Another nurse told me something the other day that I have never heard before. I tried googling it and couldn't find anything either. He said that if you are giving insulin and you aren't sure when the pt will be eating, you can divide the BS by 50% and if it is still in a save range, you can give the insulin. He says it should never drop the sugar more than 20 - 25%, but he uses 50% to be safe. So what he is saying is that if the BS is 200 and you give the ordered SS dose, the sugar would at most drop to 100 which is still safe for the pt.Has anyone ever heard this before??? I was always taught to wait until trays are on the floor.
