After exposure to a blast, which symptoms should be screened for as potential indicators of a traumatic brain injury (TBI)?

• A. Dizziness
• B. Nausea
• C. Headaches
• D. Dizziness, nausea, and headaches

Answer: (D)

After blast exposure, you should screen for dizziness, nausea, and headaches because these are common signs of a traumatic brain injury. Dizziness points to vestibular disruption and balance problems that can occur with brain injury. Nausea can accompany brain injury-related autonomic or vestibular issues and may signal that the body is reacting to brain trauma. Headaches are among the most frequent and can appear immediately or be delayed, indicating ongoing brain irritation or injury. Checking all three ensures you don’t miss a TBI diagnosis if only one symptom is present or if symptoms develop over time.

Focusing on only one of these symptoms could overlook another important indicator, since blast-related TBI can affect multiple brain systems and symptoms may vary in onset.
