I. Foundations of Critical Care Nursing
• 1. Introduction to Critical Care:
o Philosophy and principles of critical care nursing.
o Characteristics of critically ill patients.
o The critical care environment (technology, alarms, psychosocial impact).
o Ethical and legal issues in critical care (e.g., end-of-life decisions, withdrawal of care, informed
consent in emergency situations).
o Interprofessional collaboration in the ICU.
• 2. Advanced Assessment and Monitoring:
o Systematic Head-to-Toe Assessment: Rapid and focused assessments for critically ill patients.
o Neurological Assessment: Glasgow Coma Scale (GCS), pupillary response, cranial nerves,
signs of increased intracranial pressure (ICP), subtle changes in mental status.
o Cardiovascular Assessment: Auscultation of heart sounds, peripheral pulses, capillary refill,
skin assessment.
o Respiratory Assessment: Breath sounds, respiratory patterns, work of breathing, accessory
muscle use.
o Gastrointestinal, Genitourinary, Renal, Endocrine, Hematologic, Integumentary
Assessments: Focused critical care assessment for each.
• 3. Hemodynamic Monitoring:
o Basic Principles: Understanding pressure transducers, leveling, zeroing.
o Arterial Lines: Indications, insertion sites, waveform analysis, complications, nursing care.
o Central Venous Pressure (CVP) Monitoring: Indications, waveform analysis, normal values,
interpretation (e.g., fluid status, right ventricular function), nursing care.
o Pulmonary Artery (PA) Catheter (Swan-Ganz): Basic understanding of indications, PAP,
PAWP/PCWP, CO, SVR (though often less heavily tested on initial exams for entry-level critical
care).
o Non-invasive Hemodynamic Monitoring: MAP, pulse pressure variations.
• 4. Fluid, Electrolyte, and Acid-Base Imbalances (Advanced Critical Care Focus):
o Complex Imbalances: Recognition and management of severe hyponatremia, hypernatremia,
hypo/hyperkalemia, hypo/hypercalcemia, hypo/hypermagnesemia, hypo/hyperphosphatemia in
critically ill patients.
o Advanced ABG Interpretation: Compensated vs. uncompensated states, mixed acid-base
disorders.
o Fluid Resuscitation: Types of IV fluids (crystalloids vs. colloids), indications for massive
transfusion.
• 5. Pharmacology in Critical Care:
o Vasoactive Medications: Vasopressors (norepinephrine, dopamine, phenylephrine,
vasopressin), inotropes (dobutamine, milrinone). Indications, mechanisms, titration, adverse
effects, nursing implications.
o Antiarrhythmics: Adenosine, amiodarone, lidocaine.
o Sedation and Analgesia: Propofol, midazolam, fentanyl, hydromorphone. Assessment of
sedation (RASS, SAS), delirium management.
o Neuromuscular Blocking Agents: Indications, nursing care (ventilator synchronization,
protecting eyes/skin, sedation requirements).
o Insulin Infusions: Management of DKA/HHS.
o Anticoagulants/Thrombolytics: Heparin, warfarin, tPA.

, o Diuretics: Furosemide, bumetanide.
II. Management of Critical Illnesses (Focus on initial presentation and acute management)
• 6. Shock States:
o All Types of Shock: Hypovolemic, Cardiogenic, Septic, Anaphylactic, Neurogenic, Obstructive.
o Pathophysiology, Clinical Manifestations (stages), and Management: Fluid resuscitation,
vasopressors, inotropes, oxygen, managing underlying cause.
o Sepsis and Septic Shock: Early recognition (SIRS, SOFA), sepsis bundles, lactate, targeted
interventions.
• 7. Acute Respiratory Failure and Mechanical Ventilation:
o Types of Respiratory Failure: Hypoxemic vs. Hypercapnic.
o Acute Respiratory Distress Syndrome (ARDS): Pathophysiology, clinical presentation,
diagnostic criteria, ventilatory strategies (low tidal volume, PEEP), proning.
o Mechanical Ventilation: Indications, basic modes (AC, SIMV, CPAP/PS), ventilator settings
(FiO2, VT, RR, PEEP), common alarms (high/low pressure), nursing care for the ventilated
patient (VAP prevention, suctioning, sedation).
o Non-invasive Ventilation (NIV): BiPAP, CPAP.
o Airway Management: Endotracheal intubation (nursing role), tracheostomy care, complications
of artificial airways.
• 8. Acute Coronary Syndromes (ACS) and Cardiac Emergencies:
o Unstable Angina, NSTEMI, STEMI: Differentiating factors, pathophysiology, clinical
presentation, diagnostic tests (ECG changes, cardiac enzymes), immediate management
(MONA, fibrinolytics, PCI), complications (dysrhythmias, heart failure, cardiogenic shock).
o Cardiac Dysrhythmias (Advanced): Recognition and immediate management of life-
threatening arrhythmias (VT, VF, Asystole, Bradycardia, Tachycardia), ACLS algorithms (basic
principles).
o Heart Failure (Acute Exacerbation): Acute decompensated heart failure, cardiogenic shock,
management (diuretics, vasodilators, inotropes, IABP, VADs - basic understanding).
o Hypertensive Crisis/Emergency: Recognition, signs of end-organ damage, immediate
management.
• 9. Acute Neurological Conditions:
o Increased Intracranial Pressure (ICP): Causes, signs and symptoms, monitoring, nursing
interventions to reduce ICP.
o Stroke (Acute Management): Ischemic vs. Hemorrhagic, rapid assessment, thrombolytic
therapy (tPA), endovascular procedures, nursing care for acute stroke.
o Traumatic Brain Injury (TBI): Types of head injuries (concussion, contusion, hematomas),
monitoring, management.
o Seizures and Status Epilepticus: Management of active seizures, pharmacological
interventions, patient safety.
III. Critical Care Procedures & Diagnostics
• 10. Interpretation of Diagnostic Studies:
o Advanced interpretation of chest x-rays (e.g., ARDS, pneumothorax).
o CT/MRI findings relevant to critical illness.
o Laboratory values critical to ICU management (e.g., lactate, troponin, BNP, D-dimer,
coagulation studies, renal/liver function tests).
• 11. Management of Specialized Equipment & Procedures:
o Chest Tubes: Indications, maintenance, troubleshooting complications.

, o Temporary Pacing (transcutaneous, transvenous).
o Defibrillation and Cardioversion.
Question 1. What is the primary focus of critical care nursing philosophy?
A) Promoting patient independence
B) Providing holistic, patient-centered care to critically ill patients
C) Managing chronic illnesses
D) Emphasizing outpatient care
Answer: B
Explanation: Critical care nursing philosophy centers on providing holistic, patient-centered care aimed at
