Which indices are maintained when energy intake is adequate in dialysis PN?

• A. Hematocrit and platelets
• B. Serum albumin and anthropometrics
• C. Creatinine and BUN
• D. Vitamin D and calcium

Answer: (B)

When energy needs are met in dialysis PN, the body can spare protein and maintain nitrogen balance, which is why nutritional adequacy is best reflected by measures of protein status and body stores. Serum albumin and anthropometrics capture this: albumin serves as a indirect marker of protein sufficiency over time, and anthropometric measures (weight and body composition indicators) reflect lean mass and fat stores that are preserved with adequate energy intake. In contrast, hematocrit and platelets are more influenced by anemia management and inflammation, while creatinine and BUN reflect renal function and protein load rather than energy adequacy, and vitamin D with calcium reflect bone-mineral metabolism. Thus, serum albumin and anthropometrics are the most relevant indices for indicating adequate energy intake in dialysis PN.
