An older adult client has a normal saline IV infusion at 45 mL/hour. The client reports pain at the IV insertion site. No redness or edema observed around the IV site. Which action should the nurse take?

Determine what IV medications have recently been administered.

Consult with the healthcare provider (HCP) about the best location to start a new IV.

Convert the IV to a saline lock and continue to monitor the site.

Explain that without redness or edema, there is no need to restart the IV.
