Final answer:
In perineal care, a nursing assistant should clean from front to back to reduce the risk of urinary tract infections by preventing bacterial spread (option A).
Step-by-step explanation:
When assisting with perineal care, the nursing assistant will clean the area from front to back. This method is critical to prevent the spread of bacteria from the rectal region to the urethra, which can reduce the risk of urinary tract infections (UTIs). It is particularly important for females due to their shorter urethral length, but is also a good hygienic practice for males.
The procedure for perineal care should be gentle, using a clean cloth, warm water, and sometimes a mild, non-irritating soap. After washing, the area should be patted dry with a clean towel to prevent moisture, which can lead to skin irritation or breakdown.
Hence, the answer is option A.
