NCLEX RN Practice Question

Smoking cessation has the greatest impact on reducing the risk of CVD (cardiovascular disease). Smoking damages blood vessels, increases blood pressure, reduces oxygen in the blood, and contributes to clot formation, all of which significantly raise the risk of heart attacks and strokes. Encouraging physical activity, adopting a healthy diet, and managing stress are essential components of overall cardiovascular health, but smoking cessation provides the most immediate and profound reduction in risk. Promoting stress management and encouraging physical activity are important, but their effects are gradual and supplementary compared to eliminating tobacco use.
