In relation to the operator, how is the assistant positioned?

  1. Directly opposite to the operator

  2. 4-6 inches higher than the operator

  3. At the same height as the operator

  4. 4-6 inches lower than the operator

The correct answer is: 4-6 inches higher than the operator

The assistant is positioned 4-6 inches higher than the operator in order to maintain a clear line of sight and provide better support and assistance during procedures. Option A is incorrect because being directly opposite to the operator could obstruct their view and potentially create obstacles in their work. Option C is incorrect because being at the same height as the operator could lead to difficulties in reaching equipment and instruments. Lastly, option D is incorrect because being 4-6 inches lower than the operator could cause strain on the assistant's neck and back.
