SECTION 1: BRAIN INJURY FUNDAMENTALS
Question 1
What is the definition of an Acute Brain Injury?
A) An injury to the brain that is hereditary or congenital
B) An injury to the brain that is not hereditary, congenital, degenerative, or induced by
birth trauma
C) An injury caused exclusively by external force
D) A degenerative neurological condition
Correct Answer: B
Explanation: An acute brain injury is defined as an injury to the brain that is not
hereditary, congenital, degenerative, or induced by birth trauma. This distinguishes it
from conditions like Alzheimer's disease or developmental disorders, and encompasses
both traumatic and non-traumatic causes .
Question 2
Which of the following best defines a Traumatic Brain Injury (TBI)?
,A) A brain injury caused by lack of oxygen to the brain
B) An alteration in brain function, or other evidence of brain pathology, caused by an
external force
C) A brain injury resulting from exposure to toxins
D) A progressive neurodegenerative disorder
Correct Answer: B
Explanation: Traumatic Brain Injury is specifically defined as an alteration in brain
function or other evidence of brain pathology caused by an external force. This can
occur through two primary mechanisms: trauma impact and traumatic inertial forces.
This definition excludes injuries from lack of oxygen, toxins, or degenerative conditions,
which are classified as non-traumatic brain injuries .
Question 3
What are the two mechanisms of Traumatic Brain Injury?
A) Open and closed head injuries
B) Trauma impact and traumatic inertial forces
C) Penetrating and non-penetrating injuries
D) Primary and secondary injuries
Correct Answer: B
Explanation: TBI occurs through two primary mechanisms: trauma impact (direct
contact force to the head) and traumatic inertial forces (forces that cause the brain to
move within the skull, leading to shearing and stretching of neural tissues). Both
mechanisms can cause significant brain damage and functional impairment .
Question 4
Non-traumatic brain injury can be caused by which of the following?
A) Impact from a fall
B) Motor vehicle accident
C) Lack of O2, decreased nutrients to cells, exposure to toxins, or pressure from tumor
D) Sports-related concussion
,Correct Answer: C
Explanation: Non-traumatic brain injuries result from internal factors rather than
external force. These include lack of oxygen to the brain (hypoxia/anoxia), decreased
nutrients to cells, exposure to toxins, pressure from tumors or blockages, or other
neurological disorders. Unlike TBI, these injuries are not caused by external physical
force .
Question 5
What is the prevalence of Acquired Brain Injury (ABI) in the United States?
A) The most prevalent disability
B) The second most prevalent disability, affecting approximately 13.5 million Americans
C) The third most prevalent disability
D) Affects fewer than 5 million Americans
Correct Answer: B
Explanation: Acquired Brain Injury is the second most prevalent disability in the United
States, with approximately 13.5 million Americans affected. This highlights the significant
public health impact of brain injury and the importance of professionals trained in brain
injury care .
Question 6
In children under 2 years old, what is the leading cause of TBI-related deaths?
A) Falls
B) Motor vehicle accidents
C) Non-accidental trauma
D) Sports injuries
Correct Answer: C
Explanation: Non-accidental trauma is the cause of 80% of deaths in children under 2
years old with TBI. Additionally, two-thirds of children under 3 years old who are abused
have TBIs. Falls cause approximately half of TBI cases in children aged 0-14 years .
, Question 7
What percentage of women in domestic violence situations have been found to have TBI
symptoms?
A) 25%
B) 45%
C) 67%
D) 80%
Correct Answer: C
Explanation: Research indicates that 67% of women in domestic violence situations had
TBI symptoms. This underscores the importance of screening for brain injury in domestic
violence survivors and the need for specialized care approaches in this population .
Question 8
Which of the following criteria is characteristic of a Mild TBI?
A) Loss of consciousness greater than 24 hours
B) GCS score of 3-8
C) Loss of consciousness less than 30 minutes and GCS 13-15
D) Focal findings on CT scan
Correct Answer: C
Explanation: Mild TBI (concussion) is characterized by loss of consciousness for less
than 30 minutes, loss of memory for less than 24 hours, GCS score of 13-15, normal CT
or MRI findings, and any alteration of mental status at the time of the incident. While
considered "mild," these injuries can still cause significant persistent symptoms .
Question 9
What GCS score range indicates a Moderate TBI?
Question 1
What is the definition of an Acute Brain Injury?
A) An injury to the brain that is hereditary or congenital
B) An injury to the brain that is not hereditary, congenital, degenerative, or induced by
birth trauma
C) An injury caused exclusively by external force
D) A degenerative neurological condition
Correct Answer: B
Explanation: An acute brain injury is defined as an injury to the brain that is not
hereditary, congenital, degenerative, or induced by birth trauma. This distinguishes it
from conditions like Alzheimer's disease or developmental disorders, and encompasses
both traumatic and non-traumatic causes .
