You can tell you are in a vein when using a butterfly needle by observing a few key signs. First, you should feel a sudden give or a slight drop in resistance as the needle enters the vein. Additionally, you may notice blood flash back into the chamber of the needle or the tubing, indicating successful venous access. Finally, if the blood flows easily when you gently pull back on the plunger, it confirms that you are properly positioned within the vein.

Using the incorrect needle size for the vein. (A small needle on a big vein and a large needle on a small vein)
What degree is the angle used between the skin and needle when using a butterfly collection system?
When using a butterfly collection system, the angle between the skin and the needle is typically around 15 to 30 degrees. This angle helps to ensure that the needle enters the vein smoothly while minimizing discomfort for the patient. Proper angling is crucial for successful venipuncture and reducing the risk of complications.
When drawing blood what happened when blood squirts in the tube and stop?
After the blood began to flow, the needle may have been inadvertently moved. When this happened, the needle either advanced forward or backward. If forward, the bevel may moved to rest against the vein wall, or went through the vein. If backward, the needle may have come out of the vein, but not out of the arm.

What is the best angle for needle insertion during venipuncture and why?
Because the goal of the procedure is to place a plastic catheter into the vein. If you insert the needle/catheter vertically you will go through the vein. If you angle on insertion once placement in the vein is confirmed you can slide the hollow catheter off of the needle into the vein. The veins used for most IV's normally lie just under the skin. For this reason a shallow angle of insertion is used.
