This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: General surgery, Subject name: Surgery
A young man weighing 65 Kg was admitted to the hospital with severe burns in a severe catabolic state. An individual in this slate requires 40 KCal per Kg body weight per day 1 gm of protein/Kg body weight/da. This young man was given a solution containing 20% glucose and 4.25% protei. If 3000 ml of solution in infused per day. 
Select and explain. 
A. The patient would not be getting sufficient protein, B. The calories supplied would be inadequate, C. Both Protein and calories would be inadequate, D. Too much protein is being infused
C: Both Protein and calories would be inadequate
Answer: C: Both Protein and calories would be inadequate 
Explanation: Calories are calculated by catabolism of glucose (not proteins) Glucose: Amount of glucose in 20% glucose in 3000 ml of solution: 3000*20/100 = 600 gms. 1 gm glucose on catabolism produces: 4.2 KCal. 600 gms of glucose would produce: 600*4.2 = 2520 KCal. Protein: Percentage of protein in fluid: 4.25% Percentage of protein in 3000ml of fluid: 3000*4.25/100= 127.5 gms. Calories required for the patient: 40*65 = 2600 KCal Proteins required for the patient: 2*65 = 130 gms. Required amount Supplied by solution Calories 2600 KCal 2520KCal Proteins 130 gms 127.5 gm Ref: Sabiston 20th edition Pgno: 119
