31
Q

T or F. Survivial rates for Aortic Rupture are high?

A

False, most PTs with traumatic aortic rupture will expire at the site of the accident, up to 20% survive in the hospital.

32
Q

Identify 5 S/S of Aortic Rupture

A

Chest Pain (sudden, sharp, stabbing, radiating to shoulder, neck, and jaw), Decreased Sensation, Anxiety, Pallor, Dry Skin (dry mouth/thirst), N/V, Dizziness, SOB

33
Q

Flail Chest

A

Occurs when a segment of the thoracic wall becomes unattached from the rest of the chest wall. Most typically occurs when there are 2 or more ribs fractured, allowing that segment of the thoracic wall to FLOAT independently of the rest of the chest wall

34
Q

T or F. The flail segment is pushed out during inspiration and drawn in during expiration?

A

False, the flail segment is drawn in during inspiration and pushed out during expiration.

35
Q

S/S of Flail Chest include:

A

Paradoxical motion, hypoventilation, dyspnea, guarding, self-splinting, bony crepitus, tachycardia, excruciating pain upon movement.

36
Q

T or F. Flail Chest is the most common life-threatening thoracic injury in America?

A

False, Pulmonary contusion. 30-70% of all victims of blunt force trauma experience it. It is the result of a portion of the lung forcefully impacting onto the chest wall. This condition is commonly assoc. w/ flail chest victims of blunt force trauma, however.

37
Q

What are common S/S of Pulmonary Contusion?

A

Pulmonary edema, Interstitial hemorrhage, Atelectasis, Airway obstruction, Increased pulmonary vasculary resistance (PVR), Intra-alveolar hemorrhage

38
Q

What does increased PVR mean for the heart?

A

It has to work harder

39
Q

Intra-alveolar hemorrhage would indicate:

A

Bleeding in the alveoli; couging will occur

40
Q

In regards to Nursing Management, what interventions can be performed for MINOR flail chest injuries?

A

Supplemental O2, Postural drainage (pulmonary toilet), Bronchoscopy (if PT is unable to remove excessive secretions), Pain Rx, Local anesthetic block, Firm chest wrap.

41
Q

When giving meds to patients with minor flail chest injuries, what’s most important to keep in mind?

A

They should be given to enhance the ability to breathe, but they suppress the respiratory system so continue to mointor PT.

42
Q

In regards to MAJOR flail chest injuries, intubation and ventilation should be considered when:

A

Greater than 3 ribs are fractures or there’s a free floating sternum and/ or when serious compression injury has occured.

43
Q

What are 4 common causes for Head and Spinal Trauma?

A

MVAs, Falls, Stabbings, Firearms.

44
Q

In regards to MVAs, what are 3 types of Collusion impact?

A

Vehicle impact (>40mph), Body impact, Organ impact

45
Q

Frontal injuries caused by MVCs include:

A

Head and neck, back, brain, spine, ribs and clavicle, arms and legs, concussions, soft tissue, internal, dislocations, abrasions, cuts, and bruises.

46
Q

Delayed injuries resulting from Frontal injuries include:

A

HA, blurred vision, dizziness and loss of taste, smell, or hearing. Also, difficulty breathing, blood in urine or stool, swelling, loss of motion and visualized bruising.

47
Q

T or F. When completing a Head-to-Toe assessment on a PT that was involved in a MVC, it’s important to keep in mind that some symptoms may surface slowly?

A

TRUE

48
Q

Head and C-spine injury

A

The combination of the flexion and rotation of the spine that occurs with lateral impact (side impact). Produces more frequent and severe cervicle injuries

49
Q

T or F. Fractures of the spine are more common in frontal injuries?

A

False, fractures of the spine are more common with lateral/ side impact injuries than frontal or rear- end collusions

50
Q

T or F. Chest and abdominal injuries to the side of impact are the same as in head on collusions?

A

TRUE

51
Q

Nursing assessment for Lateral/ Side Impact injuries include:

A

Complete head-to-toe, but special focus needs to be placed on C-spine immobility and potential for cervical and spine injuries.

52
Q

Injuries from Rear impact collusions usually occur:

A

As the torso and seat shoot forward. If the headrest is too low, the neck will end up hyper-extended over the top of the headrest. This is how strains, torn ligaments, and more serious cervical injuries occur.

53
Q

T or F. The nursing assessment after Rear Impact collusions should be focused on the neck and potential cervical injuries?

A

TRUE

54
Q

The severity of Stab wounds depends on:

A

Location penetrated, Blade length, and Angle of Penetration.

55
Q

When assessing a PT with a penetrating wound, what is most important to keep in mind?

A

Don’t underestimate the internal damage of simple entrance wounds; the attacker may have moved the blade around inside the PT.

56
Q

T or F. A gunshot only causes 2 wounds- an entrance and exit wound?

A

False, a gunshot causes 3 wounds. Entrance wound, Exit wound, and Internal wound.

57
Q

Entrance wounds

A

May be round or oval; shots from close range may have burns or smoke marks on the skin

58
Q

Exit wounds

A

If present, it will be larger and may be linear or stellate in appearance; not all entrance wounds have an exit.

59
Q

Internal wounds

A

Damage to the tissue in the direct path of the bullet will cause a permanent cavity; tissue on either side of the bullet’s path will also be injured d/t pressure from energy exerted outward from the path of the bullet which results in a temporary cavity.

60
Q

The temporary cavity resulting from a gunshout wound is usually 3 to 6 times the size of the front surface?

A

TRUE

61
Q

T or F. Wounds caused by stabbings are most often explored more than gunshot wounds?

A

False, 85-95% of wounds caused by firearms will require surgical intervention; only 30% of knife wounds will need to be explored.

62
Q

Who are most at risk for Fall injuries?

A

Children, Adults >55, Elders

63
Q

What is the most common cause of TBI, hip fractures, and other fractures?

A

Falls

Q

Injuries that require Forensic include:

A

Anything that involves criminal activity and has legal requirements. Sexual assault, Physical assault and battery.

65
Q

In regards to Trauma, what assessment criteria is best to follow?

Assess ABCs, Circulatory status, Head-to-Toe, Neurovascular, Neck and Spine immobility

66
Q

Glascow Coma Scale (GCS)

A

an assessment tool created for assessing concussion in primary care and emergency medicine settings.

A

Characteristics of the injury including mechanism LOC, and post-traumatic amnesia; Signs and Symptoms, and Risk factors for prolonged recovery.

A

Test used to document the presence and severity of neurocognitive impairment associated with concussion. It tests for impairment in orientation, immediate memory, concentration, and delayed recall.

A

Subcutaneous bruising around the flanks and umbilicus, suggestive of a RETROperitoneal hematoma

72
Q
