You are caring for your patient with a temporary hemodialysis catheter who has not required dialysis in 4 days. When you change the dressing you note the site appears red and edematous. What would you do NEXT? Document your assessment and monitor the site. Flush the catheters with 10 cc on normal saline. Notify the provider and assess necessity. Withdraw and re-instill heparin into the catheters.
