A 12 pound DSH is presented to your hospital for a dental cleaning. The attending veterinarian has asked you to treat 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?

1 pound is approximately 0.453592 kilograms. So, a 12 pound cat would weigh.

12 pounds * 0.453592 kg/pound = 5.4431 kg

we calculate the total dosage required in milligrams (mg) using the recommended dosage of 4 mg/kg.

5.4431 kg * 4 mg/kg 

= 21.7724 mg.

Now we need to calculate the volume of Propofol to draw up. The concentration of Propofol is given as 10 mg/ml, which means each milliliter contains 10 mg of Propofol.

To find out how many milliliters contain the required 21.7724 mg of Propofol, we divide the total dosage by the concentration:

21.7724 mg / 10 mg/ml = 2.17724 ml

Since we can not measure out decimals precisely in a syringe, we'd round to the nearest tenth of a milliliter. Therefore, you will draw up 2.2 ml of Propofol in the syringe to administer to the cat.
