I'm a new grad and have a question about flushing peripheral IVs. I was taught in nursing school
not to flush an iv if there is pressure when attempting to flush it because there could be a blood clot formed at the end of the cannula. So on one of my patients I couldn't get a hep lock to flush, so I called the iv nurse to look at it. She said she was able to get it to flush just fine. I know the cannulas can get bent and that makes them harder to flush, but what I am concerned about is the coagulation. How likely is it that by pushing against pressure I can push a clot into the blood stream and harm the pt? And what about when blood backs up into a hep lock and kinda stays there even when it's flushed? Could that cause coagulation or infection? These are questions I've wanted to ask our iv nurses, but a little too scared to look stupid...thanks for your help.
