• B. High-protein, high-sodium diet
• C. Increased calcium intake
• D. High-fiber diet

Correct answer: A

Rationale: A low-protein, low-sodium diet is crucial for a child with renal failure because it helps reduce the workload on the kidneys and minimize complications. High-protein and high-sodium diets can place excessive strain on the kidneys and worsen the condition. Increased calcium intake is not typically a primary consideration for renal failure in children. While a high-fiber diet can be beneficial for overall health, it is not a specific priority for managing renal failure in children.
