Apparently you didn't read your assignment nor the site I linked above.

I read it but didn't understand

What part of this don't you understand?

"Recurrent Infections in Women
Health care providers may advise women who have recurrent UTIs to try one of the following treatment options:
Take low doses of the prescribed antibiotic daily for 6 months or longer. If taken at bedtime, the medication remains in the bladder longer and may be more effective. NIH-supported research has shown this therapy to be effective without causing serious side effects.
Take a single dose of an antibiotic after sexual intercourse.
Take a short course—2 or 3 days—of an antibiotic when symptoms appear.
To try to prevent an infection, health care providers may suggest women
drink plenty of water every day
urinate when the need arises and avoid resisting the urge to urinate
urinate after sexual intercourse
switch to a different method of birth control if recurring UTIs are a problem"

Copied from the linked website.

The patient with recurrent urinary tract infections should be instructed to C. Drink plenty of water. Drinking plenty of water helps to flush out bacteria from the urinary tract, preventing the growth and spread of infection.

To reach this answer, we need to understand the factors that contribute to urinary tract infections and how to prevent them. Recurrent urinary tract infections can occur due to a variety of reasons, such as the presence of bacteria in the urinary tract, inadequate fluid intake, and poor hygiene habits. By addressing these factors, we can effectively prevent and manage urinary tract infections.

Option A, "Avoid eating undercooked meat," is not directly related to urinary tract infections. While proper food hygiene is important to prevent other types of infections, such as food poisoning, it does not specifically address the prevention of urinary tract infections.

Option B, "Prepare for a kidney transplant," is not relevant to the management of recurrent urinary tract infections. Kidney transplant is a treatment option for end-stage kidney disease, which is a different condition than urinary tract infections.

Option D, "Expect treatment with kidney dialysis," is also not applicable to the management of recurrent urinary tract infections. Kidney dialysis is a treatment used for individuals with kidney failure, not for treating urinary tract infections.

Therefore, option C, "Drink plenty of water," is the most appropriate instruction for a patient with recurrent urinary tract infections. Drinking adequate amounts of water helps to dilute urine, flush out bacteria, and maintain overall urinary system health.
