What preventative measure can be taken to reduce the risk of urinary tract infections in patients with catheters?

The use of sterile technique during catheter insertion and maintaining proper drainage systems is critical in reducing the risk of urinary tract infections (UTIs) in patients with catheters. When catheters are inserted using sterile techniques, the chance of introducing bacteria into the urinary tract is minimized, which is essential for preventing infections. Additionally, ensuring that the drainage system is functioning correctly prevents backflow of urine, which can harbor bacteria and increase the risk of infection. Proper maintenance of the catheter site and the drainage bag is also fundamental in reducing contamination.

The other options, while they may seem relevant, do not effectively address the core issue of infection prevention as thoroughly as the recommended practices. For instance, using antiseptic wipes may help but is not as comprehensive as ensuring a sterile insertion technique. Limiting fluid intake is not advisable, as adequate hydration is essential for flushing the urinary tract. Changing catheters routinely without assessing the actual need can lead to unnecessary discomfort and increases the risk of introducing bacteria with each new catheterization. Therefore, using sterile technique and proper drainage is the most reliable method for preventing UTIs in patients with catheters.
