For a client with emphysema, which lifestyle change would most benefit lung function?

Stopping smoking is the most beneficial lifestyle change for a client with emphysema because smoking is the primary cause of this condition and significantly contributes to its progression. By quitting smoking, the client can help slow down the deterioration of lung function, reduce inflammation, and diminish further exposure to harmful irritants. This change provides immediate and long-term health benefits, as it allows the lungs to begin to heal and improves overall respiratory function.

In contrast, increased high-intensity exercise might be counterproductive for someone with emphysema, as their lung function is already compromised, and excessive exertion could lead to increased dyspnea and fatigue. A high-fat diet may not specifically improve lung function and could be detrimental to overall health, including cardiovascular status. While resting is important for everyone, excessive resting to prevent exhaustion can lead to deconditioning, which may further impair lung function and overall endurance. Maintaining an active lifestyle within safe limits is crucial for those with respiratory conditions.
