Which patient scenario benefits from using a butterfly system?

• A. A patient with very small or fragile veins
• B. A patient with large veins
• C. A patient who needs rapid infusion
• D. A patient requiring no special equipment

Answer: (A)

Butterfly systems are designed for difficult venous access, especially when veins are very small or fragile. The winged, small-gauge needle with flexible tubing lets you access tiny or delicate veins with greater control and less tissue trauma, making insertion easier and reducing the risk of vein damage or infiltration. This is why a patient with very small or fragile veins benefits from a butterfly system. In contrast, large veins typically tolerate standard IV catheters well, rapid infusions require a larger-bore catheter for higher flow, and if no special equipment is needed, a butterfly isn’t necessary.
