10mm, 30-45cm
hopkins rod lens - CORRECT ANSWER-light has to travel back through the rod
to capture the image.
decreasing light in the camera for... - CORRECT ANSWER-decreasing diameter,

When is zero degree scope most useful - CORRECT ANSWER-when working in
a small area directly in line with the scope and ports, like the pelvis
how to check fiber optics light connection - CORRECT ANSWER-black dots=
broken fibers
why does it fog up? - CORRECT ANSWER-temperature and humidity
discrepancy between the OR and body
,tools for defogging - CORRECT ANSWER-- FRED antifog (must dry before
putting back in)
- put laparoscope in hot water
methods to clean a smudged lens - CORRECT ANSWER-- gently wipe on clean
tissue (liver, uterus, bowel)
- remove scope and clean with hot water and gauze
Insufflation gas type and reasoning - CORRECT ANSWER-CO2- readily
available, inexpensive, non combustable, warmed and humidified better
other gasses used in laparoscopy - CORRECT ANSWER--nitrous oxide
-helium (inert substance)
why is the CO2 warmed and humidified for laparoscopy? - CORRECT ANSWER-
statistically significant decreases in body temp and post-op pain
(not significant with surgery lasting <90 mins)

,components of the video tower - CORRECT ANSWER--light source
-camera control unit
-video monitor
-insufflator
most common light source - CORRECT ANSWER-300W xenon lamp
troubleshooting steps: gas preOP - CORRECT ANSWER-1. check that co2 tank
is full (gauge may read 'empty' if connected to central CO2 supply)
2. check co2 tank gasket is secured (need a wrench, spare gasket)
3. check that spare co2 tank is available in the OR
troubleshooting steps: image - CORRECT ANSWER-1. check that the monitor is
plugged in and turned on
2. check that all cables are connected correctly and securely
troubleshooting steps: view of operative field is reduced in size - CORRECT
ANSWER-immediately check the insufflator control panel to determine cause
troubleshooting steps: loss of working space: insufflator settings:
-measured pressure is the same or higher than the preset pressure
flow rate = 0 - CORRECT ANSWER-1. the patient may not be adequately relaxed
or there is a mechanical block of gas flow
, 2. inspect abdomen for rhythmic muscle contraction and palpate the abdomen for
firmness
3. check port valves to make sure they are open
4. check for kinks in tubing and make sure no one is standing on them
troubleshooting steps: loss of working space: insufflator settings:
-low pressure and high flow rate
flow rate = high - CORRECT ANSWER-1. there is a leak in the insufflation
circuit
2. check that the tubing has not become disconnected from insufflator or port
3. check that all valves are closed
4. check all port sites for leaking co2
5. check for foley catheter bag distention or bowel distention
troubleshooting steps: loss of working space: insufflator settings:
-low pressure and no flow
