If a student has a glucose level of 225 mg/dL, what insulin dose would be calculated using the equation (current glucose - 140) / 50?

To determine the appropriate insulin dose when a student has a glucose level of 225 mg/dL using the given formula (current glucose - 140) / 50, we can break it down step-by-step.

First, we start with the current glucose level, which is 225 mg/dL. According to the formula, we subtract 140 from this value:

225 - 140 = 85.

Next, we take the result of that subtraction and divide it by 50:

85 / 50 = 1.7.

This result indicates that the calculated insulin dose is 1.7 units. When rounding this result to one decimal place, you would typically go to the nearest half-unit. In this case, 1.7 rounds to 1.5 units.

Thus, the calculated insulin dose based on the equation indeed corresponds to the answer choice indicating 1.5 units, confirming that this is the suitable dose for the given glucose level.

This calculation is crucial for individuals managing diabetes, as it helps determine the necessary insulin administration based on current blood glucose readings, ensuring effective glucose control.
