CLT Client Assessment & Treatment Planning 3 — Questions and Answers
Question 1: A client presents for IPL treatment but mentions they had a chemical peel 10 days ago. What should the technician do?
- Proceed with lower fluence
- Postpone treatment until skin fully heals (typically 4–6 weeks) (Correct answer)
- Apply a barrier cream and proceed
- Use the highest wavelength filter available
Correct answer: Postpone treatment until skin fully heals (typically 4–6 weeks)
Recent chemical peels compromise the skin barrier and increase photosensitivity; waiting 4–6 weeks ensures the skin has fully recovered before laser or IPL treatment.
Question 2: In developing a laser treatment plan for photorejuvenation, which factor should be assessed to determine appropriate pulse duration?
- Client's hair texture
- Thermal relaxation time of the target chromophore (Correct answer)
- Ambient room temperature
- Number of previous laser sessions
Correct answer: Thermal relaxation time of the target chromophore
Pulse duration should be at or below the thermal relaxation time (TRT) of the target chromophore to ensure selective photothermolysis without damaging surrounding tissue.
Question 3: A client with a history of keloid scarring requests laser resurfacing. What is the most appropriate action?
- Proceed with standard settings
- Perform a patch test and obtain physician clearance before treating (Correct answer)
- Double the post-treatment cooling time
- Use a higher fluence to ensure efficacy
Correct answer: Perform a patch test and obtain physician clearance before treating
Keloid history is a relative contraindication for ablative laser procedures; physician clearance and a patch test are required to assess individual risk before proceeding.
Question 4: Which question is MOST critical to include in a pre-treatment consultation for laser vein treatment?
- What is your favorite skincare brand?
- Have you been diagnosed with a blood clotting disorder? (Correct answer)
- Do you exercise regularly?
- Have you had any dental work in the last year?
Correct answer: Have you been diagnosed with a blood clotting disorder?
Blood clotting disorders can increase bleeding risk and affect vascular response to laser energy, making this a critical safety question before vein treatments.
Question 5: What is the purpose of performing a test spot (patch test) before a full laser treatment?
- To determine the client's pain tolerance only
- To assess individual skin response, calibrate settings, and identify adverse reactions (Correct answer)
- To satisfy insurance requirements
- To warm up the laser device before full use
Correct answer: To assess individual skin response, calibrate settings, and identify adverse reactions
A patch test evaluates the skin's reaction to specific laser settings, allowing the technician to optimize parameters and detect unexpected responses before full treatment.
Question 6: A client's informed consent form should include all of the following EXCEPT:
- Expected results and number of sessions
- Potential risks and side effects
- Technician's personal home address (Correct answer)
- Alternative treatment options
Correct answer: Technician's personal home address
Informed consent must include realistic outcomes, risks, and alternatives, but never includes personal information about the provider such as a home address.
Question 7: When assessing hair color before laser hair removal, which characteristic makes treatment LEAST effective?
- Dark brown hair
- Coarse black hair
- Light blonde or white hair (Correct answer)
- Red hair on pale skin
Correct answer: Light blonde or white hair
Light blonde or white hair lacks sufficient melanin to absorb laser energy, making laser hair removal largely ineffective for these hair colors.
