Trochlear

Optic

Oculomotor

Abducens

Answer and Explanation

Correct Answer : A,C,D

A) Trochlear: The trochlear nerve (CN IV) is responsible for innervating the superior oblique muscle, which helps control the downward and inward movement of the eye.
B) Optic: The optic nerve (CN II) is primarily involved in vision and visual acuity, not in the movement of the eye. It transmits visual information from the retina to the brain.
C) Oculomotor: The oculomotor nerve (CN III) controls most of the extraocular muscles, including those responsible for eye movement (superior rectus, inferior rectus, medial rectus, and inferior oblique) and also controls pupil constriction.
D) Abducens: The abducens nerve (CN VI) controls the lateral rectus muscle, which is responsible for the outward movement of the eye.
E) Facial: The facial nerve (CN VII) controls the muscles of facial expression and is not involved in eye movements.

Correct Answer is ["A","C","D"]

Explanation

A. Weber test: The Weber test is used to assess hearing by placing a vibrating tuning fork on the center of the forehead. It helps evaluate lateralization of sound and can indicate whether hearing loss is conductive or sensorineural. This test is pertinent for assessing CN VIII, which is responsible for hearing.
B. Magazine: This option is not relevant to the assessment of CN VIII. A magazine is not used in evaluating hearing or vestibular function. The appropriate assessments for CN VIII focus on hearing and balance.
C. Rinne test: The Rinne test involves placing a vibrating tuning fork on the mastoid bone and then near the ear canal to compare air conduction (AC) and bone conduction (BC) of sound. This test helps differentiate between conductive and sensorineural hearing loss and is directly related to assessing CN VIII.
D. Whispered voice test: This test involves the nurse whispering numbers or words while occluding one ear and assessing the client's ability to hear and repeat them. It is a simple way to assess hearing ability and thus evaluates the function of CN VIII.

A. glenohumeral joint B. sternoclavicular joint C. temporomandibular joint D. acromioclavicular joint

Correct Answer is C

Explanation

A. Glenohumeral joint: The glenohumeral joint is the shoulder joint. Pain with chewing is unlikely to be related to issues with the shoulder joint, as this joint is not involved in the chewing process.

B. Sternoclavicular joint: The sternoclavicular joint is where the clavicle meets the sternum. Problems here might affect shoulder and chest movement, but they would not typically cause pain specifically related to chewing.
C. Temporomandibular joint (TMJ): The TMJ is directly involved in the movement of the jaw, which is essential for chewing. Chronic pain during chewing often indicates a problem with the TMJ, such as TMJ disorder, which can cause pain, clicking, and other issues when moving the jaw.
D. Acromioclavicular joint: The acromioclavicular joint is located at the top of the shoulder where the clavicle meets the acromion of the scapula. This joint primarily affects shoulder movement, not chewing.
