A nurse is assessing a client who has COPD and experienced recent weight loss. Which of the following findings should the nurse report provider immediately?

A. A barrel chest: A barrel-shaped chest is a common structural change in clients with long-standing COPD. While it reflects chronic disease, it is not an acute change requiring immediate provider notification. B. Coughing and wheezing after eating: This may indicate mild aspiration or gastroesophageal reflux, which should be monitored and addressed, but it is not immediately life-threatening if the client remains stable. C. Abdominal bloating: Abdominal bloating can occur due to air swallowing or gastrointestinal changes in COPD, but it is not an urgent concern unless accompanied by severe pain, distention, or other acute symptoms. D. A drop in oxygen saturation to 91% while eating: A sudden decrease in oxygen saturation indicates hypoxemia and potential respiratory compromise, especially in a client with COPD. This acute change requires immediate provider notification and possible intervention, making it the highest priority finding.
