Problem: Which infection prevention technique would be appropriate for the nurse to include when teaching a client being discharged with an indwelling catheter? Once a day, clean the tubing with a mild soap and water, starting at the drainage bag and moving toward the insertion site. After cleaning the catheter site, it is important to keep the foreskin pushed back for 30 minutes to ensure adequate drying. Clean the insertion site daily using a solution of 1 part vinegar to 2 parts water. Replace the drainage bag with a new bag once a week. Need Assignment Help?
