Choice A rationale Minimizing the use of douching, perfumed sprays, or powders in the genital area is an important preventative measure against urinary tract infections. These products can disrupt the normal acidic pH and balance of the vaginal and perineal flora, leading to irritation or the proliferation of pathogenic bacteria like E. coli, which can then ascend the urethra causing infection. Choice B rationale While increasing fluid intake is generally recommended for a urinary tract infection to help flush bacteria from the urinary system, tomato juice is typically alkaline. An alkaline environment can promote bacterial growth. Cranberry juice, which makes the urine more acidic and inhibits bacterial adhesion to the bladder wall, would be a more beneficial instruction than tomato juice. Choice C rationale The instruction to wipe back to front after voiding is incorrect. The proper technique is to wipe front to back (urethra to anus). This prevents the transfer of E. coli bacteria, which are naturally found in the gastrointestinal tract, from the anal area into the relatively clean urethra, thus significantly reducing the risk of developing a urinary tract infection. Choice D rationale Antibiotics should be taken for the entire prescribed duration, even if symptoms such as dysuria (painful urination) resolve quickly. Stopping antibiotics prematurely can lead to a recurrence of the infection and contributes to the development of antibiotic-resistant strains of bacteria, which are much harder to treat effectively in the future. —.
