Which practice does NOT help decrease catheter-associated urinary tract infections?

Discontinuing enteral tube feeding if diarrhea occurs does not directly contribute to the reduction of catheter-associated urinary tract infections (CAUTIs). While diarrhea can lead to complications, the management of enteral feeding does not have a direct effect on the urinary catheterization itself or on infections that may arise from its use.

In contrast, using a straight catheter minimizes the risk of infection since it is used for intermittent catheterization rather than continuous use, which is associated with a greater risk of infection. Maintaining sterile technique during catheter insertion and care is crucial for preventing contamination and subsequent infection. Routine catheter care also plays a significant role in preventing CAUTIs by ensuring that catheters are properly managed and monitored, minimizing the risk of infection from other sources.

Thus, while all options involve aspects of patient care, only the discontinuation of tube feeding is unrelated to the practices that are established to prevent urinary tract infections associated with catheter use.
