Patient weight in kg: Total calories = 170 + 280 = 450 calories

= 155 = 70.45 kg 181.(c) 42.58 hours.
2.2
Patient weight in kg = 155 = 70.45 kg
Dose of Aminoacid in grams: 2.2

= 1.5 x 70.45 Rate of infusion per hour in above patient:
= 105.68 gm
= 0.1 x 70.45 gm/hour
178.(a) 15.71 hours. = 7.045 gm/hour

Patient weight in kg = 140 = 63.63 kg The amount of dextrose in 1000cc D30W:
2.2
= (1000 x 30)/100= 300 gm dextrose
Total amount that should be infused in a day:
The number of hours required:
= 60 x 63.63
= 3818.18 cc = 300 = 42.58 hours
7.045
Time required infusing 2500cc:
182.(a) The number of hours required to infuse 2.4
= 2500.00 = 0.654 day = 15.71 hours liters or 2400cc solution,
3818.18
= 2400 = 7272.72 minutes = 121.21 hrs.
179.(b) 510 calories 0.33

Each gram of dextrose provides 3.4 calories or kcal. 183.(b) No, it will not make the patient sedate since
alcohol is metabolized at a rate of 20 cc/hour or
Calories provided by 500cc D30W: 0.33 cc/min which will the same rate as alcohol is
infused.
= 500 x 30 x 3.4 = 510 calories or kcal.
100 184.(c) Mr. Shroff’s TPN provides 1100 nonprotein
calories and 45% of nonprotein calories as fat,
180.(b) Each gram of dextrose provides 3.4 calories therefore one can say:
and each ml of alcohol provides 5.6 calories,
therefore the total calories provide by 1000cc 5% = 1100 x 0.45
dextrose and alcohol: = 495 calories from fat.

Energy provided by 1000cc D5W: The remaining (1100-495) 605 calories are provided
by dextrose, the maximum dextrose concentration
= 1000 x 5 x 3.4 = 170 calories. is 12.5%, and each gram of dextrose provides 3.4
100 calories:

Energy provided by 1000cc 5% alcohol: = 605 = 177.94 gm dextrose
3.4
= 1000 x 5 x 5.6 = 280 calories.
