This is a very interesting post. I love all the different opinions regarding the situation. What I do love and respect about nursing is that everybody nurses different. We have the same policy at my facility. Our midlines are labeled " Do not draw labs". However, I'm fortunate that on night shift we have a NOW (nurse on the way) nurse or what some hospitals call a resource nurse who is PICC certified. Also, some of our house supervisors are PICC certified. So I would have called one of them and explained the situation. Then I would have asked if they could come up and draw the lab or assist me in drawing the lab. That was a situation that needed immediate attention. I'm a charge nurse as well and I'm not going to argue with you. We are going to take care of business. So you call the doctor and as the charge nurse I will take care of the lab. Also, at my facility we do not place PICC lines on dialysis patients. They are only get central lines. The nephrologists believe that PICC lines ruins the veins for future fistula placement.
