Chapter 56: Nursing Assessment: Nervous System
Test Bank
MULTIPLE CHOICE
1. When admitting an acutely confused
... [Show More] 20-year-old patient with a head injury, which action should the nurse take?
a. Ask family members about the patients health history.
b. Ask leading questions to assist in obtaining health data.
c. Wait until the patient is better oriented to ask questions.
d. Obtain only the physiologic neurologic assessment data.
When admitting a patient who is likely to be a poor historian, the nurse should obtain health history information
from others who have knowledge about the patients health. Waiting until the patient is oriented or obtaining only
physiologic data will result in incomplete assessment data, which could adversely affect decision making about
treatment. Asking leading questions may result in inaccurate or incomplete information.
2. Which finding would the nurse expect when assessing the legs of a patient who has a lower motor neuron lesion?
a. Spasticity
b. Flaccidity
c. No sensation
d. Hyperactive reflexes
ANS: B
Because the cell bodies of lower motor neurons are located in the spinal cord, damage to the neuron will decrease
motor activity of the affected muscles. Spasticity and hyperactive reflexes are caused by upper motor neuron
damage. Sensation is not impacted by motor neuron lesions.
3. The nurse performing a focused assessment of left posterior temporal lobe functions will assess the patient for
a. sensation on the left side of the body.
b. voluntary movements on the right side.
c. reasoning and problem-solving abilities.
d. understanding written and oral language.
The posterior temporal lobe integrates the visual and auditory input for language comprehension. Reasoning and
problem solving are functions of the anterior frontal lobe. Sensation on the left side of the body is located in the
right postcentral gyrus. Voluntary movement on the right side is controlled in the left precentral gyrus.
4. Propranolol (Inderal), a b-adrenergic blocker that inhibits sympathetic nervous system activity, is prescribed for a
patient who has extreme anxiety about public speaking. The nurse monitors the patient for
a. dry mouth.
b. bradycardia.
c. constipation.
d. urinary retention.
ANS: B
Inhibition of the fight or flight response leads to a decreased heart rate. Dry mouth, constipation, and urinary
retention are associated with peripheral nervous system blockade.
5. To assess the functioning of the trigeminal and facial nerves (CNs V and VII), the nurse should
a. shine a light into the patients pupil.
b. check for unilateral eyelid drooping.
c. touch a cotton wisp strand to the cornea.
d. have the patient read a magazine or book.
ANS: A
The trigeminal and facial nerves are responsible for the corneal reflex. The optic nerve is tested by having the
patient read a Snellen chart or a newspaper. Assessment of pupil response to light and ptosis are used to check
function of the oculomotor nerve.
6. Which action will the nurse include in the plan of care for a patient with impaired functioning of the left
glossopharyngeal nerve (CN IX) and the vagus nerve (CN X)?
a. Withhold oral fluid or foods.
b. Provide highly seasoned foods.
c. Insert an oropharyngeal airway.
d. Apply artificial tears every hour.
ANS: A
The glossopharyngeal and vagus nerves innervate the pharynx and control the gag reflex. A patient with impaired
function of these nerves is at risk for aspiration. An oral airway may be needed when a patient is unconscious and
unable to maintain the airway, but it will not decrease aspiration risk. Taste and eye blink are controlled by the facial
nerve.
7. An unconscious male patient has just arrived in the emergency department after a head injury caused by a
motorcycle crash. Which order should the nurse question?
a. Obtain x-rays of the skull and spine.
b. Prepare the patient for lumbar puncture.
c. Send for computed tomography (CT) scan.
d. Perform neurologic checks every 15 minutes.
ANS: B
After a head injury, the patient may be experiencing intracranial bleeding and increased intracranial pressure, which
could lead to herniation of the brain if a lumbar puncture is performed. The other orders are appropriate.
8. A patient with suspected meningitis is scheduled for a lumbar puncture. Before the procedure, the nurse will plan
to
a. enforce NPO status for 4 hours.
b. transfer the patient to radiology.
c. administer a sedative medication.
d. help the patient to a lateral position.
For a lumbar puncture, the patient lies in the lateral recumbent position. The procedure does not usually require a
sedative, is done in the patient room, and has no risk for aspiration.
