Question 1 of 5
A nurse is preparing to test cranial nerve I. Which item does the nurse obtain to test this nerve?
Correct Answer: C
Rationale:
To assess the function of cranial nerve I (olfactory nerve), the nurse uses a wisp of cotton to test the sense of smell in a client who reports loss of smell. The nurse assesses the patency of the client's nostrils by occluding one nostril at a time and asking the client to sniff. Next, with the client's eyes closed, the nurse occludes one nostril and presents a non-noxious aromatic substance such as coffee, toothpaste, orange, vanilla, soap, or peppermint.
Choice A, 'Coffee,' is incorrect because it is used to present non-noxious aromatic substances to assess cranial nerve I.
Choice B, 'A tuning fork,' is used to assess the function of cranial nerve VIII (acoustic nerve).
Choice D, 'An ophthalmoscope,' is used to assess the internal structures of the eye, not cranial nerve I.
