Hi guys, I need some advice. When drawing up the insulin I know to draw from the regular-fast acting first and then from the NPH or long acting last. I understand how to add them and such, my problem is that when I am drawing up the NPH I keep drawing up one unit over. I tried three times in check off and each time drew one unit over-so frustrating!!! ANd with mixed insulin we cannot adjust the dose after drawn, right? So any advice would be great. I started slowing down at 10 units, I needed 15, then when I started pulling the plunger i went right over to 16. I will check off for sub q tomorrow-hope I get this down!!
