Correct!
The answer is: a butterfly catheter is used for intravenous (IV) administration of medications
A butterfly catheter is a small gauge needle, with a plastic set of "wings" just below the needle hub that make holding the needle easier and more stable. Below the wings is a short piece of flexible IV tubing to allow for greater flexibility and movement when attaching the syringe containing the medication or anesthetic agent. This set up also allows for easy saline flushing of the catheter and switching between different medication syringes if multiple drug administrations need to be made.
Butterfly catheters can also be used for aspirations (withdrawing of fluids or cells from a mass or body cavity). Additionally, a butterfly catheter could be used for flushing a wound area, but this is not commonly done, due to the small size of the needle and relative expense of a butterfly catheter compared to a simple flushing syringe.
