CBM Nutritional Support for Burns 5

Question 1

What percentage of total calories from fat is typically recommended in burn patient enteral formulas to avoid immunosuppression from excessive lipid intake?

Accepted Answer

15–30%

Answer

Fat should generally comprise 15–30% of total calories in burn nutrition formulas; higher fat intake, particularly from omega-6 lipids, can impair immune function through prostaglandin-mediated immunosuppression.

Question 2

Which pharmacological agent combined with nutritional support has shown evidence of reducing hypermetabolism and improving muscle protein synthesis in adult burn patients?

Accepted Answer

Propranolol

Answer

Propranolol, a non-selective beta-blocker, reduces the catecholamine-driven hypermetabolic response in burns, decreasing resting heart rate and attenuating muscle protein catabolism when used alongside nutrition support.

Question 3

A burn dietitian notes a patient's respiratory quotient (RQ) from indirect calorimetry is 1.2. What does this indicate about the current feeding regimen?

Accepted Answer

Overfeeding with excessive carbohydrate is occurring

Answer

An RQ above 1.0 indicates net lipogenesis from carbohydrate overfeeding; the feeding regimen should be adjusted to reduce carbohydrate load and total calories.

Question 4

Which enteral formula characteristic is most appropriate for a burn patient with concurrent acute respiratory distress syndrome (ARDS)?

Accepted Answer

High-fat, low-carbohydrate formula to minimize CO2 production

Answer

High-fat, low-carbohydrate formulas reduce CO2 production by lowering the respiratory quotient, which is beneficial in ARDS patients who already have impaired CO2 clearance.

Question 5

When should the nutrition plan for a burn patient be formally reassessed according to best practice?

Accepted Answer

Every 7–14 days or with significant clinical changes such as sepsis or surgery

Answer

Burn patient nutrition plans should be formally reassessed every 7–14 days and whenever major clinical changes occur (e.g., sepsis, surgical procedures) because metabolic needs shift throughout recovery phases.
