Our hospital has a list of "Interdepedant Nursing Actions" (INA's). Is that what you mean??? It's a modest list of things that our hospital and the physician agreed upon for nurses to do. . . . I think so that nurses don't have to wake MD's up at 3:00 in A. M. for. . . .
But it is a nice list of things we can do without getting an MD's order right away.
Tylenol for temp with person already on antibiotics therapy.
Oxygen for SOB (then call MD!)
Lots of enema orders!

Foley cath for urine retention greater than 400 cc (found on bladder scan).
Mylanta for indigestion
EKG for suspicious cardiac stuff
This is only a small list of INA's available to us (just doing this off the top of my head, at present.)
In our happy little ICU/CCU, we can give lidocaine for sustained symptomatic V-tak, Atropine for symptomatic bradycardia and. . . of course. . . Defib for V-Fib. Then we call the MD.
I hope that this is helpful.
