A client experiencing chronic back pain asks how a TENS unit works. Which of the following should the nurse teach the patient?
1. The TENS unit produces a tingling or vibrating sensation, which stimulates nonpain receptors.
2. The TENS unit alternates heat and cold to decrease inflammation and promote vasodilation.
3. The TENS unit provides for a slow release of non-narcotic analgesic that is absorbed through the skin.
4. The TENS unit promotes muscle relaxation through a biofeedback mechanism.
The TENS unit produces a tingling or vibrating sensation that stimulates nonpain receptors.
Rationale: The TENS unit is applied to the site of pain and emits a low-level electrical stimulation that produces a tingling or vibrating sensation; this stimulates nonpain receptors and interferes with pain perception. The TENS unit does not provide heat/cold, release medications, or work through biofeedback.
