IBEC ELECTROLYSIS AND LASER
STATE BOARD ADVANCED PRACTICE
EXAM QUESTIONS AND CORRECT
ANSWERS.
1. Which chemical is produced at the negative electrode (cathode) during galvanic
electrolysis?
A. Hydrochloric Acid
B. Sodium Hydroxide
C. Sodium Hypochlorite
D. Hydrogen Peroxide
Answer: B
Conceptual Explanation: In galvanic electrolysis, the chemical reaction at the cathode
produces sodium hydroxide (lye), which is the primary agent used to decompose the hair
papilla.
2. The ‘Point Effect’ in thermolysis refers to the concentration of high-frequency energy at
what part of the needle?
A. The tip
B. The insulated portion
,C. The shank
D. The handle
Answer: A
Conceptual Explanation: The point effect describes the phenomenon where the high-
frequency current density is greatest at the tip of the needle, allowing for targeted
destruction.
3. What is the primary chromophore for hair removal lasers?
A. Water
B. Melanin
C. Hemoglobin
D. Collagen
Answer: B
Conceptual Explanation: Selective photothermolysis targets melanin in the hair shaft and
follicle to generate heat and destroy the germinative cells.
4. Which laser wavelength is considered the ‘gold standard’ for treating Fitzpatrick Skin Types
IV through VI?
A. 755 nm (Alexandrite)
B. 1064 nm (Nd:YAG)
C. 810 nm (Diode)
, D. 532 nm (KTP)
D. 532 nm (KTP)
Answer: B
Conceptual Explanation: The 1064 nm Nd:YAG laser has a lower affinity for melanin,
making it safer for darker skin types by bypassing the epidermis to target the follicle.
5. What is the duration of a pulse in laser hair removal usually measured in?
A. Nanoseconds
B. Microseconds
C. Milliseconds
D. Seconds
Answer: C
Conceptual Explanation: Pulse duration for hair removal is typically in the millisecond
range to match the thermal relaxation time of the hair follicle.
6. In the Blend method, what is the purpose of the high-frequency current?
A. To produce lye
B. To coagulate the blood
C. To heat the lye and speed up the chemical reaction
D. To numb the surrounding tissue
