A
  • close nearby doors and draw curtains
  • wash hands each time you see a patient
  • drap patient with gown or sheet

Q

A
  • Ability to ID an object by feeling it
  • Place a familiar object in hand and have patient tell you what it is

A

sling and swather

38
Q

Sling without swather for

A

clavicle fractures

39
Q

What does the sling and swathe do

A

Sling supports weight of arm and swather holds arm against chest to minimize shoulder motion

40
Q

When do we give a cast

A

5-7 days after injury and swelling has resolved

41
Q

TOC for nonoperative fractures

42
Q

How long do we keep a cast on? When do we change it?

Q

How much padding for casting

A

2 layers UE, 3-4 layers LE

44
Q

Goal of molding cast

A

maintain alignment of fracture

45
Q

What shape is best to maintain fracture alignment

A

elliptical

46
Q

3 point molding

A
  • 1st point over apex of fracture with force directed opposite direction of fracture to displace
  • two remaining points lie on opposite side of bone at either side of apex
47
Q

injury at C1/C2

73
Q

When assess c-spine films what are we looking at in soft tissue

A

Preverebral swelling, especially at C2-C3 (more than 5mm), and check the predental space, which should be <3mm in adults and <5mm in kids

CT is used to ID

A

vertebral fractures and handling

75
Q

MRI used for

A
  • Evaluation of injury of spinal cord itself or rupture of the intervertebral disc
  • Demonstrate areas of contusion and edemain the cord, as well as areas of compression
76
Q

Important things to do with C-spine injuries

A

proper immobilization and caution handling

77
Q

In a C-spine injury, you may not be able to maintain what? How to treat?

A
  • tidal volume because intercostal muscles are nonfunctional

- monitor respiratoyr status

78
Q

SCIWORA

A
  • spinal cord injuries without radiograph abnormalities

- Children more susceptible because greater elasticity of cervical structures

79
Q

What do we assume if pain perception is altered by alcohol, drugs, head injury, shock or other causes?

A

injury is present

80
Q

AMUST

A

A=Altered mental state. Check for drugs or alcohol.
M=Mechanism. Does the potential for injury exist?
U=Underlying conditions. Are high-risk factors( e.g.,RA) for fxs. present?
S=Symptoms. Is pain or paresthesia part of the picture?
T=Timing. When did the symptoms begin in relation to the event

81
Q

Key questions to guide framing of nervous system exam

A

1) Is the mental status intact?
2) Are your findings symmetric?
3) Where is the lesion?

82
