Final answer:
To assess cranial nerve VII, which is the facial nerve, a nurse would conduct tests involving facial expressions and symmetry to identify any potential weakness or paralysis.
Step-by-step explanation:
To assess the function of cranial nerve VII, also known as the facial nerve, a nurse would perform specific tests as part of the cranial nerve exam. This nerve is responsible for controlling the muscles of facial expression, taste sensation from the anterior two-thirds of the tongue, and other functions.
A common test for assessing the facial nerve is to ask the patient to perform tasks such as wrinkling their forehead, closing their eyes tightly, showing their teeth, smiling, and puffing out their cheeks. The health care professional might also assess for symmetry in the face while the patient performs these tasks.
By doing so, the nurse can determine if there is any weakness or paralysis in the facial muscles, which could indicate a dysfunction of cranial nerve VII.
