So today I was reading a post about an RN who hung blood with D51/2NS instead of NSS. Many of the comments said that as a general rule always hand blood with NSS. This is not something I would instinctively know or remember in school. What are some other "general rules" from you more experienced nurses for us younger nurses? I had my own experience with a "general rule". The nursing school I went to never taught us to insert IV. They said hospitals are moving towards IV teams and if the facility that hires us wants RNs to insert IVs, they will teach us. They facility I work at does have RNs insert the IVs. I did my research, including watching youtube videos and reading a our facilities Mosbys skills for IV insertion. Nowhere do I remember it said IVs must point away from the heart. I inserted one IV in the forearm that point up towards the shoulder. Thankfully, everything was okay. However, I, even after doing research, did not know this simple rule (my charge nurse who found the error probably questioned my right to practice ), a rule many of you know. Is there anything else like this that comes to your mind to remind nurses?
