CBM Nutritional Support for Burns 2

Question 1

Which vitamin is critically depleted in burn patients due to its role in collagen synthesis and antioxidant defense?

Accepted Answer

Vitamin C

Answer

Vitamin C is rapidly consumed in burn patients because it is essential for collagen synthesis and acts as a key antioxidant during the hypermetabolic stress response.

Question 2

In a 70 kg patient with a 40% TBSA burn, approximately how many grams of protein per day are recommended using standard burn nutrition guidelines?

Accepted Answer

175 g/day

Answer

Standard burn guidelines recommend approximately 1.5–2.5 g/kg/day of protein; for a 70 kg patient with major burns, ~2.5 g/kg yields approximately 175 g/day.

Question 3

What is the primary rationale for using indirect calorimetry in burn patients rather than predictive equations?

Accepted Answer

It directly measures actual resting energy expenditure

Answer

Indirect calorimetry directly measures oxygen consumption and carbon dioxide production, giving an accurate real-time measurement of resting energy expenditure in the highly variable burn hypermetabolic state.

Question 4

Which trace element supplementation is most strongly supported in burn care to promote wound healing and immune function?

Accepted Answer

Zinc

Answer

Zinc is the most extensively studied trace element in burn nutrition, supporting immune function, protein synthesis, and wound healing, and is frequently supplemented due to significant urinary losses.

Question 5

Early enteral nutrition in burn patients (within 6 hours of injury) primarily helps to prevent which complication?

Accepted Answer

Gut mucosal atrophy and bacterial translocation

Answer

Early enteral feeding maintains gut mucosal integrity, preventing villous atrophy and the translocation of intestinal bacteria that can lead to sepsis in burn patients.
