Which laser best targets red vascular lesions? - answer Pulsed Dye or CuBr Yellow
In which skin structure is the stratum corneum located? - answer Epidermis
Anodized laser instruments have reduced reflectivity because: - answer The dulled,
roughened surface that anodization creates.
How often does the Epidermis renew itself? - answer3-5 weeks
The optimum pulse time, relative to the trt (thermal relaxation time) of the hair follicle
and skin (the melanosomes in the melanocytes of the skin) for laser hair removal, is: -
answerLonger than the trt for skin, but shorter than the follicle
What color of non-laser light is most often used in Photodynamic therapy (PDT) for skin
treatments such as acne or actinic keratosis to activate the photosensitizer, as
compared to the cancer treatments which PDT has been historically used for? -
answerBlue light
What are Vellus hairs? - answerVery fine, peach fuzz type hair
Diode lasers can be found in many wavelength ranges, but the most common range for
medical systems is: - answer530-1500 nm
What laser presents a Corneal rather than a Retinal eye hazard? - answerHo:Yag laser
The difference in protection (attenuation) from an Optical Density (O.D.) of 3 compared
to 6 is a factor of - answer1000
Which laser presents a corneal burn hazard, but not a retinal one? - answerEr:Yag laser
used for fractional skin resurfacing
Which variable changes irradiance (power density) the quickest? - answerChanging the
spot size on tissue
Some of the aesthetic laser handpieces use sapphire (or similar crystal) plates to
contact the skin and fire the laser through. What is the purpose of the circulating fluid
that flows through/around some of these plates? - answerThe fluid cools the plate,
which in turn cools the skin during treatment.
, What are the requirements for wearing Laser Safety Eyewear for personnel entering the
laser room (LTCA) according to ANSI Z136.3? - answerThe glasses must be made
available, but need not be worn until actually within the Nominal Hazard Zone (NHZ)
At the end of a hair growth cycle, what happens to the hair shaft? - answerIt sheds (falls
out)
Which laser(s) are used for non-ablative laser skin rejuvenation? - answerCuBr or
Pulsed Dye Yellow lasers
Diode lasers from about 810 to 1400 nm.
Nd:Yag lasers
What would be the wavelength of a typical diode laser used for laser hair removal? -
answer810 nm
Which is true of the Apocrine glands? - answerExcrete pheromes, which add to sexual
attraction
When a patient is in the middle of a series of laser or IPL procedures, and experiences
unexpected harsh reactions that did not occur in earlier treatments with identical
parameters, the most likely reason may be: - answerRecent sun exposure
When treating very dark skin, which laser would be "safer" during ablative (full surface)
laser skin resurfacing? - answerEr:Yag
NO additional window coverings would be required in a treatment room for which laser?
- answerEr:Yag laser
Which laser would be best suited for laser hair removal on black skin? - answerNd:Yag
By what mechanism does Photobiomodulation (PBM) work? Otherwise called Low
Level Laser Therapy (LLLT). - answerOrganelles and cell membranes are
photostimulated to mediate healing and pain relief mechanisms, including initiation of
enzyme cascade effects to create chemical reactions that repair cells and restore
balance.
The wavelength and color band of the Nd:Yag laser is: - answer1,064 nm Near Infrared
Conventional laser hair removal has a very difficult time with this hair color. -
answerRed
When aesthetic laser procedures are performed solely by non-medical personnel, what
is the major risk? - answerThe non-medical operator may miss or misdiagnose a skin
condition that is detrimental to the patient if they are not screened first by the physician
