The nurse is assessing the 6 stages of cardinal gaze. This test assesses:
Cranial nerves III, IV, and X for eye muscle strength.
Cranial nerves III, IV, and VI for ocular motor movements.
Cranial nerves IV, V and VII for visual accuracy.
Cranial nerve II for visual acuity.
The Correct Answer is B
The nurse is assessing the 6 stages of the cardinal gaze to evaluate the function of the cranial nerves III, IV, and VI for ocular motor movements, which control eye movement and positioning.
Cranial nerve III controls the superior rectus, inferior rectus, and medial rectus muscles, which move the eye up, down, and inward, respectively. Cranial nerve IV controls the superior oblique muscle, which moves the eye downward and laterally. Cranial nerve VI controls the lateral rectus muscle, which moves the eye outward.
Therefore, the nurse will observe the patient's ability to move their eyes smoothly in each of the six cardinal positions of gaze and note any abnormalities that may indicate dysfunction of these cranial nerves. This test is used to diagnose conditions such as strabismus, nystagmus, and palsy of the ocular motor nerves.
Cranial nerve II, on the other hand, is responsible for visual acuity, not eye movement, and is tested separately using a visual acuity chart or other vision tests.

Explanation
The nurse would describe this as tinnitus, which is a sensation of hearing sound when no external sound is present. Tinnitus is commonly described as ringing in the ears, but can also be perceived as buzzing, humming, hissing, or other sounds. Tinnitus can be caused by a variety of factors, including age-related hearing loss, exposure to loud noises, ear infections, certain medications, and underlying medical conditions such as high blood pressure, thyroid disorders, or head and neck injuries. It is important for the patient to see a healthcare provider to determine the underlying cause and appropriate treatment.
