Consider the following test: 1. Assess pupillary light reaction. Conduct this test in an area with reduced light. Standing directly in front of your patient and using a pen light, start by shining the light at the patient's right ear. Pass the light across the right eye. Observe the pupil size in the right eye as well as the left eye. 2. Assess patient's ability to follow your finger with his/her eye without moving his/her head. Move the finger in an 'H' pattern to assess upward, downward and lateral movements. 3. Assess convergence: examiner should move finger towards patient's nose. What cranial nerve(s) is/are being tested with the tests above? Explain your rationale.
