A licensed esthetician wants to perform a direct-application high-frequency facial. Which client condition is an ABSOLUTE contraindication that prohibits the treatment?
Explanation
High-frequency current uses an oscillating alternating current that produces a small electromagnetic field at the electrode. That field can interfere with implanted cardiac pacemakers and other electronic medical devices, so a pacemaker is an absolute contraindication for high-frequency, galvanic, and microcurrent services. California estheticians performing electrotherapy must screen for this on the consultation form, consistent with the safe-equipment-use duties of CCR Title 16 §979.2. Pregnancy, metal implants in the treatment area, epilepsy, and severe heart disease are additional contraindications. Options A, B, and C are not contraindications; they describe ordinary client conditions.
