Which technique is recommended for minimizing a patient's risk for injury when inserting a venous access device?

Holding the skin taut directly below the site is recommended because this technique creates a more stable surface for the insertion of the venous access device. It helps stabilize the vein and minimizes the risk of movement during the procedure, which can lead to complications such as missed sticks or damage to surrounding tissues. Maintaining skin tension can also facilitate access to the vein by making it more prominent and easier to puncture.

In contrast, inserting the needle with the bevel down may not always be the best practice for venous access. Generally, the bevel should be facing up to allow for optimal entry into the vein and to reduce trauma to the vessel.

Using a vein on the palmar surface of the arm is not typically recommended either, as the veins found on the dorsal (or dorsal side) surfaces of the arms are generally larger and more suitable for venous access; those on the palmar surface are usually smaller and less accessible.

Therefore, the technique of holding the skin taut stands out as the best practice for reducing injury risk during this procedure.
