Question 1 of 5
A nurse is assessing a client's cranial nerves as part of a neurological examination. Which of the following actions should the nurse take to assess cranial nerve III?
Correct Answer: A
Rationale: The correct answer is A: Checking the pupillary response to light. Cranial nerve III, also known as the oculomotor nerve, controls the pupillary response to light.
To assess this nerve, the nurse should shine a light into the client's eyes and observe the pupillary constriction in response to the light stimulus. This tests the integrity of cranial nerve III, which controls the constriction of the pupils.
Other choices are incorrect because:
B: Eliciting the gag reflex - This tests cranial nerves IX (glossopharyngeal) and X (vagus), not cranial nerve III.
C: Testing visual acuity - This assesses the function of the optic nerve (cranial nerve II), not cranial nerve III.
D: Observing for facial symmetry - This evaluates cranial nerve VII (facial nerve) function, not cranial nerve III.
