Electrolysis IBEC+Laser STATE BOARD Practice test 2023 Questions with Correct Answers|UPDATED 2024 !!! Laser stands for what? Light Amplification by Stimulated Emission of Radiation What is the distance measured in nanometers between two peaks or two troughs known as? Wavelength Light of only one color & one specific wavelength is known as? Monochromatic Refraction is also known as what? Transmission The process where by a newly created photon of light (generated through amplification) acquires energy equal to the photons that created it is known as? Stimulated Emission The states of equilibrium or middle state of light Metastable State Who theorized stimulated emission? Albert Einstein The part of the laser that contains the active medium is called? Resinator cavity What are the states of light in stimulated emission? Ground State Excited State Singlet State Metastable State Alexandrite laer is in the visible light spectrum at what wavelength? 755 nm The Nd:YAG laser falls in the invisible light spectrum with a wavelength of what? 1064 nm What type of wave is used in laser hair removal? Pulsed wave A chromophore is also know at what? Target The chromophore absorbs what? Energy Goggles worn by the patient and practitioner must be approved by which group? ANSI (American National Standard Institute) for Class 3B and Class 4 Lasers Each laser wavelength is what to its machine? Specific What are the parameters when doing laser hair removal? Wavelength Spot Size Fluence Pulse Width Pulsed lasers allow for selective heating of specific targets, this is also known as? Selective Photothermolysis The rate/amount of energy delivered within a given area is known as? Fluence An increase in fluence equals an increase in what? Heat. Resulting in more damage The length of time the light/energy is in contact with the target that is measured in milliseconds (ms): Pulse width/Pulse duration If the time of pulse duration is changed from milliseconds to nanoseconds the laser is what? Q Switched A Q switched laser is used for what? Tattoo removal Which skin types can tolerate an Alex laser? 1-4 Which skin types can tolerate a Nd:YAG laser? All skin types Which skin type should only have electrolysis and no laser? Type 1 If the pulse width is greater than the thermal relaxation time it results in? A burn If the pulse width is less than or equal to the thermal relaxation time it results in? Perfect hair removal Larger structures have __________ thermal relaxation times (TRT) Longer Smaller structures have _______ thermal relaxation times (TRT) Shorter What kind of pulse widths protect the epidermis, penetrate deeper and cool more slowly? Long Longer pulse widths are for what skin type? 4-6 What kind of pulse widths are more aggressive and heat up and cool down quickly? Short Shorter pulse widths are for what skin type? 1-3 What percentage of follicles are damaged with each laser treatment? 15% What is a long-term stable reduction of the growing hairs after a treatment regime? Laser Hair Removal (LHR) What does the FDA call laser hair removal? Permanent hair reduction What is the highest setting the skin can tolerate without damage called? Fluence Threshold What is the highest setting the patient can tolerate without the treatment becoming impossible called? Patient Threshold The amount of hair per one square centimeter is known as? Hair density The higher the hair density, the _______ the fluence? Lower What percentage of overlapping do you want when doing LHR? 30% Darker/tanned skin requires what kind of fluence? Lower What should you never use to clean a patient's skin prior to LHR? Alcohol Pulse duration is measured in what unit? milliseconds (ms) Spot size is measured in what unit? millimeters (mm) Repetition rate is measured in what unit? hertz (Hz) Who is the grandfather of laser and was the first person to use water to cool the skin during laser? Rox Anderson The formula for fluence is? Joules = J/cm2 What kind of lasers allow for selective heating of specific targets? Selective photothermolysis For deeper laser penetration what should the practitioner do to the laser? Change to a bigger spot size The primary reason for using cooling devices during laser hair removal is? Allows for higher and more effective fluences to be used while sparing the epidermis During the initial consultation, the patient should be informed that the process will take how long for laser hair removal?
