A nurse is providing a community education session about the risk factors for chronic renal failure. Which lifestyle factor should the nurse emphasize as a modifiable risk factor for kidney disease?

A. Incorrect. While physical activity is essential for overall health, the client's fatigue may be related to anemia, not lack of physical activity.

B. Correct. Fatigue and lethargy are common symptoms of anemia, which is a common complication of chronic renal failure. Iron supplements can help address anemia-related fatigue.

C. Incorrect. Increasing protein intake may not directly address the underlying cause of the client's fatigue, which is likely anemia.

D. Incorrect. Caffeine-containing beverages can contribute to fluid overload and hypertension in chronic renal failure and are not a suitable intervention for addressing fatigue.

A. Incorrect. Applying a heating pad may provide temporary relief for muscle cramps, but it does not address the underlying cause.

B. Correct. Muscle cramps in clients with chronic renal failure can be caused by dehydration and electrolyte imbalances. Encouraging the client to increase fluid intake can help alleviate muscle cramps and maintain adequate hydration.

C. Incorrect. While calcium supplements may be prescribed in certain situations, they are not the first-line intervention for muscle cramps in chronic renal failure.

D. Incorrect. Educating the client about potassium-rich foods is important for managing potassium levels, but it is not the priority in this situation. Muscle cramps are more likely related to fluid and electrolyte imbalances rather than potassium intake.
