Question

Lidocaine of 2% is prescribed for a 13-lb beagle at a dose of 2 mg/kg IV. How many milliliters will you deliver?

1. 0.59 mL
2. 0.84 mL
3. 1.07 mL
4. 1.42 mL

Answer 1

To deliver the prescribed dose of 2% lidocaine to a 13-lb beagle, you would need to deliver 0.59 mL of the solution.

Step-by-step explanation:

To calculate the amount of lidocaine to deliver to a 13-lb beagle, you need to convert the weight from pounds to kilograms. 13 lbs is approximately 5.9 kg. Then, you multiply the weight in kilograms by the prescribed dose of 2 mg/kg to find the total dose needed, which is 11.8 mg. Next, you need to convert milligrams to milliliters using the concentration of the lidocaine solution. A 2% lidocaine solution means that there are 2 grams of lidocaine in 100 mL. So, a 2% solution contains 20 mg of lidocaine per milliliter. To find the volume of the lidocaine solution to deliver, divide the total dose by the concentration. In this case, you would divide 11.8 mg by 20 mg/mL, which gives you 0.59 mL.
