FLS Modules Exam Questions with
correct Answers
Name of laparoscopic rod-lens system - Correct Answers -Hopkins rod-lens system
Type of light source typically used - Correct Answers -300 Watt Xenon lamp
How to check for damage of the fiber optic light cable - Correct Answers -holding one
end up to light and other end up to eye and look to see black
dots
Troubleshooting: 2 causes of small operating field despite measured pressure same or
higher than set pressure (eg 15 mmHg) - Correct Answers -1. pt may not be sufficiently
relaxed or 2.
there is mechanical obstruction of insufflation system
How electrical frequency changes from the wall to the monopolar/bipolar after it goes
through the ESU? - Correct Answers -low frequency current from wall to high frequency
As tissue temp raised past ***C protein denaturation occurs. - Correct Answers -60C
Superficial eschar formation with minimal depth of necrosis = this term - Correct
Answers -fulguration
Which ESU mode is this: heat quickly so water converts to steam —> cell explodes ;
heat is dissipated in
steam with minimal lateral thermal damage but poor coagulation. - Correct Answers -cut
Which ESU mode is this: Rapid surface heating. Intermittent wave form present with
high voltage. - Correct Answers –coag
How to minimize tissue friction/damage when pulling needle back through same port in
extracorp knot tying - Correct Answers -use 2nd instrument as a "fulcrum" to keep the
suture exiting the tissue at a shallow angle
These mechanical approx tools are simple and helpful for small tubular structures; not
good for closing openings in hollow organs - Correct Answers -clips
, Device that applies 2-3 rows of staples on each side of knife blade and cut tissue
between rows - Correct Answers -linear stapler
General idea between choosing staple size for a linear stapler - Correct Answers -
smaller staples = more hemostasis, thinner
tissue, larger staples= thicker tissue
Typical staple size for vascular structures/ mesentery?
For GI tract?
For distal stomach/ unusually thick GI tract - Correct Answers -2-2.5mm (white)
3-3.5mm (blue)
4-4.5mm (green)
Ideal suture length for intracorp knot tying - Correct Answers -6in/ 15cm
Trocar size best suited for introducing a standard SH-type needle - Correct Answers -
10-12mm
This occurs when current follows path of least resistance through unintentional
pathways. - Correct Answers -current diversion
Bipolar tissue sealing devices can seal up to ***mm diameter vessels - Correct Answers
-7mm
Type of technology described: high frequency vibration using piezoelectric transducer -
Correct Answers -ultrasonic coagulation
How inadvertent tissue injury can occur with use of an ultrasonic coagulation instrument
- Correct Answers -outside of active (vibrating) blade is unprotected and can
inadvertently injure tissue that comes into contact with it during / immediately after use.
ASA Class *** can't tolerate pneumoperitoneum - Correct Answers -4-5
Potentially hazardous effect in which current is passed from an active electrode to a
metal object (eg another lap instrument - called a passive electode or capacitor) not in
contact with tissue. Then, when the passive electrode/ capacitor touches tissue, it can
discharge the stored current - Correct Answers -capacitative coupling
What type of procedure can be performed without using GA? - Correct Answers -Dx lap
may be performed using local anesthesia alone or with mild sedation.
