How is the correction dose calculated?

(blood glucose now)+(target blood glucose) / correction factor
(target blood glucose)-(blood glucose now) * correction factor
(blood glucose now)-(target blood glucose) / correction factor
(blood glucose now) / (target blood glucose + correction factor)

The correct answer is: (blood glucose now)-(target blood glucose) / correction factor

The correction dose is determined by subtracting the target blood glucose level from the current blood glucose level and then dividing that difference by the correction factor. Option A adds the target and current blood glucose levels before dividing by the correction factor, which would result in an incorrect calculation. Option B subtracts the target blood glucose level from the current blood glucose level and then multiplies that difference by the correction factor, which would also result in an incorrect calculation. Option D divides the current blood glucose level by the sum of the target blood glucose and correction factor, which is not the correct calculation method for determining the correction dose. Therefore, option C is the correct method for calculating the correction dose.
