Question

An 80 kg patient needs 2000 kcal, 150 g prot. How would you

write their PN Rx? Assume patient has average fat needs and your
facility uses 20%IL. Show your math.

Answer 1

To write the PN Rx for the patient, we need to determine the amounts of each component (fats, proteins, carbohydrates) that will provide the required 2000 kcal and 150 g of protein. Based on the information provided, the recommended amount of fat is 65 g for a 2000 Cal daily diet. The percentage of calories supplied by this amount of fat would be approximately 29.575%.

Step-by-step explanation:

To write the PN Rx for the patient, we need to determine the amounts of each component (fats, proteins, carbohydrates) that will provide the required 2000 kcal and 150 g of protein. Let's assume the patient's fat needs are average and the facility uses 20% Intralipid (IL). Based on the information provided, the recommended amount of fat is 65 g for a 2000 Cal daily diet. To calculate the percentage of calories supplied by this amount of fat, we can use the average number of Calories for fat, which is 9.1 Calories/g.

First, we calculate the total number of Calories provided by the fat:

Total Calories from fat = 65 g * 9.1 Calories/g = 591.5 Calories

Next, we calculate the percentage of calories supplied by the fat:

Percentage of calories from fat = (Calories from fat / Total calories) * 100

= (591.5 / 2000) * 100
= 29.575%

Therefore, approximately 29.575% of the calories in the patient's 2000 Cal diet would be supplied by 65 g of fat.
