Answer to Question 1

C
Although the newer synthetic casts are more expensive than plaster of Paris, they can withstand contact with water without crumbling. A plaster of Paris cast has multiple rolls of open-weave cotton saturated with calcium sulfate crystals. These casts are heavier than synthetic casts and take 24 to 72 hours with no weight bearing or application of pressure while drying. Synthetic casts are lightweight, set in 15 minutes, and can sustain weight bearing or pressure in 15 to 30 minutes.

Answer to Question 2

C
Enteral nutrition, commonly called tube feeding, is the administration of nutrients through the gastrointestinal tract when a patient cannot ingest, chew, or swallow, but can digest and absorb nutrients. Nasoenteric tubes are contraindicated in patients with facial trauma, prolonged bleeding, and upper gastrointestinal (GI) blockage (as is seen in cases of solid cancer).
