Question

A 12 pound DSH is presented to your hospital for a dental cleaning. The attending veterinarian has asked you to induce the cat with Propofol at a dosage of 4 mg/kg IV. The concentration of Propofol is 10 mg/ml. How many milliliters will you draw up in the syringe?

Answer 1

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

Step-by-step explanation:

The mass in kg of a 12 pound DSH is:

12 pound ×
`(0,453592kg)/(1 pound)` = 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 ×
`(4mgPropofol)/(kg)` = 21,8 mg

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

21,8 mg ×
`(1 mL)/(10 mg)` = 2,18 mL of propofol

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

I hope it helps!
