Nitrogen to caloric ratio in total parenteral nutrition is:

1 gm of N2: 150 non protein calories

1 gm of N2: 100 non protein calories

1.25 gm of N2: 100 non protein calories

1.25 gm of K: 150 non protein calories

High-Yield Explanation

Parenteral formulas usually deliver 75-150 non protein carbohydrate kcal per gram of nitrogen infused, a ratio that maximizes carbohydrate and protein assimilation and minimizes metabolic complications (aminoaciduria, hyperglycemia, and hepatic glycogenesis).
