In older adults with CKD, which restrictions are individualized based on patient goals?

• A. Sodium, fluid, phosphate, and potassium restrictions
• B. Sodium, fluid restrictions only
• C. Protein restrictions only
• D. Carbohydrate restrictions only

Answer: (A)

Dietary limits in older adults with CKD are personalized to fit the patient’s goals while reflecting current labs, symptoms, and overall health. Managing sodium and fluids helps control blood pressure, edema, and thirst, which are common concerns in CKD. Potassium restriction becomes important when there’s a risk of hyperkalemia due to reduced kidney excretion or interactions with medications. Phosphate restriction supports bone–mineral balance and helps prevent vascular calcification, and it is often adjusted based on phosphate levels and dietary tolerance. Together, these four restrictions can be tailored to what the patient values—such as preserving appetite, maintaining energy, or avoiding symptoms—while still protecting kidney health.

Restricting only sodium and fluids omits electrolyte and mineral management that CKD often requires. Restricting protein or carbohydrates alone does not capture the multi-faceted dietary adjustments many older adults need in CKD, which commonly involve the mineral and fluid/electrolyte categories described.
