This might be a dumb question, but for the Lasix, is the liquid supposed to also be in the pointier tip of the syringe which is above the 0 line? Or no liquid in there? I was just drawing some up and it seems like insulin where there are bubbles and it can fill or not that space ahead of the 0 line, which is substantial, imo.
Nevermind, I found out that amount, if any is in that hub area about the 0, to not worry about it.
