Critical Care NUR 283 Test 1 2026/2027 | 100+ Questions & Answers | Chest Tubes, ACS, COPD, ARDS & Ventilators

This comprehensive Critical Care NUR 283 Test 1 2026/2027 study guide contains 100+ exam questions, answers, and clinical illustrations across 23 pages, with concentrated coverage of respiratory and cardiovascular critical care nursing. The document begins with identification of the major components of a chest drainage system, including the suction regulator, water-seal chamber, air-leak monitoring system, collection chamber, and suction monitor bellow. It then reviews ECG rhythm recognition, including atrial fibrillation, atrial fibrillation with rapid ventricular response, sinus bradycardia, sinus tachycardia, and normal sinus rhythm, alongside therapeutic drug levels for medications such as theophylline and digoxin. A major portion of the material focuses on respiratory assessment and acute pulmonary disorders. Students compare characteristic findings associated with pneumonia, COPD, asthma, pulmonary embolism, pulmonary edema/ARDS, pleural effusion, pneumothorax, hemothorax, empyema, and lung cancer. The document also reviews COPD arterial blood gas patterns, oxygenation, FEV1 testing, breath sounds, sputum characteristics, hypoxemia, hemoptysis, tracheal deviation, and other assessment findings used to differentiate respiratory conditions. Detailed attention is given to chest tubes and pleural drainage, including normal and abnormal bubbling, troubleshooting air leaks, wet-suction systems, tube obstruction, accidental disconnection or removal, subcutaneous emphysema/crepitus, emergency dressing considerations, provider notification, and anticipated chest radiography. The illustrated opening page specifically labels the components of a chest drainage unit, making the resource useful for students who need both visual recognition and question-based review of chest-tube management. The cardiovascular section covers hypertension, hypertensive crisis, hypertensive emergency versus urgency, orthostatic hypotension, coronary artery disease, angina, acute coronary syndrome, NSTEMI, STEMI, and atrial fibrillation. Students review modifiable and nonmodifiable CAD risk factors, atypical ischemic presentations, nitroglycerin precautions, troponin and ECG findings, coronary angiography, PCI, balloon angioplasty, thrombolytic therapy, CABG, cardiac catheterization preparation, door-to-balloon concepts, and emergency treatment priorities. It also distinguishes management approaches for stable and unstable atrial fibrillation, chronic AFib, and symptomatic bradycardia. The later sections provide high-yield review of tuberculosis, pulmonary embolism, acute respiratory distress syndrome, mechanical ventilation, and airway management. Topics include active versus latent TB, airborne precautions, AFB sputum testing, directly observed therapy, ARDS causes and exudative, proliferative, and fibrotic phases, P/F-ratio severity categories, ventilator-associated pneumonia prevention, and endotracheal-tube placement verification. Mechanical ventilation questions cover assist-control (AC), SIMV and spontaneous modes, spontaneous breathing trials, high- and low-pressure ventilator alarms, rapid shallow breathing index (RSBI), electrolyte considerations, and clinical criteria for ventilator weaning and extubation. The material also includes the ABCDEF bundle, addressing awakening and spontaneous breathing trial coordination, delirium assessment and management, early mobility, and family engagement. These concepts place the study guide within the broader framework of evidence-based ICU nursing and liberation from mechanical ventilation. The overall subject coverage corresponds well with established critical-care references such as Urden, Stacy & Lough's Critical Care Nursing: Diagnosis and Management and AACN's Essentials of Critical Care Nursing. Because emergency cardiovascular, respiratory, ventilator, and medication recommendations can change, students should cross-check clinical details against their current course materials and current professional guidelines. Relevant Students: This document is particularly relevant to NUR 283 students, Critical Care Nursing students, ADN and BSN nursing students, ICU nursing students, advanced medical-surgical nursing students, respiratory critical-care students, nursing students preparing for cardiovascular and pulmonary exams, and learners reviewing chest tubes, ACS, COPD, ARDS, mechanical ventilation, TB, pulmonary embolism, pneumothorax, hypertension, ECG rhythms, and ventilator weaning. The uploaded document clearly identifies NUR 283 as the course code but does not name a university, so no unsupported institution has been attributed to it.
