2024 PN NCLEX Questions Nursing Practice Question
A nurse is preparing to test cranial nerve I. Which item does the nurse obtain to test this nerve?
Correct Answer: C
Rationale: Cranial nerve I, the olfactory nerve, is responsible for the sense of smell. To effectively test this nerve, a substance with a distinct scent, such as coffee, is ideal. However, while coffee (Option A) could serve this purpose, it is not a standard testing item. A tuning fork (Option B) is used for auditory tests, assessing cranial nerves related to hearing, not smell. An ophthalmoscope (Option D) is designed for examining the eyes and does not pertain to olfactory function. Thus, a wisp of cotton (Option C) is the most appropriate choice, as it can be used to deliver a scent for olfactory testing.
