FES EXAM SCRIPT TESTED QUESTIONS AND
SOLUTIONS CERTIFICATION EVALUATION
●● What are the two ways endoscopes transmit a digital image?
Answer: 1) Charge-coupled device (CCD)
2) Complementary metal-oxide semiconductors (CMOS)
●● Location of the suction/biopsy channel (clock face)
Answer: Between 5 and 7 o'clock
●● What 6 things are typically found on an endoscopy cart?
Answer: 1) monitor
2) video processor
3) light source with insufflator
4) water bottle
5) CO2 source
6) connection to image management and reporting systems
●● Umbilical cable (purpose)
Answer: Connects the endoscope and the light
source/suction/water/insufflation/video processing unit
,●● What irrigation fluid should be used? Why?
Answer: Water. Saline will cause a build up of salt crystals in the
channel.
●● What should be tested prior to starting an endoscopy
Answer: 1) produces bubbles
2) squirts water
3) sucks water
3) light is on
4) tip moves in all directions
●● Trouble shoot the problem: no light
Answer: 1) Light sourced plugged in and turned on
2) Light not on standby mode
3) Lens at distal tip isn't dirty
4) The bulb isn't burned out
●● Trouble shoot the problem: out of focus
Answer: 1) clean lens
2) white balance
●● Trouble shoot the problem: no irrigation
,Answer: 1) bottle contains water
2) water bottle connected to umbilical cord
3) lid of water bottle is secure
4) power is turned on
5) the valve isn't stuck or occluded
●● Trouble shoot the problem: no insufflation
Answer: 1) umbilical cord firmly seated into light source
2) power is turned on
3) the valve is stuck or occluded
●● Trouble shoot the problem: clogged valve or nozzle
Answer: 1) take valve apart and clean
2) flush channel of endoscope with cleaning solution then water
●● Trouble shoot the problem: unable to pass instrument in channel
Answer: 1) confirm size of the instrument and working channel
2) ensure the instrument is closed
3) decrease the tip deflection
●● What is the channel that is associated with the suction button
Answer: The biopsy channel
, ●● If the scope doesn't have a dedicated auxiliary channel, what can be
used for irrigation?
Answer: The suction/biopsy channel
●● Informed consent is based on what 2 principles
Answer: 1) autonomy
2) self-determination
●● NPO guidelines- clear liquids
Answer: 2 hrs
●● NPO guidelines- breast milk
Answer: 4 hrs
●● NPO guidelines- infant formula/non-human milk
Answer: 6 hrs
●● NPO guidelines- light meal
Answer: 6 hrs
●● NPO guidelines- fatty foods or meat