9. During the neurologic assessment, the patient is unable to respond verbally to the nurse but cooperates with the
nurses directions to move his hands and feet. The nurse will suspect
a. cerebellar injury.
b. a brainstem lesion.
c. frontal lobe damage.
d. a temporal lobe lesion.
Expressive speech is controlled by Brocas area in the frontal lobe. The temporal lobe contains Wernickes area,
which is responsible for receptive speech. The cerebellum and brainstem do not affect higher cognitive functions
such as speech.
10. A 45-year-old patient has a dysfunction of the cerebellum. The nurse will plan interventions to
a. prevent falls.
b. stabilize mood.
c. avoid aspiration.
d. improve memory.
Because functions of the cerebellum include coordination and balance, the patient with dysfunction is at risk for
falls. The cerebellum does not affect memory, mood, or swallowing ability.
11. Which nursing diagnosis is expected to be appropriate for a patient who has a positive Romberg test?
a. Acute pain
b. Risk for falls
c. Acute confusion
d. Ineffective thermoregulation
A positive Romberg test indicates that the patient has difficulty maintaining balance with the eyes closed. The
Romberg does not test for orientation, thermoregulation, or discomfort.
12. The nurse will anticipate teaching a patient with a possible seizure disorder about which test?
a. Cerebral angiography
b. Evoked potential studies
c. Electromyography (EMG)
d. Electroencephalography (EEG)
Seizure disorders are usually assessed using EEG testing. Evoked potential is used for diagnosing problems with the
visual or auditory systems. Cerebral angiography is used to diagnose vascular problems. EMG is used to evaluate
electrical innervation to skeletal muscle.
13. Which nursing action will be included in the care for a patient who has had cerebral angiography?
a. Monitor for headache and photophobia.
b. Keep patient NPO until gag reflex returns.
c. Check pulse and blood pressure frequently.
d. Assess orientation to person, place, and time.
Because a catheter is inserted into an artery (such as the femoral artery) during cerebral angiography, the nurse
should assess for bleeding after this procedure. The other nursing assessments are not necessary after angiography.
14. Which equipment will the nurse obtain to assess vibration sense in a diabetic patient who has peripheral nerve
dysfunction?
a. Sharp pin
b. Tuning fork
c. Reflex hammer
d. Calibrated compass
Vibration sense is testing by touching the patient with a vibrating tuning fork. The other equipment is needed for
testing of pain sensation, reflexes, and two-point discrimination.
15. Which information about a 76-year-old patient is most important for the admitting nurse to report to the patients
health care provider?
a. Triceps reflex response graded at 1/5
b. Unintended weight loss of 20 pounds
c. 10 mm Hg orthostatic drop in systolic blood pressure
d. Patient complaint of chronic difficulty in falling asleep
Although changes in appetite are normal with aging, a 20-pound weight loss requires further investigation.
Orthostatic drops in blood pressure, changes in sleep patterns, and slowing of reflexes are normal changes in aging.
16. The charge nurse is observing a new staff nurse who is assessing a patient with a traumatic spinal cord injury for
sensation. Which action indicates a need for further teaching of the new nurse about neurologic assessment?
a. The new nurse tests for light touch before testing for pain.
b. The new nurse has the patient close the eyes during testing.
c. The new nurse asks the patient if the instrument feels sharp.
d. The new nurse uses an irregular pattern to test for intact touch.
When performing a sensory assessment, the nurse should not provide verbal clues. The other actions by the new
nurse are appropriate.
17. Which cerebrospinal fluid analysis result will be most important for the nurse to communicate to the health care
provider?
a. Specific gravity 1.007
b. Protein 65 mg/dL (0.65 g/L)
c. Glucose 45 mg/dL (1.7 mmol/L)
d. White blood cell (WBC) count 4 cells/mL
The protein level is high. The specific gravity, WBCs, and glucose values are normal.
18. A 39-year-old patient with a suspected herniated intervertebral disc is scheduled for a myelogram. Which
information is most important for the nurse to communicate to the health care provider before the procedure?
a. The patient is anxious about the test.
b. The patient has an allergy to shellfish.
c. The patient has back pain when lying flat.
d. The patient drank apple juice 4 hour [Show Less]
