1. The primary target in laser hair removal is
a. Collagen
b. Melanin
c. Hemoglobin
d. Water
b. Melanin
Melanin absorbs laser energy, allowing selective photothermolysis to
destroy the hair follicle without damaging surrounding tissue.
2. Which type of current is used in thermolysis?
a. Direct current
b. Alternating current
c. Galvanic current
d. Low-frequency current
b. Alternating current
Thermolysis uses high-frequency alternating current to produce heat that
destroys the follicle.
,3. The blend method in electrolysis combines
a. Galvanic and flash thermolysis
b. Shortwave diathermy and RF
c. Direct and alternating currents
d. Laser and galvanic currents
c. Direct and alternating currents
The blend method uses direct current for chemical destruction and
alternating current for heat destruction of the follicle.
4. In laser physics, fluence is measured in
a. Watts
b. Joules/cm²
c. Nanometers
d. Hertz
b. Joules/cm²
Fluence refers to the energy delivered per unit area and determines the
effectiveness of the treatment.
5. Which Fitzpatrick skin type has the highest risk of post-inflammatory
hyperpigmentation from laser hair removal?
a. Type I
b. Type III
c. Type V
d. Type II
c. Type V
Darker skin types have more melanin, increasing the risk of pigmentation
changes after laser exposure.
, 6. The primary function of the anode in galvanic electrolysis is to
a. Produce lye
b. Produce hydrogen gas
c. Produce heat
d. Reduce tissue
a. Produce lye
At the anode, direct current causes chemical decomposition, producing
sodium hydroxide (lye) that destroys the follicle.
7. Which wavelength is commonly used in Nd:YAG lasers for hair removal?
a. 755 nm
b. 1064 nm
c. 532 nm
d. 694 nm
b. 1064 nm
The Nd:YAG laser operates at 1064 nm, penetrating deeply and being
safer for darker skin types.
8. Which factor most affects laser penetration depth?
a. Spot size
b. Pulse duration
c. Wavelength
d. Cooling method
a. Spot size
A larger spot size allows deeper penetration into the skin due to reduced
scattering.
