A nurse is caring for a female client in an outpatient clinic. Which of the following actions by the client increases the risk of bacterial vaginosis?

Bacterial vaginosis results from an imbalance in the normal vaginal microflora, specifically a decrease in Lactobacilli. Knowledge of vaginal pH and protective mechanisms is required. The analysis focuses on behaviors that disrupt the natural acidic environment and allow for overgrowth. Choice A rationale Oral hormonal contraceptives do not typically increase the risk of bacterial vaginosis. In fact, some studies suggest that hormonal stability might help maintain a consistent vaginal environment, unlike behaviors that physically flush out the protective bacterial flora. Choice B rationale Condom use generally decreases the risk of many vaginal infections by preventing the introduction of semen, which is alkaline, into the vagina. This helps maintain the natural acidic pH level required for healthy Lactobacilli to thrive. Choice C rationale Voiding after intercourse is a common recommendation to prevent urinary tract infections by flushing bacteria out of the urethra. It does not negatively impact the vaginal flora or increase the specific risk for developing bacterial vaginosis. Choice D rationale Douching disrupts the natural vaginal flora by washing away protective Lactobacilli and altering the pH. This allows pathogenic anaerobic bacteria to overgrow, significantly increasing the risk of bacterial vaginosis and other pelvic inflammatory conditions through flora imbalance.
