What safety considerations apply to placing electrodes near the head and neck?

• A. Place electrodes directly over the eyes for best stimulation
• B. Always place electrodes on the forehead for best grounding
• C. Use maximum intensity near skull for penetration
• D. Avoid direct over the eyes and carotid sinus; avoid high intensities near the skull; ensure patient comfort and monitor closely; do not place over implanted devices in sensitive regions

Answer: (D)

Safety when placing electrodes near the head and neck focuses on protecting vulnerable structures and preventing adverse effects. Don’t place electrodes directly over the eyes because electrical stimulation can damage ocular tissues or cause uncomfortable visual sensations. Avoid stimulating near the carotid sinus to prevent triggering reflex changes in heart rate or blood pressure. Using high intensities near the skull raises the risk of skull heating, skin burns, and unintended brain stimulation. Always prioritize patient comfort, monitor the response during treatment, and avoid electrode placement over implanted devices in sensitive regions to prevent interference or heating. This combination of precautions best captures safe practice in cranial/neck electrode placement.
