A nurse is providing teaching to a client about measures to prevent urinary tract infections (UTIs). Which of the following client statements indicates a need for further teaching?

Urinary tract infections are frequently caused by ascending fecal flora, particularly Escherichia coli, entering the urethra. Preventative teaching focuses on minimizing bacterial translocation and promoting the mechanical flushing of the urinary tract to prevent microbial colonization of the bladder and urethral mucosa. A. This statement is incorrect and indicates a need for further teaching. Wiping from back to front moves fecal contaminants and intestinal bacteria toward the urethral opening, significantly increasing the risk of infection. Clients must be taught to wipe from front to back to keep the urethral meatus as clean as possible. B. This statement is correct and shows understanding. Maintaining a high fluid intake (approximately 2 to 3 liters daily) ensures frequent voiding. This physical action of urination mechanically flushes bacteria out of the urethra before they can migrate upward to the bladder, effectively reducing the overall bacterial load. C. This statement is correct. Cranberry juice contains proanthocyanidins, which may help prevent E. coli from adhering to the epithelial cells lining the urinary tract. While it is not a cure for an active infection, it is a widely recognized dietary measure used for the prevention of recurrent urinary tract infections. D. This statement is correct. Regular and complete bladder emptying prevents urinary stasis. Stagnant urine in the bladder serves as an ideal culture medium for bacterial growth. By voiding every 3 to 4 hours and ensuring the bladder is empty, the client minimizes the time bacteria have to multiply.
