What instruction should the nurse include in the discharge teaching plan of a client who has a transcutaneous electrical nerve stimulation (TENS) unit?
a. "Pain relief is sustained when stimulation is stopped."
b. "The current is adjusted by the physician."

D
The TENS unit works through electrodes that are placed near the painful area site. These elec-trodes are connected to a small box that contains the current needed for pain relief. The current can be adjusted by any health care provider. Adjustment of this current can cause a pins and needles sensation. Pain relief with cutaneous therapy generally is sustained only as long as the stimulation continues.
