Final answer:
The statement is true; pressure ulcers can develop even with proper risk evaluation and preventive measures in place, particularly among immobile elderly patients, and can lead to serious complications if untreated.
Step-by-step explanation:
The statement that an unavoidable pressure ulcer means that the resident developed a pressure ulcer even though the facility had evaluated the resident's clinical condition and pressure ulcer risk factors is True. Pressure ulcers, also known as bedsores or decubitus ulcers, can indeed develop despite the best practices and preventive measures taken by healthcare providers. These ulcers occur due to prolonged, unrelieved pressure on bony areas, diminishing blood flow and leading to tissue necrosis. They are particularly common amongst the immobile elderly population. Facilities often implement regular repositioning schedules to minimize the risk; however, in some cases, bedsores can still form. Without proper treatment, such as the removal of necrotized tissue, these ulcers can become infected and potentially lethal.
