A 90-year-old resident of a long-term care facility has a history of dementia, diabetes, mellitus, peripheral vascular disease, and osteoarthritis. He is totally dependent in activities of daily living (ADLs). Over the course of the past 2 weeks, he is noted to have a decreased appetite and a sudden change in behavior. He is being discussed at the team meeting due to this change in behavior.
The RN reports that when the nurse aids attempts to get him out of bed, he actively resists and strikes out. He also screams when being showered, especially when his lower extremities are washed, and when being dressed. He has been moved to a private room in the facility due to his behavioral changes disturbing his roommate. The RN reports that he has a large ulcer on the medial aspect of his left foot as well as a small ulcer on the malleolus. His right heel is reddened and soft to touch. The patient’s daughter is present at the meeting and asks the RN whether she thinks her father is in pain. The RN responds that she attempted to administer the pain scale but that he was not able to respond.
