Electrosurgery

What is the primary purpose of electrosurgery?

• To perform thermal imaging
• To cut and coagulate tissues
• To deliver medication to the patient
• To monitor vital signs

What type of current is used in electrosurgery?

• Direct Current (DC)
• Alternating Current (AC)
• Pulsed Current
• Static Current

What frequency range is typically used for electrosurgical devices?

• 50-60 Hz
• 300-500 kHz
• 1-2 GHz
• 100-200 MHz

What is the standard color coding for the 'Cut' mode button on most electrosurgical units?

• Blue
• Yellow
• Red
• Green

What color is typically associated with the 'Coagulation' mode on electrosurgical generators?

• Yellow
• Blue
• Green
• Red

Which of the following is NOT a common electrosurgical modality?

• Monopolar
• Bipolar
• Laser Ablation
• Argon Plasma Coagulation

What is the main benefit of using blended current in electrosurgery?

• Pure cutting with no coagulation
• Reduced smoke production
• Combination of cutting and coagulation
• Increased precision

What is the main purpose of using coagulation modes in electrosurgery?

• To reduce power consumption
• To achieve hemostasis
• To minimize surgical site contamination
• To increase cutting speed

What is the main risk associated with improper placement of the return electrode in monopolar electrosurgery?

• Insufficient coagulation
• Electrical burns
• Reduced power output
• Device malfunction

Which safety measure is crucial when using argon plasma coagulation (APC)?

• Grounding the patient properly
• Avoiding use near oxygen sources
• Using low-frequency currents
• Applying saline solution continuously
