Question

17. The physician has ordered lidocaine \( 30 \mathrm{mg} \) for injection at a wound site. You have a vial with a label that reads, "Lidocaine \( 2 \% \) solution." How many mL will you give? (Hint:

Answer 1

To administer 30 mg of lidocaine from a 2% solution, you would give 1.500 ml.

Step-by-step explanation:

To find the amount of Lidocaine 30 mg in a 2% solution, you can use the concentration formula:

Concentration = Amount of solute / Amount of solution

Given that the solution is a 2% Lidocaine solution:

2% = 30 mg / Volume of solution

Let's solve for the volume of the solution:

Volume of solution = 30mg / 2%

First, convert the 2% into a decimal by dividing by 100:

2% = 2/100 = 0.02

Now, plug in the values:

Volume of solution = 30 /0.02

Volume of solution = 1500 ml

Therefore, to administer 30mg of Lidocaine from a 2% solution, you would need 1500 ml of the solution.

The question seems incomplete, but I suppose the question was:

"The physician has ordered lidocaine 30 mg for injection at a wound site. You have a vial with a label that reads, "Lidocaine 2% solution." How many ml will you give?"
