A young man weighing 65 kg was admitted to the hospital with severe burns in a severe catabolic state. An individual in this state requires 40 kcal per kg body weight per day, 1 gm of protein/kg body weight/day. This young man was given a solution containing 20% glucose and 4.25% protein. If 3000 ml of solution in infused per day:
Calories are calculated by catabolism of glucose (not proteins).
Glucose:

Amount of glucose in 20% glucose in 3000 ml of solution: 3000 x 20/100 = 600 gms
1 gm glucose on catabolism produces: 4.2 kcal
600 gms of glucose would produce: 600 x 4.2 = 2520 kcal

Protein:

Percentage of protein in fluid: 4.25%
Percentage of protein in 3000 ml of fluid: 3000 x 4.25/100 = 127.5 gms
Calories required for the patient: 40x65 = 2600 kcal
Proteins required for the patient: 2 x65 = 130 gms
The patient would not be getting sufficient protein
The calories supplied would be inadequate
Both protein and calories would be adequate
Too much protein is being infused
