Anurse is caring for an older adult who was admitted to the hospital to be treated for dehydration. while the nurse is providing discharge teaching, the client says, "what should i do about my dry skin? it is so itchy." what is the best response by the nurse?

The best response is this: USE A MOISTURIZER ON THE SKIN DAILY TO HELP REDUCE ITCHING. 
Using a moisturizer on the skin is an effective mean of reliving dryness and in extension reducing itchiness. The moisturizer will keep the skin moist and thus reduce pruritus.
