I am a nursing student whose almost finished with the program. I've had less than twenty IV attempts so far with only 3 successful. Two of those were under the direct instruction of a nurse who was awesome at teaching and gave me the play by play. I've about made every mistake I can think of. However, I've learned from each one and have rarely repeated the same mistake except for one. I'm coming along well at identifying a locating veins even by feel. My angle is good and I know to anchor the vein. I tend to poke slowly, as I've been told, because I'm slightly hesitant. When I do pierce the vein, I can see the flash. This is where I mess up. My fear is infiltrating the vein so I tend to pull the needle back too soon before the catheter is threaded. The catheter will run into resistance because I don't think its in the vein probably because I've pulled the needle back to soon. Its happened on several occasions. Advice? Also, when I see the flash, should I begin level out my angle to be sure that I don't blow the vein?
