If a patient starts to have a seizure during photic stimulation, what should the technologist do first?

In the scenario where a patient begins to have a seizure during photic stimulation, turning off the photic stimulator is the most appropriate first action. Initiating a seizure can pose significant risks to the patient's safety and well-being. Photic stimulation is used to evoke brain responses in a controlled environment; however, if a seizure occurs, the immediate priority is to reduce any potential triggers, which includes ceasing the photic stimuli that could be exacerbating the situation.

Once the photic stimulation is turned off, the technologist can then focus on the patient's safety, assess the situation further, and take necessary additional actions such as notifying medical personnel or documenting the event. This sequence ensures that the well-being of the patient is prioritized while also maintaining a safe testing environment.
