Final answer:
Pressure injuries, also known as bedsores or decubitis ulcers, are caused by constant, long-term, unrelieved pressure on certain bony areas of the body. Factors that can contribute to pressure injury development include immobility, advanced age, debilitating conditions, and prolonged pressure on the skin. Injuries such as burns, wounds, scars, and calluses can also increase the risk of pressure injuries.
Step-by-step explanation:
Pressure injuries, also known as bedsores or decubitis ulcers, are caused by constant, long-term, unrelieved pressure on certain bony areas of the body. This reduces blood flow to the area, leading to tissue death. Factors that can contribute to pressure injury development include immobility, advanced age, debilitating conditions, and prolonged pressure on the skin. Injuries such as burns, wounds, scars, and calluses can also affect the skin and increase the risk of pressure injuries. Other contributing factors include poor nutrition, reduced blood circulation, and comorbidities.
