Grade 2 concussion is described as...

• A. Grade 2: Moderate - symptoms last longer than 15 minutes, with loss of consciousness
• B. Grade 2: Mild - symptoms last less than 15 minutes
• C. Grade 2: Severe - loss of consciousness
• D. Grade 2: Moderate - symptoms last longer than 15 minutes, no loss of consciousness

Answer: (D)

Grade II concussions are considered moderate in severity and are defined by symptoms lasting longer than 15 minutes without loss of consciousness. This combination signals a more noticeable disruption of brain function than a brief, no-symptom-for-15-minutes event, but it does not include the loss of consciousness that marks the most severe end of the spectrum. So, the description of symptoms persisting beyond 15 minutes while consciousness remains intact best fits Grade II. The other descriptions mix the duration with the presence of loss of consciousness, which would place the injury into a more severe category, or describe a brief, mild presentation that would be considered Grade I.
