How does a nurse perform the confrontation test for assessing a client's peripheral vision?

A nurse performs the confrontation test for assessing a client's peripheral vision by sitting at eye level with the client, covering one eye, and bringing an object into the visual field. This method allows the nurse to compare the peripheral vision of both the client and themselves, as the nurse should be able to see the object entering their own peripheral vision at the same time the client does.

By positioning themselves at eye level and using the cover technique, the nurse ensures that any discrepancies in peripheral vision can be accurately identified. This test is specifically designed to evaluate the extent and integrity of the visual fields, which can reveal issues related to optic nerve function or neurological conditions.

The other methods mentioned, such as reading an eye chart or using a flashlight, do not assess peripheral vision specifically. Using a mirror might provide a different perspective but does not effectively test the visual fields in the same direct and comparative manner as the confrontation test.
