A 68-year-old woman has had her mobility and quality of life severely affected by rheumatoid arthritis (RA).
 
  Place the following pathophysiological events involved in her health problem in the correct order that they most likely occurred. Use all the options.
  A) Inflammatory response
  B) Interaction between rheumatoid factor (RF) and IgG
  C) T-cell-mediated immune response
  D) Pannus invasion
  E) Destruction of articular cartilage

Question 2

While being tackled, a 20-year-old football player puts out his hand to break his fall to the ground.
 
  Because the intense pain in his wrist did not subside by the end of the game, he was brought to an emergency department where diagnostic imaging indicated an incomplete tear of the ligament surrounding his wrist joint. At the time of admission, his wrist was swollen with a severely restricted range of motion. What will his care team most likely tell the player about his diagnosis and treatment?
  A)
  This strain will likely resolve itself with sufficient rest.
  B)
  You've suffered a severe sprain, and you might need a cast.
  C)
  Your wrist contusion will have to be observed for bleeding under the skin surface.
  D)
  It looks like a mild to moderate sprain, and you'll need to keep it immobilized for a few weeks.

Answer to Question 1

Ans:
C, B, A, D, E

Feedback:

RA is thought to begin with a T-cell-mediated immune response that precipitates interaction between IgG and RF that constitutes an immune response. Pannus invasion is one consequence of this interaction, the ultimate result of which is destruction of cartilage.

Answer to Question 2

Ans:
D

Feedback:

Damage to the ligament structures is associated with sprains, and an incomplete tear would be indicative of a mild to moderate (grade 1 or 2) sprain. A strain is associated most commonly with overuse, and severe sprain would involve total disruption of the ligament.
