Question 42 of 46

Yes, that is correct. To calculate this, you need to remember that a 3% solution is equivalent to 30 mg/ml.

Next, multiply 30 mg/ml times 1.8 (the amount of ml. of solution in a cartridge) to get 54 mg of mepivacaine per cartridge.

Then divide 240 mg. (determined in the previous question - remember that the MRD for 3% mepivacaine is 2.0 mg/lb., multiplied by a 120 lb. healthy adult) by 54 mg to equal 4.4 cartridges.
