Question 1

What is the primary purpose of indirect calorimetry in burn patient care?

Accepted Answer

Determine actual resting energy expenditure

Answer

Indirect calorimetry measures oxygen consumption and CO2 production to calculate actual resting energy expenditure, enabling precise caloric goals.

Question 2

Which complication can result from overfeeding burn patients with excessive carbohydrates?

Accepted Answer

Hepatic steatosis and CO2 retention

Answer

Excess carbohydrates are converted to fat in the liver (hepatic steatosis) and produce excess CO2, worsening respiratory status in burn patients.

Question 3

Which trace element is commonly depleted in burn patients due to losses through wound exudate and is critical for wound healing?

Accepted Answer

Zinc

Answer

Zinc is lost through burn wound exudate and its deficiency impairs wound healing, immune function, and protein synthesis.

Question 4

Which medication used in burn care has been shown to reduce the hypermetabolic response and preserve lean body mass?

Accepted Answer

Oxandrolone

Answer

Oxandrolone, an anabolic steroid, promotes protein synthesis, reduces hypermetabolism, and preserves lean body mass in burn patients.

Question 5

In a burn patient with a 40% TBSA burn, how does severe protein catabolism typically manifest on laboratory evaluation?

Accepted Answer

Negative nitrogen balance

Answer

Massive protein catabolism causes negative nitrogen balance where nitrogen losses through urine and wounds exceed nitrogen intake, leading to muscle wasting.
