  1. Which component of the Glasgow Coma Scale (GCS) assesses the patient's ability to follow commands?

    Answer: Motor response

    The motor response component of the GCS evaluates the patient's best motor function, including the ability to follow commands.

  2. A CNRN nurse notes that a patient's pupils are 6 mm and non-reactive bilaterally. This finding is MOST consistent with:

    Answer: Midbrain herniation

    Bilateral fixed and dilated pupils indicate midbrain herniation due to compression of the oculomotor (CN III) nerves.

  3. When performing a neurological assessment, the nurse tests the patient's ability to identify objects by touch alone. This evaluates which sensory function?

    Answer: Stereognosis

    Stereognosis is the ability to identify objects by touch without visual input, testing parietal lobe sensory integration.

  4. Which cranial nerve is tested when the nurse asks the patient to shrug their shoulders against resistance?

    Answer: CN XI

    Cranial nerve XI (spinal accessory nerve) innervates the sternocleidomastoid and trapezius muscles, tested by shoulder shrug resistance.

  5. A patient exhibits decerebrate posturing. The nurse understands this involves:

    Answer: Extension and internal rotation of all extremities

    Decerebrate posturing involves rigid extension, adduction, and internal rotation of all extremities, indicating severe brainstem injury.

  6. Which intracranial pressure (ICP) waveform component reflects ventricular compliance and is normally the smallest peak?

    Answer: P3 (dicrotic wave)

    P3 (dicrotic wave) reflects closure of the aortic valve and is normally the smallest of the three ICP waveform peaks.
