Question 11

The gas, liquid, or solid through which light energy is passed to create a laser beam, contained within the optical resonant chamber, is known as ________.

Accepted Answer

The laser medium, also known as the gain medium or lasing medium, is the material used in a laser to amplify light by stimulated emission. It can be in the form of a gas, liquid, or solid.

Question 12

Choose from the terms listed and match them with their most correct description. You may use the same answer more than once.
-It may be activated by a switch located on the pencil or by a foot pedal

Accepted Answer

The description refers to the active electrode, which is part of an electrosurgical unit. The active electrode is the part that delivers the electrical current to the surgical site and can be activated by a switch on the device or a foot pedal.

Question 13

Choose from the terms listed and match them with their most correct description. You may use the same answer more than once.
-Its function is to capture electrical current from the active electrode and transmit it back to the power unit.

Accepted Answer

The patient return electrode's function is to capture electrical current from the active electrode and transmit it back to the power unit, completing the circuit.

Question 14

Lasers are distinguished by the functional or biophysical reaction of the ________.

Accepted Answer

Lasers are distinguished by the functional or biophysical reaction of the target tissue, as the specific effects of a laser depend on how the tissue being targeted absorbs and reacts to the laser's energy.

Question 15

Choose from the terms listed and match them with their most correct description. You may use the same answer more than once.
-Open procedures require tips such as a flat blade, Teflon-coated blade, needle point, ball tip, and loop.

Accepted Answer

Active electrodes are used in open procedures and can have various tips like a flat blade, Teflon-coated blade, needle point, ball tip, and loop, depending on the specific surgical needs.

Question 16

___________ is a characteristic of laser energy in which some cells absorb the lasing medium whereas others do not. This characteristic prevents the spread of heat (and damage) outside the target tissue.

Accepted Answer

Selective absorption is the characteristic that allows some cells to absorb the lasing medium while others do not, preventing the spread of heat outside the target tissue. This property is crucial for the precision and safety of laser applications in various fields, including medical treatments.

Question 17

Choose from the terms listed and match them with their most correct description. You may use the same answer more than once.
-To prevent alternate site burns, the current exits the body through this highly conductive electrode.
