GUARANTEED PASS | LATEST UPDATE
This comprehensive study guide contains 200 unique, multiple-choice questions with correct
answers and detailed rationales, specifically designed for the IBEC Electrology and Laser State
Board Examination. Each question targets a distinct topic from the official exam domains,
including laser physics, selective photothermolysis, hair growth cycles, electrolysis modalities
(galvanic, thermolysis, blend), skin anatomy, patient safety, contraindications, infection control,
sterilization protocols, FDA classifications, Fitzpatrick skin typing, treatment parameters, and
complication management. The questions are presented in a clear ABCD format without
repetitive content, ensuring thorough coverage of all essential concepts needed for board
certification and state licensure in electrology and laser hair removal.
1. What does LASER stand for?
A) Light Amplification by Stimulated Emission of Radiation
B) Light Absorption by Stimulated Energy Reaction
C) Laser Amplification by Synchronized Emission of Radiation
D) Light Amplification by Synchronized Energy Response
Correct Answer: A
Rationale: LASER is an acronym that describes the process by which laser light is
produced. The key principle is "stimulated emission," where photons are emitted
when atoms are excited and return to a lower energy state .
2. What is the wavelength of the Alexandrite laser?
A) 694 nm
1
,B) 755 nm
C) 800 nm
D) 1064 nm
Correct Answer: B
Rationale: The Alexandrite laser operates at a wavelength of 755nm, which is in
the visible red light spectrum. It is effective for hair removal on Fitzpatrick skin
types I-IV .
3. What is the wavelength of the Nd:YAG laser?
A) 755 nm
B) 800 nm
C) 810 nm
D) 1064 nm
Correct Answer: D
Rationale: The Nd:YAG laser operates at 1064nm, in the invisible infrared
spectrum. This longer wavelength allows for deeper skin penetration and makes it
safe for use on all skin types, including darker skin .
4. Light of only one color and one specific wavelength is known as?
A) Coherent
B) Collimated
C) Monochromatic
D) Polychromatic
Correct Answer: C
Rationale: Monochromaticity means the laser emits light at one specific
wavelength, allowing precise targeting of chromophores. Traditional light beams
are polychromatic, consisting of many colors or wavelengths .
2
,5. What type of wave is used in laser hair removal?
A) Continuous wave
B) Pulsed wave
C) Modulated wave
D) Static wave
Correct Answer: B
Rationale: Pulsed lasers allow for selective heating of specific targets by delivering
energy in short bursts. This is a critical aspect of selective photothermolysis, which
spares surrounding tissue .
6. Pulsed lasers allow for selective heating of specific targets; this is also known
as?
A) Thermal Relaxation
B) Photochemical Effect
C) Selective Photothermolysis
D) Photoablation
Correct Answer: C
Rationale: Selective photothermolysis is the principle that allows for the
destruction of a target (chromophore) using a specific wavelength and pulse
duration, minimizing damage to surrounding tissue .
7. A chromophore is also known as what?
A) A type of laser
B) The target
C) A cooling device
D) An electrical current
3
, Correct Answer: B
Rationale: A chromophore is the target structure that absorbs the laser light. In hair
removal, the primary chromophore is melanin in the hair shaft and bulb .
8. Goggles worn by the patient and practitioner must be approved by which group?
A) FDA
B) OSHA
C) ANSI
D) CDC
Correct Answer: C
Rationale: Laser safety eyewear must be approved by the American National
Standards Institute (ANSI), specifically for Class 3B and Class 4 lasers, to ensure
adequate optical density for protection .
9. What are the parameters when doing laser hair removal?
A) Wavelength, Spot Size, Fluence, Pulse Width
B) Wavelength, Intensity, Duration, Cooling
C) Spot Size, Temperature, Repetition Rate, Cooling
D) Fluence, Joules, Hertz, Nanometers
Correct Answer: A
Rationale: The four key parameters for laser hair removal are wavelength
(determines target), spot size (affects penetration depth), fluence (energy dose),
and pulse width (duration of energy delivery) .
10. The amount of hair per one square centimeter is known as?
A) Hair thickness
B) Hair density
