If a drug's recommended dose is 5 mg/kg, and a solution contains a concentration of 2 mg/ml of the drug, what volume of the solution should be given to a cat that weighs 8 lb.?
a. 20 ml
b. 9 ml
c. 90 ml
d. 2 ml

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.
