When using a butterfly needle set for a blood sample, what is the recommended action for the assistant?

Holding the needle by its wings is the recommended action when using a butterfly needle set for a blood sample. The wings provide better control and stability during the insertion process, allowing for a more precise placement in the vein. This grip helps prevent any unnecessary movement of the needle once it is in the vein, which is essential for minimizing discomfort for the patient and ensuring that the blood flow is steady without risking the needle dislodging.

Using the wings to hold the needle also makes it easier to manage the tubing attached to the needle without causing stress on the insertion site. This technique is particularly helpful in cases where veins may be difficult to access, as it maximizes both control and accuracy. Proper handling of the needle in this manner contributes to a successful and efficient blood draw.
