The sterile saline for catheter irrigation should be poured into a sterile, not clean, basin. This reduces introduction of bacteria into the urinary tract. The nurse stops the student nurse if this is done and instructs the student nurse to obtain new saline and a sterile container. Emptying the collection bag prior to the procedure ensures accurate charting of the urine output. Performing hand hygiene and donning clean gloves is an appropriate intervention. The student nurse is correct to use hospital-approved antiseptic swab to clean the access port.
