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:
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
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
