Week 3 Chapter 36 MS Disorders Flashcards
1
Q
Noninflammatory degenerative disorder of the joints
A
Osteoarthritis
2
Q
Most common form of joint disease is sometimes called what?
A
Degenerative Joint disease
3
Q
Osteoarthritis is classified as either what?
A
- Primary - idiopathic - no prior event or disease related to the OA
- Secondary- resulting from previous joint injury or inflammatory disease similar to RA
4
Q
Primary OA does not involve what?
A
Autoimmunity or inflammation
- Can occur as an end result of an autoimmune disorder where joint destruction occurs
5
Q
Limited to the affected joints and no systemic symptoms
A
OA
6
Q
What is the pathophysiology of OA?
A
- Articular cartilage breaks down, leading to progressive damage to the underlying bone and eventual formation of osteophytes( Bone spurs) that protrude into the joint space
- Joint space is narrowed, leading to decreased joint movement and the potential for more damage
- Joint can progressively degenerate
- Previously thought of as simply “ wear and tear” r/t aging
7
Q
Evolution of OA
A
- Bone
- Cartilage
- Thinning of cartilage
- Cartilage remnants
- Destruction of cartilage
8
Q
What can illicit a chondrocyte response?
A
- Mechanical Injury
- Genetic and hormonal Factors
- Previous joint damage
- other
9
Q
With a chondrocyte response what happens next?
A
Release of cytokines
10
Q
What happens after the release of the cytokines?
A
-Stimulation production and release of proteolytic enzymes, metalloproteases, collagenase
Then resulting damage predisposes to further damage
11
Q
Characteristic Degenerative Changes “Degradation”
A
- Cartilage Particles

- Effective coping
- Absence of complications
27
Nursing interventions of RA and OA include

43
Most prevalent bone disease in the world affecting more than 1.5 million osteoporotic fractures each year
Osteoporosis
44
Normal homeostatic bone turnover is altered and the rate of bone resorption is greater than the rate of bone formation resulting in loss of total bone mass
Osteoporosis
