The nurse positions a patient for an eye examination. After repeated attempts, the patient is able to read all the letters on the Snellen chart without difficulty at a distance of 15 feet. From this finding the nurse determines that the patient:
1. has normal 20/20 vision.
2. has normal reading vision.
3. has visual impairments.
4. has a normal pupillary reflex.
Correct Answer: 3
The patient must stand closer than normal to read the chart. For people with normal vision, the distance from the viewed object at which the eyes require no accommodation is 20 feet. This test is not used to assess reading vision or pupillary reflex.
