Answer to Question 1

ANS: A
Chronic peripheral vascular disease, trauma to the periosteum, and microorganisms that harbor in a hematoma or soft tissue, are associated with the incidence of osteomyelitis.

Answer to Question 2

ANS: D
The fiberglass cast is lighter and thinner, yet stronger, than a plaster cast and is more porous, providing better ventilation. The outside may get wet without deterioration. X-rays penetrate synthetic materials better than they do plaster to evaluate the healing process. A combination of plaster and synthetic resin on a gauze backing produces a thinner, more waterproof cast that weighs less and is as strong as a plaster cast.
