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 C
Explanation
Choice A Reason:
Sending the sample for laboratory evaluation is incorrect. Sending the urine sample for laboratory evaluation is a standard procedure to assess for any abnormalities, such as urinary tract infections (UTIs), kidney function, or other urinary tract disorders. While laboratory evaluation of the urine sample is important for diagnostic purposes, the client's difficulty providing an adequate urine sample suggests an underlying issue that needs to be addressed before obtaining a sample.
Choice B Reason:
Giving the client 8 ounces (236.5 mL) of water to drink is incorrect. Offering the client water to drink is a common intervention to encourage urine production and facilitate urine sample collection, particularly if the client is dehydrated or has difficulty producing a sample. However, given the client's symptoms of lower abdominal discomfort, frequent urination, and difficulty providing a urine sample despite efforts, simply offering water may not adequately address the underlying issue of potential bladder distention.
Choice C Reason:
Evaluating the client for bladder distention is correct. The client's symptoms of lower abdominal discomfort, frequent urination, and difficulty providing a urine sample after an extended period of time, along with returning with only a few drops of urine, are suggestive of potential bladder distention. Evaluating the client for bladder distention involves assessing for signs such as a visibly enlarged and palpable bladder, suprapubic discomfort or pain, and percussion of the bladder to assess for dullness, indicating fluid accumulation. Addressing bladder distention is essential to ensure the client's comfort and prevent complications associated with urinary retention.
Choice D Reason:
Instructing the client to attempt to urinate again is incorrect. Instructing the client to attempt to urinate again may be a reasonable intervention if the bladder is not distended and the client is simply having difficulty producing a urine sample. However, given the client's symptoms and the difficulty providing an adequate urine sample despite previous attempts, simply instructing the client to try again may not address the underlying issue of potential bladder distention. Evaluating for bladder distention is necessary to determine the appropriate course of action and ensure the client's comfort and safety.
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.
