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 B
Explanation
Choice A Reason:
Reporting the client's abnormal lung sounds to the healthcare provider is inappropriate. This option is not appropriate because vesicular breath sounds are actually normal lung sounds. They are soft, low-pitched sounds heard predominantly during inspiration in the peripheral lung fields. Reporting them as abnormal would be incorrect and could potentially lead to unnecessary concern or intervention.
Choice B Reason:
Continuing with the remainder of the client's physical assessment is appropriate. Vesicular breath sounds in the bases of both lungs posteriorly are normal findings. They indicate adequate ventilation and airflow in the lower lung fields. Therefore, there is no need for immediate intervention or further assessment specific to this finding. Continuing with the remainder of the physical assessment is appropriate to assess other aspects of the client's health.
Choice C Reason:
Asking the client to cough and then auscultate at the site again is inappropriate. Asking the client to cough and then auscultate again is not necessary in response to hearing vesicular breath sounds. Vesicular breath sounds are normal lung sounds and do not require further assessment or intervention. Coughing would not change the character of vesicular breath sounds.
Choice D Reason:
Measuring the client's oxygen saturation with a pulse oximeter is inappropriate. While measuring oxygen saturation with a pulse oximeter is an important assessment, it is not specifically indicated in response to hearing vesicular breath sounds. Vesicular breath sounds indicate normal ventilation and airflow in the lower lung fields, but they do not provide direct information about oxygenation status. Oxygen saturation should be assessed as part of a comprehensive respiratory assessment, but it does not need to be prioritized solely based on the finding of vesicular breath sounds.
Correct Answer is ["B","D","E"]
Explanation
Choice A Reason:
Testing feet for a positive Babinski reflex is wrong. The Babinski reflex is a neurological test that assesses upper motor neuron function, particularly in the lower extremities. However, it is not relevant to assessing cold feet, and testing for the Babinski reflex would not provide useful information in this situation.
Choice B Reason:
Observing color of the feet and toes is wright. Observing the color of the feet and toes can provide important information about circulation. Pallor, cyanosis, or mottling may indicate inadequate blood flow or perfusion to the extremities, which could contribute to cold feet.
Choice C Reason:
Measuring skin elasticity around the ankles is wrong. Skin elasticity assessment is more relevant for evaluating hydration status or tissue turgor. While it may be useful in certain contexts, it is not directly related to assessing cold feet and peripheral circulation. Therefore, it is not necessary before covering the client's feet in this scenario.
Choice D Reason:
Assessing volume of the pedal pulses is wright. Assessing the volume of the pedal pulses (such as dorsalis pedis and posterior tibial pulses) provides information about peripheral vascular status. Weak or absent pulses may indicate compromised circulation, contributing to cold feet.
Choice E Reason:
Palpating dorsal surface of feet for warmth is wright. palpating the dorsal surface of the feet for warmth helps assess peripheral perfusion. Coolness to touch may indicate decreased blood flow to the extremities, while warmth suggests adequate circulation.
