For ESRD, which electrolyte should be limited in the diet?

• A. Potassium
• B. Sodium
• C. Calcium
• D. Magnesium

Answer: (A)

In end-stage renal disease, the kidneys lose the ability to excrete potassium effectively, so potassium tends to accumulate in the body. High potassium levels can disrupt heart rhythm and be life-threatening, so dietary potassium is limited to reduce the risk of dangerous hyperkalemia. While sodium restriction is also common to control fluid overload and blood pressure, the electrolyte specifically limited because of impaired excretion is potassium. Calcium and magnesium are monitored and managed carefully in ESRD, but they are not the primary dietary restriction driven by the need to prevent dangerous potassium buildup. Foods high in potassium, such as bananas, potatoes, and citrus fruits, are typically limited for these patients.
