A nurse is performing a neurologic assessment on the client and notes a positive Romberg test. This test for balance is related to which of the following cranial nerves?

VII.

VI.

VIII.

IX.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Cranial nerve VII (Facial nerve) controls muscles of facial expression and functions in taste sensations from the anterior two-thirds of the tongue, not balance.

Choice B rationale

Cranial nerve VI (Abducens nerve) controls lateral eye movement and has no role in balance or proprioception.

Choice C rationale

Cranial nerve VIII (Vestibulocochlear nerve) is responsible for hearing and balance. A positive Romberg test indicates issues with proprioception or vestibular function, which is directly linked to this nerve.

Choice D rationale

Cranial nerve IX (Glossopharyngeal nerve) involves taste sensation from the posterior third of the tongue and some swallowing functions, not balance.

Correct Answer is C

Explanation

Choice A rationale

Deficient fluid volume is not the primary concern related to weight loss or ill-fitting dentures. While fluid intake should be monitored, it is less immediate than gastrointestinal issues from fiber deficiency.

Choice B rationale

Excessive intake of convenience foods might relate to weight loss but does not directly indicate a health risk. The primary risk is more focused on gastrointestinal function.

Choice C rationale

Constipation is a major risk due to limited fiber intake. Fiber is essential for bowel movement regularity, and its deficiency, coupled with ill-fitting dentures, increases the risk.

Choice D rationale

Infection is not directly related to the dietary concerns noted. While poor nutrition can weaken the immune system, it is not the most immediate health risk connected to the given symptoms. .

A. Position the client flat as directed. B. Leave the client to rest and do not perform any assessments. C. Provide caffeine-rich drinks to the client. D. Avoid administering analgesic agents to the client. E. Avoid administering analgesic agents to the client.

Correct Answer is A

Explanation

Choice A rationale

Positioning the client flat as directed is the priority intervention after a lumbar puncture to prevent cerebrospinal fluid (CSF) leakage, which can lead to a post-lumbar puncture headache. This position helps maintain normal CSF pressure and promotes sealing of the puncture site.

Choice B rationale

Leaving the client to rest without performing any assessments is not appropriate, as continuous monitoring is necessary to detect any complications such as bleeding or changes in neurological status. Regular assessments help ensure timely intervention if issues arise.

Choice C rationale

Providing caffeine-rich drinks is sometimes recommended to alleviate headaches caused by CSF leakage post-lumbar puncture. However, it is not the priority intervention immediately after the procedure, which focuses on positioning and monitoring.

Choice D rationale

Avoiding analgesic agents is incorrect. Pain management is an important aspect of care post-lumbar puncture, and appropriate analgesics should be administered as needed. The focus should be on positioning and monitoring, not withholding pain relief.
