A nurse is providing an educational session to colleagues on the unit regarding COPD. Which of the following options would the nurse provide regarding associated risks of COPD?

The clinical scenario focuses on identifying the systemic and localized complications associated with Chronic Obstructive Pulmonary Disease. Nurses must apply knowledge of respiratory pathophysiology, nutritional depletion, and immune vulnerability to recognize how airway obstruction leads to secondary multi-systemic health impairments. Choice A rationale . Hypermetabolism and increased work of breathing in respiratory disease elevate caloric demands, often leading to nutritional deficits. Chronic inflammation further suppresses appetite while shortness of breath interferes with the physical act of eating, resulting in poor nutritional status. Choice B rationale . Weight loss occurs as energy expenditure exceeds intake due to the high metabolic cost of labored breathing. Low oxygenation levels and systemic inflammatory cytokines can trigger cachexia, leading to a significant reduction in total body mass and fat. Choice C rationale . Impaired mucociliary clearance and chronic stasis of secretions create an ideal environment for bacterial growth. Weakened lung structures and reduced cough effectiveness significantly increase the risk of developing secondary pulmonary infections like pneumonia in these immunocompromised tissues. Choice D rationale . Systemic inflammation and chronic hypoxia contribute to skeletal muscle wasting and metabolic changes. Reduced physical activity due to dyspnea leads to disuse atrophy, while oxidative stress impairs the contractile function of both peripheral and ventilatory muscles.
