could u give me some feedback? i am a rn. they say u learn something new everyday but too my surprise it was something i never expected. recently my supervisor instructed me regarding contamination of primary tubing. during administration of primary fluids my patient very combative and confused at the time pulled out her iv and during this time i set the tubing on the pole and consequently left the cap off the hub,(tip) of the tubing. well to my surprise was told that because of this the entire tubing was now contaminated based on bacteria migration up the tubing. now after 9years i felt like i was a new grad. please give me ur ideas of this it would be a huge benefit to my already crush compenency.
