What is the recommended volume of insulin for administering 2 units?

To determine the correct volume of insulin to administer 2 units, it's important to understand the concentration of the insulin preparation. Most commonly used insulin, particularly U-100 insulin, has a concentration of 100 units per milliliter. This means that for every milliliter (mL) of insulin, there are 100 units.

To calculate the volume needed for 2 units of U-100 insulin, you would set up the calculation as follows:

• Since there are 100 units in 1 mL, the volume needed for 1 unit is 0.01 mL (because 1 mL / 100 units = 0.01 mL/unit).

• Therefore, to find the volume for 2 units, you multiply the volume for 1 unit (0.01 mL) by 2.

This leads to the calculation:

0.01 mL/unit × 2 units = 0.02 mL.

Thus, the correct volume to administer 2 units of insulin is 0.02 mL, making this the accurate choice for those familiar with the standard concentration of insulin. Understanding this calculation is crucial for safe administration, emphasizing the need to properly convert units to volume based on the specific
