On assessment of the client's tongue, the client is unable to protrude the tongue and has poor strength on testing against resistance.
This would indicate dysfunction of which cranial nerve?
Optic nerve.
Abducens nerve.
Hypoglossal nerve.
Vestibulocochlear nerve.
The Correct Answer is C
Choice A rationale
The optic nerve (CN II) is responsible for vision. It transmits visual information from the retina to the brain. Dysfunction in this nerve typically results in visual disturbances such as loss of vision, visual field defects, or difficulty in distinguishing colors. It does not control the movement or strength of the tongue.
Choice B rationale
The abducens nerve (CN VI) innervates the lateral rectus muscle of the eye, which is responsible for abducting the eye (moving it outward). Dysfunction in this nerve can lead to strabismus (misalignment of the eyes), double vision, or inability to move the eye outward. It does not affect tongue movement or strength.
Choice C rationale
The hypoglossal nerve (CN XII) innervates the muscles of the tongue, controlling its movement and strength. Dysfunction in this nerve can result in difficulty protruding the tongue, poor strength against resistance, and impaired speech or swallowing. Therefore, the symptoms described in the question indicate a dysfunction of the hypoglossal nerve.
Choice D rationale
The vestibulocochlear nerve (CN VIII) is responsible for hearing and balance. It transmits sound and equilibrium information from the inner ear to the brain. Dysfunction in this nerve can lead to hearing loss, tinnitus, vertigo, or balance problems. It does not control tongue movement or strength.

Correct Answer is C
Explanation
Choice A rationale
Leukoplakia refers to white patches or plaques that develop on the mucous membranes of the oral cavity. It is usually seen as a precancerous condition and is associated with chronic irritation, smoking, or other risk factors. These white patches are not typically associated with redness and bleeding of the gums.
Choice B rationale
Gingival hyperplasia involves the overgrowth or enlargement of the gums. It can be due to various factors, including medications (such as anticonvulsants or calcium channel blockers), hormonal changes, or certain systemic conditions. While the gums may appear enlarged and possibly bleed, gingival hyperplasia is not characterized by redness and bleeding as primary symptoms.
Choice C rationale
Gingivitis is the inflammation of the gums (gingiva) and is characterized by redness, swelling, and bleeding. It is usually caused by plaque buildup along the gumline, leading to irritation and inflammation. Gingivitis is considered an early stage of gum disease and can be reversed with proper oral hygiene and dental care.
Choice D rationale
Periodontitis is an advanced stage of gum disease that occurs when gingivitis is left untreated. It involves the destruction of the supporting structures of the teeth, including the alveolar bone and periodontal ligaments. Symptoms of periodontitis include gum recession, pockets forming between the gums and teeth, and possible tooth loss. While periodontitis can lead to bleeding gums, it is more severe than the initial symptoms of redness and bleeding seen in gingivitis.
Correct Answer is A
Explanation
Choice A rationale
The general survey is an overall assessment of a client's physical appearance, behavior, mobility, and neurological status. It provides a comprehensive overview of the client's health and well-being, making it the focus of the nurse's observations in this scenario.
Choice B rationale
Medical history includes past and current health conditions, surgeries, medications, and family health history. While important, it is not the focus of the nurse's immediate observations in this scenario.
Choice C rationale
Biographical data involves personal information such as age, gender, occupation, and marital status. While relevant to the client's health, it is not the primary focus of the nurse's observations in this scenario.
Choice D rationale
Social history includes information about the client's lifestyle, habits, and social environment. While valuable for understanding the client's overall health context, it is not the focus of the nurse's immediate observations in this scenario. .
