The volume required to provide 177.94 gm dextrose 188.(c) TPN solution should provide 55% of 1500
as a 12.5% concentration: nonprotein calories as dextrose:

= 177.94 x 100 = 1423.52cc dextrose. = 1500 x 0.55
12.5 = 825 calories as dextrose

185.(b) The cc of solution required to prepare 3% The grams of dextrose required:
amino acid solution containing 30 gm amino acid
are: = 825 = 242.64 gm dextrose
3.4
= 100 x 30 = 1000cc
3 The number of cc of dextrose 30% requires:

186.(a) 1297.78 calories = 242.67 x 100 = 808.82cc dextrose soln.

Weight in kg = 120/2.2 = 54.54 kg
Height in cm = 62 inch = 62 x 2.54 cm 189.(d) TPN solution should provide 45% of 2000
= 157.48 cm nonprotein calories as fat:

BEE = 655.1 + 9.56 x 54.54 + 1.85 x 157.48- 4.86 x 35 = 2000 x 0.45
= 900 calories as fat
= 1297.78 calories
The number of grams of fat required:
187.(d) 1172 calories.
= 900 = 100 gm fat
Total calories provided by dextrose: 9
The number of cc of 20% fat solution required:
= 1200 x 5 x 3.4 = 204 calories
100 = 100 x 100 = 500cc of 20% fat solution.
20
Calories provided by amino acid:
190.(c) 3000cc 5% amino acid.
= 1000 x 10 x 4 = 400 calories
100 Patient weight in kg = 165 = 75 kg
2.2
Calories provided by alcohol:
The number of grams of amino acid required:
= 100 x 5 x 5.6 = 28 calories
100 = 2 x 75 = 150 gm
A number of cc of 5% amino acid:
Calories provided by fat:
= 100 x 150 = 3000cc 5% amino acid solution.
= 300 x 20 x 9 = 540 calories 5
100
191.(c) 53.75 calories
Total calories provided by TPN:

= 204 + 400 + 28 + 540 = 1172 calories.
