Surgery (FLS) exam 75 QUESTIONS
AND ANSWERS 2025-2026
Most scopes rely on what rod lens system?
Hopkins
How does the Hopkins rod lens system work?
Reflected light is transmitted to coupler to light sensitive
imaging chip in the camera head
As scope angle increases, light transmitted ___________
decreases
,As length increases, light transmitted ________
decreases
What degree of scope is ideal for working in the pelvis and high in
the mediastinum
0 degree
What do you do if your image is blurry?
Look at fiber-optics
Black spots = damage
Assess for moisture
Why is CO2 used in laparoscopy
Inexpensive
Not combustive
May not need tank
, What happens if you warm CO2
Postop body temp and pain increases
How do you avoid losing pneumoperitoneum from suction?
Fully immersing suction tip in fluid being suctioned
When is the picture in picture effect helpful on the camera control
unit
Hysteroscopy
CBD exploration
Concomitant US
If measured pressure is same as preset pressure
Patient may not be significantly relaxed (sign: rhythmic
