Answer to Question 1

ANS: A
The Salem sump tube is preferable for stomach decompression. The Salem sump tube has two lumina: one for removal of gastric contents and one to provide an air vent. When the main lumen of the sump tube is connected to suction, the air vent permits free, continuous drainage of secretions. While the Levin tube can be used for decompression, it is only a single-lumen tube with holes near the tip. Large-bore tubes, 12 Fr and above, are usually used for gastric decompression or removal of gastric secretions. Fine- or small-bore tubes are frequently used for medication administration and enteral feedings.

Answer to Question 2

ANS: C
A cathartic is a laxative that stimulates a bowel movement. It would be effective if the patient experiences a bowel movement. The other options are not outcomes of administration of a cathartic. An antidiarrheal will provide relief from diarrhea. Pain medications will provide pain relief. Carminative enemas provide relief from gaseous distention (flatulence).
