When using a Winged Infusion Set (Butterfly), what part of the device should be held for needle insertion?

1. Needle hub

2. Wings

3. Plastic adapter

4. Extension tubing

The correct answer is: Wings

Holding the wings of the Winged Infusion Set, commonly known as a butterfly needle, during insertion is important for several reasons. The wings provide a stable grip that allows for better control and precision when puncturing the skin, which is particularly beneficial in delicate venipunctures such as in pediatric or elderly patients. This approach minimizes the risk of movement that could result in a missed vein or going through the vein during the insertion process. Additionally, by using the wings as the gripping point, phlebotomists can maintain a clear view of the needle's angle and orientation, ensuring optimal insertion technique to facilitate successful blood collection. The wings are designed to make the procedure easier and more comfortable for both the patient and the phlebotomist. Properly utilizing the wings for support also helps prevent accidental needle stick injuries, contributing to overall safety during the procedure.
