A pediatric nurse is assisting with the care of a child diagnosed with a fractured femur. What type of fracture would be the most likely cause infection?

A. A greenstick fracture is a partial fracture common in children and does not break the skin, so it carries a low risk of infection. B. Stress fractures are tiny cracks in the bone from repetitive force and are closed fractures, not typically associated with infection risk. C. A compound fracture (also called an open fracture) involves a break in the skin, exposing the bone and surrounding tissue to the external environment, which significantly increases the risk of infection. D. A spiral fracture is caused by a twisting force and can be suspicious for abuse in children, but unless the skin is broken, it does not inherently pose a high risk for infection.
