In the Quebec Task Force classification, a grade with no neck symptoms and no physical signs corresponds to which level?

• A. 1
• B. 2
• C. 0
• D. 3

Answer: (C)

This question hinges on the Quebec Task Force classification for whiplash injuries, which assigns a level from 0 to 4 based on symptoms and physical signs. The level where there are no neck symptoms and no physical signs represents an absence of both subjective and objective findings, so it corresponds to level zero. The other levels reflect increasing involvement: level one is neck pain without objective signs, level two adds musculoskeletal signs such as reduced range of motion or local tenderness, level three includes neurological signs, and level four involves a fracture or dislocation. Therefore, the level with no neck symptoms and no physical signs is level zero.
