Tidal volume for ARDS (6 mL/kg PBW) with PBW = 75 kg equals approximately?

In ARDS, lung-protective ventilation uses a low tidal volume, about 6 mL per kg of predicted body weight. With PBW = 75 kg, multiply 6 by 75 to get 450 mL, which is the appropriate tidal volume. The other options would correspond to 4, 8, or 10 mL/kg (300, 600, or 750 mL), outside the recommended range and less protective.
