A client with chronic pain has been taught how to operate a transcutaneous electrical nerve stimulation (TENS) unit. Which client action shows understanding of the appropriate use of the device when the level of stimulation is uncomfortable?

The client marginally changes the setting downwards.

Explanation:

Through putting two electrodes on the skin and changing the stimulation rate to one lead at a time, the client applies a transcutaneous electrical nerve stimulator.

The volume of stimulation is raised until the client experiences discomfort, meaning that the total stimulus needed to block unpleasant stimuli has been achieved.

The frequency is then slightly reduced until there is no further pain. All other choices are the wrong ones.
