Which statement defines a severe concussion (Grade 3) based on LOC and associated symptoms?

• A. Mild symptoms only
• B. Loss of consciousness with amnesia, vomiting, and tinnitus
• C. Drowsiness
• D. Headache with no LOC

Answer: (B)

The main concept is how concussion severity is classified by loss of consciousness and accompanying symptoms. Loss of consciousness marks a higher grade, and when it occurs with memory disruption (amnesia) and vomiting, it signals a more significant brain disturbance, typically described as a severe or Grade 3 concussion. The presence of tinnitus can occur with concussion but does not by itself define severity; the key combination is LOC plus amnesia and vomiting, which together indicate a serious injury. The other statements describe milder scenarios: no LOC with only mild symptoms suggests a less severe concussion; drowsiness or a headache with no LOC points to milder injury as well.
