1. Electricity always seeks:

the path of most resistance to return to earth ground.
the path of most resistance to return to its source.
the path of least resistance to return to earth ground.
the path of least resistance to return to its source.

current, circuit, resistance and voltage.
current, ground, current and voltage.
current, resistance, hertz and voltage.
current, circuit, ground and amperage.

3. Neuromuscular stimulation from the flow of alternating electric current ceases at frequencies above

50,000 cycles per second.
100,000 cycles per second.
200,000 cycles per second.
350,000 cycles per second.

4. When current concentration/density is high

the resistance is reduced.
the resistance is unaffected.
heat is produced.
heat is dissipated.

5. A patient return electrode is not required when using bipolar electrosurgery because

the voltage is too low to cause an injury.
the voltage is confined to the target tissue.
the current is confined between the two poles of the instrument.
the current disperses in the tissue at the tip of the instrument.

6. As the current concentration is increased

the power setting requirement is decreased.
the power setting requirement is increased.
the heat produced in the tissue remains the same.
the heat produced in the tissue is decreased.

7. The cutting waveform can be modified to provide simultaneous hemostasis (blended waveform) by

decreasing the voltage and increasing the duty (on/off) cycle.
increasing the voltage and decreasing the duty cycle.
decreasing the voltage and decreasing the duty cycle.
increasing the voltage and increasing the duty cycle.

8. Contact quality monitoring is a system that

constantly monitors the quality of the pad/patient interface.
constantly monitors the quality of the generator/pad interface.
combines isolated and interrogation circuitry to monitor output.
combines isolated and interrogation circuitry to monitor resistance.

9. The hazards associated with endoscopic electrosurgery use include all of the following except

direct coupling.
current division.
insulation failure.
capacitive coupling.

10. Tissue response technology incorporates a computer-controlled tissue feedback system that

automatically changes the power settings.
automatically reduces the amount of power required.
senses the conductivity of the target tissue.
senses the impedance/resistance of the target tissue.

11. The smoke produced from the electrosurgical device is

not as harmful as laser plume, and need not be evacuated.
not as harmful as laser plume, but should be evacuated.
potentially as harmful as laser plume, and evacuation is recommended.
potentially as harmful as laser plume, and evacuation is optional.

12. The site selected for the patient return electrode should be all of the following except

over a large muscle mass.
as close to the surgical site as possible.
protected from fluid invasion.
close to a pacemaker to divert the current.

13. Tissue fusion technology is incorporated into a specialized electrosurgical generator that combines

modified monopolar electrosurgery with regulated pressure delivery.
