A nurse is caring for a client who requires a re-insertion of a short peripheral venous catheter. In which of the following locations should the nurse place the catheter?

A. A vein proximal to the previous site: Placing the new catheter in a vein proximal to the old site helps maintain vein integrity and reduces the risk of infiltration, thrombosis or infection that might have occurred at the previous site from affecting the new site. Using a fresh, undamaged vein ensures better blood flow and minimizes complications like phlebitis. B. A vein that feels hard to the touch: A vein that feels hard may indicate previous inflammation, thrombosis, or sclerosis. Inserting a catheter into such a vein increases the risk of infiltration, pain, and poor catheter function. C. A vein on the client's wrist: Wrist veins are generally avoided due to limited subcutaneous tissue, reduced vein stability, and proximity to nerves and tendons, increasing the risk of injury and discomfort for the client. D. A vein in the client's dominant arm: While not absolutely contraindicated, the dominant arm should be avoided when possible to prevent interference with daily activities and reduce the risk of dislodging the catheter due to frequent movement.
