TATTOO REMOVAL EXAM QUESTIONS
AND ANSWERS
4 purposes of cooling - ANSWER-to provide a numbing effect, reduces patients
discomfort, reduces and diffuses the heat from the surface of the epidermis, reduces
erythema, reduces bruising, reduces edema
punctate bleeding - ANSWER-small pinpoints of blood on the surface of the skin
melanocytes - ANSWER-cells that produce melanin, the pigment that gives the skin its
colour and helps protect the dermis
tanning - ANSWER-the body's built in biological defense system to shield itself from the
damaging effects of exposure to the suns ultra violet rays
difference between nanosecond and picosecond technology - ANSWER-QS laser
nanosecond: pulse duration in a billionth of a second, it has a photothermal effect and
partially photoacoustic or photomechanical effect
QS laser picosecond: pulse duration in a trillionth of a second, it has photoacoustic
effect or photomechanical, breaks down the ink in very small pieces → less treatments
required
what is paradoxical darkening and which colors are involved - ANSWER-irreversible
hyperpigmentation after laser tattoo due to the oxidation of the ferric oxide containing in
the ink → converted into ferrous oxide → pigmentation
tattoo ink colors: white, pink, tan, red, peach or flesh color
what does Q switch stand for? - ANSWER-quality switch
quality switch - ANSWER-q switched laser emits short and very high power pulses
people with which skin type is most likely to experience side effects from laser and light
treatments? - ANSWER-Fitzpatrick types IV to VI
6 contraindications of tattoo removal - ANSWER-pregnancy, heart conditions,
haemophilia, herpes simplex virus, keloid scarring, metal plates
what size spot sizes slightly increase the effective penetration depth of a laser? -
ANSWER-larger spot sizes
larger spot size allows for? - ANSWER-deeper penetration of laser
, higher repetition rates can allow what? - ANSWER-higher repetition rates can allow you
to cover larger areas extremely quickly, but more care is needed to avoid overlapping
pulsing and consequent damage
average amount of treatments for tattoo removal - ANSWER-average is 5, but some
tattoos require 12 or more treatments
how long in between tattoo removal can treatments be given? - ANSWER-8 weeks
what is post inflammatory hyperpigmentation - ANSWER-hyperpigmentation is the over
production of melanin pigment in the skin, the skin will show post inflammatory
hyperpigmentation as part of the natural healing process of a wound
people with higher Fitzpatrick are most likely to experience side effects from laser and
light treatments. true or false - ANSWER-true
difference between nanosecond and picosecond technology - ANSWER-nanosecond →
billionth of a second, photothermal effect, break down ink in pebbles
picosecond → trillionth of a second, photoacoustic effect, break down ink in sand
what laser to use regarding the patient's tattoo color - ANSWER-S 1064 NdYag →
black, dark blue, dark brown ink
QS Alexandrite 755 → green, blue ink
QS 532nm NdYag → red, orange, light brown, violet ink
QS Rubi 694nm→ turquoise, light blue, light green ink
types of tattoos - ANSWER-professional, amateur, cosmetic, medical, traumatic
_______ spot sizes slightly increase the effective penetration depth of the laser -
ANSWER-larger
________ repetition rates can allow you to cover larger areas quickly, but more care is
needed to avoid overlapping pulsing and consequent damage - ANSWER-higher
repetition rates
how long to wait after taking accutane - ANSWER-6 months
how do you take care of your skin after a laser treatment - ANSWER-cold gel packs to
reduce redness and swelling and relieve discomfort. apply antibiotic ointment ad gauze
bandage to treated area for a few days up to 2 weeks, until all lesions are healed
what is developed after pulsing a laser over tattoos that contain iron, ferrous oxide. the
ink oxides causing permanent hyperpigmentation - ANSWER-paradoxical darkening
what is a macrophage - ANSWER-white blood cell, in charge of eliminating foreign
materials from your body
