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.
If using insulin with 40 U/ml, you must measure and administer it with a U-40 syringe; using a U-100 or U-500 syringe would result in the wrong amount of insulin being given, with perhaps a fatal outcome. There may be several types of U-40 syringes available, manufactured to deliver low or high doses.
