Which nursing intervention helps prevent urinary tract infections?

The nursing intervention that helps prevent urinary tract infections is to encourage individuals to empty their bladder before and after intercourse. This practice is effective because it helps to flush out any bacteria that may have entered the urethra during sexual activity, thereby reducing the likelihood of infection. Urinary tract infections are often caused by bacteria ascending from the urethra into the bladder, and this intervention can significantly decrease the chances of such occurrences.

In terms of the other options, limiting fluid intake can actually increase the risk of urinary tract infections by concentrating the urine, which might allow bacteria to thrive. Encouraging late-night hydration is not advisable as it may lead to increased trips to the bathroom at night and doesn't specifically address prevention around activities that can lead to infections. Restricting bathroom access is counterproductive, as proper access and the urge to urinate regularly are essential components of urinary tract health. Therefore, the recommended intervention not only focuses on proper hygiene practices but also promotes a proactive approach to urinary health.
