Final answer:
When assisting a client with perineal care, you should begin wiping in the cleanest area and work towards the dirtiest area.
Step-by-step explanation:
The correct answer is D. When assisting a client with perineal care, you should begin wiping in the cleanest area and work towards the dirtiest area. This helps to prevent the spread of bacteria from the dirtier areas to the cleaner areas. Starting from the cleanest area also ensures that you are not reintroducing bacteria to areas that you have already cleaned.
