A nurse is caring for a patient with an indwelling catheter. Which of the following nursing actions should be taken to help prevent catheter-associated urinary tract infections (CAUTI)?


• The most important aspect of prevention of catheter-associated urinary tract infections (CAUTI) is avoidance of unnecessary catheterization and removal of the catheter as soon as possible

• Emptying the drainage bag frequently allows more accurate measurement of urinary output, and helps avoid contact of the drainage spigot with the collecting bag

• There is a high risk of infection if urinary leakage occurs, so a too-small catheter should be replaced with one that is larger

• Indwelling catheters should not be changed routinely if the flow is adequate and there are no mechanical problems, but perineal and catheter care should be performed routinely

• Urine samples should only be taken from catheters that have been in situ for less than 7 days, and full asepsis should be observed

• While irrigation can be used to clear blockages, the use of antimicrobials can lead to infection with more resistant organisms
