What should EMS personnel do first when assessing a possible leg fracture?

• A. Assess vital signs
• B. Call a physician
• C. Apply heat to the injured area
• D. Compare to uninjured leg

Answer: (D)

When you suspect a leg fracture, the quickest way to spot abnormalities is to compare the injured leg with the uninjured one. This patient-specific baseline helps you see deformity, unusual angulation, swelling, or other signs that indicate a fracture, which isn’t always obvious just from looking at one leg alone. The comparison guides how you immobilize the limb and what neurovascular checks to focus on downstream. While monitoring vital signs is important, it doesn’t provide that immediate, injury-specific information as effectively. Applying heat would worsen swelling, and while contacting a physician may be part of ongoing care, it isn’t the first step in identifying the fracture.
