(904-5)

21
Q

Why is it important to understand the relationship between the three collisions and how they aid with patient assessment/treatment?

A

They help to create an index of suspicion for the severity of the trauma and to give proper treatment

22
Q

Give an example of the second collision of a motor vehicle crash.

A

Lower extremity fractures - Knee into dashboard

Rib fractures - Rib cage into steering wheel

A

Tertiary

26
Q

When should SAMPLE history and the secondary assessment be performed, when caring for a critical trauma patient?

A

On the ambulance

27
Q

A

Force or energy that impact a persons bod

32
Q

What are the four types of blast injuries:

A

Primary: Injuries do to the blast wave itself

Secondary: Injuries to the body results from being struck by flying debris

Tertiary: These injuries occur when the patient is hurled by the force of the explosion against a stationary object

Quaternary: Misc. injuries includes burns from hot gases or fires started by the blast

A

Subarachnoid Space

(1042)

34
Q

Explain how the nervous system responds to an irritating stimulus, such as touching a heated surface.

A

A sensory nerve detects the stimulus and sends a direct message to the motor nerve to pull away from the heat (1043)

Occurs after falls or injuries involving strong deceleration forces

(1050)

40
