*Introduction*
*The purpose of this assessment is to evaluate the clinical proficiency of nursing
candidates regarding pharmacology principles essential for safe patient care. This exam
measures the ability to apply foundational pharmacological knowledge to complex clinical
scenarios, emphasizing patient safety, accurate dosage calculation, and critical decision-
making in diverse settings. Comprising multiple-choice and scenario-based questions, the
exam requires examinees to synthesize information regarding drug interactions, mechanism
of action, and professional nursing responsibilities. Success on this assessment demonstrates
the competency required to manage medication therapy effectively, uphold regulatory
standards, and ensure optimal patient outcomes through evidence-based practice and
professional clinical judgment.*
Section One: Questions 1–100
1. A nurse is preparing to administer digoxin to a client with heart failure. Which of the
following findings should the nurse identify as an indication to withhold the
medication? A. Potassium level 4.2 mEq/L B. Apical pulse 52/min C. Blood pressure
110/70 mmHg D. Digoxin level 0.8 ng/mL B. Apical pulse 52/min Explanation:
Digoxin should be withheld if the apical pulse is less than 60/min in an adult due to
the risk of symptomatic bradycardia.
,2. A client is prescribed lisinopril for hypertension. The nurse should instruct the client
to avoid which of the following over-the-counter supplements? A. Potassium
supplements B. Vitamin C C. Magnesium D. Fish oil A. Potassium supplements
Explanation: ACE inhibitors like lisinopril can cause potassium retention;
therefore, potassium supplements or salt substitutes containing potassium are
contraindicated due to the risk of hyperkalemia.
3. A nurse is caring for a client who is receiving vancomycin IV. The client develops
flushing, tachycardia, and hypotension. Which action should the nurse take first? A.
Administer diphenhydramine B. Slow the infusion rate C. Stop the infusion D. Obtain
a blood culture C. Stop the infusion Explanation: The client is exhibiting signs
of Red Man Syndrome, a reaction to rapid vancomycin infusion. The priority action is
to stop the medication immediately.
4. A nurse is teaching a client about the use of albuterol for acute asthma
exacerbations. Which statement by the client indicates understanding? A. I should
take this medication every 4 hours to prevent attacks B. This medication is used as a
rescue inhaler for acute symptoms C. I should expect a decrease in my heart rate
after use D. This medication will take 2 hours to start working B. This medication
is used as a rescue inhaler for acute symptoms Explanation: Albuterol is a short-
acting beta2-agonist used as a rescue medication for immediate bronchodilation
during acute asthma attacks.
5. A client is prescribed warfarin for atrial fibrillation. Which laboratory value should the
nurse monitor to assess the effectiveness of the therapy? A. PTT B. INR C. Platelet
count D. Hematocrit B. INR Explanation: The International Normalized Ratio
(INR) is the standard test used to monitor the therapeutic effectiveness of warfarin
therapy.
6. A nurse is preparing to administer insulin glargine to a client with type 1 diabetes
mellitus. Which of the following is correct regarding this insulin? A. It has a peak
effect in 2 hours B. It can be mixed with regular insulin in the same syringe C. It
provides a steady basal rate of insulin coverage D. It should be administered only
before meals C. It provides a steady basal rate of insulin coverage
Explanation: Insulin glargine is a long-acting insulin that does not have a defined peak
and is used to provide consistent basal coverage throughout the day.
7. A nurse is caring for a client receiving phenytoin for seizure control. Which side effect
should the nurse monitor for? A. Gingival hyperplasia B. Hypertension C. Excessive
weight loss D. Hearing loss A. Gingival hyperplasia Explanation: Phenytoin is
well-known to cause gingival hyperplasia, requiring the nurse to teach the client
about meticulous oral hygiene and regular dental checkups.
, 8. A client is prescribed furosemide 40 mg PO daily. Which assessment finding is the
priority for the nurse to monitor? A. Serum glucose B. Serum potassium C. Blood
urea nitrogen D. Daily weight B. Serum potassium Explanation: Furosemide is
a loop diuretic that causes significant potassium excretion, making hypokalemia a
primary risk that requires monitoring.
9. A nurse is reviewing a prescription for sumatriptan for a client with migraines. Which
condition in the client's history is a contraindication? A. Asthma B. Coronary artery
disease C. Hypothyroidism D. Peptic ulcer disease B. Coronary artery disease
Explanation: Sumatriptan is a triptan used for migraines that causes vasoconstriction,
which is contraindicated in clients with underlying coronary artery disease.
10. A nurse is administering subcutaneous enoxaparin. Which technique is correct? A.
Aspirate before injecting the medication B. Expel the air bubble from the prefilled
syringe C. Administer the injection in the abdomen D. Massage the site vigorously
after injection C. Administer the injection in the abdomen Explanation:
Enoxaparin is administered in the abdomen, at least 2 inches from the umbilicus. Air
bubbles should not be expelled, and the site should not be massaged.
11. A nurse is monitoring a client receiving IV magnesium sulfate for preeclampsia.
Which finding requires immediate intervention? A. Absence of deep tendon reflexes
B. Respiratory rate of 16/min C. Urinary output of 40 mL/hr D. Blood pressure of
140/90 mmHg A. Absence of deep tendon reflexes Explanation: The loss of
deep tendon reflexes is an early sign of magnesium toxicity, necessitating the
immediate discontinuation of the infusion.
12. A client is taking lithium carbonate for bipolar disorder. Which teaching point is
essential? A. Restrict sodium intake to less than 2g daily B. Maintain consistent fluid
and sodium intake C. Avoid all caffeine and sugar D. Discontinue the medication if
weight gain occurs B. Maintain consistent fluid and sodium intake
Explanation: Lithium levels are affected by sodium and fluid balance; the client must
maintain consistent intake to avoid toxicity or sub-therapeutic levels.
13. A nurse is providing discharge instructions for a client taking tetracycline. Which
instruction should the nurse include? A. Take the medication with milk to prevent
stomach upset B. Wear protective clothing and sunscreen outdoors C. Stop the
medication once symptoms subside D. Expect dark stools while on this therapy B.
Wear protective clothing and sunscreen outdoors Explanation: Tetracyclines
cause photosensitivity; clients must be instructed to use sun protection to prevent
severe sunburn.
14. A nurse is caring for a client who is receiving neostigmine for myasthenia gravis.
Which finding should the nurse identify as an adverse reaction? A. Constipation B.
