A nurse is reinforcing nutritional teaching with a client who has COPD. Which of the following statements by the patient requires further instruction?

A. I will restrict calorie intake to avoid gaining weight: Clients with COPD often have increased work of breathing and higher energy needs; excessive calorie restriction can lead to malnutrition and muscle wasting. B. I will avoid carbonated beverages: Carbonated drinks can increase bloating and dyspnea by causing gastric distention, so avoiding them is appropriate. C. I will increase my fiber intake: Higher fiber helps prevent constipation (common with reduced activity and some meds) and supports overall nutrition, so this is appropriate. D. I will use the bronchodilator before exercise: Using a bronchodilator before activity can improve airflow and exercise tolerance - this is a recommended practice.
