Which of the following is NOT part of the renal disease diet?

• A. Fluid restriction
• B. Low sodium
• C. High potassium
• D. High calcium

Answer: (C)

The main idea is that a renal diet is designed to limit minerals and fluids the kidneys can struggle to manage. Potassium is a key one because damaged kidneys can’t excrete excess potassium well, which can raise the risk of dangerous heart rhythms. So a high potassium intake is avoided in renal disease. In contrast, fluid restriction helps control edema and blood pressure when urine output is reduced, and low sodium helps with fluid balance and hypertension. Calcium management is more nuanced and not universally defined as “high calcium” as a standard part of the renal diet; it’s guided by bone-mineral needs and phosphorus control, often with individual adjustments. Therefore, the option describing a high-potassium diet is the one that does not fit renal-disease dietary guidelines.
