Q

What are some Positive and Negative effects to Foam Cushions?

A

Pos: inexpensive and can be cut to make adjustments

  • have a Protective Surface: to prevent moisture from entering foam
  • new foams can adapt to any shape and still provide support and spread pressure evenly

Neg: doesnt last long (foam wears out faster and loses shape) which allows for pressure points to form
-“wear- cracks” can develop in Protective Coating allowing for moisture + odour

Q

What are some Positive and Negative effects to Thermoplastics?

A

Pos: Honeycomb cushion, made of thermoplastic material distribute weight uniformly over a wide area

  • flexible, stable structure
  • provides pressure reduction and shock absorption
  • have antibacterial and antifungal properties
  • has good ventilation system; circulates air and evaporates moisture= ensuring cool/dry comfort
  • easy maintenance

Neg: -more expensive than foam don’t have as wide variating in density
-can develop sores because its plastic

Q

What are some Positive and Negative effects to Gel cushions?

A

Pos: excellent pressure distributor, and comfortable

Neg: not good “shock” absorber (ex. going over curbs, doesnt provide additional impact support)

  • HEAVY (cancels out benefits for light wheelchair)
  • gel “bottoms-out” and gel is pushed aside; gel needs to be kneeded daily for evenly spreading
  • gel cushions can leak

Q

What are some Positive and Negative effects to Gel cushions?

A

Pos: consists of compression cut foam and gel top layer
-comes with outer and inner “incontinent proof cover” ; increases air flow and breathability

Neg: not suitable for stage 3+4 wound, less shock absorbancy
-adds weight

Q

Basic description of Air/Dry Floatation (ROHO) Cushions

A

There is a LOW and a HIGH profile Roho

  • supports body entirely on air
  • pressure evenly spread against skin
  • air flotation cushions cant “bottom-out” like gel cushions do because its a closed system

16
Q

Why is a ROHO cushion suitable for stages 3+ 4

A

It is very SOFT

17
Q

What are some Positive and Negative effects to ROHO cushions?

A

Pos: lightweight

  • waterproof
  • minimize pressure at bony protrusions

Neg: less stable for those with unstable trunk control

  • roho can be punctures, but patching them is easier than gel
  • Biggest complication; require more MAINTENANCE (need to have pressure frequently checked)
18
Q

What is a method how you could find leak for ROHO cushions

A

-submerge under water and look for escaping air bubbles

19
Q

How much does the Veralite cushion cost?

A

300

20
Q

Basic descriptions of the Veralite cushion

My favourite

A

-3 layers of foam for:
>support and prevention of “bottoming-out”
>includes an air cushion layer for pressure management
-has diff. choices of valves and cushion covers
-doesnt require air pumps, kneeding or manipulation
-easy to use

21
Q

Which clients is the Veralite designed for?

A

-clients with cognitive awareness and sensation; need to be able to adjust the valve

22
Q

What are some Positive and Negative effects for the Veralite cushions?

A

Pos: provide VARYING levels of support (soft/medium/firm foam layers)

  • easy to use
  • doesnt need to be pumped up in order to inflate

Neg: cognitive awareness is needed (need to know how much air to release)
-sensation and proprioceptive awareness is necessary to determine optimal positioning and comfort

23
Q

How to use Veralite valve?

A
  • turn counter clockwise
  • stand up for cushion to fully inflate
  • once seated need to manually monitor how much air is needed (sink down to 1-2 inches) under their prominent areas
  • close valve
24
Q

How do you test for appropriate air level in cushions?

***DO NOT OVER-INFLATE

A

-palmar up to find ischial tuberosity (sit bones)

25
Q

What is the purpose of a ‘Foot Drop Splint’ and what do you have to do before putting it on

A
  • prevent/correct plantar flexion contractures and inversion/eversion
  • PROM: Dorsi/Plantar flexion on affected foot which will prepare for positioning into splint
26
Q

What happens if the knee is extended?

ps: always have leg slightly flexed when applying splint

A

Foot wants to extend (plantar flex) which increase spasticity (NOT GOOD)

27
Q

Foot splints are not to be used during ____

A

ambulation

28
Q

What is the function of the toe pad, rotation bar, and rubber sole plate

A

toe pad: keep bed sheats away to prevent spasticity
rotation bar: prevent internal/external rotation of hip (ex. after surgery)
-rubber sole plate: short transfers

29
Q

What are three common IV infusion sites and specific location for each

A
  • Dorsam of hand: thumb area: dorsal veinous complex
  • Dorsam of foot: dorsal veinous complex of foot
  • Scalp
30
Q

Why is it importatnt to have IV bag above heart level

A

to prevent reflux of fluid

31
Q

3 complications for IV therapy

A
  1. kink
  2. prolonged position: flow fluid is blocked
  3. infusion site need to be kept above heart level (when ambulating)
32
Q

What is Erythema:

A

superficial reddening of skin from irritation/injury causing dilation of capillaries

33
Q

What are three types of Catheters

A
  1. Foley catheter (indwelling)
  2. External catheter
    * *3. Suprapubic (under skin at belly button)
34
Q

What are some skin integrity products

A
  • posey foot elevator (round)
  • posey cushioned heel protectors
  • sheepskin heel protectors
35
Q

Why do we use “slider tubes”/transition-slider sheet

A

to promote independence
