A nurse is reinforcing teaching with a client who has a new diagnosis of COPD. Which of the following statements by the client indicates an understanding of the teaching?

A. "I will increase my fluid intake to 1,700 milliliters per day.": While maintaining hydration is important for people with COPD, 1,700 milliliters may not be sufficient for all individuals. Fluid intake should be tailored to the patient's needs, and the client should be advised to follow specific guidelines from their provider. B. "I should do aerobic exercises once per day.": This is somewhat correct, as regular exercise is beneficial for people with COPD, but it should be individualized based on the client's current condition and limitations. However, exercise should not be the primary focus of initial teaching for someone newly diagnosed with COPD. C. "I will consume low-protein, low-calorie foods.": This is incorrect. COPD clients generally need a balanced diet with sufficient protein and calories to support respiratory function and muscle strength. A low-calorie diet may contribute to weight loss and muscle wasting, which can worsen COPD symptoms. D. "I should practice pursed-lip breathing exercises.": This is correct. Pursed-lip breathing helps to control shortness of breath, improve ventilation, and reduce the work of breathing, which is an important strategy for individuals with COPD to manage their condition.
