When using a butterfly needle for venipuncture on dorsal hand veins, which of the following actions should the phlebotomist take?

Rationale

Hold the needle by the wings of the butterfly.

Using the wings of the butterfly needle allows for better control and stability during venipuncture, which is particularly important when accessing smaller veins, such as those in the dorsal hand. This grip minimizes movement and reduces the risk of puncturing through the vein.

A (Position the needle at a 45° angle to the skin.) YOUR ANSWER

While the angle of insertion is important, a butterfly needle is typically inserted at a lower angle, around 10 to 30 degrees, particularly for smaller veins to prevent damage. A 45° angle is too steep for most venipuncture procedures and could increase the risk of complications.

C (Instruct the patient to hold the collection tubes.) YOUR ANSWER

It is not advisable for patients to hold collection tubes during venipuncture, as this can cause movement and potentially lead to inaccurate draws or complications. The phlebotomist should maintain control of the collection process to ensure safety and accuracy.

D (Apply the tourniquet at the antecubital area.) YOUR ANSWER

Applying a tourniquet at the antecubital area is not appropriate when accessing dorsal hand veins. The tourniquet should be placed around the upper arm to engorge the veins in that area. For dorsal hand veins, the tourniquet may restrict blood flow unnecessarily or complicate the procedure.

Conclusion

In performing venipuncture using a butterfly needle on dorsal hand veins, holding the needle by the wings is essential for effective control. Other actions, such as the angle of insertion, patient involvement, and tourniquet placement, may lead to complications or are not suitable for this specific procedure. Proper technique ensures a safe and efficient blood draw.
