Question 1

Picosecond lasers differ from Q-switched nanosecond lasers in tattoo removal primarily because they:

Accepted Answer

Deliver energy in shorter pulses for a greater photomechanical effect

Answer

Picosecond lasers fire in trillionths-of-a-second pulses, creating a more efficient photomechanical shockwave that shatters ink into finer particles with potentially fewer sessions and less collateral thermal damage.

Question 2

Which of the following is an ABSOLUTE contraindication for laser tattoo removal?

Accepted Answer

Active bacterial skin infection overlying the tattooed area

Answer

An active infection in the treatment zone is a contraindication because laser energy would disrupt the skin barrier, risk spreading pathogens, and impair healing.

Question 3

The clinical endpoint indicating adequate treatment during a tattoo removal session is:

Accepted Answer

Immediate whitening (frosting) of the treated area

Answer

Immediate whitening or frosting of the treated area indicates that sufficient energy was delivered to cause the photomechanical effect within the dermis and is the standard treatment endpoint.

Question 4

Which aftercare instruction is MOST important immediately following laser tattoo removal?

Accepted Answer

Apply antibiotic ointment and keep the area clean and moist

Answer

Applying antibiotic ointment and keeping the treated area moist promotes optimal wound healing, prevents infection, and minimizes the risk of scarring.

Question 5

In the context of laser tattoo removal, 'selective photothermolysis' means:

Accepted Answer

The laser selectively destroys tattoo ink while minimizing damage to surrounding tissue

Answer

Selective photothermolysis means the chosen wavelength is preferentially absorbed by tattoo ink (the target chromophore) while largely sparing adjacent tissue, reducing collateral damage.
