tests Flashcards
what test is used to assess arterial insufficiency?
capillary refill time
>3sec = abnormal
what tests assesses risk for pressure injury?
braden scale
15-18=mild
13-14 = mod
10-12= high
<9 = very high
the HBA1c test is used for?
diagnosing DM and for glucose control
normal 4-5.6%
DM = >6.5%
The ABI is used for?
assess if vessels are blocked = poor circulation
<0.5 = severe arterial disease
rubor of dependency checks for?
ischemia
elevate leg and observe for pallor
return leg to WBing
normal = color return w/in 15sec
severe ischemia = >30sec and is red
Stemmer’s sign
used to assess for lymphedema by pinching skin of dorsal 2nd digit and assess if able to lift
theory behind estim & indication
inc blood flow, changes cell polarity, dec edema
Stage III & 4 PI; chronic wounds
precaution & contraindication to e-stim
precaution: <3yo, impaired sensation
contraindication: osteomyelitis; pacemaker
theory behind ultrasound & indication
promote membrane permeability and cavitation
(debridement)
DM PI, venous wounds
precaution & contraindication for ultrasound
precaution: acute inflamm; epiphyseal plate fx
contra: pacemaker; osteomyeltiis; acute DVT
Pulsed lavage theory & indication
wound cleansing and promotion of perfusion
infected wounds or have lots of exudate
precaution & contraindication for pulsed lavage
precaution: pt on anticoagulants
contraindication: exposed nerves/tendons
hyperbaric chamber indication and theory
increase dissolved O2 in plasma to promote angiogenesis and healing
gas gangrene; osteomyelitis
precaution & contraindication for HBO
prec: emphysema; high fever
cont: untreated pneumothorax or on cancer meds
Negative pres. wound therapy theory & indication
removes fluid and increases cell proliferation
chronic wounds and arterial/venous wounds
