(Introduction)
This comprehensive examination is designed to evaluate foundational
knowledge, critical thinking, and advanced clinical judgment in nursing
pharmacology. The primary purpose of this assessment is to prepare
candidates for high-stakes nursing board exams by measuring core
competencies related to safe drug administration, therapeutic efficacy,
potential adverse drug reactions, and patient monitoring. The assessment
evaluates essential skills including precise dosage calculations,
identification of drug-drug interactions, recognition of contraindications,
and adherence to professional legal and safety standards. Featuring a
robust combination of direct multiple-choice questions and complex
clinical scenarios, the test emphasizes real-world application and
prioritized clinical decision-making. Candidates are challenged to analyze
patient histories, interpret laboratory values, and determine appropriate
nursing interventions to ensure optimal therapeutic outcomes and patient
safety across diverse clinical environments.
Question 1
A nurse is preparing to administer digoxin to a client with heart failure.
Which assessment finding should prompt the nurse to withhold the
medication and notify the primary healthcare provider?
A. Blood pressure of 130/80 mmHg
B. Serum potassium level of 4.2 mEq/L
C. Apical pulse rate of 52 beats/min
D. Respiratory rate of 18 breaths/min
🟢 C. Apical pulse rate of 52 beats/min
,🔴 Explanation: Digoxin has negative chronotropic effects that decrease
the heart rate. An apical pulse below 60 beats/min in an adult client
indicates bradycardia, requiring the nurse to withhold the drug and notify
the provider to prevent toxicity.
Question 2
A client prescribed warfarin therapy has an International Normalized Ratio
(INR) of 4.8. What is the priority nursing action?
A. Document the finding and continue routine monitoring
B. Prepare to administer protamine sulfate immediately
C. Assess the client for signs of bleeding and notify the provider
D. Encourage the client to increase dietary intake of green leafy
vegetables
🟢 C. Assess the client for signs of bleeding and notify the provider
🔴 Explanation: The therapeutic range for standard warfarin therapy
typically falls between 2.0 and 3.0. An INR of 4.8 is elevated, increasing
the risk of hemorrhage. The nurse must assess for bleeding and notify the
provider, who may order vitamin K or a dosage adjustment.
Question 3
Which instruction is most critical for a client newly prescribed a sublingual
nitroglycerin tablet for angina pectoris?
A. Swallow the tablet whole with a full glass of water immediately upon
chest pain onset.
B. Store the tablets in their original dark, airtight glass container away
from moisture.
C. Take up to five tablets every two minutes if chest pain persists before
calling emergency services.
D. Chew the tablet thoroughly to ensure rapid absorption through the
gastric mucosa.
🟢 B. Store the tablets in their original dark, airtight glass container away
from moisture.
🔴 Explanation: Sublingual nitroglycerin is extremely labile and loses
potency when exposed to light, heat, moisture, or air. It must be stored in
its original amber glass container with a tight lid. It is placed under the
tongue, not swallowed or chewed.
Question 4
,A client is receiving an IV infusion of regular insulin for diabetic
ketoacidosis. Which electrolyte value requires the most immediate
attention by the nurse?
A. Sodium 138 mEq/L
B. Potassium 2.9 mEq/L
C. Calcium 9.2 mg/dL
D. Chloride 101 mEq/L
🟢 B. Potassium 2.9 mEq/L
🔴 Explanation: Insulin shifts potassium into the cells, which can rapidly
worsen hypokalemia. A potassium level of 2.9 mEq/L is critically low and
can precipitate life-threatening cardiac dysrhythmias; potassium
replacement must be initiated before or concurrently with insulin
administration.
Question 5
A client with severe rheumatoid arthritis is prescribed methotrexate.
Which laboratory monitoring is essential for this client?
A. Complete blood count and liver function tests
B. Serum amylase and lipase levels
C. Fasting blood glucose and hemoglobin A1c
D. Thyroid-stimulating hormone and free T4
🟢 A. Complete blood count and liver function tests
🔴 Explanation: Methotrexate is a potent immunosuppressant and
antimetabolite that can cause bone marrow suppression and
hepatotoxicity. Regular monitoring of complete blood counts and liver
enzymes is vital to detect early toxicity.
Question 6
A nurse is providing discharge instructions to a client prescribed
levothyroxine for hypothyroidism. Which statement by the client indicates
an understanding of the teaching?
A. "I should take this medication in the evening right before I go to sleep."
B. "I can stop taking the medication once my weight returns to normal."
C. "I should take this medication on an empty stomach with a full glass of
water every morning."
D. "I should take it with an antacid if it causes any stomach upset."
, 🟢 C. "I should take this medication on an empty stomach with a full
glass of water every morning."
🔴 Explanation: Levothyroxine absorption is significantly reduced by food
and certain minerals. It must be taken on an empty stomach, typically 30
to 60 minutes before breakfast, with a full glass of water.
Question 7
An adult client is prescribed furosemide 40 mg IV push. What is the most
critical adverse effect for the nurse to monitor during and after
administration?
A. Hyperglycemia
B. Ototoxicity
C. Weight gain
D. Hypercalcemia
🟢 B. Ototoxicity
🔴 Explanation: Furosemide is a loop diuretic that can cause ototoxicity,
particularly if administered rapidly via IV push or when combined with
other ototoxic drugs. Tinnitus and hearing loss are hallmark signs.
Question 8
A client with type 2 diabetes mellitus is scheduled for a computed
tomography (CT) scan with intravenous iodinated contrast media. Which
medication must be temporarily discontinued to prevent acute kidney
injury and lactic acidosis?
A. Glipizide
B. Metformin
C. Insulin glargine
D. Sitagliptin
🟢 B. Metformin
🔴 Explanation: Iodinated contrast media can cause acute kidney
impairment, leading to decreased excretion of metformin. This
accumulation significantly increases the risk of life-threatening lactic
acidosis. Metformin is typically withheld for 48 hours post-procedure.
