A nurse is assessing a client who has COPD. The nurse should expect the client's chest to be which of the following shapes?

Rationale: A. Kyphotic refers to an exaggerated outward curvature of the thoracic spine, not specific to COPD. B. Pigeon (pectus carinatum) is a protrusion of the sternum and is not associated with COPD. C. Funnel (pectus excavatum) is a sunken sternum and is unrelated to COPD. D. Barrel chest is common in COPD due to chronic air trapping and hyperinflation of the lungs, resulting in an increased anterior-posterior diameter of the chest.
