Practice Question
A nurse is assessing a client's cranial nerves. Which of the following methods should the nurse use to assess cranial nerve II?
Answer Choices:
Correct Answer:
Ask the client to read a Snellen chart.
Rationale:
📌Cranial nerve II (optic nerve) mediates visual acuity and visual fields.
📌Using a Snellen chart allows the nurse to objectively measure distance vision, which is the primary function of this nerve.
📌Other methods, like assessing speech or scent detection, evaluate different cranial nerves (VII, VIII, I), not CN II.
📌Testing visual acuity provides baseline information for neurologic assessment, helps detect optic nerve damage, and identifies early signs of visual impairment.
📌Regular CN II assessment is particularly important in clients with conditions that can compromise vision, such as hypertension, diabetes, or neurologic disorders.
