Multiple Choice Questions ________________________________________ SECTION 1: LASER FUNDAMENTALS (Questions 1-50) 1. What does LASER stand for? A) Light Amplification by Stimulated Emission of Radiation B) Light Absorption by Stimulated Emission of Radiation C) Laser Amplification by Systematic Emission of Radiation D) Light Amplification by Systematic Emission of Radiation Answer: A Rationale: LASER is an acronym for Light Amplification by Stimulated Emission of Radiation, which describes the process by which laser light is produced. ________________________________________ 2. What is the name of the scale that measures all known wavelengths? A) Visible Light Spectrum B) Electromagnetic Spectrum C) Wavelength Scale D) Radiation Spectrum Answer: B Rationale: The electromagnetic spectrum encompasses all known wavelengths of electromagnetic radiation, from gamma rays to radio waves. ________________________________________ 3. What determines the depth penetration of laser energy? A) Fluence and pulse width B) Wavelength and spot size C) Power and energy D) Pulse duration and frequency Answer: B Rationale: Wavelength determines how deeply light penetrates tissue, and spot size affects the distribution of energy. Together they determine depth penetration. ________________________________________ 4. Which of the following is NOT one of the four basic parameters of laser? A) Wavelength B) Spot size C) Fluence D) Frequency Answer: D Rationale: The four basic parameters of laser are wavelength, spot size, fluence, and pulse width. Frequency is not one of the basic parameters. ________________________________________ 5. How is wavelength measured? A) Millimeters, trough to trough B) Nanometers, peak to peak C) Micrometers, peak to trough D) Centimeters, trough to peak Answer: B Rationale: Wavelength is measured in nanometers (nm) from peak to peak of the wave. ________________________________________ 6. Thermal relaxation time (TRT) is the time necessary for target tissue to cool down by what percentage? A) From 100% of the heat to 75% cooler B) From 100% of the heat to 50% cooler C) From 100% of the heat to 25% cooler D) From 100% of the heat to 90% cooler Answer: B Rationale: TRT is defined as the time required for the target tissue to cool from 100% of the heat to 50% cooler. ________________________________________ 7. Which of the following is NOT a type of epidermal cooling? A) Chilled or cooling gel B) Contact cooling including sapphire tip C) Cryogen spray D) Ice pack compression Answer: D Rationale: The four types of epidermal cooling are chilled/cooling gel, contact cooling (sapphire tip), cryogen spray, and air cooling. Ice pack compression is not listed as a primary method. ________________________________________ 8. What is selective Photothermolysis? A) Destroying all tissue in the treatment area equally B) Adequately destroying a chromophore without damaging surrounding tissue C) Heating the entire skin surface uniformly D) Using multiple wavelengths simultaneously Answer: B Rationale: Selective Photothermolysis is the principle of targeting specific chromophores (targets) with laser energy while sparing surrounding tissue from damage. ________________________________________ 9. Eye protection is needed while using which classification of lasers? A) Class 1 and 2 B) Class 2 and 3a C) Class 3b and 4 D) All classes Answer: C Rationale: Eye protection is required for Class 3b and Class 4 lasers, which are considered hazardous to the eyes. ________________________________________ 10. What type of eyewear should the client wear during laser treatment? A) Standard sunglasses B) Same laser goggles as technician C) Prescription glasses D) No eye protection needed Answer: B Rationale: Clients should wear the same type of laser goggles as the technician, with appropriate wavelength protection specific to the laser being used. ________________________________________ 11. What is optical density? A) The brightness of laser light B) The amount of attenuation or reduction of radiant laser energy as it passes through the filter material C) The distance light travels D) The power output of the laser Answer: B Rationale: Optical density refers to the amount of attenuation (resistance filter) or reduction of radiant laser energy as it passes through the filter material in laser eyewear. ________________________________________ 12. Where should fire extinguishers be located? A) In the hallway only B) In the treatment room C) At the front desk D) Outside the building Answer: B Rationale: Fire extinguishers should be located in the treatment room for immediate access in case of fire emergency. ________________________________________ 13. How long should a client avoid the sun for a laser cosmetic and aesthetic treatment? A) 2 weeks B) 3 weeks C) 4 weeks D) 6 weeks Answer: C Rationale: Clients should avoid sun exposure for 4 weeks before laser cosmetic and aesthetic treatments. ________________________________________ 14. How long should a client avoid sun before laser hair removal? A) 1-2 weeks B) 2-4 weeks C) 4-6 weeks D) 6-8 weeks Answer: B Rationale: Clients should avoid sun exposure for 2-4 weeks before laser hair removal treatments. ________________________________________ 15. Tetracycline is an oral antibiotic used to treat what? A) Fungal infections B) Acne C) Viral infections D) Bacterial infections of the skin only Answer: B Rationale: Tetracycline is an oral antibiotic commonly used to treat acne. It is bacteriostatic, meaning it prevents bacteria from multiplying.
