Ok, so I know for the most part everyone agrees that you should pause any IV fluids or drips before drawing blood from a line. But do you typically only pause them if they are going into the same line, (i.e same line you're drawing from, just a different port), or do you also pause them if the are running into a totally different line?
What if you are drawing the blood from an art line? I am a new nurse, and my preceptor has had me redraw a lab because she noticed that I didnt have my drips paused. It just seems to me that if all these drips are infusing into a vein, by the time the blood circulates through the heart, lungs, and into the artery that I am drawing blood from that it would be a pretty accurate picture of the make-up of the blood anyways.
I feel the same about drawing blood from, say, the left arm when meds are infusing into the right arm.
I guess its good to be in the habit of pausing meds but I just don't feel its necessary all the time!

Our policy is to stop all drips afaik. An ABG off the a. line, you don't need to stop. I'm not so sure about labs off the a. line itself though. Specific for heparin, we are supposed to draw off an opposite limb after having the drip off for x amt of time (Idr honestly) unless their veins are just awful.
Now I've had accidentally sent in a lab that I didn't stop all the drips before. One of the drips ran in D5W. My blood glucose was sky high lol... Even tho logically if I draw at a vein lower than where it's infusing there shouldn't be a difference in labs, I stop stuff just in case anyways...
