What lifestyle change should a nurse recommend to improve cholesterol levels?

Smoking cessation is a crucial lifestyle change that can significantly improve cholesterol levels and overall cardiovascular health. Smoking has been shown to lower levels of high-density lipoprotein (HDL) cholesterol, which is known as the "good" cholesterol that helps remove low-density lipoprotein (LDL) cholesterol from the bloodstream. By quitting smoking, individuals can improve their HDL levels, thus promoting better cholesterol profiles. Furthermore, smoking cessation contributes to overall heart health by reducing the risk of atherosclerosis and improving blood circulation.

While other options may seem beneficial, they don't align as directly with impactful changes for improving cholesterol. For instance, limiting exercise to the weekends may not provide sufficient physical activity for optimal cardiovascular health, nor does a diet high in polysaturated fats specifically target cholesterol management. Weight lifting, while beneficial for overall fitness and muscle strength, may not have the same immediate effects on cholesterol levels compared to the direct impact of quitting smoking. Thus, smoking cessation stands out as the most effective recommendation for improving cholesterol levels.
