Question

While examining your patient's head and face, you determine that cranial nerve I is intact when the patient follows your instructions and successfully ________.

Answer 1

In testing the patient's sense of smell, if they can correctly identify different scents using one nostril at a time, it indicates that cranial nerve I is intact.

Step-by-step explanation:

When examining a patient's head and face, determining that cranial nerve I is intact is typically done by testing the patient's sense of smell. The patient is asked to identify different scents, such as coffee or mint, using one nostril at a time. If the patient can correctly identify the scents, it indicates that cranial nerve I, also known as the olfactory nerve, is functioning properly.
