A1.2–2.0 g/kg/day
B0.6–0.8 g/kg/day
C2.5–3.0 g/kg/day
D0.8–1.0 g/kg/day

✓ Correct answer: A. 1.2–2.0 g/kg/day Current ASPEN/SCCM guidelines recommend 1.2–2.0 g/kg/day of protein for most critically ill patients to attenuate lean body mass loss and support recovery. The RDA of 0.8 g/kg is for healthy adults and is insufficient in critical illness.
