Introduction
This comprehensive examination is designed to assess mastery of pharmacological concepts essential for nursing
practice. It evaluates foundational knowledge of drug classifications, mechanisms of action, side effects, and
therapeutic uses, alongside the application of this knowledge in clinical scenarios. The exam emphasizes critical
thinking, decision-making, and the ability to prioritize patient safety, including the management of adverse effects,
drug interactions, and legal and ethical considerations. Featuring a multiple-choice and scenario-based format,
this assessment prepares candidates to integrate pharmacological principles into safe, patient-centered care in
real-world settings.
SECTION ONE: QUESTIONS 1 – 100
,1. A client with a history of peptic ulcer disease is prescribed prednisone for an acute exacerbation of
rheumatoid arthritis. Which intervention is most important to prevent a serious adverse effect?
A. Administer the medication with food
B. Monitor for signs of hyperglycemia
C. Prescribe a proton pump inhibitor
D. Instruct the client to take the medication in the morning
🟢 C. Prescribe a proton pump inhibitor
🔴 RATIONALE: Prednisone is a corticosteroid that increases the risk of gastric ulcer formation. Co-
administration with a proton pump inhibitor (PPI) is a key preventative strategy to reduce gastric acid secretion
and protect the gastric mucosa, thereby minimizing the risk of peptic ulcer disease exacerbation.
2. A nurse is preparing to administer digoxin to a client with heart failure. Which assessment finding would
indicate a need to withhold the medication and notify the healthcare provider?
A. Heart rate of 58 beats per minute
B. Serum potassium level of 3.2 mEq/L
C. Blood pressure of 110/70 mmHg
D. Respiratory rate of 18 breaths per minute
🟢 B. Serum potassium level of 3.2 mEq/L
🔴 RATIONALE: Digoxin toxicity is potentiated by hypokalemia. A serum potassium level of 3.2 mEq/L is below
the normal range (3.5-5.0 mEq/L), increasing the risk of fatal cardiac dysrhythmias. The nurse should hold the
digoxin and notify the provider for potassium replacement.
3. A client is prescribed an MAOI for depression. The nurse should instruct the client to avoid which food to
prevent a hypertensive crisis?
A. Aged cheese
B. Grapefruit juice
,C. Bananas
D. Milk
🟢 A. Aged cheese
🔴 RATIONALE: MAOIs inhibit the breakdown of tyramine. Aged cheeses are high in tyramine, and their
ingestion can lead to a rapid, dangerous increase in blood pressure (hypertensive crisis). Clients must avoid
tyramine-rich foods like aged cheeses, cured meats, and fermented products.
4. Which of the following assessment findings in a client taking furosemide is indicative of a potential
adverse effect?
A. Serum sodium level of 140 mEq/L
B. Serum potassium level of 3.0 mEq/L
C. Serum calcium level of 10.0 mg/dL
D. Blood glucose level of 90 mg/dL
🟢 B. Serum potassium level of 3.0 mEq/L
🔴 RATIONALE: Furosemide is a loop diuretic that can cause significant hypokalemia due to increased
potassium excretion in the distal tubule. A potassium level of 3.0 mEq/L is below the normal range and can lead
to cardiac dysrhythmias and muscle weakness, requiring monitoring and potassium supplementation.
5. A client prescribed warfarin is being discharged. Which statement by the client indicates a need for further
teaching?
A. "I will use a soft toothbrush to brush my teeth."
B. "I will avoid eating large amounts of leafy green vegetables."
C. "I can take ibuprofen for my occasional headaches."
D. "I will keep all my appointments for blood tests."
🟢 C. "I can take ibuprofen for my occasional headaches."
🔴 RATIONALE: Ibuprofen is an NSAID that inhibits platelet aggregation and increases the risk of
, gastrointestinal bleeding. When combined with warfarin, an anticoagulant, the risk of bleeding is significantly
elevated. The client should be advised to use alternative, non-NSAID pain relievers like acetaminophen for
headaches.
6. A healthcare provider orders 1000 mL of 0.9% normal saline to be infused over 8 hours. The drop factor is
15 gtt/mL. What is the drip rate in gtt/min?
A. 31 gtt/min
B. 125 gtt/min
C. 15 gtt/min
D. 20 gtt/min
🟢 A. 31 gtt/min
🔴 RATIONALE: The formula for drip rate is (Volume in mL × Drop factor) / Time in minutes. (1000 mL × 15
gtt/mL) / (8 hours × 60 minutes) = 15, = 31.25. Therefore, the correct drip rate is 31 gtt/min. It's crucial
to calculate IV flow rates accurately to ensure safe and effective fluid administration.
7. A nurse is providing education to a client starting on lisinopril. Which instruction is most important to
prevent a serious adverse reaction?
A. "Take this medication with a full glass of water."
B. "Report any persistent, dry cough to your provider."
C. "Expect some dizziness when standing up quickly."
D. "Avoid potassium supplements while taking this drug."
🟢 D. "Avoid potassium supplements while taking this drug."
🔴 RATIONALE: Lisinopril is an ACE inhibitor that can cause hyperkalemia by reducing aldosterone secretion.
Potassium supplements or potassium-sparing diuretics can further increase serum potassium levels to
dangerous levels, leading to cardiac arrhythmias. This is a critical safety instruction that must be emphasized.
