Introduction
This comprehensive examination is designed to rigorously assess the cognitive and
clinical knowledge required for the Certified Critical Care Nursing (CCRN)
credential. The content is centered on the advanced assessment, diagnosis, and
management of acutely and critically ill adult patients. The following 200 multiple-
choice questions integrate foundational theory with applied professional knowledge,
emphasizing real-world clinical decision-making and ethical judgment. Each
question is structured as a scenario-based or direct-knowledge item, challenging
the candidate to prioritize, analyze, and intervene effectively. The examination also
tests regulatory compliance, professional standards, and the psychosocial aspects of
critical care nursing. Successful completion of this assessment indicates readiness
for the professional certification examination.

SECTION ONE: QUESTIONS 1–50
════════════════════════════════════
1. A 65-year-old patient is admitted with acute respiratory distress syndrome
(ARDS). Which finding indicates that the patient's condition is deteriorating
despite current management?
A. Decreased plateau pressure
B. Increased PaO2/FiO2 ratio
C. Increased minute ventilation
D. Decreased lung compliance
🟢 Correct Answer: D. Decreased lung compliance
🔴 Explanation: Decreased lung compliance is a hallmark of ARDS progression
due to increasing alveolar stiffness and fluid accumulation. A decreasing
PaO2/FiO2 ratio, not increased, is a sign of deterioration.
2. A patient is experiencing ventricular tachycardia without a pulse. Which
immediate action should the nurse anticipate?
A. Synchronized cardioversion
B. Defibrillation
C. Administration of amiodarone
D. Placement of a transvenous pacemaker
🟢 Correct Answer: B. Defibrillation
🔴 Explanation: Pulseless ventricular tachycardia is a shockable rhythm. The
immediate treatment is defibrillation, not synchronized cardioversion, which is
used for stable tachyarrhythmias.
,3. The nurse is monitoring a patient with an intracranial pressure (ICP) monitor.
Which finding would be most concerning?
A. ICP of 18 mm Hg
B. Cerebral perfusion pressure (CPP) of 55 mm Hg
C. Mean arterial pressure (MAP) of 90 mm Hg
D. ICP waveform showing consistent P1 and P2 waves
🟢 Correct Answer: B. Cerebral perfusion pressure (CPP) of 55 mm Hg
🔴 Explanation: CPP should be maintained above 60 mm Hg to ensure adequate
cerebral blood flow. A CPP of 55 mm Hg indicates inadequate perfusion and risk
of ischemia.
4. Which assessment parameter is most indicative of hypovolemic shock in a
patient with a gastrointestinal bleed?
A. Warm, dry skin
B. Bounding peripheral pulses
C. Decreased urine output
D. Increased central venous pressure (CVP)
🟢 Correct Answer: C. Decreased urine output
🔴 Explanation: In hypovolemic shock, decreased renal perfusion leads to oliguria
(urine output < 0.5 mL/kg/hr). Cold, clammy skin and weak, thready pulses are
typical.
5. A patient post-cardiac arrest is being targeted temperature managed (TTM).
Which complication is most associated with this therapy?
A. Severe hypokalemia
B. Increased risk of dysrhythmias
, C. Decreased serum glucose
D. Coagulopathy
🟢 Correct Answer: D. Coagulopathy
🔴 Explanation: Hypothermia impairs platelet function and coagulation cascade
enzymes, increasing the risk of bleeding. While bradycardia is expected,
coagulopathy is a significant complication.
6. A 72-year-old patient with a history of heart failure is receiving intravenous
furosemide. Which laboratory value requires immediate attention?
A. Serum sodium of 136 mEq/L
B. Serum potassium of 3.2 mEq/L
C. BUN of 24 mg/dL
D. Serum creatinine of 1.3 mg/dL
🟢 Correct Answer: B. Serum potassium of 3.2 mEq/L
🔴 Explanation: Loop diuretics can cause significant hypokalemia. A serum
potassium of 3.2 mEq/L is dangerously low and can lead to cardiac dysrhythmias,
requiring prompt replacement.
7. When evaluating a patient's arterial blood gas (ABG) results: pH 7.25, PaCO2
55 mm Hg, HCO3 24 mEq/L. Which condition does this indicate?
A. Metabolic acidosis
B. Metabolic alkalosis
C. Respiratory acidosis
D. Respiratory alkalosis
🟢 Correct Answer: C. Respiratory acidosis
🔴 Explanation: A low pH (acidemia) with an elevated PaCO2 (>45 mm Hg) and a
normal HCO3 indicates acute respiratory acidosis due to alveolar hypoventilation.
