When using a butterfly needle set to obtain a blood sample, which action should the medical assistant take?

When using a butterfly needle set to obtain a blood sample, holding the needle by its wings is the correct action. The wings of the butterfly needle provide a stable grip for the medical assistant, allowing for better control and maneuverability during the blood draw. This grip reduces the risk of the needle moving or slipping during the procedure, which is crucial for ensuring that the blood is drawn correctly and safely.

Using the wings also helps to stabilize the needle in the vein, which is particularly important in smaller veins or for patients with difficult venous access. This technique contributes to a smoother procedure and can enhance patient comfort while minimizing trauma to the vein.

Other options, such as curving the needle tip, inserting it at a 90-degree angle, or using a large gauge needle, may not be appropriate for the procedural technique involving a butterfly needle. Butterfly needles are typically inserted at a shallower angle, and their design allows for easier access to veins without needing to curve the needle. The gauge size should also be selected based on the specific situation and the patient’s needs, rather than opting for a larger gauge without considering the context.
