A nurse is reinforcing teaching with a female client who has a history of urinary tract infections. Which of the following instructions should the nurse include?

Urinating before and after sexual intercourse flushes bacteria from the urethra, a primary UTI prevention strategy, especially in women due to their shorter urethra. Milk consumption may alkalinize urine, but this doesn't prevent infection cranberry juice is more evidence-based, reducing bacterial adhesion. Vaginal douching disrupts normal flora, increasing UTI risk by promoting pathogen growth, contrary to hygiene goals. Emptying the bladder every 6 hours helps, but more frequent voiding (e.g., every 2-3 hours) is ideal; post-coital urination targets the key risk moment. This instruction empowers the client to reduce recurrence, aligns with urologic recommendations, and addresses a common trigger, making it the most effective teaching point.
