ATI CMS PHARMACOLOGY EXAM – QUESTIONS AND ANSWERS | VERIFIED AND WELL
DETAILED ANSWERS | PLUS RATIONALES | GUARANTEED PASS | LATEST EXAM UPDATE
Core Domains
* Pharmacokinetics and Pharmacodynamics
* Adverse Drug Effects and Contraindications
* Medication Administration and Safety
* Drug-Drug and Drug-Food Interactions
* Dosage Calculations and Conversions
* Patient Education and Compliance
* Regulatory Standards and Ethics
* Crisis Management and Toxicity
Introduction
*The ATI CMS Pharmacology Exam is designed to evaluate a nurse's comprehensive
understanding of medication therapy and safe drug administration. This assessment
measures foundational knowledge regarding drug classifications, mechanism of action,
therapeutic effects, and potential adverse reactions. The structure incorporates both
standard multiple-choice questions and complex clinical scenarios to test critical thinking
skills. By emphasizing real-world application, the exam ensures that candidates can
effectively manage medication regimens, identify contraindications, and provide evidence-
based patient education. Success on this assessment demonstrates the clinical decision-
making capabilities essential for maintaining patient safety and achieving optimal
therapeutic outcomes in diverse healthcare settings.*
Section One: Questions 1–100
1. A nurse is preparing to administer furosemide to a client with heart failure. Which
laboratory value should the nurse review before administration? A. Serum potassium
B. Serum glucose C. Blood urea nitrogen D. Serum creatinine A. Serum potassium
Explanation: Furosemide is a loop diuretic that causes the excretion of
potassium. Monitoring serum potassium levels is essential to prevent hypokalemia.
2. A client is prescribed warfarin for atrial fibrillation. Which food choice should the
nurse teach the client to consume in consistent amounts? A. Spinach B. Bananas C.
Dairy products D. Whole grains A. Spinach Explanation: Spinach is high in
, vitamin K, which antagonizes the effects of warfarin. Consistent intake is necessary to
maintain a stable International Normalized Ratio (INR).
3. A client is receiving morphine sulfate for post-operative pain. Which assessment is
the priority for the nurse? A. Bowel sounds B. Respiratory rate C. Blood pressure D.
Urine output B. Respiratory rate Explanation: Opioid analgesics, such as
morphine, can cause respiratory depression. Monitoring the respiratory rate is the
primary safety priority.
4. A nurse is teaching a client about the use of albuterol for acute asthma attacks. What
is the expected therapeutic effect? A. Increased airway resistance B. Dilation of
bronchial smooth muscle C. Inhibition of histamine release D. Reduction of airway
inflammation B. Dilation of bronchial smooth muscle Explanation: Albuterol
is a short-acting beta2-agonist that causes bronchodilation to relieve bronchospasms
during an asthma attack.
5. A client is taking lisinopril for hypertension and reports a persistent, dry cough. What
should the nurse explain as the cause? A. Accumulation of bradykinin B.
Bronchospasm C. Excess histamine D. Pulmonary edema A. Accumulation of
bradykinin Explanation: ACE inhibitors like lisinopril inhibit the breakdown of
bradykinin, which often leads to the side effect of a persistent, dry cough.
6. A nurse is preparing to administer insulin glargine to a client. What is the unique
characteristic of this insulin? A. It has a rapid onset B. It is a peakless insulin C. It must
be mixed with NPH D. It should be administered before every meal B. It is a
peakless insulin Explanation: Insulin glargine is a long-acting basal insulin that
provides a steady release of insulin throughout a 24-hour period without a defined
peak.
7. A client is prescribed phenytoin for seizure control. Which clinical finding should the
nurse identify as a common adverse effect? A. Gingival hyperplasia B. Respiratory
depression C. Hypotension D. Bradycardia A. Gingival hyperplasia
Explanation: Gingival hyperplasia, or overgrowth of gum tissue, is a well-known
chronic adverse effect of phenytoin therapy.
8. A client is being treated with vancomycin for a severe infection. The nurse observes
flushing of the face, neck, and upper torso. What should the nurse do first? A.
Administer an antihistamine B. Stop the infusion C. Slow the rate of infusion D.
Obtain a blood culture C. Slow the rate of infusion Explanation: Red man
syndrome is an infusion-related reaction often caused by administering vancomycin
too rapidly. Slowing the infusion is the first corrective action.
9. A client is prescribed levothyroxine for hypothyroidism. What should the nurse
include in the teaching plan? A. Take the medication with breakfast B. Take the
, medication on an empty stomach C. Monitor for weight gain D. Discontinue if heart
rate increases B. Take the medication on an empty stomach Explanation:
Levothyroxine absorption is significantly reduced when taken with food. It must be
taken on an empty stomach, usually 30 to 60 minutes before breakfast.
10. A nurse is administering heparin via subcutaneous injection. Which action is correct?
A. Aspirate before injecting B. Massage the site after injection C. Inject into the
abdominal tissue D. Use a 1-inch needle C. Inject into the abdominal tissue
Explanation: Heparin should be administered into the fatty tissue of the abdomen.
Aspirating or massaging the site can cause bruising or hematoma formation.
11. A nurse is caring for a client receiving spironolactone. Which dietary instruction is
appropriate? A. Increase intake of potassium-rich foods B. Avoid salt substitutes
containing potassium C. Limit intake of calcium D. Increase fluid intake B. Avoid
salt substitutes containing potassium Explanation: Spironolactone is a potassium-
sparing diuretic. Avoiding potassium-rich salt substitutes prevents the risk of
hyperkalemia.
12. A client is prescribed simvastatin for hyperlipidemia. Which statement by the client
indicates an understanding of the teaching? A. I will take this medication in the
morning B. I will report any unexplained muscle pain C. I will avoid taking this with
grapefruit juice D. I will discontinue the drug if I feel dizzy B. I will report any
unexplained muscle pain Explanation: Statin-induced myopathy (muscle pain)
can progress to rhabdomyolysis, a serious side effect that requires immediate
reporting and medical evaluation.
13. A nurse is administering digoxin to a client. Which assessment finding requires
withholding the dose? A. Heart rate of 52 beats per minute B. Blood pressure of
110/70 mmHg C. Serum potassium of 4.2 mEq/L D. Digoxin level of 1.2 ng/mL A.
Heart rate of 52 beats per minute Explanation: Digoxin should be withheld if the
apical heart rate is below 60 beats per minute in an adult due to the risk of
bradycardia.
14. A client is prescribed metformin for type 2 diabetes. The nurse recognizes the
medication works by: A. Stimulating insulin release from the pancreas B. Increasing
insulin sensitivity and reducing hepatic glucose production C. Delaying the absorption
of carbohydrates in the intestine D. Directly replacing insulin B. Increasing insulin
sensitivity and reducing hepatic glucose production Explanation: Metformin
decreases hepatic glucose production and increases insulin sensitivity, helping to
lower blood glucose levels without stimulating insulin release.
15. A client receives a prescription for clopidogrel. The nurse understands this
medication is used to: A. Dissolve existing blood clots B. Prevent platelet aggregation
