Your post made me remember something from our clinical -- we were learning the different types of Insulin - NPH, Regular, Lantus, etc. Whenever we drew them up, the instructor asked what type it was - long acting, rapid, etc. For the life of me I couldn't get NPH down, so I made up a mneumonic - NPH is longacting so No Particular Hurry is what got me through those clinicals! Also, I made up Lantus is Long, Regular is Rapid, Humalog is Hurry/ also fast.
Here's a really neat site that helped me a lot when we were learning Insulin injections, mixing, etc. Gives you a narrated video of demonstrations:
