1 Before beginning a laparoscopic procedure, why is a white balance performed on the camera system?

To protect the bulb from overheating before insufflation
To ensure accurate color representation during visualization
To align the horizon with the trocar orientation
To prevent fogging within the laparoscope lens

2 During dissection, the surgeon requests a “horizon correction.” What is the correct action for the assistant?

Rotate the light cable gently until the image levels out
Adjust the trocar angle while maintaining pneumoperitoneum
Rotate the camera head to reorient the image
Turn the monitor slightly to correct the view

3 What is the most likely cause when intra-abdominal pressure spikes above 20 mmHg shortly after starting insufflation?

The CO₂ cylinder is low and flow is reduced
The insufflator’s pressure sensor has failed
The insufflation line is kinked or obstructed
A trocar seal is leaking gas into the room

4 During post-procedure cleanup, a scrub nurse reports that several laparoscopic instruments show dull tips and loose hinges. Review of setup reveals that delicate graspers were stored under heavier retractors in the tray. What consequence most likely resulted from this error?

Tip corrosion from inadequate pre-cleaning moisture
Mechanical stress causing misalignment and loss of precision
Cross-contamination from improper instrument labeling
Reduced sterilization efficacy due to excess silicone padding

5 While the laparoscopic image appears dim, the lens and light intensity check normal. What should be assessed next?

The adequacy of insufflation and abdominal distension
The orientation of the camera head
The position of the smoke evacuation filter
The monitor’s brightness settings
