NUTR 513 Lecture Notes - Lecture 1: Heart Valve, Hematemesis, Orthopnea
Document Summary
Scientific knowledge base: respiratory physiology, respiration is the exchange of oxygen and co2 during cellular metabolism, three steps: ventilation, perfusion, diffusion, structure and function, gases move into and out of the lungs through pressure changes. Increased metabolic rate: normal in pregnancy, wound healing, and exercise, fever, conditions affecting chest wall movement, pregnancy, obesity, musculoskeletal abnormalities, trauma, neuromuscular disease, cns alterations iv. In response to metabolic acidosis: respiratory alkalosis, s&s: rapid respirations, sighing breaths, numbness and tingling of hands/feet, light-headedness, and loss of consciousness, hypoxia. Inspection: skin and mucous membrane color, general appearance, Loc, adequacy of systemic circulation, breathing patterns and chest wall movement: look for clubbed nails, palpation, percussion, auscultation, diagnostic tests. E. ) nursing diagnosis: table 40-2, p. 834, table 40-3, p. 836, table 40-5, p. 837, nursing diagnosis examples: activity intolerance, decreased co, fatigue, impaired gas exchange, impaired spontaneous ventilation.
