Which cranial nerve is responsible for muscles that move the eye and lids?

Oculomotor.

Vestibulocochlear.

Facial.

Trigeminal.

Answer and Explanation

The Correct Answer is A

Choice A rationale

The oculomotor nerve (cranial nerve III) is responsible for innervating the muscles that move the eye and lift the eyelid, as well as controlling pupil constriction and lens shape for focusing.

Choice B rationale

The vestibulocochlear nerve (cranial nerve VIII) is involved in hearing and balance, not in the movement of eye muscles or eyelids.

Choice C rationale

The facial nerve (cranial nerve VII) controls muscles of facial expression, taste sensations from the anterior two-thirds of the tongue, and functions in tear and saliva production.

Choice D rationale

The trigeminal nerve (cranial nerve V) is responsible for sensation in the face and motor functions such as biting and chewing, not for eye movements.

Correct Answer is A

Explanation

Choice A rationale

Expressing satisfaction with the ability to perform Activities of Daily Living (ADLs) is a realistic and client-centered goal for managing osteoarthritis. It focuses on the client's quality of life and functional ability, which is essential in chronic conditions like OA.

Choice B rationale

Adhering to the prescribed plan of care is important for managing OA, but it is more of an ongoing process than a specific goal. The focus should be on the client's functional outcomes and overall well-being.

Choice C rationale

Osteoarthritis is a chronic condition that cannot be cured within six months. Recovery in the context of OA usually refers to managing symptoms and improving quality of life rather than a complete resolution of the disease.

Choice D rationale

Denying signs or symptoms of OA is unrealistic for a chronic condition. The goal should be managing symptoms effectively and maintaining functional ability rather than complete absence of symptoms.

A. Fever. B. Visual disturbance. C. Gait alteration. D. Hypoxia.

Correct Answer is D

Explanation

Choice A rationale

Fever is typically regulated by the hypothalamus, a part of the brain that controls body temperature. Dysfunction of the lower brain stem does not typically cause fever.

Choice B rationale

Visual disturbances are often related to issues with the visual cortex or optic pathways, which are not part of the lower brain stem.

Choice C rationale

Gait alteration is typically associated with dysfunction in the cerebellum or motor pathways, rather than the lower brain stem.

Choice D rationale

Hypoxia, or decreased oxygen levels, can be a critical concern with lower brain stem dysfunction as the lower brain stem controls vital autonomic functions such as respiration and heart rate.
