Which specimen collection technique is ideal for small or difficult veins?

• A. Straight needle puncture
• B. Vacutainer system
• C. Winged infusion set
• D. Fingerstick technique

Answer: (C)

The winged infusion set, often referred to as a butterfly needle, is particularly ideal for situations where veins are small or difficult to access. This technique features flexible wings that allow for better maneuverability and stability during the puncture, making it easier to position the needle in challenging veins, such as those found in pediatric patients or individuals with fragile veins. The design of the butterfly needle also allows for a more precise insertion angle, which can reduce the likelihood of causing damage to the vein walls or missing the vein completely. This technique minimizes discomfort for the patient while ensuring that blood can be collected effectively. The smaller gauge and comfortable grip make it especially useful in clinical settings where traditional straight needles or vacutainer systems might be less effective due to the conditions of the patient's veins.
