Well, I've been on both ends. I'm an RN who has to deal daily with pts. who c/o "I'm going to sue if they don't get my dinner right this time." "Why does Susie have sores on her butt?" (Well, it's probably because she refuses to turn/follow protocol for pressure relief even though it's all been explained to her. (I work on a long term care ventilator unit.) But I have also been the mother bringing her child in for a fever of 105 and I've refused the spinal tap. I understand the rationale for and the consequences of. It was just my choice. And I understand the rationale of using selective antibiotics based on cultures, but at that time it didn't feel right to do and I told them I chose for them to treat him the most appropriately based on other info (lab draws, VS, O2 sats, etc.) He ended up getting Rocephin shots. Everything turned out OK. Maybe we were just lucky, but sometimes you just have a strong gut feeling about whether or not to do something, then I agree with the others. All you can do is educate (including making sure they understand the information) and document response to and do the best you can do from there. (Of course, always keep a heads up about pt. competency!)
