How many units of insulin are required if a student’s current glucose level is 230 mg/dL with the corrective equation (Current glucose - 140) / 30?

To determine the correct amount of insulin required based on the provided glucose level and the corrective equation, we will first need to plug the current glucose level into the equation provided.

The equation is structured as follows: (Current glucose - 140) / 30. Here, the current glucose level is 230 mg/dL.

First, subtract 140 from the current glucose level of 230 mg/dL:

230 - 140 = 90

Now, take that result and divide it by 30:

90 / 30 = 3

Thus, using the corrective equation, the student would require 3 units of insulin. This understanding aligns directly with the correct answer choice, which corresponds to the calculated result.

Using the equation effectively allows for a clear determination of how much insulin is necessary based on the difference from a target glucose level, providing a safe and systematic approach to insulin administration.
