  1. Which laser classification poses the greatest risk of immediate skin and eye injury without the ability to blink away in time?

    Answer: Class 4

    Class 4 lasers are high-power devices capable of causing immediate skin burns and severe eye injury, including fire hazards.

  2. What does the acronym ANSI stand for in the context of laser safety standards?

    Answer: American National Standards Institute

    ANSI stands for American National Standards Institute, which publishes Z136 laser safety standards used in the U.S.

  3. Which federal agency is primarily responsible for regulating laser devices as medical equipment in the United States?

    Answer: FDA/CDRH

    The FDA's Center for Devices and Radiological Health (CDRH) regulates laser products, including medical and cosmetic laser devices.

  4. A patient is scheduled for laser hair removal and is taking a photosensitizing antibiotic. What is the MOST appropriate action?

    Answer: Postpone treatment until the medication course is complete

    Photosensitizing medications increase the risk of adverse reactions; treatment should be postponed until the course is complete and cleared by the prescribing physician.

  5. What is the purpose of the Nominal Hazard Zone (NHZ) in laser safety?

    Answer: The zone in which direct or reflected beams may cause injury

    The NHZ defines the space within which the level of direct, reflected, or scattered radiation exceeds the applicable MPE and where protective measures are required.

  6. Which type of fire extinguisher is recommended for use in a laser treatment facility due to the risk of electrical fires?

    Answer: Class C (dry chemical or CO2)

    Class C extinguishers are rated for electrical fires, which are the most likely type in facilities with laser equipment.

  7. When performing laser treatments near the periorbital area, which protective measure is MANDATORY for the patient?

    Answer: Wearing wavelength-specific intraocular or external eye shields

    Wavelength-specific eye shields (internal or external) are mandatory to protect the patient's eyes from laser radiation near the periorbital region.
