This comprehensive assessment is designed to evaluate nursing students' and professionals' mastery of adult
medical-surgical nursing concepts essential for clinical practice and NCLEX-RN success. The exam assesses
critical skills including patient assessment, clinical decision-making, nursing interventions, pharmacological
management, and real-world application of medical-surgical principles. Structured as multiple-choice and
scenario-based questions, the test emphasizes critical thinking, prioritization, and evidence-based decision-
making in diverse healthcare settings. Each question reflects real-world clinical scenarios to prepare
candidates for the complexities of adult patient care across medical-surgical environments.
Section One: Questions 1–100
,Question 1
A nurse is caring for a patient with acute heart failure who presents with dyspnea, crackles bilaterally, and
oxygen saturation of 88%. Which intervention should the nurse prioritize?
A. Administer oral fluids to prevent dehydration
B. Apply high-flow oxygen and position the patient in high Fowler's position
C. Administer a beta-blocker immediately
D. Encourage the patient to walk to improve circulation
🟢 Correct answer: B
🔴 RATIONALE: High-flow oxygen and high Fowler's position immediately improve oxygenation and reduce
pulmonary congestion in acute heart failure. Fluid administration (A) worsens volume overload. Beta-blockers
(C) are contraindicated in acute instability. Walking (D) increases oxygen demand.
Question 2
A patient with type 2 diabetes receives insulin at 7 AM. The nurse should monitor for hypoglycemia most closely
during which time period?
A. 9–10 AM
B. 11 AM–1 PM
C. 3–5 PM
D. 9–11 PM
🟢 Correct answer: A
,🔴 RATIONALE: Rapid-acting insulin peaks within 1–2 hours, so hypoglycemia risk is highest at 9–10 AM
after a 7 AM dose. Later time periods correspond to insulin wearing off or basal effects.
Question 3
Which laboratory value is most critical to report immediately in a patient receiving warfarin for deep vein
thrombosis?
A. Sodium 138 mEq/L
B. Prothrombin time (PT) 40 seconds
C. Glucose 110 mg/dL
D. Hemoglobin 14 g/dL
🟢 Correct answer: B
🔴 RATIONALE: PT of 40 seconds is significantly elevated (normal ~11–13.5 seconds), indicating excessive
anticoagulation and bleeding risk. This requires immediate intervention. Other values are within normal limits.
Question 4
A patient with a pneumothorax has a chest tube in place. The nurse observes no tidal movement in the water
seal chamber. What is the most appropriate action?
A. Clamp the chest tube immediately
B. Document as normal and continue monitoring
C. Notify the provider immediately
D. Encourage deep breathing exercises
, 🟢 Correct answer: C
🔴 RATIONALE: Absent tidal movement suggests chest tube obstruction or complete lung re-expansion;
however, sudden absence requires provider evaluation to rule out complications. Clamping (A) is dangerous.
Documentation alone (B) delays care.
Question 5
Which nursing intervention is most appropriate for a patient with early-stage sepsis?
A. Restrict fluid intake
B. Administer broad-spectrum antibiotics within 1 hour
C. Apply warm blankets only
D. Delay laboratory testing
🟢 Correct answer: B
🔴 RATIONALE: Early sepsis management requires antibiotic administration within 1 hour to reduce
mortality. Fluid restriction (A) worsens hypoperfusion. Warm blankets alone (C) don't treat infection. Delaying
labs (D) delays diagnosis.
Question 6
A patient with chronic kidney disease has a potassium level of 6.2 mEq/L. Which medication should the nurse
anticipate administering?
