Good evening, I would like to have some with these HW . you Using above answers for AAs and IVFE kcals, solve for X to calculate dextrose kcal needed after
completing all calculations:
Dextrose kcal needed:
2400kcal –
kcal from AAs –
kcal from IVFE = 1200 kcal/d of dextrose
1200 kcal/d dextrose :
kcal/g =
g dextrose
Total volume for macronutrients: (keep in mind that an additional 100 to 120 ml/d will be provided
from additives including electrolytes, parenteral multiple vitamins and trace minerals)
AAs 20%
ml + IVFE 30%
ml + dextrose 70%
ml =
ml/d
Total kcals supplied by dextrose, protein and lipids in using a final volume of 1500ml/day:
kcal from AA +
kcal from dextrose +
kcal from lipids =
kcal/d After reviewing the above, complete the following calculations:
Example 2 – Calculations: (fill in the blanks)
If using AAs 20%, solve for X:
Protein: 20g/100ml = 120g/Xml: X=
ml of AAs 20%:
120g AAs x 4kcal/g =
kcal/d from AAs
If using IVFE 20% to 30%, solve for X:
2400kcal/d x 20% =
kcal/d : 2kcal/ml =
kcal/d
2400kcal/d x 30% =
kcal/d : 3kcal/ml =
kcal/d
Which % IVFE would be the best choice with a PN formulation restricted to 1/5 L/d?
20%
or
30%
How many IVFE ml’s are needed:
IVFE 30% provides 3kcal/ml, therefore
kcal/d : 3kcal/ml =
ml of IVFE
Which is more calorically dense, IVFE 30% or dextrose 70%?
IVFE 30% provides 3 kcal/ml
Dextrose 70% provides
kcal/ml
Which one is more calorically dense? Answer:
Using above answers for AAs and IVFE kcals, solve for X to calculate dextrose kcal needed after
completing all calculations:
Dextrose kcal needed:
2400kcal –
kcal from AAs –
kcal from IVFE = 1200 kcal/d of dextrose
1200 kcal/d dextrose :
kcal/g =
g dextrose
Total volume for macronutrients: (keep in mind that an additional 100 to 120 mild will be provided Calculation of dextrose:
ml of
% dextrose yields
g and
g x 3.4 kcal/g yields _
kcal/day
Calculation of lipids:
ml of
% lipid x 2kcal/ml yields
_kcal/d (the IVFE will be piggyback infused)
Total kcals supplied by dextrose, protein and lipids in 1500ml/day:
kcal from AA +
_kcal from dextrose + _kcal from lipids =
kcal/d
Example 2:
Stock solutions used by the pharmacy for compounding PN are AAs 20%, dextrose
70%, and IVFE 30%.
The pharmacy compounds TNA solutions with an ACD.
After reviewing the above, complete the following calculations:
Example 2 – Calculations: (fill in the blanks) Case Study 2— Do Calculation for Fluid Restricted PN Formulation: Show you r work — Meeting the caloric and protein needs of the fluid—restricted patient can be challenging and, in
some cases, impossible. — AA stock solutions in 15% and 20% concentrations are available commercially. They are more expensive on a gram of protein basis compared to M 8.5% or 10% formulations, especially if the
pharmacy is purchasing 500ml containers for manual compounding as opposed to larger stock bottles of AA 15% or 20% formulations for automated compounding. The 20% M solution is
available only as a Z—L volume unit for automated compounding. — Dextrose 50% or 70% should be used for compounding PM in situations of fluid restriction. Case: A patient weighing 80kg has estimated requirements of 30 kcalfkgfday, 1.5g profkgfday, and 20-30 9% of
total kcals will be provided as IVFEs. The PM formulation volume is restricted to 1.5Lfday. #1: Stock solutions used by the pharmacy for compounding PM are AAs 10%, dextrose 70%, and IVFE
20%. —PN formulations are manually compounded without an ACD as dextrose—AA formulations After reviewing the above, complete the following calculations: 1 — Calculate: Use amounts amenable to manual compounding [fill in the blanks] Calculation of Ms: AA _% of 1000 yields g and g x 4kcallg yields kcal/day Calculation of dextrose: ml of “if. dextrose yields g and gx 3.4 kcal/g yields kcal/day
