Proper ergonomic positioning when working from the operator's location includes what?

  1. Positioning the knees below the hips

  2. Leaning forward slightly at the waist

  3. Positioning the elbows close to the body

  4. Stretching the arms out towards the patient

The correct answer is: Positioning the elbows close to the body

Proper ergonomic positioning when working from the operator's location includes positioning the elbows close to the body. This is because it helps reduce strain and tension on the arms, shoulders, and neck, as well as promoting good posture and preventing musculoskeletal disorders. Option A is incorrect because positioning the knees below the hips puts unnecessary strain on the lower back and can lead to discomfort and pain. Option B is incorrect because leaning forward at the waist can cause strain on the neck and shoulders, leading to tension and discomfort. Option D is incorrect because stretching the arms out towards the patient can cause strain on the shoulders, neck, and upper back due to the weight of the arms being unsupported.
