Forgive me for asking such a basic question, but I am a new nurse and cannot find an answer anywhere. Seriously I have checked all my textbooks and online for an answer.
What exactly does it mean to "blow a vein"? What exactly is going on with the vessel? How whould I know that I blew a vein? What are the complications of a blown vein? How can I prevent blowing a vein when performing veinapuncture?
