CLT Client Assessment & Treatment Planning 2

Question 1

A client with Fitzpatrick Skin Type V presents for laser hair removal. Which laser wavelength is MOST appropriate to minimize the risk of post-inflammatory hyperpigmentation?

Accepted Answer

1064 nm Nd:YAG

Answer

The 1064 nm Nd:YAG laser is preferred for darker Fitzpatrick skin types (IV-VI) because its longer wavelength penetrates deeper with less melanin absorption in the epidermis, reducing the risk of PIH.

Question 2

During a client intake, a client discloses they take isotretinoin (Accutane). What is the recommended waiting period after stopping the medication before performing laser treatments?

Accepted Answer

6 months

Answer

Most clinical guidelines recommend waiting at least 6 months after discontinuing isotretinoin before laser treatments due to increased photosensitivity and impaired wound healing.

Question 3

Which clinical finding during skin assessment would be considered an absolute contraindication for laser hair removal on the treatment area?

Accepted Answer

Active herpes simplex lesion in the area

Answer

An active herpes simplex lesion is an absolute contraindication because laser energy can spread the virus, causing widespread infection.

Question 4

A client reports using a self-tanning product two weeks ago. What is the BEST course of action before proceeding with laser treatment?

Accepted Answer

Postpone treatment until tan fades completely

Answer

Self-tanning products deposit dihydroxyacetone in the epidermis, temporarily darkening the skin and increasing the risk of burns; treatment should be postponed until the tan fully fades.

Question 5

When reviewing a client's medical history for laser treatments, which medication class poses the greatest risk for photosensitivity reactions?

Accepted Answer

Tetracycline antibiotics

Answer

Tetracycline antibiotics (and other photosensitizing drugs like fluoroquinolones and some diuretics) can cause exaggerated skin reactions when exposed to laser energy.
