CLT Vascular & Pigmented Lesion Treatment 4

Question 1

A laser technician is treating a patient's rosacea-associated erythema. The ideal endpoint for facial diffuse redness is:

Accepted Answer

Transient mild erythema and edema without purpura

Answer

For diffuse erythema treatment, the goal is sub-purpuric dosing that produces mild erythema and edema without vessel rupture, reducing downtime.

Question 2

IPL (intense pulsed light) differs from laser in that it:

Accepted Answer

Emits a broad spectrum of light filtered to target ranges

Answer

IPL emits polychromatic light across a broad spectrum (typically 500–1200 nm) and uses cut-off filters to select wavelength ranges appropriate for specific chromophores.

Question 3

Which post-treatment instruction is most critical after laser treatment of pigmented lesions?

Accepted Answer

Use broad-spectrum SPF 30+ sunscreen and minimize UV exposure

Answer

Sun avoidance and SPF 30+ sunscreen use are essential post-treatment to prevent UV-triggered PIH and protect newly treated skin.

Question 4

Which of the following best describes a cherry angioma and its typical laser treatment response?

Accepted Answer

A benign capillary proliferation that responds well to KTP or PDL

Answer

Cherry angiomas are benign capillary lesions that respond excellently to KTP (532 nm) or pulsed dye laser targeting oxyhemoglobin.

Question 5

Test spots are most important when treating which patient scenario?

Accepted Answer

A darker-skinned patient with multiple lentigines being treated for the first time

Answer

Test spots are critical for new patients with higher Fitzpatrick skin types or multiple pigmented lesions to assess chromophore response and minimize adverse effects.
