Thiopental is a barbiturate used to induce anesthesia. once reconstituted it is a 2% solution. the attending veterinarian asks you to induce a 27 kg dog with a dosage of 10 mg/kg. how many milligrams do you need, and how many milliliters will you draw up into the syringe?

13.5 mL of solution.

Explanation:

Given:

the solution is of 2% concentration.

The dosage required is 10mg/kg

The weight of dog is 27 kg

Solution:

The mass of  barbiturate required for the 27 kg dog = 27 X 10 mg = 270 mg

As the solution is 2%, so there is 2g of  barbiturate is dissolved in 100mL of solution

The mass of  barbiturate required = 0.270 g

For 2 g we will need 100mL of solution

For 1 g we will need = 50mL of solution

for 0.270g we will need = 50 X 0.270 mL of solution = 13.5 mL of solution.
