Answer to Question 1

ANS: B
Cranial nerve III (oculomotor nerve) is assessed by observing the patient's pupil size and reaction to light and the direction of gaze. Identifying a common scent would test cranial nerve I. Assessing the patient's visual acuity tests cranial nerve II. Assessing hearing is cranial nerve VIII.

Answer to Question 2

ANS: A
Cranial nerve VI (abducens) is responsible for outward gaze of the eyes. Abnormal findings could indicate a fracture of the orbit or a brain tumor. The nurse asks the patient questions related to these two conditions. The provider needs to be informed and the nurse must document, but first the nurse conducts a thorough assessment. Frowning and lifting the eyes assesses cranial nerve VII.
