Boston Frank · Answer 1

Option B. 9 ml.

Step-by-step explanation:

Recommended dose of a drug = 5 mg/kg body weight.

weight of the cat = 8 lb

1 lb = 0.4536 kg.

8 lb = 0.4536 * 8 = 3.6288 kg. ≈ 3.6 kg

A solution contains a concentration of 2 mg/ml

so recommended dose for 3.63 kg = 5mg * 3.6 = 18 mg

∵ 1 ml. contains a concentration = 2 mg

∴ for 18 mg concentration dose will be = 18/2 = 9 ml

9 ml of the solution should be given to a cat.

Option B. 9 ml.
