A 28-year-old married female patient with cystitis requires instruction about how to prevent future UTIs, and you have delegated this teaching to a newly-graduated RN. Which statement by the new nurse requires that you intervene?
1) "You should always drink 1 to 3 L of fluid every day."
2) "Empty your bladder regularly even if you do not feel the urge to urinate."
3) "Drinking cranberry juice daily will decrease the number of bacteria in your bladder."
4) "It's okay to soak in the tub with bubble bath because it will keep you clean."
