Introduction
*This comprehensive examination is designed to assess the essential knowledge, clinical reasoning, and
decision-making skills required for success in NUR 139 – Comprehensive Nursing Review. The exam evaluates
foundational theory, applied professional nursing concepts, regulatory compliance, ethical standards, and real-
world clinical scenarios. Each multiple-choice question reflects current evidence-based practice and emphasizes
critical thinking, prioritization, delegation, and patient safety. Questions are structured to mirror NCLEX-style
formats, requiring integration of nursing knowledge across the lifespan and various healthcare settings.
Successful completion of this assessment indicates readiness for clinical practice and advanced nursing
coursework.*
,SECTION ONE: QUESTIONS 1–100
Question 1
A nurse is assessing a postoperative patient who reports sudden chest pain and shortness of breath. The
patient’s oxygen saturation is 88% on room air. Which action should the nurse take first?
A. Administer prescribed morphine sulfate
B. Apply supplemental oxygen via nasal cannula
C. Notify the healthcare provider immediately
D. Elevate the head of the bed to 90 degrees
🟢B
🔴 RATIONALE: The priority action is to apply supplemental oxygen to address the hypoxemia indicated by the
88% oxygen saturation. Airway and breathing take precedence over pain management, provider notification, or
positioning changes, although all may follow after oxygenation is initiated.
Question 2
A patient with heart failure is prescribed furosemide 40 mg IV push. Which laboratory value requires the nurse
to hold the medication and contact the healthcare provider?
A. Serum sodium 135 mEq/L
B. Serum potassium 2.9 mEq/L
C. Serum creatinine 1.0 mg/dL
D. Blood glucose 110 mg/dL
,🟢B
🔴 RATIONALE: Furosemide is a loop diuretic that can cause hypokalemia. A serum potassium of 2.9 mEq/L is
critically low and increases the risk of cardiac dysrhythmias. The medication should be held, and the provider
notified for potassium replacement orders.
Question 3
A nurse is providing discharge teaching to a patient with a new diagnosis of Type 1 diabetes. Which statement
by the patient indicates a correct understanding of hypoglycemia management?
A. “I will drink 8 ounces of orange juice if my blood sugar is below 70 mg/dL.”
B. “I should take an extra dose of insulin if I feel shaky and sweaty.”
C. “I will eat a large meal immediately when my blood sugar is low.”
D. “I can ignore mild hypoglycemia if I am not dizzy.”
🟢A
🔴 RATIONALE: The rule of 15 for hypoglycemia (blood glucose <70 mg/dL) recommends consuming 15 grams
of fast-acting carbohydrates, such as 8 ounces of orange juice. Insulin would worsen hypoglycemia, large meals
delay rapid glucose elevation, and ignoring symptoms is dangerous.
Question 4
Which ethical principle is primarily violated when a nurse fails to obtain informed consent before a procedure?
A. Beneficence
B. Nonmaleficence
C. Autonomy
D. Justice
, 🟢C
🔴 RATIONALE: Autonomy respects a patient’s right to make informed decisions about their own care. Failure
to obtain informed consent directly violates this principle by denying the patient the opportunity to understand
and agree to a procedure voluntarily.
Question 5
A nurse is caring for a patient with a nasogastric (NG) tube set to low intermittent suction. The patient’s
morning electrolyte panel reveals a potassium level of 3.2 mEq/L. Which assessment finding is most consistent
with this lab value?
A. Hyperactive bowel sounds
B. Flattened T waves on ECG
C. Elevated blood pressure
D. Decreased urine output
🟢B
🔴 RATIONALE: Hypokalemia (potassium <3.5 mEq/L) commonly causes flattened T waves, ST depression, and
U waves on ECG. Hyperactive bowel sounds are not typical; instead, hypokalemia causes hypoactive bowel
sounds. Hypertension and decreased urine output are not primary signs.
Question 6
A charge nurse is delegating tasks to licensed practical nurses (LPNs) and unlicensed assistive personnel (UAP).
Which task is most appropriate for the LPN?
A. Measuring a patient’s intake and output
B. Administering a tube feeding to a stable patient
