A nurse is providing care for a client who has a central venous access device. Which of the following actions should the nurse take when providing site care?

A. Clean the insertion site with betadine: While povidone-iodine (Betadine) can be used, current guidelines recommend using chlorhexidine for central line site care because it is more effective in preventing catheter-related bloodstream infections. Using betadine is not the preferred standard of care. B. Flush the catheter with sterile water: Central venous catheters should be flushed with sterile saline, not sterile water, to maintain patency and avoid hemolysis or electrolyte imbalance. Flushing with water can damage blood cells and the catheter. C. Use a 5-mL syringe to flush the catheter: A minimum of a 10-mL syringe is recommended when flushing a central venous catheter because smaller syringes generate excessive pressure that can damage the catheter. Using a 5-mL syringe increases the risk of catheter rupture. D. Wear sterile gloves when providing site care: Sterile technique is required when performing central line site care to prevent infection. Wearing sterile gloves protects the client from pathogens and is a critical step in maintaining asepsis during dressing changes and catheter maintenance.
