Introduction:
This comprehensive clinical assessment is designed to evaluate advanced knowledge and practical application of complex
pharmacotherapeutic concepts essential for safe nursing practice. The assessment focuses on high-alert medications, therapeutic
monitoring, dosage calculation safety, and patient-centered education across the lifespan. Through a blend of foundational
pharmacology questions and realistic clinical scenarios, this exam measures critical thinking, clinical judgment, and regulatory
compliance under professional standards. Candidates are challenged to prioritize nursing interventions, identify critical drug-drug
interactions, analyze adverse effects, and make informed clinical decisions to optimize therapeutic outcomes and ensure patient
safety.*
SECTION ONE
Question 1
A nurse is preparing to administer digoxin to a patient with heart failure. Which of the following laboratory values should the nurse check
before administration to minimize the risk of digoxin toxicity?
A. Serum sodium level of 140 mEq/L
🟢 B. Serum potassium level of 3.2 mEq/L
,C. Serum calcium level of 9.5 mg/dL
D. Serum magnesium level of 2.0 mEq/L
🔴 RATIONALE: Hypokalemia (low potassium) greatly increases the risk of digoxin toxicity because potassium and digoxin compete for the
same binding sites on the Na+/K+ ATPase pump. When potassium is low, more digoxin binds, magnifying its therapeutic and toxic effects.
Question 2
A patient is prescribed sublingual nitroglycerin for acute angina pectoris. Which instruction is most critical for the nurse to include in the
patient's teaching plan?
🟢 A. Place the tablet under the tongue and allow it to dissolve completely without swallowing.
B. Take the tablet with a full glass of water to ensure rapid absorption.
C. Chew the tablet thoroughly before swallowing to accelerate onset of action.
D. Store the medication in a clear plastic container on the kitchen windowsill.
🔴 RATIONALE: Sublingual nitroglycerin must bypass the first-pass hepatic metabolism by absorbing directly through the oral mucosa.
Swallowing or chewing the medication inactivates it. It should be kept in its original dark glass bottle to prevent degradation from light and
moisture.
Question 3
A nurse is reviewing the medication administration record of a patient who has been prescribed spironolactone. Which of the following
concurrent medications requires immediate intervention by the nurse?
A. Furosemide
B. Metoprolol
🟢 C. Lisinopril
D. Atorvastatin
🔴 RATIONALE: Both spironolactone (a potassium-sparing diuretic) and lisinopril (an ACE inhibitor) promote potassium retention. Concurrent
use significantly increases the risk of severe, life-threatening hyperkalemia.
Question 4
A patient is receiving an intravenous heparin infusion for a deep vein thrombosis. The nurse notes that the patient's activated partial
thromboplastin time (aPTT) is 120 seconds. Which action should the nurse take first?
A. Prepare to administer protamine sulfate immediately.
B. Increase the infusion rate according to the hospital nomogram.
🟢 C. Stop the heparin infusion immediately.
D. Draw a repeat blood sample for an aPTT level.
🔴 RATIONALE: An aPTT of 120 seconds is significantly above the typical therapeutic range (usually 60–80 seconds). The immediate priority
is to stop the infusion to prevent severe hemorrhage. Protamine sulfate is the antidote but is reserved for active bleeding or critically high
levels.
Question 5
A patient is starting therapy on atorvastatin. Which laboratory test should the nurse expect the provider to order before initiating this
medication and periodically thereafter?
, A. Blood urea nitrogen (BUN) and creatinine
🟢 B. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST)
C. Complete blood count (CBC) with differential
D. Serum amylase and lipase
🔴 RATIONALE: HMG-CoA reductase inhibitors (statins) can cause hepatotoxicity and muscle damage. Baseline and periodic liver function
tests (ALT and AST) are mandatory to monitor for drug-induced hepatic impairment.
Question 6
A nurse is caring for a patient receiving intravenous gentamicin. To monitor for the most common and serious adverse effects of this
aminoglycoside, which parameters are most important to assess?
🟢 A. Serum creatinine levels and hearing acuity
B. Serum potassium levels and visual fields
C. Liver enzymes and international normalized ratio (INR)
D. Blood glucose levels and deep tendon reflexes
🔴 RATIONALE: Aminoglycosides, such as gentamicin, are highly nephrotoxic and ototoxic. Monitoring renal function (creatinine, BUN) and
evaluating hearing acuity (ototoxicity) are essential safety interventions during therapy.
Question 7
A patient with type 1 diabetes mellitus is prescribed insulin lispro. When should the nurse instruct the patient to administer this medication?
A. 30 to 45 minutes before a meal
B. Immediately after completing a meal
🟢 C. Within 15 minutes of eating a meal
D. At bedtime on an empty stomach
🔴 RATIONALE: Insulin lispro is a rapid-acting insulin with an onset of action of 15 minutes. It must be administered within 15 minutes of
eating to prevent acute hypoglycemia.
Question 8
The nurse is preparing to administer metformin to a patient scheduled for an outpatient CT scan with intravenous contrast media. Which
action is most appropriate?
🟢 A. Hold the metformin on the day of the procedure and for 48 hours afterward.
B. Administer the metformin as scheduled before and after the procedure.
C. Double the metformin dose the day before the scan to prevent hyperglycemia.
D. Administer the metformin with a large volume of orange juice before the scan.
🔴 RATIONALE: Metformin must be withheld prior to and for 48 hours following procedures utilizing iodinated contrast media. The
combination of contrast dye and metformin increases the risk of lactic acidosis and acute renal failure.
Question 9
A patient is prescribed levothyroxine for the treatment of hypothyroidism. Which instruction should the nurse emphasize to ensure optimal
drug absorption?
