A nurse is collecting data on a client who has COPD. Which of the following findings should the nurse expect?

A. Pleural friction rub: A pleural friction rub is a grating sound caused by inflamed pleural surfaces rubbing together, usually associated with pleuritis or pneumonia. It is not a common finding in chronic obstructive pulmonary disease. B. Spoon nails: Spoon-shaped nails (koilonychia) are typically associated with iron-deficiency anemia, not COPD. They are unrelated to the chronic pulmonary changes seen in this condition. C. Peripheral edema: Peripheral edema may occur in late-stage COPD with cor pulmonale due to right-sided heart failure. However, it is not an expected finding in all clients with COPD and usually develops secondary to disease progression. D. Barrel chest: A barrel-shaped chest is a classic physical finding in COPD due to chronic hyperinflation of the lungs. The increased anterior-posterior diameter results from air trapping and loss of lung elasticity, making it a hallmark sign of the disease.
