22 2 + 7 = 51 units of total insulin per day. Decrease by 10% 51 units 0.9 = 45.9 units per day round up to 46 units. 46 units 0.50 = 23 units, administer 23 units of insulin glargine once daily. 46 units 0.50 = 23 units total Insulin Lispro.

B) 15 units of insulin glargine once daily, Insulin Lispro 5 units 3 times a day with meals. Sounds like a good compromise between the long and short-acting insulin.

I feel like option B makes sense since it seems to balance the long and short-acting insulin, but I'm not entirely confident about the numbers.

I practiced a similar question where we had to switch from NPH to glargine, but I can't recall the exact ratios we used for Lispro.

I think the total daily insulin was 62 units before the change, so 10% would be about 6 units, right?

I remember we talked about reducing the total daily insulin by 10%, but I'm not sure how to calculate that exactly.

Okay, I think I've got a good strategy. I'll break this down into smaller steps, calculate the new total daily insulin, and then divide it up accordingly. Gotta stay focused and double-check my work.

Okay, let's see. I need to figure out the total daily insulin and then split it into the long-acting and short-acting components. This will take some thinking, but I think I can work it out.

Hmm, this looks like a tricky one. I'll need to carefully calculate the new insulin regimen based on the 10% decrease and the 50:50 ratio.
