A nurse is caring for a client who is receiving a continuous IV infusion of Ringer's lactate via a central venous catheter. Which of the following actions should the nurse take prior to initiating the infusion?

The correct answer is B: Review the chest x-ray report. Before initiating the infusion, the nurse should review the chest x-ray report to confirm the correct placement of the central venous catheter. This is crucial to ensure that the infusion does not lead to complications such as infiltration, extravasation, or damage to surrounding structures. Checking the client's oxygen saturation level (A) is important but not directly related to the initiation of the IV infusion. Flushing the catheter with sterile water (C) is not necessary as Ringer's lactate will be used for the infusion. Obtaining a peripheral blood glucose level (D) is important for diabetic clients but not a priority before initiating the infusion.
