I ordered lunch for my patient. I administered Novolin (11 units). Blood sugar was 295. Once food came Pt said he wasn't hungry. He just wanted to eat his peaches. So, he ate his peaches. Could the pt. bottom out from only eating peaches? (5 peach slices).
Before answering that, I would be curious to know if the 11 units was a sliding scale correction for the blood sugar only, if it was sliding scale for the carbohydrates in the meal only , or if it was a combination of both.
If it was only for the blood sugar of 295 and the pt insulin sensitivity ratio is indeed 18mg/dL glucose to 1 unit of insulin, then unlikely that they would bottom out, but could happen (assuming the correction target for blood glucose is around 100mg/dL). Plus the pt ate a few peaches.....
If, however, the insulin was combination of correction for glucose and carbohydrate content of the meal, then yes, much more likely to bottom out if pt did not eat the carbs that the insulin was "expecting to cover."
Lastly, if it was only a dose for the carbohydrate content of the meal, then the high blood sugar would have acted as a "buffer" in the sense that the patient already had his "carbs" on board.

It was a sliding scale of 9 units Novolin R and +2 units Novolin R (seperate from the sliding scale). I'm a student so i'm not really familiar with how insulin works. I'm trying to make sense of it all.....
