A client on mechanical ventilation with extensive burns covering 30% of total body surface area requires nutritional support. Which of the following is the most appropriate initial intervention to address the client's increased metabolic demands?

Severe burns covering a large total body surface area trigger a profound hypermetabolic and catabolic response due to increased inflammatory mediators and stress hormones. This leads to rapid protein breakdown, muscle wasting, impaired wound healing, and increased infection risk. Clients on mechanical ventilation with major burns require early nutritional support to preserve lean body mass and support tissue repair. Enteral feeding is preferred whenever the gastrointestinal tract is functional. Rationale: A. Starting total parenteral nutrition (TPN) immediately without assessing gastrointestinal function is not the initial intervention because the gut should be used whenever possible. Parenteral nutrition is associated with higher risks of infection, metabolic complications, and loss of gut mucosal integrity. Enteral feeding is safer, more physiologic, and helps maintain intestinal barrier function. B. Initiating early enteral nutrition (EN) as soon as possible is the most appropriate intervention because it supports metabolic demands and promotes gut integrity. Early feeding reduces bacterial translocation, decreases infection risk, and improves wound healing in burn clients. It also helps counteract the hypermetabolic state by providing essential calories and protein for tissue repair. C. Providing oral diet consisting of high-calorie supplements is not appropriate for a mechanically ventilated client. These clients are often unable to safely swallow or meet nutritional needs orally due to intubation and critical illness. Oral intake is typically not feasible in the acute phase of severe burns and ventilation support. D. Delaying nutritional interventions until the client is stable and can tolerate feeding is inappropriate because early nutrition is critical in burn management. Delayed feeding worsens catabolism, increases infection risk, and impairs healing. Guidelines emphasize initiating nutrition within the first 24–48 hours if possible, rather than waiting for full clinical stability.
