FLS WRITTEN EXAM 2025
ANSWER ALL QUESTIONS IN THIS SECTION
QUESTION 1
what is the most commonly used light source? - ANSWERS-300 W xenon lamp
QUESTION 2
what if there is initial low pressure and high flow rate at entry? - ANSWERS-leak
in insufflator circuit, make sure everything is plugged in correctly
QUESTION 3
what does coagulation mode do? - ANSWERS-rapid surface heating with shallow
depth of necrosis, intermittent wave form with higher voltage
QUESTION 4
risks of monopolar - ANSWERS-current can be diverted through unintentional
pathways, leading to inadvertent tissue injury
- don't use hybrid ports that mix metal with plastic

QUESTION 5
why do you need a grounding pad for monopolar? - ANSWERS-capacitative
coupling - transfer of energy between two conductors separated by insulator,
transfer to passive electrode. can release with tissue injury but no issue if ground
plate working as capacitor - can't store the charge
QUESTION 6
benefits of bipolar energy - ANSWERS-lower energy, producing less lateral tissue
damage and necrosis
- DONT need a grounding pad
QUESTION 7
risks of bipolar energy - ANSWERS-risk of cutting patient vessels before adequate
sealing, device doesn't work if metal between the jars
QUESTION 8
risks of ultrasonic dissection (harmonic) - ANSWERS-active blade can injure
something due to high frequency (50 MHz)
