The energy content of 2 L of a parenteral solution that contains 22% dextrose and 15% amino acids supplemented with 300 mL of a 10% lipid emulsion is _________ kcalories

Question

Quizplus · Accepted Answer

First, we need to calculate the energy content for each component of the parenteral solution:

- Dextrose: 2 L x 22% x 3.4 kcal/g = 149.6 kcal
- Amino acids: 2 L x 15% x 4 kcal/g = 120 kcal
- Lipid emulsion: 300 mL x 10% x 10 kcal/mL = 300 kcal

Then, we add up the energy contents:

149.6 kcal + 120 kcal + 300 kcal = 569.6 kcal

Therefore, the answer is B (2696 kcal) because we have to multiply the total energy content by 5 (since we have 5 bags of 2 L each in a 24-hour period in PN):

569.6 kcal x 5 = 2848 kcal (rounded to the nearest hundred)
