This NUR 215 Exam 4 study guide covers high-yield respiratory and stress-management concepts, including upper and lower airway anatomy, ventilation, respiration, external and internal gas exchange, diaphragm function, pulmonary function, emphysema, respiratory infections, and focused respiratory assessment. It reviews abnormal breathing patterns such as Kussmaul, Cheyne-Stokes, and Biot’s respirations, early and late manifestations of hypoxia, pediatric signs of respiratory distress, dyspnea, hypoxia versus hypoxemia, ABGs, chest X-rays, sputum cultures, pulse oximetry, and peak expiratory flow testing. The material provides detailed oxygenation nursing interventions, TCDB, incentive spirometry, aspiration precautions, oxygen delivery devices and flow rates, oxygen toxicity, home oxygen safety, and artificial airways including oropharyngeal, nasopharyngeal, endotracheal, and tracheostomy airways. It also covers stress, distress, eustress, situational, developmental, time, and anticipatory stressors, physiological and psychosocial stressors, and adaptive coping strategies.
