Neurological Trauma and Critical Care Quiz

Falls are a leading cause of traumatic brain injury, especially among the elderly.

The Glasgow Coma Scale is used to assess the level of consciousness in patients with brain injury.

CT scans are commonly used as the initial imaging modality for evaluating acute head trauma due to their ability to quickly visualize intracranial structures.

Focal neurological deficits are not typically associated with diffuse axonal injury, which instead presents with widespread brain damage.

Subarachnoid hemorrhage is characterized by bleeding into the space between the arachnoid membrane and the pia mater surrounding the brain.

Thunderclap headache is a sudden, severe headache associated with subarachnoid hemorrhage and other serious conditions.

Mannitol is commonly used to reduce intracranial pressure in patients with traumatic brain injury by osmotically drawing fluid out of brain tissue.

Visual hallucinations are not typically associated with concussions, which instead may present with symptoms like headache, confusion, and memory problems.

A depressed skull fracture occurs when bone fragments are pushed into the brain tissue, often as a result of significant trauma.

The Monroe-Kellie Doctrine states that the sum of volumes of brain tissue, blood, and cerebrospinal fluid within the skull must remain constant to maintain normal intracranial pressure.

Intracerebral hematoma refers to bleeding within the brain tissue, often as a result of trauma or ruptured blood vessels.

Autonomic dysreflexia is a potentially life-threatening complication of spinal cord injury characterized by a sudden increase in blood pressure due to overactivity of the autonomic nervous system.

A syncopal episode refers to a sudden, transient loss of consciousness and postural tone due to temporary inadequate blood flow to the brain, often resulting from a drop in blood pressure or heart rate.

A spinal epidural hematoma is characterized by bleeding between the dura mater and the spinal cord, often resulting in a convex-shaped hemorrhage.

Intracerebral hematoma refers to bleeding within the brain tissue itself, often due to trauma or ruptured blood vessels.

Diffuse axonal injury often presents with consciousness disturbances, including coma or altered levels of consciousness.
