A nurse in a prenatal clinic is teaching a client about non pharmacological pain management during labor. Which of the following statements by the client indicates an understanding of the teaching?

A. "The nurse will initiate acupuncture when I arrive at the unit.": Acupuncture must be performed by a trained and licensed practitioner, not a bedside nurse. While it can be used for labor pain, it is not typically initiated by nursing staff upon admission. B. "I can use my ultrasound picture as a focal point during contractions.": Focal point techniques, such as concentrating on a meaningful object like an ultrasound picture, help distract from pain and promote relaxation. C. "A transcutaneous electrical nerve stimulator will help with pelvic pressure.": TENS units are primarily effective for back pain in early labor rather than pelvic pressure. They work by stimulating sensory nerves to reduce pain perception but are less effective for deep pelvic discomfort. D. "My nurse can teach me biofeedback at the beginning of labor.": Biofeedback requires prior training and practice before labor begins to be effective. Learning it for the first time during active labor is impractical and unlikely to yield good results.
