A nurse is caring for an older adult client who is at risk for skin breakdown. Which of the following interventions should the nurse use to help maintain the integrity of the client's skin?

A. Applying cornstarch can absorb moisture; however, it may not be the most effective method to maintain skin integrity and can cause friction when applying. B. A diet high in protein is essential for skin health and repair, as it supports tissue regeneration and helps prevent skin breakdown in vulnerable clients. C. Massaging bony prominences is not recommended, as it may cause further tissue damage or disrupt circulation. Instead, padding and reducing pressure on these areas is more beneficial. D. Repositioning the client every 3 hours may not be frequent enough for someone at high risk for skin breakdown; generally, repositioning should occur at least every 2 hours to alleviate pressure.
