Answer to Question 1

ANS: C
Only moist sponges should be kept on the field while the ESU is in use. Dry sponges can ignite. A suction evacuator device should be placed as close to the source of plume as possible to maximize the evacuation of smoke and enhance visibility at the surgical site.

Answer to Question 2

ANS: D
The continuous or pulsed wave of the Nd:YAG laser penetrates deeper into tissues than do other lasers. It coagulates large vessels up to 4 mm and has the most powerful coagulating action of all the surgical lasers.
