The initial protein requirements for a critically ill trauma patient weighing 70 kg are which range?

• A. 55-70 grams
• B. 105-140 grams
• C. 70-105 grams
• D. 140-175 grams

Answer: (B)

In critical illness like trauma, the body stays in a hypermetabolic, catabolic state and requires more protein to support wound healing, immune function, and maintenance of lean body mass. The recommended intake for this situation is about 1.5 to 2.0 grams of protein per kilogram of body weight per day. For a patient weighing 70 kg, that translates to roughly 105 to 140 grams of protein daily. This range best matches the initial needs in severe trauma, reflecting a shift well above maintenance levels. Lower ranges (around 0.8–1.0 g/kg/day) would underfeed the increased protein requirements during critical illness and risk more rapid muscle breakdown. Higher ranges (around 2.0–2.5 g/kg/day) are beyond typical initial targets and may not be necessary or appropriate for all patients, especially if there are renal concerns.
