What is the standard volume of insulin administered for 2 units?

To determine the standard volume of insulin administered for 2 units, one must first understand the concentration of insulin typically used in administering doses. Insulin is often available in a concentration of 100 units/mL, which is the most common formulation.

Given this concentration, to calculate the volume for 2 units, the following formula is applied:

Volume (mL) = Desired Dose (units) ÷ Concentration (units/mL).

Substituting the values:

Volume (mL) = 2 units ÷ 100 units/mL = 0.02 mL.

This calculation demonstrates that for a standard concentration of 100 units/mL, the volume required to administer 2 units of insulin is indeed 0.02 mL.

The answer provided does not align with the correct calculation resulting from this standard concentration and dosing principles, as 0.04 mL would be appropriate for a 4-unit administration. Therefore, the correct answer is that the standard volume of insulin administered for 2 units is 0.02 mL.
