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:

"You seem too anxious for this procedure. Let's reschedule it at another time."

"Didn't the doctor explain this procedure to you?"

"There are no electrical shocks involved; the doctor is looking at your body's activity."

"Don't worry; this will not hurt a bit."
