Q

Some surgical treatments for Parkinson’s?

A
  1. Destructive (includes thalamotomy and pallidotomy)

2. DBS (preferred): thalamic reduces tremor on contralateral side, while pallidal controls all the cardinal symptoms

Q

Benefits of tilt and space compared to recliner?

A

Patient remains in same position, but orientation in space changes; shear forces are minimized, and pressure re-distributed from seating surface to back support;
get pain relief, can remain seated during weight shifts, can mobilize secretions, smaller turning radius

Q

For adjustable axle, what happens with moving it forward?

A

Allows for more efficient wheelchair propulsion; also can do wheelies

  1. Less rolling resistance
  2. Less energy to propel
  3. Smaller the turning radius
  4. Less stable the chair

Q

Better tire for carpeting, pneumatic or solid rubber tires?

A

Pneumatic (carpeting increases rolling resistance by factor of 4; the tires provide cushioning for outdoor use)

20
Q

Advantages for camber?

A
  1. Maximize lateral stability of the WC
  2. Low degrees of camber make WC easier to propel
  3. Protects hands of user
21
Q

What does a smaller caster mean for WC?

A

Smaller turning radius, does poorly on outdoor surfaces and carpets as it can get stuck

22
Q

Moving caster placement more posterior

A
  1. decreases turning radius
  2. increases maneuverability
  3. decreases stability
23
Q

How are footrests measured? How far off the floor should they be?

A

Distance from heel to under surface of thigh at popliteal fossa;
should have 2 inches of clearance from the floor

24
Q

What is the most common cause of osteomalacia?

A

Vitamin D deficiency

25
Q

What is the female athlete triad?

A

Disordered eating, menstrual disorders, low BMD

26
Q

Gold standard for bone mineral density measurement testing?

A

DEXA

27
Q

Calcitonin acts through what mechanism?

A

Inhibits osteoclastic activity;

can decrease pain in acute compression fx

28
Q

Burns are number ___ cause of accidental death for those under age of 2; What about for ages 4 and 19 or less, respectively?

A

1;
2;
3

29
Q

Inflammatory mediators released upon thermal injury

A
  1. Histamine
  2. Prostaglandins
  3. Thromboxane
  4. Catecholamines
30
Q

Rule of nines for burns

A
Head = 9% BSA;
Each UE = 9%;
Each LE = 18%;
Anterior trunk = 18%;
Posterior trunk = 18%;
Perineum = 1% BSA
31
Q

Consequences of burn injury if epidermis compromised?

A
  1. Decreased protection
  2. Increased water loss
  3. Microorganism growth
  4. Entry of noxious agents
  5. Repeated sunburn
32
Q

Splint positioning for elbow burns? Dorsal hand burns?

A

Elbow extended and forearm supinated;
Wrist in 15-20 degrees extension, MCP in 60-70 degrees flexion, PIP and DIP in full extension; thumb in slight IP flexion and palmar abduction

33
Q

Should splinting be prescribed for exposed tendons and joints?

A

Yes

34
Q

Most common site of HO in adults after burns?

A

Elbows, followed by shoulder

35
Q

Management for MRSA furunculitis in burn patient?

A

I&D, may need abx

36
Q

How long should compression garments be worn on burn sites and at what pressures?

A

23 hr/day at least, need at least 25 mmHg

37
Q

Difference between comparative and non-comparative justice?

A

Comparative: allocation of resources based on needs or wants;
non-comparative: favors equal share over individual needs
