A nurse is caring for a client who has an indwelling catheter with a urinary drainage system. Which of the following actions should the nurse take?

A. Instructing the client to hold the drainage bag at waist height when ambulating is incorrect. The drainage bag should always be kept below the level of the bladder to prevent urine backflow, which can lead to infections (catheter-associated urinary tract infections - CAUTIs). B. Coiling the tubing on the bed above the collection bag is incorrect. Tubing should be secured below bladder level without kinks or loops to allow for continuous urine drainage and prevent urinary stasis and infection. C. Collecting a sterile specimen from the urinary drainage bag is incorrect. Urine in the drainage bag is not sterile and may contain bacteria, leading to inaccurate results. A specimen should be collected from the designated port on the catheter tubing using aseptic technique. D. Securing the tubing with adhesive tape to the lower abdomen is correct. For male clients, securing the catheter to the lower abdomen prevents urethral trauma and tension. For female clients, the catheter is typically secured to the inner thigh to minimize movement and irritation.
