Which of the following describes a compound fracture?

A compound fracture is characterized by the broken bone piercing through the skin, which exposes the fracture to the outside environment. This type of fracture is considered more serious than a simple fracture, where the skin remains intact. The exposure of the bone to elements increases the risk of infection and complicates healing. Understanding the implications of a compound fracture is essential in nursing practice, as it necessitates immediate medical attention to prevent complications. Recognition of surroundings, wound care, and stabilization of the fracture are key nursing responsibilities in such cases.

The other options describe different conditions that do not align with the definition of a compound fracture. This distinction is crucial for a nursing assistant to ensure accurate assessment and reporting in clinical settings.
