Before applying a transcutaneous electrical nerve stimulation (TENS) unit, which action is required?

• A. Ensure there is a healthcare provider's prescription for the TENS.
• B. Place the electrodes on the patient without shaving.
• C. Directly apply heat to the treatment area.
• D. Ask the patient to sign a consent form.

Answer: (A)

A healthcare professional’s prescription or order is required before using a transcutaneous electrical nerve stimulation unit. This ensures the device and its settings are appropriate for the patient, taking into account medical history, current condition, and any safety concerns. The prescription guides where to apply the electrodes, the intensity and duration of stimulation, and when to stop if adverse effects occur, helping prevent misuse or harm. Other steps like shaving the skin, applying heat, or having the patient sign a consent form may be part of preparation or standard care, but they do not replace the need for formal authorization to use the device.
