A nurse is teaching a group of unlicensed assistive personnel about urinary tract infections (UTI) in clients who have vaginas. When describing why clients who have vaginas have higher rates of UTIs than clients who don't have vaginas, which of the following explanations should the nurse use?

A. Decreased strength of the detrusor muscle may contribute to urinary retention but is not the primary reason for increased UTI risk in this population. B. More alkalotic urine is not a gender-specific characteristic and does not explain higher UTI rates in clients with vaginas. C. Shorter urethra is correct; clients who have vaginas have a urethra approximately 1.5 to 2.5 inches long, allowing bacteria easier access to the bladder. D. Decreased bladder capacity is not a common factor in UTI susceptibility and is not significantly different between sexes.
