The PMHNP has just diagnosed a 7-year-old boy with attention-deficit hyperactivity disorder (ADHD). The boy's mother is adamant she does not want him to take medication, and she asks the PMHNP to tell her about biofeedback. Which of the following is the best response?

"Biofeedback teaches a patient to control their own physiologic responses."

"Biofeedback stimulates the olfactory system to elicit feelings and memories."

"Biofeedback aids in the activity of endorphins by manipulating points of energy flow in the body."

"Biofeedback increases blood circulation, improves lymph flow, and enhances musculoskeletal tone."
