A 6-year-old girl has been diagnosed with a urinary tract infection secondary to vesicoureteral reflux. Which statement by her mother indicates a need for further teaching?

Wiping from front to back is wiping from an area of lesser contamination (urethra) to an area of greater contamination (rectum). Generous fluid intake reduces the concentration of urine. Cotton is a natural, absorbent fabric. Nylon often predisposes the client to urinary tract infections. Dark, warm, moist areas are excellent media for bacterial growth. With vesicoureteral reflux, urine refluxes into the ureter(s) during voiding and then returns to the bladder (residual), which becomes a source for future infection.
