Answer to Question 1

Correct Answer: 3

The superior, middle, and inferior turbinates are specifically responsible for warming, moistening, and filtering the air before it enters the trachea and lungs. The olfactory cells assist the client to smell. The columella is located at the base of the nose and helps form the nares. The nares are structures that lead into the internal vestibule and nasal cavity.

Answer to Question 2

Correct Answer: 1
The sense of smell is controlled by cranial nerve I. Tongue movement is controlled by cranial nerve XII. The sense of taste is controlled by cranial nerves VII and IX. Hearing and balance is controlled by cranial nerve VIII.
