Which of the following are symptoms of a broken bone?

The correct answer is indicative of the common symptoms associated with a broken bone. Swelling often occurs at the site of the fracture due to inflammation and tissue response to injury, resulting in increased blood flow to the area. Deformity can be a clear sign of a fracture, as the bone may be misaligned or cause an unnatural appearance in the limb. Inability to use the limb is a direct consequence of the pain and structural compromise from the fracture, which can prevent normal movement or bear weight.

Other choices include symptoms that may relate to different medical issues but do not specifically indicate a broken bone. For example, fever and nausea are generally associated with infections or systemic illnesses, while bruising and redness can point to soft tissue injuries or contusions rather than fractures. Dry skin and fatigue might suggest dehydration or other non-trauma related conditions. Understanding the specific signs associated with bone injuries is crucial for identifying and managing fractures effectively.
