This document provides a comprehensive and in-depth collection of over 350 exam-style questions and verified answers for the HealthStream Critical Care Exam (2026). It covers essential ICU topics including cardiac emergencies, respiratory failure, sepsis management, hemodynamic monitoring, pharmacology, and advanced nursing interventions. Based on the full content (18 pages ), the material is structured in a detailed Q&A format reflecting real clinical and certification exam scenarios. Early sections (pages 1–4) focus on acute conditions such as cardiac tamponade, third-degree heart block, spinal cord injury management, chest tube assessment, and CRRT decision-making models. Mid-sections provide extensive coverage of cardiovascular disorders including heart failure (right vs left), myocardial infarction (ST elevation, ECG leads), arrhythmias (atrial fibrillation, PSVT), and pharmacologic treatments such as digoxin, nitroglycerin, adenosine, and vasopressors. Later sections explore respiratory and critical care emergencies including ARDS (as highlighted by ground-glass opacities and hypoxia on page 15), mechanical ventilation complications (e.g., PEEP-induced hypotension), pulmonary embolism, and advanced ICU monitoring (CVP, preload, cardiac output). The document also includes medication calculations, endocrine emergencies (Addisonian crisis, thyroid storm), and neurological conditions such as Guillain-Barré syndrome. This resource aligns closely with standard textbooks such as AACN Essentials of Critical Care Nursing and current AHA critical care guidelines. It is particularly valuable for mastering both theoretical knowledge and high-level clinical reasoning required in ICU and emergency care settings. This document is highly relevant for courses and programs such as: Critical Care Nursing Intensive Care Unit (ICU) Training Medical-Surgical Nursing Emergency Nursing Advanced Clinical Practice It is especially suitable for: ICU nurses and nursing students NCLEX and critical care certification candidates Emergency and trauma care professionals Healthcare providers managing critically ill patients Keywords: HealthStream test exam, ICU nursing questions, cardiac tamponade ICU, sepsis management nursing, ARDS respiratory failure, mechanical ventilation PEEP, central venous pressure CVP, myocardial infarction ECG leads, atrial fibrillation risk factors, digoxin administration nursing, nitroglycerin action angina, CRRT nursing care, medication dosage calculations nursing, Addisonian crisis treatment, Guillain Barre syndrome ICU, critical care nursing exam prep
