4units of novo rapid b4each meal
Did they tell you to eat specific meals?
In the long run, you'll probably learn about carb counting (e.g. have a look
if you want to peek) because fixed insulin doses for each meal don't work very well.
In this case, your high BG simply means that you don't take enough insulin for the meal in question*. Have you been told to adjust your doses yourself? If not, I'd suggest that you contact them sooner rather than later because the doses are clearly not working atm.
* Basically, you need to have both enough insulin to meet your cells' energy requirement and to move all the excess glucose out of the bloodstream. Lacking enough insulin for the former can be very dangerous and leads to DKA - but your negative ketone test rules this out.
It's also possible to have a "correction dose" to correct for high BG (e.g. if you misjudged the size of a portion), but you should probably discuss this with your DSN first. I'd estimate 1u of insulin to lower your BG by 3.5mmol/l (=100/(16+4+4+4) by rule of 100), so a reasonable correction dose might be 4u.
The above is, in more detail and with pretty flowcharts, summed up in
this document.
I think its just a matter of time when your dose can be adjusted
To be honest, I'm not sure I agree with this. Dose adjustment isn't rocket science (it would just take a phone call), and I don't think it's acceptable to leave a newly diagnosed diabetic with a dose that is, at best, nominally educated guess for two weeks. I don't think that it's OK to send people home without knowing that the insulin doses are appropriate if you haven't told them what to do if they're not and leave them with 20+ BG for weeks.
