- A.
  
  Duration of radiofrequency use.
- B.
  
  Distance of radiofrequency probe from application point.

9.

AMBIENT COBLATION wands automatically deactivate when the temperature alarm threshold is reached.
- A.
  
  True
- B.
  
  False
10.

What is the origin and definition of the word COBLATION?
- A.
  
  Controlled ablation - A heat-driven process using bipolar RF energy in conjunction with a conductive medium, such as saline, to create a highly focused plasma layer with high current dissipation resulting in tissue removal.
- B.
  
  Controlled ablation - A chemical etching process using bipolar RF energy in conjunction with a conductive medium, such as saline, to create a highly focused plasma layer that contains energy sufficient to break the molecular bonds within tissue. This provides precise, volumetric tissue removal.
- C.
  
  Controlled ablation - A non-heat driven process using monopolar radiofrequency energy in conjunction with a non-conductive medium to create a large plasma layer between the tip of the Wand and the tissue to break the molecular bonds resulting in tissue removal.
11.

  True
- B.
  
  False
