The regular insulin should be drawn up first. It is b/c after you then stick the same syringe into the long-acting, you could accidentally mix insulins (potentially) so if you put rapid acting into long-acting bottle, less problems that if you put long acting into rapid acting bottle. Ex, suppose he needed an in between hit of reg insulin (clear) during the day, he could [i]potentially[i/] get a mix of both insulins ( and so get long-acting insulin which would peak at a diff time and drop his blood sugar) if they are drawn up by using NPH first. The amounts would likely be miniscule, but that is the reasoning behind it, at least that was what I was taught. I hope that made sense.
It makes no difference as to which insulin hits the subq tissue first. It will all work the way it is supposed to work once it gets there.
I highly doubt it is your fault his sugars are out of whack b/c of your technique! If diabetics eat sugary foods, this is what sends their sugars out of whack. This happens a lot in older folks. He is probably buying more convenience foods since he can't see to cook. If you want to help him, contact his doc and ask for a visiting nurse referral, they can do an eval, teaching, send an RD if needed, etc. Also, Maybe he would like Meals on Wheels, he can get 2 meals a day for very low cost, one hot and one for later or vice versa. Finally, contact the nearest Association for the Blind in your area, they have some devices that attach to insulin syringes to make drawing up injects easier, and also he may want to consider a talking glucometer. A visiting nurse can help coordinate all this.
Thanks for caring about your neighbors!! You are a special person :kiss
