A nurse is caring for a client following insertion of a subclavian nontunneled percutaneous central venous catheter (CVC). The provider writes a prescription to initiate an IV infusion of Ringer's lactate at 150 mL per hr. Prior to starting the infusion, which of the following actions should the nurse take?

A. Apply oxygen at 3 L/min per nasal cannula: While oxygenation is important, there is no

indication in the scenario that the client requires oxygen supplementation at this time. Checking oxygen saturation would be more relevant if there were respiratory concerns.

B. Review the chest x-ray report: This is the most appropriate action before initiating the IV

infusion to ensure proper placement of the central venous catheter and absence of complications such as pneumothorax or malposition.

C. Flush the catheter with sterile water: Flushing the catheter with sterile water is not necessary before starting the infusion, especially without confirming proper catheter placement through chest x-ray.

D. Obtain a peripheral blood glucose level: While monitoring blood glucose levels may be

important in certain clinical situations, it is not directly relevant to initiating an IV infusion of Ringer's lactate via a central venous catheter.
