Post-inflammatory hyperpigmentation (PIH) after laser treatment is most common in which Fitzpatrick skin types?
Answer: Fitzpatrick Types IV, V, and VI
PIH is significantly more common in darker Fitzpatrick skin types (IV–VI) because higher baseline melanin content makes melanocytes more reactive to laser-induced inflammation.
Which of the following is a relative contraindication (not absolute) for laser treatment?
Answer: Pregnancy
Pregnancy is a relative contraindication because while risks are not fully established, treatment is generally deferred until after delivery; absolute contraindications carry known definitive risks.
How should a CLS manage a client who develops hypopigmentation (loss of skin color) following laser treatment?
Answer: Document the finding, reassure the client, and refer to a physician for evaluation
Hypopigmentation should be documented and the client referred to a physician for evaluation, as it may indicate permanent melanocyte damage requiring specialist management.
Which eye hazard is the primary safety concern when using Nd:YAG lasers near the periorbital area?
Answer: Retinal damage from penetrating 1064 nm radiation
Nd:YAG 1064 nm radiation is transmitted through the cornea and lens to reach the retina, where it can cause permanent retinal damage if proper eye protection is not used.
A client reports intense itching and urticaria (hives) that developed within minutes of beginning laser treatment. What should the CLS do first?
Answer: Stop treatment and assess for signs of allergic reaction or anaphylaxis
Rapid-onset urticaria can be a sign of systemic allergic reaction or anaphylaxis; treatment must stop immediately and the client must be assessed for emergency intervention.
What does the term 'frosting' indicate when observed during laser tattoo removal treatment?
Answer: Immediate whitening of the skin caused by rapid gas formation from ink fragmentation
Frosting is the immediate white discoloration seen during Q-switched laser tattoo removal, caused by rapid formation of CO2 gas bubbles from laser-ink interaction.
