FLS Module 1 Exam Questions with
Answers 100% PASS
What are available laparoscope diameters? - CORRECT ANSWER-2-10mm
What degree scope is best for a field of view in-line with a port? - CORRECT
ANSWER-Zero degree
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-There may be a leak in the insufflator circuit. Check all connections.
Benefits of Monopolar energy. - CORRECT ANSWER-Tissue heated quickly.
Less thermal spread/coagulation.
Monopolar voltage/frequency - CORRECT ANSWER-Low voltage, High
frequency
What does coagulation mode do? - CORRECT ANSWER-Rapid surface heating
with shallow depth of necrosis. intermittent wave form with higher voltage.
,What are some risks of monopolar energy? - CORRECT ANSWER-Current can
be diverted through unintentional pathways leading to inadvertent tissue injury. To
avoid this, do not use "hybrid" ports that mix plastic with metal.
How does a grounding pad avoid injury with monopolar energy? - CORRECT
ANSWER-Grounding pads help avoid capacitative coupling. This happens when
two conductors are separated by an insulator and the passive electrode stores
energy that can be released with tissue injury. The grounding pad inhibits the
passive electrode from storing energy.
Benefits of bipolar energy. - CORRECT ANSWER-- Lower risk of inadvertent
injury.
- Produces less thermal spread and necrosis.
- No grounding pad necessary.
- Works in a "wet" operative field.
Risks of bipolar energy. - CORRECT ANSWER-May cut patent blood vessels
before adequate sealing. Device will not work if there is metal between the jaws.
Risk of ultrasonic dissection (harmonic). - CORRECT ANSWER-The active blade
can inadvertently injure something due to high frequency (50mHz).
Does aspirin need to be discontinued day of surgery. - CORRECT ANSWER-No

, How to best enter a patient with bowel obstruction. - CORRECT ANSWER-
Direct visualization.
Cut vs Coag - CORRECT ANSWER-Cut: Heats tissue quickly to convert cell
water to steam, lysing the cell.
Coag - Heat more widely dispersed, less cutting.
Benefits of "Cut mode" - CORRECT ANSWER-- Low voltage
- High frequency
- Continuous waveform
- Heats tissue quickly. Cell water converts to steam and causes the cell to
lyse/explode.
Benefits of "Coagulation mode" - CORRECT ANSWER-- High voltage
- Low frequency
- Intermittent waveform
- Rapid tissue heating, shallow depth of necrosis.
- Non-contact. Relies on sparking to tissue.
What is direct coupling? - CORRECT ANSWER-When a monopolar instrument is
in direct contact with another metal instrument and energy is transferred.
What are other dangers of energy use besides direct and capacitative coupling? -
CORRECT ANSWER-- Current diversion
