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.

Answer and Explanation

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 A

Explanation

Choice A rationale

Flatness is the percussion sound typically heard over muscles and solid tissues. It is characterized by a high-pitched, soft sound, which indicates that the underlying tissue is denser and less air-filled compared to lungs.

Choice B rationale

Dullness is heard over solid organs such as the liver or spleen but not typically over muscles.

Choice C rationale

Tympany is a drum-like sound heard over areas filled with gas, such as the stomach or intestines.

Choice D rationale

Resonance is heard over air-filled lungs and not over muscles and solid tissues.

A. Caused by the complete absence of melanin pigment. B. Caused by an excess of apocrine glands in her feet. C. Related to impetigo and can be treated with an ointment. D. Caused by an excess of melanin pigment.

Correct Answer is A

Explanation

Choice A rationale

Vitiligo is a condition caused by the destruction or malfunction of melanocytes, the cells responsible for producing melanin pigment. This leads to the development of white patches on the skin, as melanin is absent in these areas. Vitiligo is an autoimmune condition and can affect any part of the body, including the skin, hair, and mucous membranes.

Choice B rationale

Excess apocrine glands in the feet are not related to vitiligo. Apocrine glands are sweat glands found primarily in the underarm and genital areas and are responsible for the secretion of a thick, odorless fluid. Their overactivity does not result in the white patches seen in vitiligo.

Choice C rationale

Impetigo is a bacterial skin infection characterized by red sores, blisters, and crusting. It is not related to vitiligo and does not cause depigmentation. Impetigo is treated with antibiotics, whereas vitiligo requires different management strategies to address the loss of pigment.

Choice D rationale

Vitiligo is not caused by an excess of melanin pigment. Rather, it is the result of melanin loss or the absence of melanocytes in certain areas of the skin, leading to the characteristic white patches.
