Final answer:
The most significant hazard of reduced mobility is the risk of pressure ulcers or bedsores. These are caused by constant pressure on bony areas of the body and can lead to tissue death or necrosis. If untreated, these can become infected and pose a severe health risk.
Step-by-step explanation:
The most significant hazard of restricted mobility is D) Risk of pressure ulcers (bedsores). When a person becomes immobile, either due to age or a condition like a hip fracture, they are at risk of developing sores and ulcers due to excessive and unrelieved pressure on bony areas of the body. This can restrict blood flow and lead to necrosis or tissue death.
Most commonly occurring in elderly and immobile patients, these bedsores can become life-threatening if they become infected and are not treated promptly. In many hospitals and long-term care facilities, regular repositioning of patients is practised to prevent bedsores. Inability to do so due to restricted mobility can thus lead to these pressure ulcers, amongst other risks like the formation of blood clots, respiratory failure or even infections.
