1 Copyright 2002, Delmar, A division of Thomson Learning Chapter 15 Thorax and Lungs

2 Copyright 2002, Delmar, A division of Thomson Learning Competencies Identify the anatomic landmarks of the thorax. Describe the characteristics of the most common respiratory chief complaints. Perform inspection, palpation, percussion, and auscultation on a healthy adult and on a patient with pulmonary pathology. (continues)

3 Copyright 2002, Delmar, A division of Thomson Learning Competencies Explain the pathophysiology for abnormal findings. Document respiratory assessment findings. Describe the changes that occur in the lungs with the aging process.
