INTRODUCTION
,This comprehensive assessment evaluates the breadth of nursing knowledge required for safe, effective entry-
level practice. The examination spans pharmacological interventions, complex disease management, maternal-
child health, psychiatric care, and leadership principles. Candidates must demonstrate clinical reasoning through
multiple-choice and scenario-based items that mirror real-world patient care situations. The test emphasizes
prioritization, delegation, therapeutic communication, and evidence-based decision-making under pressure.
Success requires integration of pathophysiology, assessment skills, and regulatory compliance. Each item
challenges the examinee to apply theoretical foundations to dynamic clinical scenarios, reflecting the critical
thinking demands of contemporary nursing practice. Preparation should focus on systematic analysis, safety
protocols, and interdisciplinary collaboration.
SECTION ONE: QUESTIONS 1–100
Question 1: A nurse is caring for a client with a new diagnosis of heart failure. The client is prescribed
furosemide 40 mg IV push. Which assessment finding indicates the medication is achieving the desired
therapeutic effect?
A. Increased urine output
B. Decreased heart rate
C. Elevated blood pressure
D. Improved oxygen saturation
,🟢 Correct answer: A
🔴 RATIONALE: Furosemide is a loop diuretic that acts on the ascending loop of Henle to promote sodium,
chloride, and water excretion. The primary therapeutic effect in heart failure is the reduction of fluid volume
overload, which is evidenced by increased urine output. While improved oxygen saturation may occur
secondarily as pulmonary edema resolves, increased urine output is the most direct and immediate indicator of
therapeutic effect. Decreased heart rate and elevated blood pressure are not expected primary effects of
furosemide.
Question 2: A nurse is reviewing the laboratory results of a client receiving heparin therapy. Which value should
the nurse monitor to evaluate the effectiveness of this anticoagulant?
A. Platelet count
B. Activated partial thromboplastin time (aPTT)
C. Prothrombin time (PT)
D. International normalized ratio (INR)
🟢 Correct answer: B
🔴 RATIONALE: Heparin therapy is monitored using the activated partial thromboplastin time (aPTT), which
evaluates the intrinsic and common coagulation pathways. The therapeutic range for unfractionated heparin is
typically 1.5 to 2.5 times the control value. Platelet count is monitored to detect heparin-induced
, thrombocytopenia, not effectiveness. PT and INR are used to monitor warfarin therapy, which affects the
extrinsic pathway.
Question 3: A nurse is caring for a client with a nasogastric tube who is receiving continuous tube feeding.
Which action by the nurse demonstrates correct technique?
A. Checking gastric residual every 2 hours
B. Flushing the tube with 30 mL of water before and after medication administration
C. Positioning the client supine during feeding
D. Adding new formula to the existing formula in the feeding bag
🟢 Correct answer: B
🔴 RATIONALE: Flushing the nasogastric tube with 30 mL of water before and after medication administration
prevents tube occlusion and ensures complete medication delivery. Gastric residual should be checked every 4
to 8 hours, not every 2 hours. The client must be positioned with the head of the bed elevated at least 30 to 45
degrees during feeding to prevent aspiration. Adding new formula to existing formula increases bacterial
contamination risk; the bag should be emptied and rinsed before adding fresh formula.
Question 4: A nurse is providing discharge teaching to a client newly diagnosed with type 2 diabetes mellitus.
Which statement by the client indicates a need for further instruction?
