Question 1: What is the primary clinical objective during the acute
hospital phase immediately following a traumatic brain injury?
A. Initiating community reintegration planning
B. Preventing secondary brain injury and stabilizing vital functions
C. Beginning intensive cognitive remediation therapy
D. Establishing vocational training goals
CORRECT ANSWER: B. Preventing secondary brain injury and
stabilizing vital functions
Rationale: The acute care phase focuses on medical stabilization,
maintaining vital functions, managing intracranial pressure, and preventing
further neurological deterioration. Rehabilitation and community
integration occur in subsequent post-acute settings.
Question 2: Which Glasgow Coma Scale (GCS) score range is
characteristic of a severe traumatic brain injury?
A. 13 to 15
B. 9 to 12
C. 3 to 8
D. 15 to 18
CORRECT ANSWER: C. 3 to 8
Rationale: Severe TBI is clinically defined by a GCS score of 3 to 8.
Moderate TBI falls within 9 to 12, while mild TBI (concussion) is classified
as 13 to 15.
Question 3: A patient exhibits profound personality changes,
disinhibition, and difficulty planning future actions. Which lobe of the
brain is most likely injured?
A. Parietal lobe
B. Occipital lobe
,C. Frontal lobe
D. Temporal lobe
CORRECT ANSWER: C. Frontal lobe
Rationale: The frontal lobe is responsible for executive functions such as
planning and organization, as well as personality regulation and inhibition.
Damage to this region leads to the described symptoms.
Question 4: Which brain structure serves as the primary relay station
for sensory information (except smell) to the cerebral cortex?
A. Hypothalamus
B. Thalamus
C. Pons
D. Reticular formation
CORRECT ANSWER: B. Thalamus
Rationale: The thalamus acts as the brain's major sensory relay
switchboard. Nearly all sensory pathways (visual, auditory, somatosensory,
and gustatory) synapse in the thalamus before projection to the cerebral
cortex, with the exception of olfactory pathways.
Question 5: Damage to the hippocampus, located in the medial
temporal lobe, primarily results in which deficit?
A. Inability to coordinate voluntary movement
B. Difficulty forming new memories (anterograde amnesia)
C. Loss of visual field (hemianopsia)
D. Inability to comprehend language
CORRECT ANSWER: B. Difficulty forming new memories (anterograde
amnesia)
Rationale: The hippocampus is crucial for consolidation of short-term
memory into long-term memory. Damage to this structure leads to
anterograde amnesia, which is the inability to form new memories.
Question 6: An inability to recognize one's own personal deficits or
functional disabilities resulting from a brain injury is clinically referred
to as:
,A. Aphasia
B. Anosognosia
C. Apraxia
D. Agnosia
CORRECT ANSWER: B. Anosognosia
Rationale: Anosognosia is the clinical term for unawareness or denial of
one's own neurological deficit or disability. It is distinct from aphasia
(language impairment), apraxia (motor planning deficit), and agnosia
(failure to recognize objects).
Question 7: A "coup-contrecoup" injury pattern refers to:
A. Injury exclusively within the brainstem and cerebellum
B. Injury only at the site of skull impact
C. Injury at the site of impact and on the opposite side due to brain
rebounding
D. Injury along the internal capsule and basal ganglia
CORRECT ANSWER: C. Injury at the site of impact and on the opposite
side due to brain rebounding
Rationale: A coup injury occurs directly beneath the site of impact,
whereas a contrecoup injury occurs on the side opposite the impact as the
brain rebounds within the skull. This pattern is common in acceleration-
deceleration injuries.
Question 8: Which cerebral lobe contains the primary visual center?
A. Frontal lobe
B. Parietal lobe
C. Occipital lobe
D. Temporal lobe
CORRECT ANSWER: C. Occipital lobe
Rationale: The occipital lobe is located at the posterior region of the brain
and houses the primary visual cortex, which is responsible for processing
visual information.
Question 9: What is the primary function of the reticular activating
system (RAS)?
, A. Motor control and coordination
B. Arousal, wakefulness, and consciousness
C. Temperature regulation
D. Hunger and satiety
CORRECT ANSWER: B. Arousal, wakefulness, and consciousness
Rationale: The RAS is a network of neurons in the brainstem that regulates
wakefulness, arousal, and sleep-wake transitions. Damage to this system
can result in coma or persistent vegetative state.
Question 10: An Acquired Brain Injury (ABI) is defined as an injury that:
A. Is induced by birth trauma
B. Occurs after birth and is not hereditary, congenital, or degenerative, and
includes TBI
C. Excludes traumatic brain injury
D. Is exclusively caused by external physical force
CORRECT ANSWER: B. Occurs after birth and is not hereditary,
congenital, or degenerative, and includes TBI
Rationale: ABI encompasses any injury to the brain that occurs after birth
and is not related to hereditary, congenital, or degenerative conditions. It
includes both traumatic brain injuries (TBI) and non-traumatic causes such
as stroke, anoxia, or tumor.
Question 11: Which structure is responsible for maintaining balance
and coordination?
A. Medulla oblongata
B. Cerebellum
C. Corpus callosum
D. Amygdala
CORRECT ANSWER: B. Cerebellum
Rationale: The cerebellum coordinates voluntary movement, balance, and
posture. The medulla controls vital autonomic functions, the corpus
callosum connects hemispheres, and the amygdala processes emotion.
Question 12: A patient who exhibits fluent speech that lacks
meaningful content and has impaired comprehension is most likely
experiencing damage to:
