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 and 2 gms 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 is infused per day

**Core Concept**
Burn patients require a high caloric and protein intake to support their catabolic state, which leads to increased energy expenditure and muscle breakdown. The recommended caloric intake for severely burned patients is approximately 40 kcal/kg/day, and the protein requirement is around 2 g/kg/day.

**Why the Correct Answer is Right**
To calculate the caloric and protein intake provided by the solution, we need to calculate the total amount of glucose and protein infused per day. The solution contains 20% glucose and 4.25% protein. **Option A** is the correct choice because it correctly calculates the total caloric and protein intake provided by the solution. First, we need to calculate the total amount of glucose infused per day: 3000 ml x 20% = 600 ml of glucose. To convert this to calories, we multiply by 3.4 kcal/ml (since glucose has 3.4 kcal/ml): 600 ml x 3.4 kcal/ml = 2040 kcal. Next, we calculate the total amount of protein infused per day: 3000 ml x 4.25% = 127.5 g of protein. This exceeds the recommended 2 g/kg/day protein requirement for the patient.

**Why Each Wrong Option is Incorrect**
**Option B:** This option does not correctly calculate the caloric intake from glucose, as it only considers the amount of glucose infused (600 ml x 3 kcal/ml = 1800 kcal), ignoring the rest of the solution.

**Option C:** This option incorrectly calculates the protein intake, as it assumes the entire 3000 ml solution contains 4.25% protein, resulting in an excessive protein intake.

**Option D:** This option does not provide a calculation for the caloric or protein intake, making it an incomplete and incorrect choice.

**Clinical Pearl / High-Yield Fact**
Burn patients require a high caloric and protein intake to support their catabolic state, which can lead to muscle wasting and delayed healing. A common mnemonic to remember the caloric requirement for burned patients is "40 kcal/kg/day = 1 caloric unit per kilogram per day."

**Correct Answer:** A.

✓ Correct Answer: C. Both proteins and calories would be adequate
