Which statement best describes the pathophysiology of osteoarthritis?

Select one of the following:

  • Osteoarthritis may reflect excessive release of enzymes that break down articular cartilage.

  • Osteoarthritis is characterized by inflammation of the joint capsule and excessive production of synovial fluid.

  • Osteoarthritis results from infection of the joints by bacteria or viruses.

  • Osteoarthritis is primarily caused by autoimmune reactions targeting the synovial membrane.

What is true of gouty arthritis?

Select one of the following:

  • It typically affects joint at base of big toe and in untreated gouty arthritis, bone ends fuse and immobilize joint

  • Deposition of uric acid crystals in joints and soft
    tissues, followed by inflammation

  • Treatment: drugs, plenty of water, avoidance of alcohol and foods high in purines (such as liver, kidneys, and sardines)

  • All of the above

Explanation

Question 86 of 94

How do you treat rheumatoid arthritis?

Select one of the following:

  • Steroidal and nonsteroidal anti-inflammatory drugs to decrease pain and inflammation

  • Disruption of destruction of joints by suppressing immune system which slows the autoimmune reaction. Some agents target tumour necrosis factor to block action of inflammatory chemicals

  • Can replace joint with prosthesis

  • All of the above

Explanation

Question 87 of 94

1

What is the first step of rheumatoid arthritis?

Select one of the following:

  • Inflammation of synovial membrane (synovitis) of affected joint

  • Inflammatory blood cells migrate to joint, release inflammatory chemicals that destroy tissues

  • Synovial fluid accumulates, causing joint swelling

  • Inflamed synovial membrane thickens into abnormal pannus tissue that clings to articular cartilage

Explanation

What is the second step of rheumatoid arthritis?

Select one of the following:

  • Inflammatory blood cells migrate to joint, release inflammatory chemicals that destroy tissues

  • Synovial fluid accumulates, causing joint swelling

  • Inflamed synovial membrane thickens into abnormal pannus tissue that clings to articular cartilage

  • Pannus erodes cartilage, scar tissue forms and connects articulating bone ends (ankylosis)

Explanation

What is the third step of rheumatoid arthritis?

Select one of the following:

  • Synovial fluid accumulates, causing joint swelling

  • Inflamed synovial membrane thickens into abnormal pannus tissue that clings to articular cartilage

  • Pannus erodes cartilage, scar tissue forms and connects articulating bone ends (ankylosis)

  • Inflammation of synovial membrane (synovitis) of affected joint

Explanation

Question 90 of 94

What is the fourth step of rheumatoid arthritis?

Select one of the following:

  • Inflamed synovial membrane thickens into abnormal pannus tissue that clings to articular cartilage

  • Pannus erodes cartilage, scar tissue forms and connects articulating bone ends (ankylosis)

  • Inflammation of synovial membrane (synovitis) of affected joint

  • Inflammatory blood cells migrate to joint, release inflammatory chemicals that destroy tissues

Explanation

Question 91 of 94

1

What is the last step of rheumatoid arthritis?

Select one of the following:

  • Pannus erodes cartilage, scar tissue forms and connects articulating bone ends (ankylosis)

  • Inflammation of synovial membrane (synovitis) of affected joint

  • Inflammatory blood cells migrate to joint, release inflammatory chemicals that destroy tissues

  • Synovial fluid accumulates, causing joint swelling

Explanation

Question 92 of 94

1

What is pannus tissue?

Select one of the following:

  • Healthy cartilage found in joints.

  • Scar tissue formed after joint replacement surgery.

  • Abnormal tissue growth in the synovial lining of joints.

  • Fibrous tissue connecting muscle to bone.

Explanation

Question 93 of 94

1

What is ankylosis?

Select one of the following:

  • Inflammation of the synovial membrane.

  • Abnormal bone fusion, leading to stiffness and immobility of a joint.

  • Degeneration of articular cartilage.

  • Excessive release of enzymes that break down articular cartilage.

Explanation

Question 94 of 94

1

What is untrue of rheumatoid arthritis?

Select one of the following:

  • Chronic and inflammatory

  • Has a known cause

  • Is an autoimmune disease (immune system attacks own cells)

  • Signs and symptoms include joint pain and swelling (usually bilateral), anemia, osteoporosis, muscle weakness, and cardiovascular problems
