FLS Exam Questions with Correct
Answers 100% PASS
What are the laparoscope diameters? - CORRECT ANSWER-2-10mm
Which degree scope is best for a field in line with port? - CORRECT ANSWER-0
degree
How to prevent fogging of scope? - CORRECT ANSWER-Use anti fog solution
or put scope in hot water/hot bath
What is the most commonly used light source? - CORRECT ANSWER-300 W
Xenon lamp
What if there is initial low pressure and high flow rate at entry? - CORRECT
ANSWER-Leak in insufflator circuit, make sure everything plugged in correctly
Benefits of monopolar - CORRECT ANSWER-Tissue is heated quickly, less
thermal damage/coagulation
Monopolar voltage/frequency - CORRECT ANSWER-Low voltage/High
frequency
,What does coagulation mode do? - CORRECT ANSWER-Repid surface heating
with shallow depth of necrosis, intermittent wave form with higher voltage
Risk of monopolar - CORRECT ANSWER-Current can be diverted through
unintentional pathways, leading to inadvertent tissue injury. Don't use hybrid ports
that mix metal with plastic
Why do you need a grounding pad for monopolar? - CORRECT ANSWER-
Capacitative coupling - transfer of energy between two conductors separated by an
insulator, transfer to passive electrode. Can release with tissue injury, but no issue
if ground plate is working as capacitor can't store the charge
Benefits of bipolar - CORRECT ANSWER-lower energy, producing less lateral
tissue damage and necrosis. Don't need a grounding pad
Risk of bipolar - CORRECT ANSWER-Risk of cutting patient vessels before
adequate sealing, and device doesn't work if there is metal between the jaws
Risk of ultrasonic dissection (harmonic) - CORRECT ANSWER-Active blade can
injure something due to high frequency (50mHz)
Discontinue aspirin day of surgery? - CORRECT ANSWER-No
How to enter in patient with bowel obstruction? - CORRECT ANSWER-Direct
visualization

,Cut vs Coag - CORRECT ANSWER-cut - heat tissue quickly to convert cell water
to steam, lysing the cell
Coag - heat more widely dispersed, less cutting action
smaller tissue area, greater current density and faster heating - CORRECT
ANSWER-e.g. Bovie tip
Cut mode - CORRECT ANSWER-- Low voltage
- High frequency
- Continuous waveform
- Heats tissue quickly; cell water converts to steam and causes cell to explode
Coagulation mode - CORRECT ANSWER-- High voltage
- Low frequency
- Intermittent waveform
- Rapid tissue heating, shallow depth of necrosis
- Non-contact: relies on sparking to tissue
Capacitive coupling - CORRECT ANSWER-Transfer current from active
electrode through insulation to passive electrode- electrode to plastic part another
LSC instrument
- if constant contact w/ tissue will not store energy and no injury
, Direct coupling - CORRECT ANSWER-monopolar instrument in direct contact
w/ metal portion of another instrument
Besides capacitative coupling and direct coupling, other hazards of electrocautery -
CORRECT ANSWER-- Current diversion
- Narrow return circuit
Bipolar - CORRECT ANSWER-- forceps w/ two twins (one active other return)
- no pt return electrode required)
- no capacitative coupling
- works in "wet" operative field
- less thermal spread compared to monopolar
bipolar seals vessels up to _____ mm in diameter - CORRECT ANSWER-7 mm
ultrasonic coagulation shears seals vessels up to ____ mm in diameter -
CORRECT ANSWER-5 mm
ultrasonic coagulation shears - CORRECT ANSWER-- combo compression and
friction
- ONE active blade
- monopolar capacity w/ the one blade
