The nurse continues a neurologic assessment of the cranial nerve XI (Spinal accessory) for a client. Which instruction should the nurse give the client to complete this assessment?
Shrug shoulders against resistance.
Stand up slowly with eyes closed.
Turn head from side to side.
Raise both arms overhead
The Correct Answer is A
Choice A Reason:
Shrug shoulders against resistance is correct because cranial nerve XI, also known as the spinal accessory nerve, innervates the trapezius and sternocleidomastoid muscles. Instructing the client to shrug their shoulders against resistance tests the strength and function of the trapezius muscle, which is primarily innervated by cranial nerve XI. Therefore, this instruction directly assesses the function of the cranial nerve XI.
Choice B Reason:
Stand up slowly with eyes closed is incorrect because standing up slowly with eyes closed primarily assesses proprioception and balance, which involve multiple cranial nerves and the vestibular system. While cranial nerve XI may play a role in maintaining posture and balance, it is not the primary nerve involved in this assessment.
Choice C Reason:
Turn head from side to side is incorrect because turning the head from side to side primarily assesses the function of the sternocleidomastoid muscle, which is also innervated by cranial nerve XI. However, this action alone does not provide resistance against which the muscle can contract, making it less specific for assessing cranial nerve XI compared to the instruction to shrug the shoulders against resistance.
Choice D Reason:
Raise both arms overhead incorrect because raising both arms overhead primarily assesses motor function and strength of the upper extremities, which do not directly involve the muscles innervated by cranial nerve XI. While the trapezius muscle may be indirectly involved in shoulder movement, this action does not specifically target the function of cranial nerve XI.

Correct Answer is D
Explanation
a. "Motor responses."Motor responses are important in assessing neurological function, but they are typically assessed after determining the client's overall level of consciousness and alertness. Motor responses are usually assessed when the client is unresponsive or has altered consciousness.
b. "Eye opening."Eye opening is part of the Glasgow Coma Scale (GCS) and is an important indicator of neurological function. However, it is generally assessed after determining the client's level of alertness.
c. "Verbal response."Verbal response is another component of the GCS, assessing how the client responds to verbal stimuli. This assessment also follows the initial determination of the client’s alertness.
d. "Level of alertness."The level of alertness is the first and most fundamental aspect to assess because it gives the nurse a baseline understanding of how aware the client is of their surroundings. This assessment sets the stage for further evaluation of motor, eye, and verbal responses. It helps determine the client's ability to interact and respond to stimuli, guiding subsequent assessments.
Correct Answer is C
Explanation
Choice A Reason:
Observing for jugular vein distention while the client is flat in bed is incorrect because jugular vein distention is not directly related to orthopnea. Jugular vein distention may indicate increased central venous pressure, which can occur in conditions such as heart failure, but it is not specific to orthopnea, which is difficulty breathing while lying flat.
Choice B Reason:
Measuring the client's blood pressure when he is lying and standing is incorrect because measuring blood pressure in different positions (lying and standing) is used to assess for orthostatic hypotension, not orthopnea. Orthostatic hypotension refers to a drop-in blood pressure upon standing and is not directly related to difficulty breathing while lying flat.
Choice C Reason:
Asking the client how many pillows he sleeps on at night is correct because orthopnea is characterized by difficulty breathing while lying flat, often relieved by sitting up or propping oneself with pillows. Asking the client how many pillows he sleeps on at night provides valuable information about his sleeping position and potential orthopnea. Clients with orthopnea often need to sleep in a semi-upright position or with multiple pillows to alleviate breathing difficulties.
Choice D Reason:
Auscultating the client's breath sounds while he is supine is incorrect because auscultating the client's breath sounds while he is supine may provide information about lung sounds, but it does not specifically assess for orthopnea. Orthopnea refers to difficulty breathing while lying flat, and the assessment of breath sounds may not directly indicate this condition.
