Question 1

What is the primary purpose of a surgical tourniquet system and what safety features must be verified?

Accepted Answer

To restrict blood flow to a limb by applying controlled pressure, with pressure and time monitoring for safety

Answer

Surgical tourniquets restrict blood flow using pneumatic cuffs, with critical safety features including accurate pressure regulation and time monitoring.

Question 2

How does a surgical smoke evacuator work and why is it important in the operating room?

Accepted Answer

It captures and filters surgical plume to protect staff from hazardous airborne particles and chemicals

Answer

Smoke evacuators use ULPA filtration and activated carbon to remove surgical plume containing harmful particles and chemicals.

Question 3

What is the function of an operating room surgical light system and what parameters must be maintained?

Accepted Answer

Provide high-intensity, shadow-free, color-accurate illumination with minimal heat generation

Answer

Surgical lights must provide high intensity (up to 160,000 lux), minimize shadows, and provide accurate color rendering (CRI >85).

Question 4

What is the purpose of the return electrode monitoring (REM) system on an electrosurgical unit?

Accepted Answer

To continuously verify adequate contact of the dispersive electrode pad to prevent burns

Answer

REM monitors impedance between the split-pad sections, alarming and disabling output if contact degrades.

Question 5

What is an operating room integration system and what does it manage?

Accepted Answer

A system that centrally controls video, audio, and data from multiple surgical devices within the OR

Answer

OR integration systems manage routing of video from surgical cameras, audio, room controls, recording, and documentation.
