For a pregnant woman, which of the following is a preventive measure against UTIs?

Wiping from front to back is an important preventive measure against urinary tract infections (UTIs) for pregnant women. This practice helps to minimize the risk of bacteria from the rectal area, where harmful bacteria can reside, being introduced into the urinary tract. During pregnancy, women may be more susceptible to UTIs due to anatomical and hormonal changes that can affect the urinary system, making proper hygiene practices essential.

Many of the other options would actually increase the risk of developing a UTI. Delaying urination can lead to the bladder becoming overfull, which may provide an environment for bacteria to multiply. Avoiding fluid intake can lead to concentrated urine, which irritates and increases the likelihood of infection. Restricting shower time is not directly related to UTI prevention and does not promote proper hygiene practices. Therefore, maintaining good hygiene, such as wiping from front to back, is an effective strategy for preventing UTIs in pregnant women.
