Potassium level
D. Hemoglobin level
Explanation: Furosemide causes potassium loss through urine, which may lead to
dangerous hypokalemia and cardiac arrhythmias.
5. What is the primary therapeutic effect of beta blockers?
,A. Increase heart rate
B. Stimulate central nervous system
C. Decrease heart rate and blood pressure
D. Increase cardiac output
Explanation: Beta blockers reduce sympathetic stimulation, leading to lower heart rate and
decreased blood pressure for cardiac protection.
6. A client prescribed metformin should be instructed to take the medication:
A. On an empty stomach only
B. With alcohol for better absorption
C. With meals to reduce gastrointestinal side effects
D. Only when blood sugar is high
Explanation: Taking metformin with food reduces nausea, vomiting, and gastrointestinal
discomfort commonly associated with the medication.
7. Which insulin has the fastest onset of action?
A. NPH insulin
B. Regular insulin
C. Insulin lispro
D. Insulin glargine
Explanation: Insulin lispro is rapid-acting and begins lowering blood glucose within minutes
after administration.
8. Which adverse effect is commonly associated with ACE inhibitors?
A. Constipation
B. Tachycardia
C. Dry persistent cough
D. Hyperglycemia
Explanation: ACE inhibitors increase bradykinin levels, which often causes a chronic dry
cough in many patients.
9. Which medication requires monitoring for ototoxicity?
, A. Amoxicillin
B. Metronidazole
C. Gentamicin
D. Doxycycline
Explanation: Aminoglycosides like gentamicin can damage the inner ear, leading to
hearing loss and balance problems.
10. What is the antidote for heparin overdose?
A. Vitamin K
B. Naloxone
C. Protamine sulfate
D. Acetylcysteine
Explanation: Protamine sulfate binds and neutralizes heparin, reversing its anticoagulant
effects during bleeding emergencies.
11. A major side effect of opioid analgesics is:
A. Hypertension
B. Diarrhea
C. Respiratory depression
D. Increased alertness
Explanation: Opioids suppress the respiratory center in the brain, which can lead to life-
threatening breathing depression.
12. A client taking lithium should be instructed to maintain:
A. Low sodium diet
B. No fluid intake
C. Normal sodium and consistent fluid intake
D. High potassium diet
Explanation: Sodium imbalance can increase lithium toxicity, so consistent hydration and
sodium intake are essential for safety.
13. Which medication is first-line treatment for anaphylaxis?
