Which of the following is an unsafe practice while operating the K-Laser?

Using the laser over the thyroid gland is considered an unsafe practice because the thyroid is sensitive to laser energy, and exposure can potentially lead to thermal damage or disrupt normal thyroid function. The tissues in that area are delicate, and the use of Class IV lasers requires caution when operating in proximity to vital organs and endocrine structures.

The other practices listed are essential for safe operation. Wearing K-Laser specific eyewear protects both the operator and the patient from unintentional exposure to the laser's light, which can be harmful to the eyes. Operating in a grounded circuit is vital for preventing electrical hazards that could lead to injury or equipment damage. Disinfecting areas before use is a critical hygiene practice to prevent infection and ensure patient safety, further emphasizing the importance of maintaining a sterile environment during laser treatment.
