What should the nurse include when teaching a client about compartment syndrome?

The correct choice highlights that compartment syndrome is indeed caused by bleeding and swelling in a space that cannot expand. This condition occurs when increased pressure within a muscle compartment impairs blood flow, leading to potential damage to muscles and nerves. Understanding this mechanism is crucial for both prevention and early recognition of the condition.

When the body experiences trauma, such as a fracture, there can be swelling within a closed space surrounded by fascia. Since fascia does not stretch, the pressure builds up, leading to decreased circulation. This can result in tissue ischemia, which may cause permanent damage if not addressed quickly.

The other options do not accurately capture the essence of compartment syndrome. While fractures can contribute to the condition, compartment syndrome is not exclusive to fractures, as it can occur with any situation that causes swelling or bleeding in a confined space. Additionally, it primarily impacts the musculoskeletal and nervous systems rather than the circulatory system alone, and it does not resolve with increased physical activity; in fact, activity may exacerbate the condition. Understanding these key aspects will empower healthcare providers to better assess and manage the risks associated with compartment syndrome.
