Hello, I'm a new nurse and gave blood today for the first time but am questioning whether I administered it correctly. An experienced nurse who was my second witness and did the double check with me helped me set up the infusion. From what I remember in school, I thought we were taught to prime the whole line with saline first. I asked the other nurse about this and she said that after filling the drip chamber with saline that one should prime the whole line with blood instead. Was this correct? Also, I set the pump VTBI for the ordered amount. However, once you run the flush bag at the end and flush the line aren't you then by default pushing whatever blood is in the line into the pt thus giving them more blood than ordered? I thought perhaps I should deduct the volume amount of the line from my VTBI so that it would equal out once the flush is run. I asked a nurse who has given blood often and she said that was not necessary and that giving the extra blood that is in the line (which adds up to about 30ml) is okay. Is this right? Am I overthinking this? I checked with 3 nurses to verify I was administering it correctly, but I'm kinda freaking out that I made an error if what I did was wrong.
