FUNDAMENTALS OF LAPAROSCOPIC SURGERY QUESTIONS AND ANSWERS
Most scopes rely on what rod lens system? - CORRECT ANSWER✅✅Hopkins
How does the Hopkins rod lens system work? - CORRECT ANSWER✅✅Reflected light is transmitted to
coupler to light sensitive imaging chip in the camera head
As scope angle increases, light transmitted ___________ - CORRECT ANSWER✅✅decreases
As length increases, light transmitted ________ - CORRECT ANSWER✅✅decreases
What degree of scope is ideal for working in the pelvis and high in the mediastinum - CORRECT
ANSWER✅✅0 degree
What do you do if your image is blurry? - CORRECT ANSWER✅✅Look at fiber-optics
Black spots = damage
Assess for moisture
Why is CO2 used in laparoscopy - CORRECT ANSWER✅✅Inexpensive
Not combustive
May not need tank
What happens if you warm CO2 - CORRECT ANSWER✅✅Postop body temp and pain increases
How do you avoid losing pneumoperitoneum from suction? - CORRECT ANSWER✅✅Fully immersing

If measured pressure is same as preset pressure - CORRECT ANSWER✅✅Patient may not be
significantly relaxed (sign: rhythmic abdominal muscle contractions)
Mechanical obstruction - kink in tubing, standing on tubing
Low pressure, high flow rate - CORRECT ANSWER✅✅Make sure connected to port, check ports to make
sure closed, check ports for leaking, check distention of bowel or foley
Low pressure, no flow - CORRECT ANSWER✅✅Standby mode
Check gas level
Blank monitor - CORRECT ANSWER✅✅NOT camera fog
Check cords
Benefits and risks of bipolar current - CORRECT ANSWER✅✅Current flows through smaller tissue
volume - less risk of lateral tissue damage and necrosis
Risk of cutting vessels before sealing
Improper device function
Which current type does not require dispersive electrodes - CORRECT ANSWER✅✅Bipolar
At what temperature does protein denaturation occur? - CORRECT ANSWER✅✅Over 60 degrees celsius
