Diluting IV narcotics = narcotics tampering?

This was posted per our staff developer today on our hospitals website. I am going to ask her to leave a copy of it in my mailbox and also to see examples of when diluting a med was considered a crime. She advised that when diluting we are tampering with the med. As soon as I saw it, i was like, "you've got to be kidding me woman. are you mad? how on earth is this realistic? also, are we going to start throwing out all of our drug reference books if we are going to rewrite them? it clearly states in our drug guides that MS and dilaudid both have to be diluted if given in a direct route!" ARGH...i talked with another nurse on our floor and she told me, "well P&P change so often so it will probably be back to the old ways again." If only we would look at pt safety for ALL things!!!
