Which condition can lead to bipolar hazards due to improper functioning of the device?

• A. Metal within the jaws
• B. Excessive irrigation
• C. Using a non-metal clip
• D. Operating at low power

Answer: (A)

Bipolar energy works by delivering current between two electrode surfaces across tissue, with the instrument insulated so energy targets only the tissue between the jaw tips. If there is metal inside the jaws, that metal can conduct electricity in an unintended way, altering the current path, changing impedance, or causing arcing. This can heat tissue outside the intended area or burn nearby structures, creating a hazardous situation known as a bipolar hazard. The other options don’t create that problematic current pathway: excessive irrigation mainly affects visualization and cooling, not the electrical path; a non-metal clip doesn’t provide a conductive path for the bipolar current; and operating at low power reduces energy delivery, lowering risk rather than creating a hazard.
