What is the initial Total Daily Dose (TDD) of insulin for T1DM?

0.5 U/kg/day (TBW)
1 U/kg/day (TBW)
450/TDD insulin
500/TDD

The correct answer is: 0.5 U/kg/day (TBW)

For patients with Type 1 Diabetes Mellitus (T1DM), the initial Total Daily Dose (TDD) of insulin is typically calculated based on their total body weight (TBW). The recommended starting TDD for T1DM is around 0.5 units/kg/day. This initial dose aims to provide a baseline amount of insulin to manage blood glucose levels adequately. Adjustments to the TDD can be made based on the individual patient's response to treatment, their diet, activity level, and other factors. Options B, C, and D do not reflect the standard initial TDD calculation for T1DM based on the patient's total body weight. Therefore, they are not the correct choices in this scenario.
