Answer:

You need to draw up 2,18 mL of propofol in the syringe.

Explanation:

The mass in kg of a 12 pound DSH is:

12 pound ×[tex]\frac{0,453592kg}{1 pound}[/tex] = 5,44 kg

As the dosis you need to induce the cat is 4 mg Propofol/kg. A cat of 5,44 kg need:

5,44 kg ×[tex]\frac{4mgPropofol}{kg}[/tex] = 21,8 mg

Now, if the concentration of propofol is 10 mg/mL, 21,8 mg of Propofol are in:

21,8 mg ×[tex]\frac{1 mL}{10 mg}[/tex] = 2,18 mL of propofol

Thus, you need to draw up 2,18 mL of propofol in the syringe.

I hope it helps!
