<s>[INST] My husbands blood sugar tested at 575 at 11 pm. He changed his insulin pump site and I s trying to go to sleep now. Our plan is for me to wake him at 1 am and test his sugar again. He is a type 1 diabetic, 60 yrs old, and a 6-bypass survivor. What should I expect for acceptable improvement, and what signs of danger do I need to watch for? He has been very irritable and was a bit confused earlier, but was able to clear up his thinking. I am worried about the possibility of his having a stroke, plus, we don t have any strips for testing for ketones - he was never educated on those, and I m new to all of it. Thanks for any advice you can offer.
