The physician has ordered a somatosensory evoked responses (SERs) test for a patient for whom the nurse is caring. The nurse is justified in suspecting that this patient may have a history of what type of neurologic disorder?
- A. Hypothalamic disorder
- B. Demyelinating disease
- C. Brainstem deficit
- D. Diabetic neuropathy
Correct Answer: B
Rationale: SERs detect slowed nerve conduction, common in demyelinating diseases like multiple sclerosis. They are not used for hypothalamic, brainstem, or diabetic neuropathy diagnoses.

A patient with lower back pain is scheduled for myelography using metrizamide (a water-soluble contrast dye). After the test, the nurse should prioritize what action?
- A. Positioning the patient with the head of the bed elevated 45 degrees
- B. Administering IV morphine sulfate to prevent headache
- C. Limiting fluids for the next 12 hours
- D. Helping the patient perform deep breathing and coughing exercises
Correct Answer: A
Rationale: Elevating the head 30-45 degrees post-myelography prevents contrast dye irritation in the brain, reducing headache risk. Fluids are encouraged, morphine is not standard, and breathing exercises are unnecessary.
A patient is scheduled for a myelogram and the nurse explains to the patient that this is an invasive procedure, which assesses for any lesions in the spinal cord. The nurse should explain that the preparation is similar to which of the following neurologic tests?
- A. Lumbar puncture
- B. MRI
- C. Cerebral angiography
- D. EEG
Correct Answer: A
Rationale: Myelography involves contrast injection via lumbar puncture, so preparation is similar. MRI, angiography, and EEG have different preparation requirements.
The nursing students are learning how to assess function of cranial nerve VIII. To assess the function of cranial nerve VIII the students would be correct in completing which of the following assessment techniques?
- A. Have the patient identify familiar odors with the eyes closed.
- B. Assess papillary reflex.
- C. Utilize the Snellen chart.
- D. Test for air and bone conduction (Rinne test).
Correct Answer: D
Rationale: The Rinne test assesses hearing, a function of cranial nerve VIII. Odor identification tests cranial nerve I, pupillary reflex tests III, IV, and VI, and the Snellen chart tests II.
The nurse is conducting a focused neurologic assessment. When assessing the patients cranial nerve function, the nurse would include which of the following assessments?
- A. Assessment of hand grip
- B. Assessment of orientation to person, time, and place
- C. Assessment of arm drift
- D. Assessment of gag reflex
Correct Answer: D
Rationale: The gag reflex assesses cranial nerves IX and X. Hand grip and arm drift evaluate motor function, while orientation assesses mental status, not cranial nerves.
The nurse is admitting a patient to the unit who is diagnosed with a lower motor neuron lesion. What entry in the patients electronic record is most consistent with this diagnosis?
- A. Patient exhibits increased muscle tone.
- B. Patient demonstrates normal muscle structure with no evidence of atrophy.
- C. Patient demonstrates hyperactive deep tendon reflexes.
- D. Patient demonstrates an absence of deep tendon reflexes.
Correct Answer: D
Rationale: Lower motor neuron lesions result in flaccid paralysis, muscle atrophy, and absent deep tendon reflexes due to disrupted nerve supply to muscles. Increased tone and hyperactive reflexes indicate upper motor neuron issues.
