The nurse is assessing a child with a suspected fracture. Which finding is indicative of a complete fracture?

Choice A rationale When bone fragments remain partially joined, this describes an incomplete fracture, such as a greenstick fracture often seen in children, where the bone bends and cracks but does not break completely through. This is distinct from a complete fracture where there is full separation of the bone. Choice B rationale A complete fracture is scientifically defined as a break in a bone where the bone fragments are entirely separated from each other. This total discontinuity interrupts the structural integrity of the bone, distinguishing it from partial breaks where some bone continuity is maintained. Choice C rationale When the bone penetrates the skin, this describes an open (or compound) fracture. While an open fracture is also a complete fracture, the defining characteristic of a *complete* fracture itself is the full separation of the bone fragments, irrespective of whether the skin is breached. Choice D rationale When the bone bends but does not break, this is characteristic of a bent bone deformity or an incomplete fracture, specifically a greenstick fracture common in pediatric patients due to the higher flexibility of their bones. This is not a complete fracture, where the bone's continuity is fully disrupted.
