Explanation:

To stabilize a vein for phlebotomy, the standard practice is to anchor the vein by placing one finger above the site and another below. This prevents the vein from rolling or moving during insertion. The other options do not follow established phlebotomy vein stabilization protocols.

Answer:

Place one finger above the site and another below.
