NIC Esthetician Written ExamSafety and Infection ControlEasy
An esthetician is preparing to use a high-frequency electrode for a client's facial. Before placing the electrode on the client's skin, what crucial safety step must be taken?
- AEnsure the client is holding the indirect electrode.
- BIncrease the intensity setting to the desired level.
- CApply a conductive gel to the client's skin.
- DEnsure the electrode is fully inserted into the handpiece and the power is off.
Show answer & explanationAnswer & explanation
Correct answer: D. Ensure the electrode is fully inserted into the handpiece and the power is off.
Before applying any electrical modality, especially high-frequency, the device should be off, and the electrode securely in place to prevent electrical shock or sparks.
Why the other options are wrong
- A. The client holding an indirect electrode is for a specific indirect high-frequency application, not a universal pre-application step for all electrodes.
- B. Increasing intensity should only be done after the electrode is safely on the skin and the device is turned on, starting from the lowest setting.
- C. Conductive gel is typically not used with high-frequency, as it relies on a gas-filled electrode and direct contact or a gauze barrier.
High-Frequency Pre-Application Safety
Before applying a high-frequency electrode to a client's skin, the device must be off and the electrode securely inserted into the handpiece to prevent electrical shock or sparking.
- Prevents electrical shock or sparking.
- Ensures client comfort and safety.
- Standard safety protocol for electrical modalities.
Memory trick: High-frequency: Power Off, Electrode In, then Glow.
