Core Domains:
• Advanced Pathophysiology
• Acute Care Pharmacology
• Hemodynamic Monitoring and Interpretation
• Mechanical Ventilation and Respiratory Management
• Sepsis and Infectious Disease Management
• Acute Coronary Syndromes and Cardiac Emergencies
• Neurological Emergencies
• Renal and Metabolic Disorders in Acute Care

Introduction
This comprehensive examination is designed to rigorously assess the advanced practice nurse's knowledge and clinical
reasoning skills essential for managing complex, acutely ill patients in the intensive care unit and other high-acuity
settings. The following multiple-choice questions cover a broad spectrum of critical care topics, from foundational
pathophysiology and pharmacology to nuanced clinical decision-making in real-world scenarios. Each question is
,crafted to challenge your ability to synthesize data, prioritize interventions, and anticipate potential complications,
reflecting the dynamic and demanding nature of acute care practice. By emphasizing evidence-based guidelines and
patient safety, this exam serves as a vital tool for self-assessment and preparation for board certification, ensuring you
are ready to deliver expert, compassionate care in the most challenging healthcare environments.
SECTION ONE: QUESTIONS 1–50
1. A 68-year-old male with a history of chronic obstructive pulmonary disease (COPD) is admitted with acute
hypoxemic respiratory failure. An arterial blood gas (ABG) on 40% Venturi mask reveals: pH 7.28, PaCO2 68
mmHg, PaO2 55 mmHg, HCO3 30 mEq/L. Which of the following is the most appropriate initial ventilatory
strategy?
A. Assist-control ventilation with a tidal volume of 8 mL/kg of ideal body weight
B. Pressure support ventilation with a high inspiratory pressure
C. Non-invasive positive pressure ventilation (NIPPV)
D. Low tidal volume (6 mL/kg) lung-protective ventilation
🟢 Correct Answer: C. Non-invasive positive pressure ventilation (NIPPV)
,🔴 Explanation: The patient has acute-on-chronic respiratory failure with a compensated respiratory acidosis
(elevated HCO3). NIPPV is the preferred initial strategy to support ventilation and avoid intubation in appropriate
candidates with COPD exacerbation and respiratory failure, as it improves outcomes and reduces mortality. Assist-
control and lung-protective ventilation are invasive options; lung-protective ventilation is primarily for ARDS.
Pressure support alone may not provide adequate minute ventilation in acute failure.
2. A 72-year-old female is admitted with septic shock. Her central venous pressure (CVP) is 4 mmHg and her
mean arterial pressure (MAP) is 52 mmHg. After a 30 mL/kg crystalloid fluid bolus, her MAP remains 55 mmHg.
Which of the following vasopressors is recommended as the first-line agent?
A. Dopamine
B. Norepinephrine
C. Vasopressin
D. Epinephrine
🟢 Correct Answer: B. Norepinephrine
🔴 Explanation: The Surviving Sepsis Campaign guidelines recommend norepinephrine as the first-line vasopressor
for septic shock, particularly when MAP remains low despite fluid resuscitation. It is more effective than dopamine in
improving mortality and is associated with fewer arrhythmias. Vasopressin and epinephrine are second-line or
adjunctive agents.
, 3. Which of the following clinical manifestations is the earliest sign of increased intracranial pressure (ICP) in a
patient with a traumatic brain injury?
A. Ipsilateral pupillary dilation
B. Cushing's triad
C. Decreased level of consciousness
D. Decorticate posturing
🟢 Correct Answer: C. Decreased level of consciousness
🔴 Explanation: A change in level of consciousness (LOC) is the most sensitive and earliest indicator of increasing
ICP. It reflects compression of the reticular activating system in the brainstem. Cushing's triad (hypertension,
bradycardia, irregular respirations) and pupillary changes are late signs of herniation. Decorticate posturing indicates
significant hemispheric damage.
4. A patient with acute myocardial infarction (AMI) develops pulseless ventricular tachycardia. After one
defibrillation attempt and 2 minutes of CPR, the rhythm persists. What is the next appropriate medication to
administer?
A. Amiodarone 300 mg IV push
B. Epinephrine 1 mg IV push
