I'd never heard of it either, silky, and it made me wonder if she was just testing us to see how we'd respond. I'm pretty sure, though (can't really ASK someone in authority, they'll figure it out) we'll have to be tested before we do clinicals. Haven't decided what nursing yet (RN maybe, LPN likely), but the core classes are the same.

I'm hoping since it's routine, I can sub. Would be afraid to try the dilute...I'm a heavy smoker.
