VD_anat for a 60 kg patient equals 2.2 mL/kg. What is VD_anat in mL?

Anatomical dead space volume is estimated by multiplying body weight by a per-kilogram dead-space value. Here, the per-kilogram value is 2.2 mL/kg. So for a 60 kg patient: 60 × 2.2 = 132 mL. Therefore, VD_anat is 132 mL. The other options reflect different per-kilogram values: 120 mL would come from 60 × 2.0, 144 mL from 60 × 2.4, and 156 mL from 60 × 2.6, but the given value is 2.2 mL/kg, so 132 mL is correct.
