Question

1. Jerry's FBS is 109 mg/dl Insulin dose 15 units of Lantus and 4 units of Humalog Breakfast: 2 slices Pepperidge Farm Whole Wheat Bread 8 ounces of skim milk 2 tsp. margarine 2 slices bacon two hour post meal BG 138 mg/dl Based on the above info what is Jerry's insulin to CHO ratio? 2. If Jerry wanted to add a second glass of milk with his breakfast, how much total Humalog should he take? (round to nearest whole number)

Answer 1

as per rule of 500

insilin carb ratio is 500/ total daily insulin dose

500/19

26.3 so the ratio is 1:26 means 1 unit of insulin for 26 gms of carbs

addition of second glass will give you 13.5 gms more carbs so .51 units of humalog should be added to existing 4 units

total 4. 5 units of humalog rounded down to 4 units in case of insulin administration
