Before beginning a current-based treatment, what should be the state of the current?

• A. On
• B. Standby
• C. Low
• D. Off

Answer: (D)

The basic safety concept here is that a current-based device should be completely inactive before you begin. Being in the Off state ensures no electrical current is flowing and no energy is delivered to the skin, which is essential when you’re setting up electrodes, positioning the client, or adjusting parameters. This minimizes the risk of accidental shocks or unintended stimulation during setup. If you were to leave the device On, current could start extending to the treatment area as soon as a trigger or setting is engaged, which is unsafe during patient prep. A standby state might keep the system partly ready, but it can still carry risk of unexpected activation or residual activity, so it isn’t as safe as having the device fully Off. A Low setting implies some current is present, which is clearly incompatible with the preparation phase. So, the safest and most appropriate state before beginning a current-based treatment is Off.
