The nurse should obtain a baseline neurologic assessment before the procedure because there is a possibility that a thrombus can become dislodged, causing an embolus to travel to the brain, leading to neurologic impairment. The nurse should encourage large amounts of fluids, unless contraindicated, because of the radiopaque dye used. The nurse should apply a pressure device to the insertion site to reduce edema, bleeding, and hematoma formation and not to prevent scarring. The insertion site should be checked for bleeding every 15 to 30 minutes for several hours, and not at the end of every hour.
