Question

1) A parenteral nutrition formula calls for 400 mg of P (AW = 31). How many milliliters of a potassium phosphate injection containing 2.1 mmol/mL phosphate should be used?

2) A 5 ft female patient, formerly weighing 121 lb, has lost 20 lb in the past 4 weeks and will require IV nutrition prior to a planned major surgery. Her doctor calculated a nutritional plan based on her ideal weight (110 lb). How many total kilocalories will this patient receive if the nutritional plan designed for her includes 500 mL of 10% fat emulsion, 1000 mL dextrose 20%, and the protein requirement is 0.75 g/kg/day?

Please show how you got the answer

Answer 1

Solution 1 Parenteral nutrition Formula = 400mg Potassium phosphate injection contains = 2.1 mmol/ml and the Anatomic weight) = 31. So, 31x2.1= 65.1 mmol/mi Therefor. 4oong = 65.10 = 6.144 mL 6.144 mL Solution 2 : weight of patient = 121 lb weight lost 20 lb in 4 weeks SO 500mL X 1.1 kcal/mL (Soome of 10% fat) = 550 kcal. Therefore = looomLx 200 x 3.4 kcal = 6BO kcal Toombe 0.75g x 1kg x 110.16 x 4 kcal = 150 kcal kg 2.2 lb " So, the total kcal will be a 550 kcal + 680 kcal + 150 kcal = 1380 kal. LooomL dextrose 204., it means. 209m 7 Protein requirement = 0.75g/kg/day.
