Traumatic Brain Injury

Question 1

is the result of an external force and is of sufficient magnitude to interfere with daily life.

Answer 1

Traumatic Brain Injury

Question 2

is defined as the consequence of direct contact to the head/brain during the instant of initial injury, causing extracranial focal injuries.

Answer 2

Primary Injury

continuation of damage to the brain as a result of physiologic effects of primary injury.

Answer 3

Secondary Injury

Question 4

explains the dynamic equilibrium of cranial contents.

Answer 4

Monro-Kellie Hypothesis

Answer 8

*Linear
*comminuted
*depressed skull fractures

Question 9

is a break in the continuity of the bone.

Answer 9

Simple (Linear) fracture

Question 10

refers to a splintered or multiple fracture line

Answer 10

Question 11

occur when the bones of the skull are forcefully displaced downward.

Answer 11

Depressed Skull Fracture

Question 12

A fracture of the base of the skull is referred to as

Answer 12

Basal Skull Fracture

Question 13

what is the medical management for depressed skull fractures?

Answer 13

Surgery with elevation of the skull and debridement

Question 14

occurs when the head accelerates and then rapidly decelerates or collides with another object

Answer 14

Traumatic Brain injury, closed (blunt)

Question 15

occurs when an object penetrates the skull, enters the brain, and damages the soft brain tissue in its path.

Answer 15

Traumatic brain injury, open (penetrating)

Question 16

Focal injuries include

Answer 16

contusions and several types of hematomas

Question 17

what are major diffuse injuries?

Answer 17

Concussion and Diffuse Axonal Injury (DAI)

Question 18

This brain injury is when the brain is bruised and damages in a specific area because of severe acceleration-deceleration force or blunt trauma.

Answer 18

Contusion

Question 19

are collections of blood in the brain

Answer 19

Intracranial Hematomas

Question 20

After a head injury, blood may collect in the epidural space between the skull and the dura mater.

Answer 20

Epidural Hematoma

Question 21

is a collection of blood between the dura and the brain, a space normally occupied by a thin cushion of fluid.

Answer 21

Subdural Hematoma (SDH)

Question 22

is bleeding into the parenchyma of the brain

Answer 22

Intracerebral Hemorrhage

Question 23

is a temporary loss of neurologic function with no apparent structural damage to the brain.

Answer 23

Concussion

Question 24

results from widespread shearing and rotational forces that produce damage throughout the brain.

Answer 24

Diffuse Axonal Injury (DAI)

Question 25

are the main neuroimaging diagnostic tools

Answer 25

CT and MRI scans

Question 26

are the most commonly used sedative agents which di not affect cerbral blood flow or ICP.

Answer 26

Benzodiazepines

Question 27

It is an ultrashort-acting, rapid-onset drug with elimination half-life of less than an hour.

Answer 27

Propofol
