I'm new to the Emergency Department. We usually start an IV bolus wide open off the pump on most of our patients. I see a lot of nurses giving IV push medications and not pinching off the tubing above the distal port when pushing medications. I've asked several of the nurses about this practice, and they've told me as long as they have an IV that's working well they won't pinch the tubing. They slowly push the drug while the NS is infusing. This gives a slow, even push. My concern with this method is that the drug could back prime up the line.
On the other hand, if you do pinch off the tubing (like all the textbooks say to do) and are giving an undiluted drug, how do you control the rate of administration? Do you push a little, release the tubing, push a little? Are both methods considered acceptable?
I know there are other threads about diluting all IV push medication with NS so that the push can be better controlled. I hope this isn't a redundant thread.

If the site is patent and the maintenance fluid is flowing well, there's no reason to think that an IVP would backflow. The maintenance fluid would prevent that from happening.
I do not pinch off, because I like the dilution factor of the maintenance fluid when I give an IVP.
Besides, even if it did backflow, once you're done pushing it and the maintenance fluid is running again, it will all go right into the pt anyway.

Back priming's not a concern for two reasons: the pressure from the fluids will push it in, especially if the bag's high and wide open; or when you finish the fluids will flush it. I've given colored pushes through free flowing fluids, and it's not gone up any significantly up. Our tubing does have a one way valve below the main bag of fluids.
Definitely need to flush between, we actually just had an inservice by some tubing people, and she said up to 0.1mL can stay in a luerlock port on tubing.
