For the PN order described as 2400 mL with 300 grams dextrose and 90 grams protein plus 225 mL of 20% IVFE, what is the total caloric content, protein, fat, and final volume?

For the PN order described as 2400 mL with 300 grams dextrose and 90 grams protein plus 225 mL of 20% IVFE, what is the total caloric content, protein, fat, and final volume?

• A. 1830 kcal, 90 grams protein, 40 grams fat, 2625 mL
• B. 2010 kcal, 90 grams protein, 40 grams fat, 2400 mL
• C. 1830 kcal, 90 grams protein, 45 grams fat, 2625 mL
• D. 1470 kcal, 90 grams protein, 45 grams fat, 2400 mL

Answer: (C)

Calculating PN content uses standard energy densities for each component: carbohydrate provides about 3.4 kcal per gram, protein 4 kcal per gram, and fat in PN emulsions delivers about 10 kcal per gram. The fat in the IVFE is found from the volume and percent fat: 225 mL × 0.20 = 45 g fat, which yields 450 kcal (45 g × 10 kcal/g). The dextrose 300 g contributes 300 × 3.4 = 1020 kcal. Protein at 90 g provides 90 × 4 = 360 kcal. Add them: 1020 + 360 + 450 = 1830 kcal. The final volume is the base PN volume plus the IVFE volume: 2400 mL + 225 mL = 2625 mL. So you get 1830 kcal, 90 g protein, 45 g fat, and 2625 mL.

So you get 1830 kcal, 90 g protein, 45 g fat, and 2625 mL.
