I love this name for a girl, in fact, I gave the name to my daughter. I spell her name Rianne and pronounce it Ryan, NOT Ree-ann! I thought the i would be softer and more feminine than a y and I thought the anne was more feminine than an. Just my thought.
Intramuscular Injections: Any one cc syringe for IM (intramuscular) injections is good to use. For IM, you need a needle that is one to one and a half inches long and, typically, a 25 gauge needle is used.
There are U100 Syringes designed for use with U100 insulin and U40 Syringes designed for use with U40 insulin. They were at one time color-coded: U100 syringes having orange caps while U40's have red ones. Unfortunately some U40's now have orange caps, too -- check the barrel carefully for U40 or U100 to be sure!
