In a hand winged blood collection, where is the tube placed after entering the vein?

• A. In the gauze pad at the site
• B. In the sharps container
• C. In the vacutainer hub
• D. On the patient’s arm

Answer: (C)

After the butterfly needle is in the vein, you insert the evacuated blood collection tube into the hub of the vacutainer. The vacuum inside the tube pulls blood into the tube automatically as the stopper is pierced and the needle remains in place. The gauze pad at the site is used to blot and apply pressure after removal, the sharps container is for disposing of the needle, and you don’t place a tube on the arm for collection. The tube must be seated in the hub to start filling.
