Your patient has been in a car accident, has multi-system organ failure, and is on a ventilator in the ICU You suspect he is highly hypermetabolic The most appropriate method of estimating energy requirements in this patient is:

Question

Quizplus · Accepted Answer

Indirect calorimetry is the most appropriate method of estimating energy requirements in a highly hypermetabolic patient. It measures oxygen consumption and carbon dioxide production to calculate energy expenditure, and is considered the gold standard for determining individualized energy needs in critically ill patients. The other options (B, C, and D) are not appropriate in this situation. Doubly labeled water is more useful for measuring average energy expenditure over a period of time, direct calorimetry is impractical in a clinical setting, and the USDA's MyPyramid website is designed for healthy individuals, not critically ill patients. Indirect calorimetry is the best method for estimating energy requirements in a hypermetabolic patient. This method measures the amount of oxygen consumed and carbon dioxide generated, and calculates energy expenditure based on these measurements. Doubly labeled water is more appropriate for estimating energy expenditure over a longer period of time, and direct calorimetry is not practical in a clinical setting. The USDA's MyPyramid website is not appropriate for estimating energy requirements in critically ill patients.
