Section 1: Fundamentals of Brain Injury
1. What is the most common cause of traumatic brain injury (TBI)?
a) Falls
b) Motor vehicle accidents
c) Violence
d) Sports injuries
Answer: a) Falls
Explanation: Falls are the leading cause of TBI across all age groups, particularly
in the very young and the elderly.
2. A brain injury caused by a foreign object penetrating the skull is known as:
a) A closed head injury
b) An acquired brain injury
c) An open head injury
d) A hypoxic injury
Answer: c) An open head injury
Explanation: An open head injury involves a break in the skull, such as from a
bullet or shrapnel.
3. Which type of brain injury results from a lack of oxygen to the brain, such
as from a near-drowning or cardiac arrest?
a) Traumatic Brain Injury
b) Anoxic/Hypoxic Injury
c) Concussion
d) Contusion
Answer: b) Anoxic/Hypoxic Injury
Explanation: Anoxic injuries involve a complete lack of oxygen, while hypoxic
injuries involve a severe reduction.

,4. The Glasgow Coma Scale (GCS) is used to measure:
a) Long-term cognitive recovery
b) Level of consciousness after injury
c) Severity of post-traumatic amnesia
d) Motor skills recovery
Answer: b) Level of consciousness after injury
Explanation: The GCS assesses eye, verbal, and motor responses to determine the
initial severity of a brain injury.
5. Post-traumatic amnesia (PTA) refers to:
a) The permanent loss of memories from before the injury.
b) A state of confusion and inability to form new memories after the injury.
c) The inability to remember the actual event of the injury.
d) A type of seizure disorder.
Answer: b) A state of confusion and inability to form new memories after the
injury.
Explanation: PTA is a period of disorientation and impaired memory consolidation
following emergence from a coma.
6. The "silent epidemic" refers to:
a) Stroke
b) Alzheimer's Disease
c) Traumatic Brain Injury
d) Spinal Cord Injury
Answer: c) Traumatic Brain Injury
Explanation: TBI is often called the "silent epidemic" because its long-term
cognitive and behavioral effects are not always visible.
7. An acquired brain injury (ABI) is BEST defined as:
a) Any injury to the brain that is not hereditary, congenital, or degenerative.
b) Any injury to the brain caused by an external force.
c) An injury occurring only after birth due to trauma.
d) A specific type of stroke.
Answer: a) Any injury to the brain that is not hereditary, congenital, or
degenerative.

, Explanation: ABI is an umbrella term that includes traumatic causes (TBI) and
non-traumatic causes like stroke, infection, and anoxia.
8. A concussion is generally classified as what grade of TBI?
a) Severe
b) Moderate
c) Mild
d) Penetrating
Answer: c) Mild
Explanation: A concussion is a mild traumatic brain injury (mTBI) that
temporarily disrupts brain function.
9. Coup-contrecoup injuries involve damage:
a) Only at the site of impact.
b) Only on the side opposite the impact.
c) At both the site of impact and the opposite side.
d) Diffusely throughout the brain.
Answer: c) At both the site of impact and the opposite side.
Explanation: The brain hits the skull at the point of impact (coup) and then
rebounds to hit the opposite side (contrecoup).
10. Which of the following is a non-traumatic cause of an acquired brain
injury?
a) Gunshot wound
b) Assault
c) Toxic exposure
d) Sports collision
Answer: c) Toxic exposure
Explanation: Toxic exposure (e.g., carbon monoxide poisoning) is an internal event
that damages the brain, making it non-traumatic.

11. The frontal lobes are primarily responsible for:
a) Vision
