While cleaning contaminated instruments, an assistant receives a percutaneous injury to the finger. The assistant should FIRST do what?

  1. Report to a supervisor

  2. Apply a bandage

  3. Wash hands with soap and water

  4. Disinfect the wound with alcohol

The correct answer is: Wash hands with soap and water

After sustaining a percutaneous injury, the first step an assistant should take is to wash their hands with soap and water. This is important because it helps to prevent the spread of any potential infection. Applying a bandage or disinfecting the wound with alcohol can come after washing hands, but they are not the first priority. Reporting to a supervisor may also be necessary, but it is not the immediate action that should be taken.
