Final answer:
The client's statement that they should shower with hot water to moisturize their skin indicates a need for further teaching about preventing dry skin.
Step-by-step explanation:
The statement by the client that indicates a need for further teaching about preventing dry skin is option A) 'I should shower with hot water to moisturize my skin.' This statement is incorrect because hot water can actually strip the skin of its natural oils and moisture, leading to further dryness. It is important to shower with lukewarm water and avoid using very hot water to prevent dry skin.
