CLT Laser Safety & Protocols 3

Question 1

Which chromophore is the primary target when using a 1064 nm Nd:YAG laser for vascular lesion treatment?

Accepted Answer

Oxyhemoglobin

Answer

Oxyhemoglobin has an absorption peak near 1064 nm, making Nd:YAG effective for deeper vascular lesions.

Question 2

What is the correct response if a client experiences immediate urticarial reaction (hives) during a laser session?

Accepted Answer

Stop treatment immediately, assess for anaphylaxis, and follow emergency protocol

Answer

Urticaria can be an early sign of an allergic or anaphylactic reaction; treatment must stop immediately and emergency protocols must be followed.

Question 3

What term describes the technique of delivering laser energy in multiple rapid pulses to limit thermal diffusion to surrounding tissue?

Accepted Answer

Selective photothermolysis

Answer

Selective photothermolysis uses pulses shorter than the thermal relaxation time of the target to confine heat damage to the chromophore without harming surrounding tissue.

Question 4

Which personal protective equipment (PPE) is mandatory for both the operator AND the client during all laser procedures?

Accepted Answer

Wavelength-specific optical density-rated eyewear

Answer

Wavelength-specific laser safety eyewear with adequate optical density is required for all individuals in the treatment room to prevent ocular injury.

Question 5

A laser technician notices the treatment room door was left open during a procedure. What is the immediate priority?

Accepted Answer

Stop firing, secure the room, and ensure no unauthorized personnel were exposed

Answer

An open door during laser use exposes unauthorized personnel to beam hazards; firing must stop immediately and the area must be secured.
