A client with chronic back pain has an order for a transcutaneous electrical nerve stimulation (TENS) unit for pain control. The nurse should instruct the client to:

1. Keep the unit on high
2. Use the unit when pain is perceived
3. Remove the electrodes at bedtime
4. Use the therapy without medications

ANS: 2
When a client feels pain, the TENS unit is turned on and a buzzing or tingling sensation is creat-ed. The tingling sensation can be applied until pain relief occurs. The client may adjust the inten-sity of skin stimulation. It does not have to remain on high. The electrodes do not have to be re-moved at bedtime. Medication can be administered with a TENS unit.
