What type of therapy may be harmful to a resident with severe skin ulcers?

Radiation therapy may be harmful to a resident with severe skin ulcers because this type of therapy involves exposing tissues to high doses of radiation. This exposure can further damage already compromised skin and impair the healing process of ulcers. Additionally, radiation can cause skin irritation and increase the risk of infection in areas that are already vulnerable.

In contrast, physical therapy and occupational therapy are typically designed to support mobility and functional abilities without directly affecting the skin's integrity. Hydrotherapy, depending on its implementation, can be beneficial for wound care as it helps clean the ulcer and promotes healing through moisture. Therefore, understanding the implications of different treatment modalities is essential for ensuring patient safety and promoting effective healing strategies in individuals with severe skin issues.
