Is it true that there are only two stages of pressure sore development?

The statement that there are only two stages of pressure sore development is not accurate. In fact, the development of pressure sores, also known as pressure ulcers, is classified into four stages based on the severity and depth of tissue damage.

Stage I indicates non-blanchable erythema of intact skin, where the skin remains intact but may exhibit color changes. Stage II involves partial thickness skin loss, presenting as an open sore or blister. Stage III indicates full thickness skin loss that may extend down to the fascia. Stage IV represents full thickness tissue loss with exposure of bone, tendon, or muscle.

Additionally, there are also categories for pressure ulcers that are unstageable or healed. Therefore, the notion of only having two stages oversimplifies the complex nature of how pressure sores develop, highlighting why the answer is indeed false. Understanding these stages is vital for prevention and effective treatment, particularly for individuals at high risk of developing pressure ulcers.
