The school-age period is when many injury prevention habits are established for life. For the REx-PN exam, school-age injury prevention questions focus on: helmet fitting and selection, concussion recognition and return-to-sport protocols (NO same-day return is the most commonly tested point), and pedestrian safety. On the exam, writers often pair stable-sounding options with unstable dataโnotice the mismatch before you commit. If the stem names a license or role, reread that line; scope errors are classic trap answers even when the clinical topic is familiar. Run a 60-second scan: breathing work and oxygenation, perfusion and end organs, neuro baseline, likely infection sources, and devices that can fail quietly.
