Answer to Question 1

ANS: C
The surgeon may ask the anesthesia provider to insert a tube during an intraabdominal procedure for one of the following purposes: decompression of the gastrointestinal tract, relief of distention that obstructs the view of the surgical site, measurement of blood loss from gastric hemorrhage, or evacuation of gastric secretions during intestinal anastomosis.

Answer to Question 2

ANS: D
When moderate to heavy drainage is expected, a complete dressing consists of at least three layers: (1) contact layer, (2) intermediate layer, and (3) outer layer. The contact layer is a passageway for secretions and exudates; it may be occlusive, semiocclusive, or nonocclusive. The intermediate layer absorbs secretions passing through the contact layer. The outer layer holds the other two layers in position.
