During continuous ultrasound treatment, if a patient reports feeling an electrical shock, what is the most appropriate action for the therapist?

In the scenario where a patient reports feeling an electrical shock during continuous ultrasound treatment, the most appropriate action for the therapist is to unplug the machine and label it as "defective, do not use." This approach prioritizes patient safety and indicates a serious issue with the equipment, as electrical shocks suggest a malfunction or risk of injury. Ensuring that the device is marked and removed from use prevents further risk to other patients and allows for proper maintenance or inspection.

When a patient experiences discomfort or an unusual sensation during treatment, it is critical to address the situation immediately. The manifestation of electrical shock implies that the ultrasound machine may be malfunctioning, and taking the necessary steps to prevent potential harm is essential. Once the machine is unplugged and labeled, it can be inspected or repaired as needed, ensuring the safety and well-being of future patients.

While decreasing the intensity of the ultrasound or modifying the duty cycle may seem like reasonable steps to alleviate discomfort in some situations, they do not address the underlying risk of electrical shock and do not effectively mitigate the safety concern. Discontinuing ultrasound treatment is an important step in ensuring patient welfare, but the action of unplugging and labeling the device conveys a more proactive approach to preventing future incidents.
