What is a winged infusion set commonly used for?

A winged infusion set, often referred to as a butterfly needle, is specifically designed for venipuncture, particularly in smaller or more delicate veins. Its winged design allows for better control and stability when accessing the vein, which is especially useful when drawing blood from areas such as the hand. This makes it ideal for procedures where precision is crucial, like obtaining blood samples in patients with smaller veins or when traditional venipuncture techniques may be challenging.

While the use of winged infusion sets in other applications may exist, such as administering medications or fluids, or in specific catheter insertions, they are primarily recognized and regarded for their effectiveness and ease of use in drawing blood, especially from the hand. Therefore, option C correctly identifies the primary and most common use of a winged infusion set in a clinical setting.
