It's interesting that you'd use an example like that. Let's really look at that, shall we? Now, while I have no doubt that there are many RN's out there that have the autonomy to start the above med's without consulting with a doc, for the vast majority, that will not be the case. (just like there will be many paramedics who are able to do various procedures/administer various meds that the vast majority will not) No, what they'll be doing is getting an order from a doc for an amount of the med to be given over a certain time. Do a bit of math, set the IV pump, and you're done. Not that complicated. Even starting it autonomously, still not that complicated, although more knowledge is definetly required. Why did I bring this up? Because I really don't like hypocrisy, and saying the above is no different that someone saying how much better paramedics are because we can intubate and most RN's can't.
If you're going to point out why it might not be beneficial to have the average paramedic working in an ICU setting (just like the average RN for that matter) you should probably stick to valid arguements; there are plenty out there, which I'm sure you know.
