A nurse is caring for an older adult client who reports dry, itchy skin. Which of the following actions should the nurse take?

A. Add moisturizing oil to the client's bath water: While oils can provide some moisture, adding them to bath water may create a slippery surface, increasing the risk of falls in older adults. Direct application of moisturizer after bathing is more effective and safer for maintaining skin hydration. B. Place a humidifier in the client's room: A humidifier increases ambient humidity, which helps prevent skin from drying out in environments with low moisture. This intervention is safe, effective, and can provide continuous relief from dry, itchy skin in older adults. C. Apply powder to the client's skin: Powders can irritate already dry or sensitive skin and may promote caking or fungal growth if moisture is present. They do not provide hydration and are not recommended for managing dry, itchy skin. D. Encourage the client to bathe frequently: Frequent bathing, especially with hot water or harsh soaps, can exacerbate dryness and irritation. Limiting bathing to once daily or every other day, using lukewarm water and gentle cleansers, helps preserve natural skin oils.
