Q

What is diffuse axonal injury? What causes it?

A

Leading cause of death from TBI, results from the brain moving back and forth in the skull as a result of rapid acceleration or deceleration. Usual presentation is prolonged unconsciousness.

46
Q

What is Newton’s First Law?

A

An object remains in motion or at rest until it is acted on by an external force. (Inertia)

47
Q

What is Newton’s Second Law?

A

Force = mass * acceleration

48
Q

What is Newton’s Third law?

A

For every action there is an equal and opposite reaction.

49
Q

What factors determine the severity of an electrical injury?

A

Voltage, amperage, current type

50
Q

What is voltage? How does voltage determine electrical injury?

A

Voltage measures flow of electrons

<1000 low (homes = 120-240V, railroad = 600V)

>1000 high (power lines, electrical substations)

Higher more dangerous

51
Q

What is amperage? How does amperage determine electrical injury?

A

Volume of electrons flowing in circuit

Homes 15-30A

Muscle tetany 15-30mA

Dysrhythmias 50-100mA

52
Q

How does current type determine electrial injury?

A

AC produces muscle tetany

Homes 60Hz

Muscle Tetany between 40-110Hz

DC produces a large muscle contraction, pushes victim away

53
Q

Urine output in rhabdomyolysis must be at least

A

100 ml/hr

54
Q

How should dry chemical exposure be managed?

A

Brush chemical off before irrigation.

55
Q

Hydrofluroic acid exposure can cause what complication? How is it managed?

A

Drop in serum calcium levels, and severe pain

Gel made with calcium placed on exposure site, possible IV calcium if EKG changes

56
Q

Escharotomy is a procedure required to treat

A

Circumferential burns to the torso that inhibit breathing

57
Q

What is the different between an escharotomy and a fasciaotomy?

A

Escharotomy cuts through burned/charred skin (circumferential burns).

Fasciaotomy cuts through muscle fascia (compartment syndrome)

58
Q

Signs of a tension pneumothorax include

A

Tachycardia

Hypotension

Anxiety/panic

Torso trauma

59
Q

PEA should be managed by treating the appropriate causes, remembered by what mneumonic?

A

H’s & T’s

60
Q

The most common cause of PEA in trauma is

A

Hypovolemia
