While assessing a client's musculoskeletal status, the nurse asks the client to perform lateral bends. Which of the following will this movement provide information about?

Range of motion

Diaphragmatic excursion

Spinous processes

Spinal deformities

Answer and Explanation

The Correct Answer is A

A) Range of motion: Lateral bending of the spine is a movement used to assess the range of motion (ROM) of the spine, specifically the flexibility and mobility of the thoracolumbar region. By asking the client to perform lateral bends, the nurse can evaluate the extent to which the client can bend sideways and assess any limitations or discomfort in the movement.
B) Diaphragmatic excursion: Diaphragmatic excursion refers to the movement of the diaphragm during respiration and is assessed through techniques like percussion and auscultation of the lungs. Lateral bending of the spine does not provide information about diaphragmatic movement.
C) Spinous processes: The spinous processes of the vertebrae can be palpated to assess alignment and tenderness, but lateral bending does not specifically assess the spinous processes. It focuses more on the overall mobility of the spine.
D) Spinal deformities: While lateral bending can reveal limitations in spinal movement that might suggest underlying spinal deformities, it is not a primary diagnostic tool for identifying specific deformities. Other assessments, such as inspection and palpation of the spine, X-rays, or physical

Correct Answer is B

Explanation

A) XI: Cranial nerve XI, the spinal accessory nerve, is primarily responsible for motor function, particularly in the muscles involved in shoulder elevation and head rotation. It does not play a role in balance, so focusing on this nerve would not be relevant to the client’s complaint of balance issues.
B) VIII: Cranial nerve VIII, the vestibulocochlear nerve, is directly involved in hearing and balance. It transmits information from the inner ear to the brain regarding head position and motion, which are essential for maintaining balance. The client’s report of spontaneous loss of balance strongly suggests involvement of this nerve, making it the most appropriate focus for additional assessment.
C) IX: Cranial nerve IX, the glossopharyngeal nerve, is primarily associated with taste and the gag reflex. While it is important for swallowing and certain aspects of speech, it does not influence balance, so it would not be the primary concern in this situation.
D) X: Cranial nerve X, the vagus nerve, has extensive functions related to autonomic control of the heart, lungs, and digestive tract, as well as motor and sensory functions in the throat. Although it plays a significant role in the body, it does not directly influence balance, making it less relevant in this context.

A. lateralization of the sound/vibration to both ears equally B. lateralization of the sound/vibration to the left ear. C. bone conduction(BC) is greater than air conduction (AC) D. lateralization of the sound/vibration to the right ear.

Correct Answer is B

Explanation

A) Lateralization of the sound/vibration to both ears equally: The Weber test is used to assess unilateral hearing loss and would not show equal lateralization in the presence of unilateral sensorineural hearing loss. Equal lateralization would suggest normal hearing or symmetrical hearing loss, which is not the case here.
B) Lateralization of the sound/vibration to the left ear: In sensorineural hearing loss, sound is perceived to lateralize to the unaffected ear. Therefore, with right ear sensorineural hearing loss, the sound will lateralize to the left ear, indicating that the left ear has better hearing capability.
C) Bone conduction (BC) is greater than air conduction (AC): This finding is characteristic of conductive hearing loss, not sensorineural hearing loss. In sensorineural hearing loss, air conduction is typically greater than or equal to bone conduction, but the Weber test focuses on lateralization rather than BC versus AC.
D) Lateralization of the sound/vibration to the right ear: If the sound were to lateralize to the affected ear in sensorineural hearing loss, it would suggest that the affected ear is hearing better, which contradicts the nature of sensorineural hearing loss. The sound will actually lateralize to the better-hearing, unaffected ear.
