A patient is scheduled to have biofeedback therapy for migraine headaches. On arrival to the clinic, the patient appears anxious and fearful and tells the nurse that she does not want electric shocks. The most reassuring response by the nurse is:

The correct answer is C: "There are no electrical shocks involved; the doctor is looking at your body's activity." This response addresses the patient's fear of electric shocks by providing accurate information about the procedure. Biofeedback therapy does not involve electric shocks; instead, it monitors and provides feedback on the body's physiological activities. By reassuring the patient and clarifying the misconception, the nurse can alleviate the patient's anxiety and build trust.

Option A is incorrect as rescheduling the procedure may not address the patient's fear and could further increase anxiety. Option B is incorrect as it does not directly address the patient's concerns and may come off as dismissive. Option D is incorrect as it provides a vague reassurance without addressing the specific fear of electric shocks.
