Question 1

Which formula is commonly used to estimate caloric needs in burn patients based on body weight and percent TBSA burned?

Accepted Answer

Curreri formula

Answer

The Curreri formula estimates caloric needs by calculating 25 kcal/kg/day plus 40 kcal per percent TBSA burned.

Question 2

Which route of nutrition is preferred for burn patients when the gastrointestinal tract is functional?

Accepted Answer

Enteral nutrition via nasogastric tube

Answer

Enteral nutrition is preferred in burn patients because it maintains gut integrity, reduces bacterial translocation, and carries fewer complications than parenteral nutrition.

Question 3

Which macronutrient has significantly increased requirements in burn patients due to catabolism and wound healing demands?

Accepted Answer

Protein

Answer

Burn patients require 1.5–3 g/kg/day of protein due to massive catabolism, wound healing demands, and nitrogen losses from wound exudate.

Question 4

Which micronutrient is commonly supplemented in burn patients to support collagen synthesis and immune function?

Accepted Answer

Vitamin C

Answer

Vitamin C supports collagen synthesis, antioxidant defense, and immune function — all critical for wound healing in burn patients.

Question 5

What metabolic complication is most characteristic of the hypermetabolic stress response in severe burn patients?

Accepted Answer

Hyperglycemia

Answer

Stress hormones (catecholamines, cortisol, glucagon) promote gluconeogenesis and insulin resistance, causing hyperglycemia in burn patients.
