A dental assistant accidentally exposed to a contaminant on the skin should first do what?

  1. Apply an antiseptic

  2. Wash the exposed skin with soap and water

  3. Cover the area with a sterile bandage

  4. Immediately see a doctor

The correct answer is: Wash the exposed skin with soap and water

Washing the exposed skin with soap and water is the first step that should be taken by a dental assistant who has been accidentally exposed to a contaminant on the skin. This is because soap and water can effectively remove most contaminants and reduce the risk of further absorption into the skin. Applying an antiseptic may also be helpful, but it should only be done after washing with soap and water. Covering the area with a sterile bandage or immediately seeing a doctor are not necessary in this situation as the skin can be cleaned with soap and water.
