The nurse is reinforcing teaching with the caregiver of 5-year-old twins regarding urinary tract infections (UTIs). The caregiver is puzzled about why her daughter has had three urinary tract infections but her son has had none. She reports that their diets and fluid intake are similar. Which statement would be accurate for the nurse to tell this mother?

Choice A reason: Urination frequency varies individually, not by gender, and isn’t a primary UTI risk factor. The shorter female urethra explains higher UTI rates, making this inaccurate and incorrect compared to the anatomical reason for the daughter’s recurrent infections in the 5-year-old twins. Choice B reason: Assuming poor hygiene without evidence is speculative and less relevant than anatomical differences. The shorter urethra is the primary UTI risk in girls, making this blaming and incorrect compared to explaining the biological factor contributing to the daughter’s infections in the teaching. Choice C reason: Vitamin C may support urinary health but isn’t gender-specific or a primary UTI cause. The shorter female urethra directly increases contamination risk, making this irrelevant and incorrect compared to the anatomical explanation for the daughter’s recurrent UTIs in the caregiver’s twins. Choice D reason: Girls’ shorter, straighter urethras allow easier bacterial access to the bladder, explaining higher UTI rates compared to boys. This anatomical fact aligns with pediatric urology evidence, making it the accurate statement to clarify the daughter’s recurrent infections for the caregiver of the twins.
