Which of the following is a symptom of a concussion felt by the person?

• A. Dazed, confusion, clumsy movements
• B. Ringing in ears
• C. Headache, dizziness, nausea
• D. Loss of consciousness

Answer: (C)

Symptoms that a person feels after a concussion are subjective experiences the individual reports. The most common self-reported combination is headache, dizziness, and nausea, reflecting brain strain and vestibular disruption after impact. Headache tends to be the most frequent, dizziness indicates balance system involvement, and nausea is often tied to autonomic and vestibular responses. Other options describe signs that are either less universal (like ringing in the ears) or observable changes (such as confusion or clumsy movements) that may be noticed by others rather than something the person necessarily “feels.” So, the trio of headache, dizziness, and nausea best represents the typical self-reported symptoms a person experiences after a concussion.
