Which practice helps reduce ignition risk when using electrosurgery?

Answer

The correct practice to reduce ignition risk is to holster the electrosurgical electrode (or pencil) in a non-conductive, safety holster when it is not actively being used. Leaving the active tip on the patient, activating the pencil anytime, or using rubber sleeves over active electrodes are unsafe or incorrect practices that do not mitigate ignition risks effectively (in fact, rubber sleeves can sometimes trap heat or create alternative hazards if not approved). Therefore, option d (Holstering the electrode when not in use) is the correct choice.
