A female teenager has experienced three uncomplicated urinary tract infections in the last 3 months. Knowing the anatomical location of the urethra, the nurse should educate this teenager about:

In females, the urethra is approximately 3–4 cm long and is located in close anatomical proximity to both the vaginal opening and the anus. This short length and anterior-to-posterior positioning means that bacteria from the rectal area, most commonly Escherichia coli, can easily migrate toward and into the urethral opening during perineal wiping. Teaching the patient to wipe from front to back after toileting is the single most important hygiene measure to prevent fecal flora from contaminating the urethra, thereby reducing recurrent urinary tract infections. This is the standard and evidence-based guidance given to females of all ages, but it is especially important to reinforce in adolescents who may not have received this education. The other options are incorrect because they address pathogens or techniques that are not the primary concern in recurrent UTIs in this population. Handwashing before tampon insertion is a good hygiene practice but targets group B Streptococcus in a context unrelated to the mechanism of UTI described here. Wearing gloves while wiping the perineum is impractical and not a standard recommendation. Teaching about Pseudomonas on the hands is a distractor, as Pseudomonas is not the typical causative organism in community-acquired UTIs in otherwise healthy teenage females; E. coli accounts for the vast majority of such infections.
