Correct Answer is A

Explanation

Choice A rationale
Drinking 16 oz of cranberry juice each day is correct. Cranberry juice has been shown to help prevent UTIs by inhibiting the adhesion of bacteria to the urinary tract lining. This can reduce the risk of infection, especially in individuals prone to recurrent UTIs.
Choice B rationale

Using an over-the-counter douche product after intercourse is incorrect. Douching can disrupt the natural balance of bacteria in the vagina, increasing the risk of infection. It is generally not recommended as a preventive measure for UTIs.
Choice C rationale
Waiting to void until the bladder feels full is incorrect. Delaying urination can lead to the accumulation of bacteria in the bladder, increasing the risk of infection. It is important to urinate regularly and not hold urine for extended periods.
Choice D rationale
Wearing underwear made from nylon is incorrect. Nylon underwear can trap moisture and create a warm, humid environment that promotes bacterial growth. It is better to wear breathable, cotton underwear to reduce the risk of UTIs.
