ELECTROLYSIS IBEC & LASER STATE
BOARD TEST EXAM - ADVANCED
LEVEL QUESTIONS AND CORRECT
ANSWERS.
1. Which unit is used to measure the quantity of lye produced in the follicle during a Galvanic
treatment?
A. Watts
B. Faradays
C. Joules
D. Milliampere-seconds
Answer: D
Conceptual Explanation: In Galvanic electrolysis, the amount of sodium hydroxide (lye)
produced is calculated by multiplying the intensity (milliamperes) by the time (seconds).
2. What is the primary chromophore for hair removal lasers targeting the hair follicle?
A. Hemoglobin
B. Melanin
C. Water
D. Oxyhemoglobin
,Answer: B
Conceptual Explanation: Melanin is the target chromophore in laser hair removal, which
absorbs light energy to destroy the follicle via selective photothermolysis.
3. According to the principle of Selective Photothermolysis, the pulse duration should be:
A. Longer than the thermal relaxation time (TRT)
B. Exactly double the thermal relaxation time (TRT)
C. Shorter than or equal to the thermal relaxation time (TRT)
D. Irrelevant to the thermal relaxation time (TRT)
Answer: C
Conceptual Explanation: To prevent collateral damage, the laser pulse must deliver
energy within a timeframe shorter than or equal to the time it takes for the target to lose
50% of its heat.
4. Which endocrine disorder is characterized by an overproduction of cortisol by the adrenal
glands?
A. Addison’s Disease
B. Graves’ Disease
C. Cushing’s Syndrome
D. Hashimoto’s Thyroiditis
Answer: C
, Conceptual Explanation: Cushing’s Syndrome involves excess cortisol, which can lead to
hirsutism and other systemic symptoms.
5. High-frequency current used in thermolysis primarily creates heat through which
mechanism?
A. Chemical decomposition
B. Ionic bombardment
C. Direct electron transfer
D. Oscillation of molecules/Friction
Answer: D
Conceptual Explanation: Thermolysis uses high-frequency alternating current to vibrate
water molecules in the tissue, creating heat through friction.
6. The wavelength of an Alexandrite laser is:
A. 755 nm
B. 694 nm
C. 810 nm
D. 1064 nm
Answer: A
Conceptual Explanation: The Alexandrite laser operates at 755 nm, making it highly
effective for Fitzpatrick skin types I-III due to its high melanin absorption.
