Which of the following assessments should the nurse make to test a patient's cerebellar function? (Select all that apply.)
- A. Assess for graphesthesia.
- B. Perform the finger-to-nose test.
- C. Observe arm movement with gait.
- D. Check ability to push against resistance.
- E. Determine ability to sense heat and cold.
Correct Answer: B,C
Rationale: The cerebellum is responsible for coordination and is assessed by looking at the patient's gait and the finger-to-nose test. The other assessments will be used for other parts of the neurological assessment.

A patient has a lesion that affects lower motor neurons. During assessment of the patient's lower extremities, which of the following findings should the nurse expect?
- A. Spasticity
- B. Flaccidity
- C. Loss of sensation
- D. Hyperactive reflexes
Correct Answer: B
Rationale: Because the cell bodies of lower motor neurons are directly affected, a lesion results in flaccidity, loss of muscle tone, and decreased reflexes. Spasticity and hyperactive reflexes are associated with upper motor neuron lesions. Loss of sensation is related to sensory nerve damage, not motor neuron lesions.
The charge nurse is observing a novice staff nurse who is assessing a patient with a possible spinal cord lesion for sensation. Which of the following action indicates a need for further teaching about neurological assessment?
- A. The novice nurse asks the patient, 'Does this feel sharp?'
- B. The novice nurse tests for light touch before testing for pain.
- C. The novice nurse has the patient close the eyes during testing.
- D. The novice nurse uses an irregular pattern to test for intact touch.
Correct Answer: A
Rationale: When performing a sensory assessment, the nurse should not provide verbal clues. The other actions by the new nurse are appropriate.
The nurse is developing a plan of care for a patient with dysfunction of the cerebellum. Which of the following goals of care should the nurse include?
- A. Prevent falls.
- B. Stabilize mood.
- C. Enhance swallowing ability.
- D. Improve short-term memory.
Correct Answer: A
Rationale: 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.
After reviewing a patient's cerebrospinal fluid (CSF) analysis, which of the following results is most important for the nurse to communicate to the health care provider?
- A. Specific gravity 1.007
- B. Protein 6.5 g/L
- C. White blood cell (WBC) count 5 x 10^6/L
- D. Glucose 2.5 mmol/L
Correct Answer: B
Rationale: The protein level is high. The specific gravity, WBCs, and glucose values are normal.
Which of the following actions should the nurse implement to assess the functioning of the trigeminal and facial nerves (CN V and VII) in a patient?
- A. Apply a cotton wisp strand to the cornea.
- B. Have the patient read a magazine or book.
- C. Shine a bright light into the patient's pupil.
- D. Check for unilateral drooping of the eyelids.
Correct Answer: A
Rationale: 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.
