Final answer:
Reassessment of skin in a long-term care setting is crucial to detect pressure ulcers, which are a risk for immobile patients and can lead to serious health issues if not addressed promptly.
Step-by-step explanation:
In a long-term care setting, reassessment of the skin is important to detect pressure ulcers or skin breakdown (Choice C). Skin and its underlying tissue might suffer due to excessive pressure, leading to conditions such as bedsores, also known as decubitus ulcers. These sores result from prolonged, unrelieved pressure on bony parts of the body, which diminishes blood flow and leads to tissue necrosis. Individuals who are immobile, particularly the elderly with debilitating conditions, are at higher risk for bedsores. Long-term care facilities often implement patient-turning regimens to mitigate this risk. Prompt detection and treatment are imperative as bedsores can lead to serious infections or even be fatal if neglected.
