What is generally the first step in the venipuncture process?

Applying the tourniquet is typically the first step in the venipuncture process because it helps to engorge the veins with blood, making them more visible and easier to palpate. This step is crucial in ensuring that the phlebotomist can select an appropriate vein for the blood draw. By temporarily restricting the blood flow, the tourniquet allows for better identification of the vein that is most suitable for venipuncture.

After applying the tourniquet, the next steps usually involve selecting the vein, cleaning the site to maintain aseptic conditions, and then proceeding to insert the needle. Each of these subsequent actions relies on the preparation done during the initial application of the tourniquet, as it directly impacts the ease of obtaining a good blood sample.
