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.

What you are asking for is the "correction factor." I have seen this used only with insulin pumps. A correction factor is how much one unit of insulin will drop blood sugar. This number is different for everyone based on how sensitive they are to insulin. This can be calculated to estimate the correction factor by using the 1500 rule. Add up the total daily insulin dose for three days in a row and average the three days, then divide 1500 by the total daily dose. Example: If 30 units of insulin is taken each day (basal and bolus doses) then the correction factor would be 50. One unit will lower blood sugar 50 points. This rule is for regular insulin and there are different rules for Humalog and Novolog. You will add this correction to the meal time dose based on the pre meal blood sugar. You only add insulin to the basal rate when the blood sugar is above the target goal. However, if the blood sugar is very low, you can use the correction to also lower the meal time dose.
This might explain it better. Bu tlike I said I have only seen this used with insulin pumps.

Another reference but I have not heard of the conversion you collegue speaks of.
