What is the total Ketamine dose (in mg) required for the 12.5 lb cat at 22 mg/kg, given the weight in kilograms?

• A. 100 mg
• B. 125 mg
• C. 145 mg
• D. 110 mg

Answer: (B)

Dosing depends on body weight in kilograms times the dose per kilogram. Convert the cat’s weight to kg: 12.5 lb ÷ 2.2046 ≈ 5.67 kg. Multiply by 22 mg/kg: 5.67 × 22 ≈ 125 mg. Rounded to the nearest milligram, the total ketamine dose is 125 mg. The other numbers would require different weights that don’t match the given 12.5 lb.
