Correct answer: D — Ultrasonic scaler (magnetostrictive type)

Magnetostrictive ultrasonic scalers generate electromagnetic fields that can potentially interfere with older pacemaker models, although modern bipolar pacemakers are better shielded. As a precaution, many guidelines recommend avoiding magnetostrictive ultrasonic scalers in patients with cardiac pacemakers and using piezoelectric scalers (which do not generate significant electromagnetic interference) or hand instruments instead. The patient's cardiologist should be consulted regarding the specific device model and its susceptibility to EMI. Electric pulp testers should also be avoided.
